How to authenticate your email with SendGrid

Updated on July 28th, 2020

Flywheel now gives you the ability to authenticate your email through SendGrid on the Flywheel dashboard to improve your email deliverability.

Follow these steps to successfully complete sender authentication.


If you don’t see the Email Deliverability card you will need to reach out to Support for help. Just sign into the Dashboard and start a chat by pressing “Get Help” in the bottom right of the screen.

Go to the Advanced tab and look for the Email Deliverability card


Click 'Set up email'


Select the domain you want to authenticate

A pop-up will appear asking you to select the domain that you want to authenticate. Simply choose the domain from the dropdown and then click ‘Set Domain and Begin Setup’


Only the domains that have been added to your site will appear in the domain drop down. If you have not added your domain to Flywheel, you will not be able to authenticate that domain with SendGrid.

Add CNAME records to your DNS provider

After you select your domain, we’ll drop you onto a handy page that will explain how to add the CNAME records we give you to your DNS provider settings. Simply follow the instructions to add them, then come back to this page and click “Check Validation”.


Make sure you’ve added the CNAME records to your DNS provider before clicking this button, or you’ll get some validation errors when we check with SendGrid.


We'll make sure the validation worked

After you add the CNAME records to your DNS provider and click ‘Ok, I’m Done’, we’ll do some verifying on our end and then let you know whether or not the CNAME records were successfully added. If they weren’t, we’ll show you which records errored out so you can try and fix those with your DNS provider.


You might see an error because the CNAME records were added to your DNS provider incorrectly. Another reason can be due to a lag between when the CNAME records were updated and when they were actually verified. In that case, we recommend waiting a few minutes before trying again to see if that solves the issue. If it doesn’t, then contact support.


When everything validates successfully, you’ll be taken back to the Advanced page with a success banner and an indicator in the card that your domain was successfully authenticated.


You can always check the status of your domain authentication set-up in the Email Deliverability card on the Advanced tab. An orange banner says that you didn’t finish the set-up and a red banner means that your records didn’t validate correctly with your DNS provider. You would just want to double check that the CNAME records are correct and then try again.

That’s all there is to it! As always, if you run into any snags or have any questions, hit up support!
