I think this app is doing ok...but I can't know for sure. Why? Inexplicably, the app does not append tracking parameters to their SMS...and if you add your own, then they automatically remove them before sending the SMS.

It also appears that the app takes "1 day view through conversion" credit for anyone who SEES their popup, regardless of whether they interacted with it... I sure hope that is not why they are hiding the analytics from me.

In any case, it's absurd to literally design features (i.e. stripping away UTM parameters) which will prevent users from tracking performance of the app...

To be clear, it's not that they remove my parameters and replace them with something else...I would be fine with that... Rather, they literally send traffic with zero UTM parameters (so they all show up as direct visitors) of their own, and they automatically remove any parameters that you add yourself.

It's all very suspicious, especially given the *INSANELY* generous attribution rules it makes for itself when reporting their own impact...

With all of this said, it appears to be a great app. Please stop hiding the data!

I was using a 3rd party marketing company and they installed postscript. It had some success but now I brought my marketing in-house and we're integrating this with Klaviyo. I love that Postscript and Klaviyo integrate together. I went into the app to remove someone from the list and chatted with Shannon who was extremely helpful and had a great attitude. Definitely recommend this app as we've had success in the past 4 months with Postscripts and have made sales using it. Now that we know it can integrate into Klaviyo I expect this to be even more successful.
