Emails sent from our G Suite domain - tallyshorts.com - to anyone with a comcast.net email account are being marked as spam. (We're seeing "X-CAA-SPAM: F02000" in the mail headers).
We have SPF and DKIM records set that appear to be operating correctly. We've confirmed that our emails sent to other email providers are being delivered.
I'm hoping that a kind Comcast employee will take a look at this and provide a resolution.
Solved! Go to Solution.
Comcast security should be able to help you with this-------------------
Comcast Customer Security Assurance-------------------
Normal business hours (6:00 am to 2:00 am EST, 7 days a week)

I believe there's a typo in that phone number - it should be: 888-565-4329.
For others who have this issue with their email getting marked as spam, I've discovered that you have to be patient when calling Customer Assurance. I had to call a few times before I got to a rep who understood the problem and was willing to work with me.
In the alternative, I've also discovered postermaster.comcast.net. If your mail is blocked by Comcast with an error code of code BL000000, you can submit a form here to have the block lifted.
