What is the Gmail SMTP server?

The Gmail SMTP server is smtp.gmail.com. Connect on port 465 with SSL or port 587 with STARTTLS, sign in with your full Gmail or Google Workspace address, and use an app password or Sign in with Google instead of your normal password.

Personal Gmail

Same server and ports, 500 emails a day, app password after 2-Step Verification.

Google Workspace

Same server, 2,000 a day on paid plans, plus a relay service admins can open.

Other providers are on the SMTP settings lookup.

Setup

Connect Gmail in five steps.
Two minutes with an app password.

Google blocks plain password sign-in from apps. The app password is the fix.

App password setup

Five steps, then a test email

1Turn on 2-Step VerificationGoogle Account, Security. App passwords only exist once it is on.
2Create an app passwordSearch "App passwords" in your Google Account, name it after the app, copy the 16 digit code.
3Enter the SMTP settingssmtp.gmail.com, port 587 with STARTTLS (or 465 with SSL), your full Gmail address as username.
4Paste the app passwordUse it where the app asks for a password. If the app offers Sign in with Google, use that instead.
5Send a test emailSend to an address you control on another provider and check it lands in the inbox.

Troubleshooting

Gmail SMTP errors.
And the fix for each.

The five codes behind most failed connections.

Gmail SMTP error lookup

535 5.7.8Username and Password not acceptedFix: Your Google password is refused over SMTP. Turn on 2-Step Verification and use a 16 digit app password, or pick Sign in with Google in the app.

534 5.7.9Application-specific password requiredFix: 2-Step Verification is on, so the app needs an app password instead of your normal one.

534 5.7.14Please log in through your web browserFix: Google flagged the sign-in. Sign in once on the web from the same network, then retry.

530 5.7.0Must issue a STARTTLS command firstFix: The app connected without encryption. Use 587 with STARTTLS or 465 with SSL.

550 5.4.5Daily user sending limit exceededFix: You hit the daily cap. Sending resumes within 24 hours. Spread volume over more inboxes instead of pushing one.

FAQ

Gmail SMTP questions

What are the Gmail SMTP settings?

Server smtp.gmail.com, port 465 with SSL or port 587 with STARTTLS, authentication on, your full Gmail address as the username, and an app password (or Sign in with Google) as the password. Incoming mail over IMAP uses imap.gmail.com on port 993 with SSL.

Should I use port 465 or 587 for Gmail?

Either works. Port 465 opens an SSL connection straight away; port 587 starts plain and upgrades with STARTTLS. Pick what your app supports. If one port times out, your network may block it, so try the other.

Why does Gmail reject my password over SMTP?

Google no longer lets apps sign in with just your account password. Use Sign in with Google if the app supports it, or turn on 2-Step Verification and create a 16 digit app password. Google Workspace accounts have required OAuth or app passwords since 1 May 2025.

Are the Google Workspace SMTP settings different from Gmail?

The server and ports are the same: smtp.gmail.com on 465 or 587. Workspace admins also get the SMTP relay service (smtp-relay.gmail.com, authenticated by IP address) and a restricted server (aspmx.l.google.com on port 25) that only delivers to Gmail and Workspace users.

How many emails can I send through Gmail SMTP?

Personal Gmail stops at 500 emails a day. Paid Google Workspace accounts get 2,000 messages a day per user, trial accounts 500, with 3,000 external recipients a day. The SMTP relay service allows up to 10,000 recipients per user a day.

Can I send cold email through Gmail SMTP?

You can connect a Workspace inbox to a sequencer with these settings, but the daily limit is a ceiling, not a target. Cold email keeps each inbox near 30 sends a day on separate lookalike domains, so volume comes from more inboxes, not from pushing one to its cap.

What does error 535 5.7.8 mean?

Username and Password not accepted. The app tried your normal Google password. Create an app password after turning on 2-Step Verification, or switch the app to Sign in with Google.
