About Spike
Spike converts your inbox into chat-style conversations. Emails look and feel like Slack messages — no subject lines cluttering simple replies, no email chains stretching off the screen. The Priority Inbox learns what matters, and the team collaboration features are strong for small teams.
The most radical rethinking of the inbox since HEY. If you find traditional email exhausting, Spike's messaging-style view may feel like a breath of fresh air.
