Upstack Data ‑ Tracking Pixel

They're a great CAPI integration on Meta and work extremely well with Klaviyo and Google as well.

Beyond just the tech, they've been a great partner. They get back to me when I'm panicked about ad performance and dig into the pixel setup. They help me diagnose, guide me on future implementations, and are, altogether, a very reliable partner for a service that absolutely cannot slip.

The dashboard is easy to use, but ultimately, the key thing I need is a reliable partner where I know my data is solid and they've been that for me.

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.

*** Update for : Their public reply is false.****

I first reported the issue on March 17, and even by March 22 I still had not received any real response or proper technical assistance, despite repeatedly asking for help during that entire period. In practice, I was talking to myself because nobody was actually addressing the issue.

The claim that they were responsive or actively trying to resolve this is simply untrue. I have the full conversation history, and it clearly shows how unprofessional, dismissive, and ineffective their support actually was.

Instead of taking responsibility for the technical problems and lack of support, they chose to post a misleading public reply and portray the customer as the problem. That says everything about how this company operates.

If anything, their response only further confirms my original review and strengthens my belief that this app does not deserve to be listed on Shopify in its current state.

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!
