Matt Elms @MattElms We did see an uplift when we onboarded with @upstackdata, yes. Our EMQ scores improved by circa 20%.
Marcin @mar_szychowski I also wanted to share that @upstackdata has greatly helped my client. Previously, they only saw 50% of their sales on Meta, but now it's around 80%. I believe it significantly improved their results.
Mitch Sanders @mitch_scg Favorite software tool rn - upstackdata.com. Very quickly improved Lark Meta event matching. Easy setup for non-technical people like me, @michael_upstack helped clean up all of the poor setup I had previously done with other tools, and pricing is solid.
Trayan Hristov @THristov_ One of the biggest unlocks this year has been trusting @michael_upstack and using @upstackdata. There are Elevar, Black Crow, Little data, Triple whale and a bunch of others CAPI providers but so far we've added it to close to 20 accounts.
Signal hygiene
Upstack screens traffic before delivery, so platforms learn from real customer actions, not bots, fraud patterns, junk referrers or duplicates.
| Bad signal | Sent to your pixels |
|---|---|
| Bot traffic | Verified human actions |
| Fraud patterns | Eligible-market demand |
| Junk referrers | Trusted source traffic |
| Duplicate orders | One order, one conversion |
| Noisy event stream | Clean events sent to pixels |
Marketing optimization
Give ad platforms more complete conversion data so they can find more buyers as you increase budget, without CPA rising at the same rate.
Six-month change
Ad spend vs. CPA
Scaled ad spend 85% over 6 months while CPA only increased 4% Why Upstack
01
Capture, identity resolution, delivery and monitoring in one platform.
02
People who know your setup, not a rotating ticket queue.
03
No added connector fees, whichever platforms you send to.
04
No theme edits, no developer time, and most brands are live in under 20 minutes.
Results
Return on Upstack's own cost, alongside $92K/mo in recovered flow revenue.

Blended net ROAS up in 60 days, with CAC down 20% over the same window.
Reviews
Little exercise.
Maybe it’s nothing.
go open your events manager..post your results below.
In my opinion, conversion API is crucial.
When performance goes down i look at this.
If you’re struggling on Meta I would definitely look into your EMQ scores.
I use Mike’s company Upstack.
we are always in the 9s
I know it might not seem like a big difference but I’ve seen people with EMQ scores in the eights struggle… then switch to Upstack and dominate.
i have personally used 4 separate CAPI products imo his is the best.
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!
Upstack is generating an extra $3K/month in revenue we were leaving on the table.
According to our email guy (@JamesBoostBerry ), It's finding 20,000 additional add-to-cart events monthly that would have disappeared without follow-up.
We initially thought it was a tracking error, but confirmed these are real potential customers who wouldn't have received abandon cart emails through normal flows.
If you're not optimizing your cart abandonment strategy, you're literally watching money walk away...
Thank you @michael_upstack
