If you send yourself an email, you might notice a yellow ribbon warning in Gmail that says, “Be careful with this message.”

This alert appears when the “To” and “From” email addresses are the same—essentially when you’re sending yourself a test email. It’s a default Gmail security measure and happens regardless of the platform (Flodesk or else) you’re using.

No! Only you will see this banner in Gmail. Your subscribers will not see any warnings when they receive your emails.

Yes—if you’re using a custom domain (e.g., you@yourdomain.com). You can authenticate your domain, which helps prevent this warning.

If you’re sending emails from a free email provider like gmail.com, yahoo.com, icloud.com, or me.com, you won’t be able to verify your domain or prevent the warning.

Using a custom domain isn’t just about avoiding warnings—it also helps:

• Make your emails look more professional

• Improve email deliverability

• Reduce the chances of your emails landing in spam

We highly recommend investing in a custom domain for the best email-sending experience!
