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!

New Customer Data in the FB dashboard is so helpful. They include a dashboard with tons of good info. The flows in Klaviyo capture lots of missed leads and they are delivering amazing results. Michael's a terrific person and super honest. Don't think twice, you will get back the value X1000.

Not only have we noticed improved performance on Meta and Klaviyo but the support is second to none. Amazing product and service!

Their team is very intelligent and helpful. Integration was simple and they also helped fix our attribution issues from Klaviyo and Facebook. Michael has been an asset to our company.

We onboarded our brand about 3 months ago and the results have been amazing. The support has been fantastic but the results speak for themselves. Highly recommend you give it a go for your Shopify store if you have Meta & Google Ads.

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

Absolutely amazing. We tried several different (and expensive) solutions, but none of them worked, and several caused more problems than we started with. Upstack took care of everything. They gave us UNBELIEVABLE service, and walked us through getting all channels set up. Our event tracking is better now than it has ever been... and we are able to make much better marketing decisions because of it. We cannot thank Michael and the crew at Upstack enough... this app is HIGHLY RECOMMENDED!

Upstack 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!

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!

Michael has been a fantastic partner. 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 and generates a very solid ROI.

“We found this CAPI to better than others that we tried. Michael and team were excellent. We've had steady performance over that time and our scores in META are strong. I recommend.”

“I benefited from Upstack tremendously financially. I’m spending well into six figures a month and when you can get an edge on your competitors it’s a big deal.”

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

“Seamless onboarding. Positive results straight from the outset across Meta. Michael & team have been responsive.”

Moved from a competitor to Upstack. Very clear picture that Upstack 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. Incremental email revenue added a 41x ROI, not including the better data for ads.

"After testing out a number of platforms in this space, we onboarded with Upstack based on a strong recommendation. Klaviyo abandon flows are picking up significantly more revenue. This alone generates a very solid ROI on Upstack. Overall big thumbs up."

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

Upstack Data is great and setup was very straightforward. It has improved our data quality. Very Impressive!

We looked at several competitors and talked to some customers of Upstack and their competitors. From our research, they were by far the clear winner in terms of data accuracy, customer service and pricing. After installation, we saw improvements in our data and performance. This is a no-brainer and just about a requirement in today's privacy environment, especially for brands spending larger dollars on paid ads.

“The proof is in the email flows. Makes a big difference. Onboarding was easy and Michael personally walked us through everything. Way better than I expected, fantastic solution.”
