How do I use SMASH Mail on mobile or in an external app?

SMASH Mail doesn't offer a downloadable mobile app, but it can be installed on your phone as an app using Progressive Web App (PWA) technology. You can also configure your mailbox in a third-party IMAP/SMTP-compatible app (Apple Mail, Outlook, Thunderbird) using a dedicated app password.

Install SMASH Mail as an app (PWA)

On iPhone (Safari): open SMASH Mail, tap Share, then "Add to Home Screen" and confirm.

On Android (Chrome): open SMASH Mail, tap the menu (⋮), then "Add to Home screen" and confirm.

You then get quick access from your home screen, a mobile-optimized interface, and push notifications.

Using a third-party mail client (IMAP/SMTP)

Because SMASH Mail uses a secure SSO connection, your main password cannot be used directly in a third-party app. You must first create an app password:

1. Open your SMASH Mail settings, then the Profile menu.
2. Go to App passwords.
3. Click Add a password, and give it a name (e.g., Outlook Mac, Mail iPhone).
4. Copy the generated password: it's only shown once.

Then, in the app (Apple Mail, Outlook, Thunderbird…), add a new account, enter your full email address, and when prompted for a password, use the app password you generated - not your main password. If the setup isn't automatic, the server for both receiving (IMAP) and sending (SMTP) is jmap.smash.mc, with your full email address as the username.

If the connection doesn't work

Check that you're using the app password (not your main password), that your email address is entered in full, and that the app password hasn't been revoked. You can delete an app password at any time from your mailbox settings; the connected app will then need to be reconfigured with a new one.
