Hi @ParthaSarathy  , Thanks for quick response , what if we don't  have coupons package installed in current system , do we have any other way for it without using coupons package.

We have 1 flat file that contains 100 unique coupons(no other column in file) and we want to send these 100 unique coupons to 100 random recipients( from recipient table) using available activities in Adobe campaign classic V7(not by JS)
