I've been facing a frustrating issue where I'm not receiving emails from three specific companies: Capital One (UK), Deliveroo, and the Department for Work and Pensions (DWP)/Universal Credit. Capital One even acknowledges the problem by sending letters explaining that they can't send emails to me. I have updated my email with Deliveroo multiple times, but I still stop receiving their emails after a while. As for the DWP, I haven't received anything in years, which means I occasionally miss important updates unless I log in to check my account.
I've been using a personal domain registered with A Small Orange and Google Workspace for about 20 years, and I never faced issues like this until recently. It's peculiar that it only seems to affect these three organizations. Any insight into what might be causing this would be greatly appreciated!

Have you considered adding those domains to your whitelist? Also, check if there are any MX records besides Google's for your domain. It might help to look into your domain’s reputation too.
It seems like your email server could be blocking those messages, possibly thinking they're spam. If Capital One is aware that you're not receiving their emails, they might be bouncing back. You should definitely ask them for the bounce message—it usually contains useful details on what's going wrong. Also, have your email service provider check their logs to see if they received those emails.
If Capital One is notifying you about the delivery failure, that typically means their emails are bouncing back to them. You might have better luck getting logs and details from Google regarding your email forwarding than from those companies.
