substack emails blocked

@rockiestone I'm going to DM you to get some details specific to your issue, I can see substack emails being delivered successfully on the platform, we just need to figure out what you are having an issue.  Thank you

Hello and Good Morning, @rockiestone Thank you for reaching out to Xfinity Support on the Community Forum. Did you get the email issue figured out, or did you need further assistance?

I am sorry to read that, @rockiestone I will be happy to work on it with you. Is sounds like a business account, correct? I assume that you have tried all the basic troubleshooting, correct? Filters, forwarding, and spam settings?

Yes.  I wondered why my e-mails from Kyle Westaway, Heather Cox Richardson, and Dan Rather suddenly disappeared.  Very annoying.

In a word, censorship. 

@rockiestone Do you have samples of the senders you're missing out on?  Do you happen to remember when they started failing to show up?

It's far more likely that the messages were accidentally reported as spam by the user or their client, and resulted in a report being sent back to Substack.  The ESP (in this case, the ESP is Sinch/Mailgun) sending on behalf of Substack then add the recipient to a suppression list to prevent further complaints.  If you'd like to DM me the email address which should be getting these messages, I can try to ask the ESP (which maintains the suppression list) if they can look into it.

Substacks from these sites are not received.  The senders did not block them, but xfinnity did as I often found them in the spam folder and would click on "not spam"  I am going to try creating a non-comcast address in iCloud to get the messages via Apple rather than Comcast.  Fingers crossed that will work.  I think your spam policies need to have a tuneup.

Kyle Westaway, Heather Cox Richardson, and Dan Rather... forgot to post this in previous message.

@user_c70501 There's a difference between "blocking" and placing a message in the spam folder.  For the spam folder, you can add the sender's email address to your Address Book in the Webmail interface to override the situation where may believe a message to be spam.  There are some email clients that have their own spam filtering, which could be a possible cause.

It is highly unlikely that we would outright block messages from Substack.  Spam foldering is also an extremely low percentage of Substack messages.

Without your email address to do more research (and it should be a recently observed issue), there's not many more questions I can answer. Feel free to DM me your address, and I'll see what I can discover.

Thanks, not sure how to DM you, but my address is [Edited: "Personal Information"]

Also, it just seems very odd that all messages from 3 different senders disappeared at the same time.  Seems illogical that all 3 would implement new spam filtering at the same time.

I have no more time or energy to pursue this. The substacks stopped on the same day and were never in my spam folder. That is all I can say. My last note with this message seems to have disappeared.
