Hey Dana,
So I tried this idea, and messaged quite a few members that have followed me, and guess the bummer.. I got a message from Etsy saying that this kind of emailing is considered spam, good intentions or not, and so I guess a member complained that I had sent them a Thank you for being an etsy friend, and as a thank you we want to offer you 10% off.
I didn't think that was something wrong, but I guess it can be seen that way. Just thought you guys would want to know before you get an email like that from etsy.
Bummer, good thought tho!!
