If a message doesn't have authentication data to confirm that it was sent through Gmail, we'll warn you in order to protect your information.
Why the warning message appears
You'll see this warning if a sender looks like [email protected], but we can't verify that the email is actually coming from that Gmail account.
This can happen if the sender:
- Is sending emails from a fake Gmail account
- Emailed you from a website (for example, to share a news article)
- Sent an email that was automatically forwarded (for example, from your school/university account to your personal Gmail)
Option 1: The message seems suspicious
If you aren't sure that the message was sent by the Gmail address shown, follow these steps.
- In the warning message, click Report phishing.
- Do not provide any personal information or click any links in the email.
Option 2: The message is from a trusted sender
If you know that a sender is legitimate, you can remove the warning from their messages in the future.
- On your computer, open Gmail.

Settings.

Stop showing the warning to people who I email
You can stop this warning from appearing to your recipients. To get started, choose the way in which you send Gmail messages:
Make sure that you follow Gmail's setup guidelines for your mobile device.
If you sign in to Gmail and use the "send mail as" feature to send from a non-Google account, make sure that you use Google's SMTP servers.
Contact your administrator to set up email authentication.
If these steps don't work, you can report the issue.
