TapSign Mail

Every email you send is cryptographically signed with your phone. Recipients verify instantly.

TapSign Mail shows you which emails really come from the person or company they claim to be, and lets you sign the emails you send with your phone. Verify: when a TapSign-signed email arrives in Gmail or Outlook on the web, a badge tells you whether it is genuine and unchanged. Companies that verified their domain show their name, and their automated mail (receipts, alerts) shows a blue Verified sender mark. Verifying needs no account. Sign: with a TapSign workspace, each email you send is approved on your own phone with your fingerprint or face. The signature proves it was you and that the text was not changed on the way. Company admins can invite their staff, and each person links their own phone. Privacy: TapSign never reads your mailbox and never stores your emails. The extension checks emails inside your browser; the text of your emails never leaves it.
