TalkTalk Support will return to assist Community members from Tuesday next week. There's no TalkTalk Support for Community this Bank Holiday weekend.
The originators of the weekly mailshot are probably using Amazon's Simple Email Service (Amazon SES) to send out their mail. That mail service does utilise an email suppression listing to stop sending mail when there's a repetitive fail to get mail delivered to any recipient. So, if there happened to be a delivery issue then your email address would get added to the suppression list and you'd get no more mail messages.
Ask the customer service team for the originator to check and remove your email address from the sender's suppression list and then you'll get their mail messages once more.
Let us know the outcome.
