On a recent campaign it looks like all our subscribers with a Comcast email (around 60) had our email block and marked as "Mail Block - Spam Detected". I believe it's the first time this happened where an ISP has blocked our entire campaign.
Has anyone else experienced this or might know whats going on?
It does look like Comcast blocked some of our email last night (Sydney time). We've contacted them and they have removed all blocks so emails are now flowing through as expected.
Thanks for the update Mathew!
Since it's a "soft bounce" will it try and send the emails through again and hopefully getting through this time?
It sure will, provided this wasn't the third soft bounce in a row for this subscriber. If that was the case, we'd consider it a hard bounce and move them from the Active to Bounced category of your list.
I had the same problem today. I know Comcast is know by telling you they will whitelist you but doing nothing at the end.
If there a way to get past them - they really don't care how much authorization you have to send the emails nor how much the recipient wants to receive it - they just block you.
We've been in touch with Comcast about some blocking today and they have told us it is being sorted out - we are seeing emails go through to Comcast fine now so all appears to be working. We appreciate this is frustrating, it's an unfortunate part of email.
Hi guys, we have a client that we send on behalf of... and after starting using their service we are know "blacklisted" by comcast. And not just for email newsletters that we send, but rather ALL emails that even their employees send using the same domain name in the email address. Has any of this been resolved?
There was only a very brief listing (as you can see, it was a year ago now) so any problems you are seeing now are not at all related to that.
It sounds like your client needs to work directly with comcast if all their emails are being blocked, as those obviously are not sent from our servers. From our side, I can confirm we are not seeing any problems delivering to Comcast at the moment.
Hi, kind CM folks!
All of the comcast.net subscribers to one of my lists just bounced; can you follow up with Comcast to get us unblocked? Some subscribers have been receiving (and opening) our newsletter for over a year.
Could you send an email in to support with the details about the specific campaign? We aren't seeing any blocks with Comcast right now so those bounces may be specific to your campaign content. We'll need to take a look at the specific bounce messages to see.
Hi . . . I see there have been issues in the past with Comcast soft bouncing campaigns as spam. Just wanted to alert you this happened to me today, with 35 subscribers not receiving the campaign. This is the first time I've seen such a high bounce rate from them. Anything you can do to help? Many thanks!
Hi there somaticpractice, please contact our team with client and campaign details and we'll happily look into why this happened and what we can do about it. Sorry for the hassle!
Thanks! I have sent a note and await response.
Thanks for your email - it looks like Tash on our team has been in touch. If there's anything we can help follow up on here, don't hesitate to let us know :)
