Thought this was worth posting: $1-3 CPMs from 19.5k active USA subs
That's fantastic! Mind you, building up a US subscribers list requires a big upfront cost as this type of traffic is very expensive. But if you can afford it, it clearly can be very beneficial, as in this case.
I, too, have been playing around with building various subscribers lists. Although my CPMs are nothing like yours, it does show how valuable US subs are compared to others. For example, in December I built a list of around 10k subs using worldwide traffic - big mistake, camp was difficult to optimise and revenue was very low! Here's what I was getting for India and Indonesia, for example:
So, for 4,332 IN subs I acquired $7.19 from 857k pushes, and for 1,944 ID subs I acquired $3.68 for 364k pushes. And this is for the period 2 December to 19 December 2019, during which time I acquired close to 10k subs in total from many countries. The list is still bringing in some revenue (less than $1/day) even though the number of active subs is now less than 3k.
Fast forward to the present day:
So I started another campaign on 11 January to collect US subs. I have only collected 254 so far, but what a difference! CPM up to $0.0609 (compared with laughable $0.0002 for IN and ID above) - a 300x increase! Now, $2.45 total revenue for 3+ days is not a lot, but it has been achieved with only 254 subs and only 7k pushes, and it is increasing daily:
Gone up by $0.10 in the time it's taken me to write this post!
