# Send mail with Gmail in Duaer

In Duaer, Gmail defaults to Authentication OAuth2, Resource Message, and Operation Send. Email Type defaults to HTML. You need a gmailOAuth2 credential.
## Send a message

1. Create a gmailOAuth2 credential (or switch to Service Account / googleApi in the panel).
2. Search for Gmail, connect it after the previous node, and select that credential.
3. Leave Resource on Message and Operation on Send.
4. Set To, Subject, and Message. Leave Email Type on HTML (or switch to Text).
5. Select Execute step.

Under Message you also get Get, Get Many, Delete, Reply, and Add Labels.

For SMTP, see [Send mail with Send Email in Duaer](/build/send-email.md). To receive mail, see [Receive mail with Email Trigger (IMAP) in Duaer](/build/email-trigger-imap.md).
