Custom SMTP via Gmail or Google Workspace

If you use Gmail as your primary email service provider, you can also have Enchant send email via Gmail.

Enchant can deliver outbound emails to Gmail via TLS encrypted SMTP. The SMTP settings are as follows:

Host: smtp.gmail.com
Port: 587
Username: Your email address
Password: Your password

535-5.7.8 Username and Password not accepted.

Sometimes Gmail will reject SMTP connections with the following error: 535-5.7.8 Username and Password not accepted.

Step 1: Make sure you are using the right password. The same error is raised when using the wrong password.

Step 2: Enable SMTP based password authentication. Head to this page and enable Allow Less Secure Apps. If it's already enabled, try flipping the flag off and on. If this option is not available on your account, head to the next step.

Step 3: Enable 2-Step Verification on the account. This will require you to use an extra authentication app to login to the account. Once you have enabled 2-Step Verification, you will be able to create an App Password for Enchant. Provide the app password in the sending/receiving settings.

Why is Enchant using a Less Secure authentication method?: Enchant uses a TLS encrypted SMTP connection to Gmail's mail servers. This is just as secure as you typing your password into Google's web form to login (which uses a TLS encrypted HTTP connection). However, Google now considers any form of password based authentication less secure.
