Newsletter SMTP settings and connection test

Newsletters are sent through your company's own mail server (SMTP). Enter its details via the Newsletter card on the Settings page (host, port, encryption, username, password) and check them with Test connection.

Open it from the Newsletter card on the Settings page, or from the Settings quick action on the Newsletter overview. Enter:

• SMTP host – the mail server's address (your email provider gives you this),
• Port,
• Encryption – None, TLS or SSL,
• Username and Password.

The password is stored encrypted and is not shown again after saving. To keep it, leave the field blank.

Test connection tries to connect to the server with the values you entered – even before saving – and tells you whether it worked. If you test against a different server or username than the saved one, enter the password again.

Internal network or private addresses cannot be used as the SMTP host.

Until SMTP is configured, neither test emails nor campaigns can be sent. Configuring it requires the Newsletter module's manage permission.
