E-mail from pimoroni@discoursemail.com going to my Spam folder?

Anybody else having issues with Forum e-mails going to Spam? No matter what I do they all go to my Spam folder. I’ve added discoursemail to my safe senders list. Marked them as “Not Spam”. Doesn’t help. Spent an hour or so on the phone with my ISP and they say its not a problem at their end. Its an issue with the sender.

Anyway, I’m just wondering if anybody else is also having issues?
