We use it in our organization to identify customers who want to unsubscribe from marketing emails or newsletters. It helps us save time by not having to manually look through each email after they've been sent out. The only thing I dislike about this software/tool is its price tag since we're still at testing phase of our implementation. But if you can afford it, then go ahead and try this tool because as long as there's no major bugs encountered yet, I'm sure it will be worth your investment. Customer Unsubscription. I love how easy it was to set up our account and get started! The user interface of this product has been very intuitive from day one. It's also free which makes it even better. There isn't anything I dislike about the software so far. We have used other products in the past but none were as simple or effective at what we needed them to do. This service does exactly what you need without being overly complicated.
