How to Gmail smtp

Published November 1, 2024 · Updated July 22, 2026 · SMTP & Deliverability

Using Gmail's SMTP server is the quickest way to send email from an app, website, or script — the settings are free and already tied to your account. It works well for low volume, but Gmail's caps make it a starting point, not a destination. Here are the Gmail SMTP settings and how to use them.

Passwordan app password (if 2-step is on)
Use an app password: With 2-step verification on, your normal password will not work for SMTP — generate an app password in your Google account security settings.

Gmail SMTP caps out at roughly 500 emails a day (2,000 on Workspace). Fine for a form or a small script, but it will not carry a marketing campaign, and heavy use risks throttling your account.
