If a message doesn't have authentication data to confirm it was sent through Gmail, we'll warn you to protect your information.
Why the warning message shows up
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 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 account to your personal Gmail)
Option 1: The message seems suspicious
If you aren't sure the message was sent by the Gmail address you see, 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 a sender is legitimate, you can remove the warning from their messages in the future.
- On your computer, open Gmail.
- In the search box at the top, click Show search options
.
- In the "From" field, type the sender's email address.
- In the bottom right, click Create filter.
- Check Never send it to Spam.
- Click Create filter.
If you automatically forward messages from another email address, you can remove the warning from those messages.
- On your computer, open Gmail.
- In the top right, click Settings
See all settings.
- At the top, click the Accounts and Import or Accounts tab.
- In the "Send mail as" section, click Add another email address.
- Follow the steps on your screen.
Instead of seeing the warning on messages you forward, you'll see something like "[email protected] via anotherdomain.com."
Stop showing the warning to people I email
You can stop this warning from showing up to your recipients. To get started, choose the way you send Gmail messages:
Make sure 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 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.
