Create Account

Join the InboxDays private beta with any email address — Gmail, Microsoft, iCloud, Fastmail, or a personal domain. You will verify your email, then connect a mailbox when you are ready to read mail.

I have read and agree to the InboxDays Beta Programme Terms (version 2026-08-10), including that this is pre-release software provided without warranty.

Recommended for beta. Creates a password (and optional passkey later). We send a verification link to your inbox via SES — check spam if it is slow.

Optional one-click

Google / Microsoft one-click needs those identity providers enabled in Keycloak. If a button fails, use Continue with email instead — you can still connect Gmail, Microsoft 365, iCloud, or IMAP after sign-up.

By creating an account, you also agree to InboxDays' Terms of Service, Privacy Policy, and Acceptable Use Policy. Google sign-in is also subject to our Google API Limited Use disclosures.
