Why teams look beyond Missive
Missive has carved out a unique position in the team inbox space by blending email, chat, and task management into a single collaborative workspace. For teams tired of jumping between Gmail, Slack, and a task manager, Missive's unified approach makes a lot of sense.
But it's not the only tool tackling this problem, and it won't be the right fit for every team. Maybe you're already deep in the Google Workspace ecosystem and want something that layers over Gmail instead of replacing it. Maybe Missive's pricing feels steep for a small team. Or perhaps you need features Missive doesn't prioritize like live chat widgets, robust CRM capabilities, or AI-powered triage.
Whatever your reason for exploring alternatives, you've got solid options. From Front's polished team inbox to Hiver's Google Workspace integration, the shared inbox category has matured significantly in the past few years.
This guide breaks down the best Missive alternatives in 2026, covering everything from support ticket management to sales team collaboration.
Why Consider Missive Alternatives?
Common reasons teams switch from Missive
Missive does a lot right, but it's not a universal solution. Here's why teams go shopping for alternatives:
Google Workspace friction. If your team lives in Gmail, switching to Missive means abandoning that interface and workflow entirely. Some teams love this fresh start, but others find it disruptive. Tools like Hiver and Gmelius layer over Gmail, letting you keep the familiar interface while adding collaboration features. That's a lower-friction approach for teams already invested in Google's ecosystem.
Pricing can add up fast. Missive starts at around $14-18 per user per month depending on your plan. For a 10-person team, that's $140-180 monthly or roughly $1,680-2,160 annually. If you're a small team or startup watching costs, alternatives with lower per-seat pricing or more generous free tiers become attractive.
Support-specific features. Missive works for customer support teams, but it's a generalist tool. Dedicated support platforms like Zendesk or Help Scout offer features Missive lacks: canned responses libraries, customer satisfaction surveys, detailed SLA tracking, and support-focused reporting. If you're running a proper support operation, you might need those specialized tools.
Limited automation and workflows. Missive has rules and assignments, but it's not as robust as platforms built for complex routing and automation. Front's rule engine, for example, is more sophisticated. If you need emails automatically assigned based on complex criteria or workflows with multi-step approval processes, Missive might feel limiting.
No integrated live chat or website widgets. If you want customers to message you from your website and have those conversations flow into the same inbox as email, Missive doesn't do that natively. Tools like Zendesk, Front, and Help Scout include live chat widgets, consolidating more channels in one place.
The chat component feels half-baked to some teams. Missive's internal chat exists, but it's not as full-featured as Slack or Microsoft Teams. If your team needs threaded conversations, robust search, extensive integrations, or video calls, you'll probably end up using Slack anyway, which defeats the purpose of Missive's unified approach.
Interface preferences vary. Some people love Missive's design. Others find it cluttered or prefer different workflows. Front has a reputation for better UX. Superhuman offers blazing speed and keyboard shortcuts. Interface fit is subjective but real.
That said, Missive's approach of unifying email, chat, and tasks resonates with teams who want fewer tools and less context-switching. But if the above pain points sound familiar, keep reading.
What Makes a Good Missive Alternative?
Key features to evaluate in team inbox tools
When you're comparing Missive alternatives, focus on these criteria:
Shared inbox fundamentals. At minimum, you need multiple people viewing and responding to the same email accounts without stepping on each other's toes. Look for assignment features, internal notes, collision detection (so two people don't reply to the same message), and clear status indicators.
Integration with your existing stack. If you use Slack, does the tool notify you there? If you're on Google Workspace or Microsoft 365, how well does it integrate? Check for connections to your CRM, help desk, or project management tools. The best tools slot into your workflow instead of forcing you to change it.
Channel consolidation. Email is the baseline, but can the tool also handle social media messages, live chat, SMS, or other channels? If you're managing support across multiple channels, consolidation becomes critical. Missive does email and some integrations; alternatives like Front and Zendesk go further.
Automation and routing. Can you automatically assign incoming messages based on keywords, sender, or other criteria? Can you set up workflows for escalation or approval? The sophistication here varies wildly between tools.
Reporting and analytics. You need visibility into response times, message volume, individual performance, and bottlenecks. Support-focused tools excel here. Generalist tools often have basic reporting that might not cut it for data-driven teams.
Pricing model and scalability. Per-user pricing, tiered plans, free tiers, and how costs scale as you grow all matter. A cheap tool for 5 people might get expensive at 50. Look at total cost of ownership, not just the starting price.
Customer support use case fit. If you're primarily doing customer support, tools purpose-built for that (Help Scout, Zendesk, Groove) will have features generalist tools lack. If you're doing sales or internal collaboration, different priorities apply.
User experience and learning curve. A powerful tool nobody uses because it's too complex is worthless. Consider how easily your team will adopt it. Missive has a learning curve; some alternatives are simpler, others more complex.
1. Front
Best Full-Featured Alternative: Front
Front is probably the most direct Missive competitor. Both are modern team inboxes that consolidate multiple channels, enable collaboration, and aim to replace fragmented communication tools.
Front's interface is polished and intuitive. Many teams find it easier to navigate than Missive, with a cleaner layout and better visual hierarchy. The inbox view feels more like a modern app than traditional email, which helps teams transition from personal email habits to collaborative workflows.
Channel coverage is extensive. Beyond email, Front handles SMS, social media (Twitter, Facebook), live chat via a website widget, and various integrations. If you're managing customer conversations across multiple platforms, Front consolidates them better than Missive.
The rules engine is sophisticated. You can automatically route messages, assign them to specific people or teams, tag conversations, and trigger workflows based on complex conditions. This automation depth exceeds what Missive offers, making Front better suited for high-volume environments or teams with complex routing needs.
Collaboration features include internal comments (like Missive), shared drafts where multiple people can edit a response before sending, and assignments with clear ownership. The collision detection ensures two people don't reply to the same message simultaneously.
Analytics and reporting are strong. Front provides detailed metrics on response times, conversation volume, individual and team performance, and SLA compliance. If you need to track support KPIs or demonstrate team productivity, Front delivers the data.
Integrations are plentiful. Front connects to Salesforce, HubSpot, Asana, Jira, and dozens of other tools. The API is robust if you need custom integrations.
Pricing is comparable to Missive, starting around $19 per user per month for the core plan. It's not cheap, but it's in the same ballpark. Teams switching from Missive won't see dramatic cost savings, though Front's feature set might justify the similar price better.
Downsides? Front can feel overwhelming initially. There are a lot of features, and the learning curve is real. Missive, for all its capabilities, has a slightly simpler mental model. Front's power comes with complexity.
The internal chat is still secondary. Like Missive, Front's team chat features exist but don't replace Slack for most teams. If unified communication was a major Missive selling point, Front has the same limitation.
Some users report that Front can feel sluggish with very large inboxes or heavy integration usage. Performance varies, but it's something to test during trials.
Best for teams that need robust automation, multi-channel support, and detailed analytics. If you're outgrowing Missive's capabilities or need better reporting, Front is the logical next step. It's especially strong for customer support teams and sales teams managing high email volume.
2. Hiver
Best for Google Workspace Teams: Hiver
Hiver takes a radically different approach from Missive. Instead of replacing Gmail, it layers collaboration features directly over the Gmail interface. For teams deep in Google Workspace, this is clutch.
You stay in Gmail. Hiver adds a sidebar and additional features, but your core email interface remains Gmail. This means zero learning curve for the email part. Your team already knows how Gmail works; Hiver just adds shared inbox capabilities, assignments, and collaboration tools on top.
Shared mailboxes work seamlessly with Google Groups or shared accounts. Assign emails to team members, add internal notes, track status (open, pending, closed), and set up collision alerts, all without leaving Gmail. The integration feels native, not bolted-on.
Automation is solid. Create rules to auto-assign emails based on sender, subject, keywords, or other criteria. Set up templates for common responses. Build workflows for email approvals or escalations. It's not as deep as Front's automation, but it covers most common use cases.
The analytics dashboard provides metrics on response times, team workload, and email volume. It's not as comprehensive as dedicated support platforms, but it's sufficient for most teams tracking basic performance.
Pricing starts lower than Missive and Front, around $15 per user per month for the Lite plan, with more advanced features in higher tiers. For Google Workspace teams specifically, the value proposition is strong because you're enhancing your existing Gmail investment rather than replacing it.
Collaboration beyond email is limited. Hiver focuses on email and doesn't consolidate other channels like social media or live chat. If you need multi-channel support, you'll need additional tools.
The Google Workspace lock-in is real. Hiver only works with Gmail. If your organization uses Outlook or mixed email clients, Hiver is a non-starter. This is great if you're all-in on Google, but it's a limitation compared to platform-agnostic tools like Missive or Front.
The interface, while functional, looks a bit dated compared to modern alternatives. It works, but it's not as visually polished as Front or Missive. If UX and aesthetics matter to your team, this might be a minor annoyance.
Live chat and phone support are available but require higher-tier plans. The base plan is email-focused, which is fine if that's all you need but limiting if you're trying to consolidate channels.
Best for teams already using Google Workspace who don't want to abandon Gmail. If your team loves Gmail and just needs collaboration features, Hiver is the lowest-friction option. It's particularly popular with HR teams, operations teams, and small support teams that handle moderate email volume.
3. Help Scout
Best for Customer Support: Help Scout
Help Scout is purpose-built for customer support, which makes it a different beast than the more generalist Missive. If your primary use case is support tickets and customer communication, Help Scout's focused approach might be exactly what you need.
The shared inbox is clean and support-oriented. Conversations are organized by customer, so you see the full history of interactions with each person. This customer-centric view is more intuitive for support teams than generic email threading.
Internal notes and @mentions let your team collaborate on responses without customers seeing the back-and-forth. Multiple people can work on complex support issues, tagging in specialists as needed.
The knowledge base integration is genuinely useful. Help Scout includes a built-in help center and docs platform. When customers email common questions, you can point them to relevant articles. Over time, this reduces ticket volume by enabling customer self-service.
Automated workflows handle common scenarios. Auto-respond to new tickets, route specific types of questions to specialized team members, tag conversations automatically, and escalate based on criteria you define. The automation is more support-focused than Missive's general rules.
Customer satisfaction surveys are built-in. After closing a ticket, Help Scout can automatically ask customers to rate their experience. This feedback helps you track support quality and identify problem areas.
Reporting focuses on support metrics: first response time, resolution time, customer satisfaction scores, ticket volume trends, and individual agent performance. If you're running a support operation, these metrics are essential. Missive and other generalist tools often lack this level of support-specific analytics.
Integrations cover common support stack tools: Slack for notifications, Salesforce and HubSpot for CRM, Jira for bug tracking, and 80+ other apps. The API is well-documented if you need custom connections.
Pricing starts around $20 per user per month for the Standard plan, slightly higher than Missive. The Plus plan at $35-40 per user per month adds more advanced features. For dedicated support teams, the cost is justified by the support-specific features.
Limitations? Help Scout is email and messaging focused. If you need to manage social media channels or other communication types, you'll need additional tools. It's not trying to be an all-in-one communication hub like Missive aims to be.
The internal team chat is basically non-existent. Help Scout is for customer communication, not internal team messaging. You'll still need Slack or similar for internal chat.
It's overkill if you're not doing customer support. Sales teams or general business email collaboration won't benefit from Help Scout's support-specific features. Stick with Missive or Front for non-support use cases.
Best for customer support teams that want a purpose-built tool instead of a generalist inbox. If you're running support for a SaaS product, e-commerce store, or any business with significant customer service volume, Help Scout's focused feature set beats general-purpose alternatives.
4. Gmelius
Best Gmail-Based CRM: Gmelius
Gmelius is similar to Hiver in that it brings team collaboration to Gmail without replacing it. The difference is that Gmelius positions itself more as a CRM and project management layer on top of email, not just a shared inbox.
The Gmail integration is deep. Like Hiver, Gmelius works inside Gmail, so your team stays in the familiar interface. You get shared mailboxes, email assignments, internal notes, and collision detection without leaving Gmail.
Kanban boards for email are unique. You can view your shared inbox as a Kanban board, dragging emails between columns representing different stages (New, In Progress, Waiting, Closed). This visual workflow appeals to teams that think in terms of pipelines and processes.
CRM features set Gmelius apart from pure shared inbox tools. Track deals, manage customer relationships, and link emails to contact records. For small sales teams or teams that need light CRM functionality without paying for full Salesforce, this is valuable.
Automation and sequences support outbound workflows. Set up email sequences for prospecting, follow-ups, or onboarding. Schedule emails to send at optimal times. Create rules to automatically organize and route incoming messages. This makes Gmelius stronger for sales and outbound use cases than most Missive alternatives.
Shared labels and tags in Gmail become collaborative. Your team can use the same labeling system to organize conversations, and everyone sees the updates in real-time.
Pricing starts around $10-12 per user per month, making it one of the more affordable alternatives. The lower cost makes it attractive for small teams or startups.
Integrations are decent but not as extensive as Front or Help Scout. You get Slack, Trello, Asana, and other common tools, but the marketplace is smaller.
The interface can feel cluttered. Adding Gmelius features to Gmail's already-busy interface creates visual complexity. Some users love having everything in one place; others find it overwhelming.
Like Hiver, Gmelius is Google-only. If you're not on Google Workspace, this tool isn't an option. And if your team uses mixed email clients, you'll have problems.
The support-specific features are limited compared to dedicated platforms. Gmelius can handle support email, but it lacks customer satisfaction surveys, detailed support analytics, and help center integration that tools like Help Scout provide.
Best for small teams using Google Workspace who need shared inbox plus light CRM and project management features. If you're a sales team or a team that does both sales and support in Gmail, Gmelius offers more than pure shared inbox tools at a reasonable price.
5. Zendesk
Best Enterprise Support Platform: Zendesk
Zendesk is the 800-pound gorilla of customer support platforms. It's way more than a shared inbox, which makes it both powerful and potentially overkill depending on your needs.
The ticketing system is enterprise-grade. Every customer interaction becomes a ticket with full history, status tracking, priority levels, and assignees. For large support operations, this structure is essential. For small teams, it might be more than you need.
Multi-channel support is comprehensive. Email, live chat (via Zendesk Chat or the integrated Messaging widget), phone support, social media, and even messaging apps like WhatsApp all flow into the same ticketing system. If Missive's limited channel support was a pain point, Zendesk solves that completely.
The knowledge base and help center features are robust. Build a self-service portal where customers find answers before contacting support. Track which articles are most helpful, identify knowledge gaps, and reduce ticket volume over time.
Automation and workflows are sophisticated. Trigger auto-responses, route tickets based on complex rules, escalate to managers after specific conditions, integrate with external systems via webhooks, and build multi-step workflows. This depth exceeds what Missive, Front, or other shared inbox tools offer.
Reporting and analytics are extensive. Track every metric imaginable: ticket volume, response times, resolution times, customer satisfaction, agent productivity, and custom reports. The dashboard is customizable, and you can export data for deeper analysis.
Integrations number in the hundreds. Salesforce, Jira, Slack, Microsoft Teams, and virtually every business tool has a Zendesk integration. The API is powerful and well-documented.
Pricing starts around $19-25 per agent per month for the Suite Team plan, but it scales up quickly. Advanced features, more agents, and add-ons can push costs to $50-150+ per agent monthly. For small teams, this gets expensive fast. For large support operations, it's standard.
The learning curve is steep. Zendesk is a complex platform with countless features and configuration options. Onboarding takes time, and you might need dedicated admin resources to manage it properly. Missive and simpler alternatives are much faster to deploy.
It's overkill for small teams or non-support use cases. If you're a 5-person team doing general business email, Zendesk's enterprise features will feel like using a sledgehammer to crack a nut. It's built for support teams with dozens or hundreds of agents.
The interface feels corporate and dated compared to modern alternatives like Front or Missive. It works, and it's functional, but it's not as visually appealing or intuitive as newer tools.
Best for established support teams with high ticket volume, multiple channels, and the need for enterprise-grade features. If you're running support for a growing SaaS company, e-commerce business, or any organization where customer support is a core function, Zendesk's capabilities justify the complexity and cost. Small teams should look elsewhere.
6. Superhuman
Best for Email Power Users: Superhuman
Superhuman is a completely different take on email. It's not a team collaboration platform like Missive; it's a supercharged personal email client built for speed and keyboard shortcuts. But in the last year, they've added team features that make it relevant for some Missive use cases.
The speed is genuinely impressive. Superhuman is blazing fast, with instant search, near-zero load times, and keyboard shortcuts for everything. If you find traditional email clients sluggish, Superhuman feels like a revelation.
Keyboard-first design means you can process email without touching your mouse. Every action has a shortcut. Power users who prefer keyboard navigation love this. People who rely on mouse clicks might find it frustrating.
The triage features help you reach inbox zero. Snooze emails to reappear at the right time. Split your inbox into Important and Other (like Gmail's Priority Inbox). Use reminder triggers to follow up if someone doesn't reply. These features help you stay on top of high email volume.
Recent team features include shared drafts, the ability to assign emails to teammates, and email delegation. If you're on a sales team or executive team dealing with shared accounts or forwarded customer emails, these features help coordinate responses.
AI features do auto-categorization, email summaries, and suggested replies. The AI triage can surface important emails and help you prioritize. This is useful for executives or salespeople drowning in volume.
The interface is beautiful and minimal. Superhuman looks and feels premium, with thoughtful design details throughout. If aesthetics and user experience matter to you, it's one of the best-looking email clients available.
Pricing is the elephant in the room. Superhuman costs $30 per user per month. That's roughly double Missive and many alternatives. For individual power users or high-value team members (executives, top salespeople), the productivity gains might justify it. For entire teams, the cost adds up quickly.
The team collaboration features are limited compared to true shared inbox platforms. You can assign emails and share drafts, but you're missing features like internal notes, detailed analytics, customer satisfaction tracking, and the multi-channel support that platforms like Front or Zendesk offer.
It's Gmail and Outlook only. Superhuman works with Gmail and Microsoft 365 accounts. If you use other email providers, you're out of luck.
The keyboard shortcut requirement is polarizing. People either love it or hate it. There's no in-between. If your team isn't willing to learn keyboard shortcuts, Superhuman's main value proposition disappears.
Best for high-volume email users who prioritize speed and efficiency over collaboration features. Sales teams, executives, and consultants who live in email might find Superhuman worth the premium price. It's not a Missive replacement for full team collaboration, but for certain roles, it's phenomenal.
7. Zoho Desk
Best Budget Support Platform: Zoho Desk
Zoho Desk is a customer support platform that competes with Zendesk and Help Scout but at a significantly lower price point. If you're looking for support-specific features without enterprise-level costs, Zoho Desk is worth considering.
The ticketing system covers all the basics. Email becomes tickets, you can assign them to agents, track status, set priorities, and maintain full conversation history. It works well for support teams transitioning from shared inboxes to proper ticketing.
Multi-channel support includes email, social media (Twitter, Facebook), live chat, phone, and web forms. Consolidating these channels into one platform reduces the tool sprawl that comes from managing each channel separately.
Automation through workflows and blueprints handles ticket routing, auto-responses, escalations, and status updates. The automation isn't as sophisticated as Zendesk but covers most common support scenarios adequately.
The knowledge base lets you build a self-service help center. Customers can search for answers before creating tickets, reducing your support load. Analytics show which articles are helpful and which topics generate the most tickets.
AI features (in higher tiers) include sentiment analysis, suggested responses, and automated ticket categorization. The AI isn't as advanced as some competitors, but it helps teams work more efficiently.
Integrations with other Zoho products are seamless. If you use Zoho CRM, Zoho Projects, or other Zoho suite tools, everything connects naturally. Third-party integrations exist for Slack, Salesforce, Jira, and others, though the marketplace is smaller than Zendesk's.
Pricing is the main draw. Zoho Desk starts at around $7-10 per agent per month for the Standard plan, roughly half the cost of Help Scout and significantly cheaper than Zendesk. For price-sensitive teams, this makes a real difference.
The interface feels more dated than modern alternatives. It's functional but not beautiful. Teams coming from tools like Missive or Front might find the UX a step backward aesthetically.
Customization and advanced features lag behind Zendesk. If you need complex workflows, extensive custom fields, or deep integration with enterprise systems, Zoho Desk might feel limiting.
The reporting is decent but not as comprehensive as enterprise platforms. You get the metrics that matter (response time, resolution time, ticket volume), but advanced analytics and custom reporting require higher-tier plans.
Support quality varies. Some users report excellent support from Zoho; others have had frustrating experiences. It's not as consistently praised as Help Scout's support or as expected with Zendesk's premium tiers.
Best for small to mid-sized support teams that need ticketing and multi-channel support without paying Zendesk prices. If you're already using other Zoho products, the integration value is high. It's a solid middle-ground option between shared inboxes and enterprise support platforms.
How to Switch from Missive
Making the transition to a new team inbox
Switching from Missive to an alternative involves more than just changing tools. Here's how to make the transition smooth for your team:
Map your current workflows first. Document how you currently use Missive: which email accounts you share, how you assign messages, what rules and automation you've set up, and which integrations you rely on. This inventory helps you evaluate whether alternatives support the same workflows.
Choose based on your primary use case. If you're mainly doing customer support, prioritize support-focused tools (Help Scout, Zendesk). If you're in Google Workspace, Gmail-native tools (Hiver, Gmelius) reduce friction. If you need multi-channel management, Front or Zendesk make sense. Match the tool to the job.
Use trial periods strategically. Most alternatives offer 14-30 day trials. Test with your actual team and real email volume, not just as an individual exploring features. Have multiple team members use it for a week to assess the learning curve and daily usability.
Plan the data migration. Email history might or might not transfer depending on the platforms involved. Some tools import from Gmail or Outlook natively. Others might require manual migration or accepting that old emails stay in the old system. Clarify this before committing.
Run parallel for a week. Don't switch cold turkey. Have your team use both Missive and the new tool simultaneously for a few days. This reduces risk and lets people get comfortable without pressure.
Recreate your automations and rules. Most tools don't import rules from other platforms. You'll need to rebuild your automation from scratch. This is a good opportunity to eliminate rules you no longer need and optimize workflows.
Train your team properly. Block time for onboarding and training. Most platforms offer onboarding calls or training resources. Use them. The best tool fails if your team doesn't understand how to use it effectively.
Set up integrations early. If you rely on Slack notifications, CRM connections, or project management integrations, configure those before going live. Missing integrations create friction that can derail adoption.
Monitor the transition actively. Check in with your team daily during the first week. What's working? What's confusing? Where are people struggling? Address issues quickly before they become ingrained frustrations.
Cancel Missive thoughtfully. Make sure everything is working in the new system before canceling your Missive subscription. Export any data you want to keep. Download important conversation histories if needed.
Missive Alternatives FAQ
Common questions about switching from Missive
Is Front better than Missive?
Front has more advanced automation, better multi-channel support, and stronger analytics. If you're outgrowing Missive's capabilities or need robust reporting, Front is probably better. But it's also more complex to set up and learn. For smaller teams that want simplicity, Missive might still be the better fit despite having fewer features.
What's the best free alternative to Missive?
There isn't really a free equivalent to Missive's unified email-chat-tasks approach. For pure shared inbox, you can use Google Groups or Outlook shared mailboxes with manual coordination, but you lose the collaboration features. Your best bet is finding an alternative with a generous trial period (Front, Hiver, Help Scout) and testing thoroughly before committing.
Which alternative works best with Gmail?
Hiver and Gmelius both layer over Gmail, keeping the familiar interface while adding collaboration. Hiver is better for pure shared inbox needs. Gmelius adds CRM and project management features. If staying in Gmail is a priority, start with one of these two.
Can I import my Missive email history to another tool?
This depends on the destination tool. Most shared inbox platforms can import from Gmail or Outlook but not directly from Missive. Your best path is likely exporting emails from Missive back to Gmail or Outlook, then importing to the new tool. Some conversation history and internal notes might not transfer cleanly.
Do any alternatives have Missive's unified email and chat?
Front has internal comments and some messaging features, but like Missive, it doesn't fully replace Slack. Most teams end up using a dedicated chat tool (Slack, Teams) alongside their shared inbox tool. The "unified communication" dream is still mostly aspirational across the category.
What's the cheapest Missive alternative?
Gmelius starts around $10-12 per user per month. Zoho Desk is $7-10 for support teams. Hiver and Help Scout are in the $15-20 range. All of these are comparable or cheaper than Missive depending on which Missive plan you're comparing against. The cheapest option depends on whether you need support features, CRM, or just shared inbox.
Which Missive Alternative Should You Choose?
Final recommendations by use case
Your best Missive alternative depends on your team's specific needs and context.
Go with Front if you need powerful automation, multi-channel support, and detailed analytics. It's the most feature-rich direct alternative to Missive and worth the learning curve for growing teams.
Choose Hiver if you're deep in Google Workspace and want to keep working in Gmail. The low-friction integration makes adoption easy for teams that love Gmail.
Pick Help Scout if you're primarily doing customer support and want a purpose-built tool. The support-specific features and knowledge base integration justify the focus.
Try Gmelius if you need shared inbox plus light CRM and you're on Gmail. It's affordable and brings more features than pure inbox tools.
Consider Zendesk if you're running a serious support operation with high volume and multiple channels. The complexity and cost are worth it for teams where support is a core business function.
Test Superhuman if you have high-volume email power users who value speed over collaboration. It's expensive but phenomenal for the right people.
Look at Zoho Desk if you need support ticketing on a budget. It's not the prettiest, but it gets the job done at a fraction of Zendesk's cost.
For most teams leaving Missive, I'd start with Front (for general use) or Hiver (if you're on Google Workspace). Those two cover the broadest range of use cases with the least compromise.
