I can't answer a message from a customer. The I am about to send the answer It appears a red sign saying that my username is not a valid Etsy name. But I can't change my username as well. What can I do?
If the message was about a sale, but the buyer needed your email, their username is no longer valid because they were removed for scamming.

The user account has been deleted - probably a scammer. Just ignore it.
Thanks a lot
