Igaming ads join tg channel high cost t3

So I’ve been running ads for client in the igaming niche in the t3 geo

We had 0.5$ cost per telegram prediction channel joins and when we scaled the spending we had 6$ cost per join

That’s wild, I’m only using Instagram ads with client videos talking about the niche

Looking for new ways maybe purchase email list from the target country

Can you help me with advice?

What you’re seeing is pretty common once you scale, your initial “cheap pockets” of traffic get saturated and Meta starts expanding delivery to colder audiences, which pushes CPA up.
