I've got a really weird thing going on.
Some mails that I regularly get (newsletters etc) are suddenly coming into my inbox as plain text emails. I have emailed them and they say no, you are on the database to receive html emails. They've always been html emails before, just for a week or so they suddenly are plain text.
It's not affecting all html emails, just some. And from different providers. I think it's really weird.
Any ideas?
