Here Are the SMTP Settings You Need to Set Up Gmail

Use another email client to send messages through your Gmail account

To synchronize your Gmail account with an outside email client, such as Outlook, give the server instructions for how to send your Gmail emails in the form of Simple Mail Transfer Protocol (SMTP) server settings. The settings are the same for any email provider you use with Gmail.

Default SMTP Settings for Gmail

As you set up an email client to synchronize with your Gmail account, a screen asks for your Gmail SMTP information.


Use these settings:

  • Gmail SMTP server address:
  • Gmail SMTP username: Your Gmail address (for example,
  • Gmail SMTP password: Your Gmail password
  • Gmail SMTP port (TLS): 587
  • Gmail SMTP port (SSL): 465
  • Gmail SMTP TLS/SSL required: Yes

Gmail's Default POP3 and IMAP Settings

SMTP settings are only for sending email; you'll also need to provide the settings for receiving emails. Receiving mail is done through POP3 or IMAP servers. Before you identify those settings in your email client, enable access through settings within Gmail by going to Settings > Forwarding and POP/IMAP.

Still Can't Send Mail Through Gmail?

Some email applications use older, less secure technologies to log you in to your email account, and Gmail blocks these requests by default. In these cases, you'll get a message related to the security of the email client.

To resolve this issue, log in to your Gmail account through a web browser and enable access through less secure apps. If that's not the reason Gmail isn't working in your email client, you may need to unlock it.
