If you’ve recently changed your email password or there’s an issue with your email provider, Polymail will prompt you to re-authenticate your login credentials. Until you do, your account will stop syncing and you won’t be able to send emails.

On Polymail Web or Desktop:

• A red banner will appear at the top of the main app window notifying you of the issue.

• In Settings > Accounts, the affected email address will be highlighted in red with a “Re-authenticate” button next to it.

• You can click either the blue “Re-authenticate” button in Settings or the “Click here” link in the red banner.

• This will open a new browser tab where you can select your email address or enter your password again to complete re-authentication.

On the iOS App:

• A banner will appear at the top of your screen prompting you to re-authenticate.

• Tap the banner, and it will open in your browser, where you can enter your updated credentials.

• Once re-authenticated, Polymail will automatically resume syncing your emails and restore sending capabilities.
