Spike is a powerful collaborative tool.
Handling Slack-like comms, emails externally & video calls all in one place is no mean feit. But there tools that can do similar things and might be a base for your team to collaborate together, so let's explore. From ClickUp to Missive, let's breakdown what tools could be good for not just email, but handling all sorts that Spike offers up.
1. Superhuman
Best for Team & Individual Sales & Sharing
Superhuman is a good email client but more suited for emails, sharing emails & handling them faster with individuals & teams. This one doesn't do documents, or video calls, like Spike, but is a good bet if you're looking a solid way to triage and share emails as a team.
Pros
Good for collaboration and sharing emails within team
Handles emails really fast on a lot of devices & for Gmail/Google Workspace & Outlook
Leaders in email AI features compared to many other tools
Cons
Doesn't have Slack-like chat abilities
Comes quite expensive collectively for team pricing
2. Missive
Best for Sharing Emails & Customization
Missive is super flexible and one of the leading shared email services for small to medium sized companies, both for help desk & for communication. This one is super customizable and allows you to assign emails, chat about emails and make sense of what's coming in with plenty of tools like website support for help desk situations.
Pros
Fast and reliable compared to many options
Has plenty of AI features and rules for handling email administration - more customizable
Much more customizable for handling email
Cons
Doesn't handle documents but comes with loads of integrations and tools
Much more suited for being your team's base for knowledge & email management
3. Slack
Best for Team Communication
Slack is a well-known communication service for teams that is well worth considering if you need something known and easy. Slack has evolved a lot, but it might not live up to the nature of Spike that allows you manage the emails in your life.
Pros
Comes with Slack Connect for external communication
Recently adding more AI features in Pro for handling documents/lists (canvas) and beyond
Good reliable option for most people
Cons
Can get expensive for 90-day plus history access
Limited features for documents and external communication
4. ClickUp
Best for Team Chat & Projects
ClickUp does offer chat & many features for handling a project & documents that make it more of a collaborative workspace alternative to Spike. This is more of a fully fledged tool to replace Spike and isn't going to be as dedicated as Spike is with email.
Pros
Easy to use once you learn it
Comes with optional add-on of team chat
Has a lot of AI brain features for better management
This is more of a project management tool versus a direct Spike replacement

Can take a while to learn and adapt to it
Many people find ClickUp to be too flexible for their needs
