Trying to reply to a message, it says can't be sent and to contact support. What the heck is going on?
You may be trying to reply to a scammer. In this case Etsy will block the message.
The other possibility is that Etsy has blocked your messages for spamming potential customers - people who haven't contacted you first.
Will my star seller take a hit for not responding?
@BodaciousBottles - Mark the message you are trying to reply to as "spam".
