MailToaster is a third-party tool to send emails from your Gmail account. To connect your email account, you need to enter your password and use SMTP. But in some cases, Gmail may ask for additional confirmation from your side to make sure you know about the activity.
When Gmail asks for additional confirmation of connecting your email account, MailToaster will show you the following message:
Please log in with your web browser and then try again. Learn more at https://support.google.com/mail/?p=WebLoginRequired
Username and Password not accepted. Learn more at https://support.google.com/mail/?p=BadCredentials
Important. If you get such a message, your email account will have an error status, and MailToaster will stop all of your warmup activities.
How to resume your email account in MailToaster
To restore your email account in MailToaster, follow the Gmail instructions:
1. Log in to your Gmail account using your web browser.
2. Double-check if you have entered the correct password.
If you are using two-step verification, you need to generate an app password. If you are sure your password is correct, try to generate a new app password.
If you're not using two-step verification, check whether access to less secure apps is enabled.
3. Make sure your account connection tests are marked with green icons.
That's it! Now you can resume your account and continue warmup activities.
