SIPPERS review for ONE: AI, Email & SMS Marketing

Aug. 12, 2023

A really good app with countless functions. It was important to me that I have an app where the double opt-in procedure is guaranteed. ONE offers it in detail. You have numerous options for designing e-mails, SMS, pop-ups, etc. according to your preferences. It also looks very professional and good. Numerous templates are already available and 100% customizable. I would like to give 6 stars for customer support. I get direct help and my questions are always answered 100%. ONE is a great app that includes numerous functions and is also relatively cheap. I can recommend it!
