When you send yourself an email, you may see a yellow ribbon warning pop up. This happens in Gmail inboxes no matter what sending platform you're using. First of all, rest assured that only you will see this banner in Gmail (none of your subscribers will!).
The warning is triggered in Gmail when the "to" and "from" email address are the same (so basically when you're sending yourself a test!). It only happens in Gmail, and it's not something Flodesk has any control over. In other words, we cannot remove, alter, or modify it.
The good news is that if you're using a custom domain (such as email@example.com), you can prevent this warning from popping up by authenticating your domain via DKIM. We highly recommend using a custom domain and verifying it anyway so that you have top-notch deliverability and sending stats.
For a detailed tutorial on how to verify your domain, check Authenticate your domain via DKIM.
Note: If you don't have a custom domain and you're sending your emails from a free email service such as yahoo.com, gmail.com, icloud.com, me.com, etc, you won't be able to verify your domain.
We highly recommend getting your own domain for sending email to make sure your sender name looks professional, your deliverability stats are as high as can be, and you stay out of the spam box as much as possible.
