Google SMTP server info

Connect to SMTP server: smtp.gmail.com
Port: 465 if you use SSL
Port: 587 if you use TLS
Authentication: Your full Google Workspace email address and password.

SMTP server without SSL/TLS requirements

If your device or app does not support SSL or TLS, you can still send mail, but only to other Gmail or Google Workspace users. In this case, use the info below:

Connect to SMTP server: asmpx.l.google.com
Port: 25 (no SSL or TLS required)
Authentication: not required
Configure the SPF record for your domain with the IP address of the device/app

Steps to take after you complete your SMTP setup

In the Admin console, add the IP address to the Email Allowlist setting.

Sending limits

Note: with either setup, Gmail’s standard sending limits apply. You can review the sending limits in this article in Google’s Help Center.
