Postscript SMS Marketing

My retail shop uses a welcome series coupon code for our new customers. We've been having trouble recently with the same subscriber being able to access a coupon code each time jumping onto our site. Not a huge deal but we want it to be special for our first time guests. Today I finally jumped onto a chat with a postscript guru. Michael is our saving grace! He quickly and efficiently helped to solve our problem we had been dealing with for a couple of months. HE IS CRUSHING IT! Extremely kind and helpful. Thanks again, Michael!
