Was the email from the exact same firstname.lastname@example.org address as before?
I'm really not impressed with them if it is.
I don't blame you for being confused, monbron.
At this point I'm confused too.
I've been trying to search Google to find out if the zendesk email could be legit, and finding nothing definitive.
When I go tohttps://www.malwarebytes.com/privacy/
they list zendesk as one of several "Analytics and marketing services" they use.
But it doesn't indicate they're using zendesk.com as a support email.
