I’ve been using Upstack for about two weeks and the experience has been extremely frustrating. First of all, support is basically non-existent. I’ve contacted Michael multiple times regarding dozens of warnings showing up in Events Manager, and he simply does not respond. When he does reply (rarely), it’s clear he hasn’t read my messages carefully and ignores the screenshots I provide. Second, the tracking quality is seriously flawed. For example, around 55% of my PageView events are sending the same IP address instead of unique IPs per user. This completely breaks data accuracy, attribution, and audience building — which defeats the whole purpose of using a tool like this. On top of that, there are multiple warnings (invalid timestamps, data inconsistencies, etc.) that remain unresolved even after reporting them. And finally, the pricing is absurd for what it delivers. It’s extremely expensive, and honestly, even if it were free, I wouldn’t use it in its current state. Overall: poor product, poor support, and unreliable tracking. Not recommended.

Not only have we noticed improved performance on Meta and Klaviyo but the support is second to none. Any issues we've had Michael has arranged a call immediately to diagnose the issue. Amazing product and service!

This app has been incredibly helpful in navigating Meta’s new health policy changes. It provided an effective solution for fixing custom event tracking, ensuring our campaigns remain compliant and still track. Highly recommend it for anyone facing similar challenges!

This App is great and their team is very intelligent and helpful. Integration was simple and they also helped fix our attribution issues from Klaviyo and Facebook. Michael, specifically, from Upstackified has been an asset to our company.
