How to Gmail as smtp

Published October 12, 2024 · Updated July 21, 2026 · SMTP & Deliverability

Using Gmail as your SMTP server is the fastest way to get an app or website sending email - the credentials already exist and cost nothing. It works nicely for low volume, with a few things to know. Here is how to use Gmail as SMTP.

The settings

Point your app at smtp.gmail.com, port 587 (STARTTLS) or 465 (SSL), and authenticate with your Gmail address and an app password (required when 2-step verification is on).

What to watch

Daily cap - about 500 emails (2,000 on Workspace).
App password - your normal password will not work with 2-step on.
Shared reputation - deliverability is Gmail's, not yours.

Good for testing: Gmail as SMTP is perfect for development and low-volume sending. When you go to production at scale, a dedicated SMTP removes the caps and gives you a dedicated IP.
