I have very frequent issues receiving and sending emails to my business partner (also using Comcast), and additionally our clients. We are experiencing the same problems that I have read from others in the forum. It has been happening for a few months and is greatly affecting our business since this is our major form of communication and also time sensitive emails are not being delivered. Emails will show as sent but are never received. Nothing is appearing in spam folders. It is random, out of multiple emails sent back and forth daily one or two will never show up. I've noticed you have been able to resolve this for other customers, I hope you will be able to do the same for us. Trying to be patient but please help!

I have been on the phone with Comcast and they opened a ticket in my name. After getting back to me they had me go into the setting's in the top right corner of my account page when in my inbox. They then had me click on "Advanced Settings" and then un-check the "Spam Filter" box. That had no result, people still are not receiving my e-mails. I then got on the line with them today and they had marked my "ticket as fixed" well not true. I have multiple e-mail addresses and none of them be it Gmail, outlook, etc receive my emails, sent from comcast.net. Weather on my wifi, ethernet, on the app on my phone, etc.... I have gotten them to open a serious ticket and escalated me to the "highest" level of ppl who work on "Just the e-mail" account issues, not anything else. They are supposed to call me back tomorrow at 5 pm MST. If this sounds familiar (ppl not getting your sent messages 95% of the time) but you still receive messages in your inbox let me know and I'll follow up with you in case they do get a resolution for me.
I actually work in computer systems myself and have a Bachelors's degree in computer science and this is an issue that has to be corrected on the back end. I went over all the troubleshooting steps with them and they agreed. If you have gotten any resolution please let me know. I'll check this feed tomorrow after I have spoken with them and share my results with all members of this chat. Thanks.
comcast.net is a residential email platform and you are likely to run into issues using the email platform for any purpose outside of it(work, business, charity, etc.). You are likely getting caught in the spam filter when sending out emails. Feel free to PM me the emails you are having issues with and i can look into it for you.
