If you are running a WooCommerce store I can not recommend Metorik with the Engage add on enough, not an affiliate I’m a everyday user.
From one of the Founders:
Over my time at Automattic, I suggested we pursue it as a company and team but again, there wasn’t any interest. Regardless, my passion and drive to solve the problems that today Metorik solves never waivered, and I was determined to build the product I always wanted even if it meant giving up an incredible job and lifestyle to start from scratch and hope for the best.
