Etsy now keeps an active archive of past Etsy Finds newsletters on their site. For more recent newsletters please visit their site.
Every now and then, my Etsy shop would get a sudden burst of visitors, when I would check Etsy stats I found out it was coming from being featured in an Etsy Newsletter. I now keep all my Etsy Newsletters so I can look back, for the issue that had me in, but at the start it was a crazy search to find it.
I have been keeping the current archive since mid June 2013, and managed to find several copies from 2012 in addition to my personal copies. Do you know of an Etsy Finds newsletter that I do not have listed below? Then please send me an email and I can include it on the list.
