Gmail SMTP and IMAP settings

SMTP and IMAP settings for personal Gmail and Google Workspace accounts, including the App Password requirement.

Outgoing mail (SMTP)

SMTP serversmtp.gmail.com
Port465 (SSL/TLS) or 587 (STARTTLS)
UsernameYour full Gmail address (you@gmail.com or you@yourdomain.com)
PasswordSee authentication note below

Incoming mail (IMAP)

IMAP serverimap.gmail.com
Port993
SecuritySSL/TLS

Authentication

If 2-Step Verification is enabled (it should be), your normal password will not work. Create an App Password in your Google Account and use that 16-character code as the SMTP/IMAP password.

Sending limits

Free Gmail caps at 500 recipients/day. Google Workspace allows 2,000/day. These are account limits, not inbox-safe cold-email volumes.

Good to know

  • IMAP must be enabled in Gmail settings (Settings, See all settings, Forwarding and POP/IMAP) before external clients can connect.

How to set up Gmail in your email tool

  1. Open your email client or sending tool and add a new account.
  2. For incoming mail, choose IMAP and enter server imap.gmail.com, port 993 (SSL/TLS).
  3. For outgoing mail, enter the SMTP server smtp.gmail.com on port 465 (SSL/TLS) or 587 (STARTTLS).
  4. Set the username to your full gmail address (you@gmail.com or you@yourdomain.com), and use the password described in the authentication note above.
  5. Save the account and send a test email to confirm it works.

Connecting is the easy part. Landing in the inbox is not.

Once Gmail is connected you can send, but whether your cold email reaches the inbox depends on SPF, DKIM, and DMARC authentication, your sender reputation, and proper domain warmup. Scheduler Zero handles warmup and deliverability so your emails actually land.
