Tool details

Spike is a "conversational email" client built by an Israeli team: it rearranges traditional email threads into iMessage-style chat bubbles and layers on a unified inbox, team collaboration and a built-in AI enhancement layer.

Core capabilities

  • Conversational email: strips signatures and repeated quoting, groups by person rather than by subject, so long multi-account threads stay tidy
  • Unified inbox: aggregates Gmail, Outlook, Microsoft 365, Exchange, iCloud, Yahoo and IMAP
  • Teamspace collaboration: channels, shared inboxes, tasks, calendar and one-click audio/video meetings
  • Spike AI: one-click drafting and replies, thread and attachment summaries, real-time translation, and AI Feed for batch-processing unread mail
  • Full platform coverage: iOS, Android, macOS, Windows and Web are all covered
  • Privacy: AES-256 per-item encryption, with a commitment not to sell or monetise user data

Use cases Individuals and 3–20 person teams used to the WhatsApp / Slack idiom, heavy multi-mailbox users, and freelancers and startup teams who want email plus light collaboration in one place.

Distinct advantages Within the conversational email niche, Spike has the broadest platform coverage and a unit price clearly lower than Superhuman and Front. But AI is an enhancement layer bolted on only in 2023, while the core chat-style email has existed since 2013; the free tier's AI is limited to 10 queries and excludes AI Feed, and full AI requires a paid tier. Be careful not to confuse it with Spark Mail by Readdle.

Editor's assessment G2 4.6 (about 262 reviews) and Capterra 4.7 (about 45 reviews) are well regarded, but Trustpilot is only 3.3–3.5 (about 167 reviews), with complaints centred on billing, refunds, support and signature replacement; App Store about 4.49 (about 4,300 reviews) and Google Play 4.05 (about 19,000 reviews). If you like the chat metaphor, it has few rivals; enterprise-grade compliance and search remain weak spots. This entry refers to spikenow.com — do not confuse it with similarly named products such as Spike Chunsoft or Spike.sh.

Additional notes

All prices are in USD and no cross-currency conversion is applied; the official pricing page defaults to annual billing and lists annual and monthly figures side by side. Free and Starter are permanently free tiers rather than trials; the official terms do not state a refund policy. Third parties also cite monthly figures of $5/$10, so refer to the official live pricing.

FAQ

Spike uses a freemium model, with Email App Free and Teamspace Starter (up to 3 people) as permanently free tiers. However, the free tier's Spike AI is limited to 10 queries and excludes AI Feed; full AI and unlimited mailboxes require an upgrade to a paid tier.
