What is Spike?

Spike is an email client that redesigns the inbox as a conversational, chat-style interface while remaining fully compatible with standard email (IMAP/Gmail/Outlook and other providers). It layers in AI features such as smart inbox prioritization, email summaries, and context-aware draft writing, alongside productivity tools like task tracking, calendar integration, snooze, voice messages, and unified search across accounts.

Pros & Cons of Spike

Pros

  • Chat-style interface makes high-volume inboxes feel faster to process than traditional email clients
  • Works with existing email accounts (Gmail, Outlook, IMAP) rather than requiring a new email address
  • Bundles collaboration features (shared inboxes, notes, video calls, voice messages) that would otherwise need separate apps
  • Free plan is usable on its own, not just a time-limited trial

Cons

  • Free plan caps AI usage at only 10 queries and limits storage to 1 GB
  • Advanced features like SAML-SSO and video call recording on the Teamspace Business plan are still listed as coming soon
  • Two separate pricing tracks (Email App vs Teamspace) can make it unclear which plan fits an individual vs a team
