I received the same email and it also seemed suspicious to me. I just sent an email to Fab support asking the same question. I recommend NOT clicking on the link that appears in the email. When you hover over the link, you can see that the link it directs you to also has a suspicious address (attached screenshot)
Received 3 same mails in a row. A seller’s email address should only be disclosed to buyers who have successfully completed a transaction with that seller. Buyers without confirmed purchase history with the seller must be denied access to this sensitive information.
