You need Gmail SMTP server settings if you want to send email from your Gmail account through an email software program.

SMTP (Simple Mail Transfer Protocol), while necessary for all email clients, is not the same for every email provider. Below are the specific details you need to set up SMTP for Gmail.


Gmail's Default SMTP Settings

  • Gmail SMTP server address:
  • Gmail SMTP username: Your Gmail address (e.g.
  • Gmail SMTP password: Your Gmail password
  • Gmail SMTP port (TLS): 587
  • Gmail SMTP port (SSL): 465
  • Gmail SMTP TLS/SSL required: yes

Remember that in addition to these email server settings, you need to let the email client receive/download mail from your Gmail account too. There's more information on that at the bottom of this page.

Gmail's Default POP3 and IMAP Settings

Downloading/receiving mail is done through either POP3 or IMAP servers. You can enable that type of access through Gmail's settings, in the Settings > Forwarding and POP/IMAP screen.

More Information on Gmail's SMTP Server Settings

The server settings for sending mail over Gmail are required only when using Gmail through an email client program. You shouldn't ever need to manually enter them anywhere if you're using Gmail online through a browser, like through

For example, if you need to use Gmail in Mozilla Thunderbird, you can manually enter the SMTP settings within Thunderbird's program options.

Since Gmail is so popular, some email programs might even provide these SMTP server details automatically while you're setting up your account.

Still Can't Send Mail Through Gmail?

Some email applications use older, less secure technologies to log you into your email account, and Google will block these requests by default.

If you can't send mail with your Gmail account for that reason, it's unlikely that you're entering the wrong SMTP settings. Instead, you'll get a message related to the security of the email client.

To solve this, log in to your Google account through a web browser and enable access through less secure apps through this link.

If that is not the reason Gmail isn't working in your email client, you may need to unlock it.
