About Spike

Spike is a commercial email platform that treats messages as chat-style conversations. It works with an existing email account, or with a business email created in Spike through its Teamspace and email hosting, and adds AI features, tasks, a calendar and a unified inbox for multiple accounts.

Inbox tools include conversational email, a priority inbox and fast search. For teams, Spike offers shared inboxes for customer email, collaborative docs, groups for private chats with teammates and partners, channels for public team discussions and one-click audio and video meetings. The company also publishes an email intelligence API for AI agents.

Spike has apps for Android, iOS, Windows and Mac and a pricing page, and it is a hosted service rather than self-hosted software. It suits founders, freelancers, consultants, remote teams and sales groups who prefer one app for email and team chat.
