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!

Great developer, they think with you and with the great expertise our webshop is completely scaling proof again

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.

1. New Customer Data in the FB dashboard is so helpful 2. They included a dashboard with tons of good info like LTV number and such 3. Prices are very reasonable and Michael personally sets everything up for you, he built me flows in Klaviyo that capture lots of missed leads and they are delivering amazing results, he's a terrific person and super honest. Don't think twice, you will get back the value X1000.

This App is great - setup was very straightforward, all done on a shhort call with an expert based in the US - ongoing it has improved our data quality scores - one small issue which was fixed within an hour, very impressive!

Moved from a competitor to Upstackified and have a very clear picture that Upstackified is a faster setup, with a much more competent team, amazing customer service, and better performance, for a cheaper price- it's not even close. Just the incremental email revenue alone covered it's cost and added a 41x ROI, not including the better data for ads.

Implementation = a breeze. The data = clean. Integrations...tons! Overall super helpful to get us up & running and if we have any issues they are super responsive. Getting the data we need to scale campaigns & even helping our Klaviyo email instance to be more efficient. Thank you!

3rd party CAPI is important to increasing data accuracy with our marketing platforms. I looked at several providers and chose upstackified because I felt the technology and customer service were aligned with my business. After implementation our match rates went up over 30%. They even helped us navigate a few other technical issues along the way with a very personal touch. I highly recommend!

Excellent app. The onboarding from the founder Michael was great and he was happy to answer any questions I had. No false promises as well which is nice. Our match rate scores increased by around 20% from using the native Shopify integration. Highly recommended.

Seamless onboarding from UpStack team Appeared to get positive results straight from the outset across meta Michael & team have been responsive to queries on Slack Looking forward to seeing the results on our second store

After testing out and surveying a number of platforms in this space, we onboarded with UpStack based on a strong recommendation. It's been a few a months now and absolutely no regrets. Michael has been a fantastic partner. It's rare that I run into someone in ecomm that has a truly deep technical knowledge of the attribution space given that it's quite the black box. He knows the space forwards and backwards. Very impressed. He's readily available to assist and I've picked his brain many times, quite often on topics hardly related to his platform and he's yet to tell me to get lost. We've seen Event Quality Match scores in meta increase, adding reliable NC purchase, NC CPA and NC ROAS metrics in ad manager is massively helpful as we're very focused on optimizing for NC, Klaviyo abandon flows are picking up significantly more revenue outside of our standard abandon flows (this alone generates a very solid ROI on using UpStack). Overall big thumbs up for building a great platform and strong recommendation to others. With Michael's personal onboarding walk through which made the onboarding super simple and eliminated the chance of misconfiguration, combined with the trial period, there's no reason not to onboard to the platform and give it a try.

Support is next to none, extremely happy so far. Michael Alt has been an amazing partner to work with and is very honest. Just ask him any questions you have and if you are satisfied with the answers, DEFINITELY go for it!

Moved from a competitor to Upstackified and have a very clear picture that Upstackified is a faster setup, with a much more competent team, amazing customer service, and better performance, for a cheaper price- it's not even close.

We found this CAPI to better than others that we tried. We did have some initial challenges installing due to customizations on our end - but Michael and team were excellent in working through those issues and we have been live for several months. We've had steady performance over that time and our scores in META are strong. I recommend.

Upstack is a must-have tool for improving conversion rates and maximizing ROI. Highly recommended! Michael is an expert and wonderful to work with.

I've tested out a few apps to link up data. I found Upstackified the easiest and best data integration for facebook. I chose this over Omega pixel and elevar. I had a meeting with Michael and was impressed with the knowledge and willingness to help audit and ensure everything was setup correctly. I'm at the $250 a month level. Which is a fair price at the end spend level we are at.

Great alternative to elevar. Priced better and I think even more accurate. Plus Michael helped set everything up which was huge. Also, the NC ROAS inplatorm feature in Meta is awesome.

I've been using this app to track conversions, and I must say, it's been incredibly helpful in providing accurate measurements. The customer service team has also been outstanding; they've been prompt and effective in addressing any issues or questions I've had. Overall, I'm impressed with the app's functionality and the level of support provided. Highly recommend it!

I can't say enough good things about this app. I searched high and low for an attribution solution that was affordable and not overly complicated and this is it. Attribution can be so difficult and since implementing upstackified, ours has improved dramatically - esp. on the meta side of things. Without this level of attribution you are just wasting money on your ads. Michael was super helpful and responsive with getting us set up and answering any questions we have had. Perfect attribution may not be possible these days, but this seems darn close. Super happy with upstackified! A great value!
