Emails not being delivered to comcast.net addresses (Newsletter/bulletin)

 I help manage the newsletter/bulletin at our local Elks Lodge. We send it out via email using Sender.net, and all SPIF and DMARC settings seem to be OK. Of the 1000 members we email, for the past few months, ALL the Comcast.net subscribers have not seen their bulletins. We have had them checking SPAM and other folders, and it seems they are just going to a blackhole. I tried an individual email from our sending account ([Edited: "Personal Information"], and the user didn't even see those. Is there some way to unblock our email address/domain so our members can continue to get their communications?

Domain is hillsboroelks.org

Hello, @user_s90qfq thank you for reaching out over Xfinity Forums. With you being new to the forums, I understand if you're not familiar with how the process works.

Please be mindful that sending unsolicited Direct Messages to an Official Employee of the Xfinity Community Forum is a violation of Forum Guidelines. In the future we ask that you please find the most appropriate public board for your question type and post it there. If needed, we may invite you to send us a Direct Message.

I definitely understand the concern of the emails not being delivered, and if you weren't aware if you are sending emails to more than 100 receipents at a time these can be flagged as spam/junk and not delivered based on our security settings. 

This website is great to view more information about emails, and if you still need assistance you can select the "Postmaster" tab to report an issue: https://spa.xfinity.com/help

Oh, my apologies. In researching the issue, the most common solution requested a DM. If that is out of bounds, I do apologize. I initially started this conversation is in the forum for email, right? Can we just work here?

At this point, I cannot send single emails to comcast subscribers, let alone the bulletin emails. They aren't even going to SPAM folders. Adding the email address to the address book doesn't change anything. How do I get the email address off the block list? We aren't a marketing firm nor a spammer, but rather trying to get information to users that requested it.

Thanks for any help you can offer.  

Matt

@user_s90qfq No need to apologize, we just want to ensure your profile isn't negatively affected in the future for violations. I appreciate the follow-up and the update that even single emails aren't being delivered. 

I'd recommend reporting the issue here: https://spa.xfinity.com/report

I tried the postmaster route, but it says the IP is not blocked. I just checked, and in the basic settings of that email address, it had a reply-to set that was different from the sending account. Remove that, and I think we are back in business. Thanks again.

I spoke too soon! The email message I sent, which is just links to the bulletin to download and some upcoming events, is not being delivered still. It is being marked as SPAM somewhere, It's just a basic HTML or even plain text email, but I get an instant rejection. In testing directly from the email box directly on interserver, I can send regular emails, but when I forward the newsletter (either HTML or Text), it just instantly fails and is marked SPAM. The reporting function seems to lock in on the IP, but I don't think that is where my problem lies. It says it is not blocked. 

I have also logged a case with Interserver, but trying to figure out where it is being marked SPAM on the Comcast side! Thanks,

Matt
