FAQ
Questions before you trust us with your inbox.
How is Calmo different from Gmail Gemini or Outlook Copilot?
Those tools help inside one ecosystem. Calmo is built around the daily outcome: reach zero inbox with a cross-provider digest, personal replies, and cleanup workflows.
Do you train AI models on my emails?
No. Calmo is designed to never train on your email content. Production access uses least-privilege permissions and privacy-first processing.
Which email providers will launch first?
Gmail and Outlook are first on May 20, 2026 (Pacific Time). Apple Mail and custom IMAP are planned for Pro users after the initial launch waves.
What happens after I join the waitlist?
You get a waitlist position and referral code. When launch waves open, Calmo will invite users in order, with referral priority applied.
Can I unsubscribe from newsletters in bulk?
Yes. Calmo identifies newsletters you rarely open and groups them into a one-click cleanup flow.
Will replies sound like me?
That is one of Calmo's core features. The assistant learns your writing patterns and drafts concise replies in your own tone.
Is there a free trial?
Yes. Both plans include a 7-day free trial, and waitlist referrals can unlock one free month after launch.
When is Calmo launching?
Calmo launches on May 20, 2026 (Pacific Time). Waitlist position and referrals determine priority for invite waves.
