How the extension works
Manage your addresses from the toolbar
Click the Tmailor icon to copy your address, create a random address, choose a name for a new address, or delete your current address. The popup lists up to 10 addresses. When you are signed out, you can open tmailor.com to restore an old address with its saved access token.
Use the download button next to the address to open Access Details on tmailor.com and save the access token you need to reopen the address later.
Fill sign-up forms in one step
Right-click an email field and choose "Fill with Tmailor address", or click in the field and press the keyboard shortcut. In Chrome and Edge you can also turn on a small Tmailor button inside email fields, for the sites you choose or for all websites. Your browser asks for permission first, and you can turn it off at any time.
- Default shortcut: Ctrl+Shift+7
- On Mac: Control+Shift+7
Tmailor Settings shows your current shortcut, and you can change it in the shortcut settings of your browser.
If Tmailor cannot fill a field, copy your address from the popup and paste it.
Alerts and settings you control
Get an alert when new mail arrives at your current address, see the unread count on the icon, and choose whether alerts show the sender. You can turn each of these off in Settings and switch the extension to another language at any time.
Get started in three steps
-
Install
Open the store page for your browser and click the install button.

-

Same address on the website

Saved to your account
While you are signed in, the addresses you use are saved to your account and are there when you sign in on another device.
Sign out together
Signing out in the extension also signs you out on tmailor.com, and the other way around.
