I haven't tested push notifications as much as probably most users here have (We've spent around mid 5 figures over the past couple of months across multiple networks).
That makes me no expert, but I feel like it gives me a good idea of what to expect from this type of traffic
So due to the "meta" hype i've recently signed up to megapush...
Based on my brief experience with megapush, i've been quite honestly disappointed
- High volume of fraudulent traffic
- No ability to keep track of impressions delivered
- limited capabilities to optimize "feeds"
So I guess my question is, what is the hype about and what makes them beneficial compared to buying directly from the sources they re-broker from?
Hoping you can help a push n00b out here, thanks in advance 
Hey daanja, think of Megapush as a marketplace for push traffic. They buy from All of the push networks around (Us too, if you bought from us and liked the traffic we have feel free buying directly from us), so you can really test everybody and see what network works best for you. They have their own users and they buy push traffic, not users, from networks.
Each network in the mix has a different mix of traffic so you get different results. We work with direct traffic almost exclusively, so that's kind of our thing
Hope this was helpfull 
You could say the same about any traffic network that resells traffic from others, actually about all traffic networks in general, since none of them really owns the traffic ... They all work with publishers, that you could buy from directly, in theory.
When working with a particular network, it all comes down to whether they are able to offer you something, that the publisher (or other network) can't.
It's easy to see why you'd choose a network over the particular publishers ... more volume, targeting options are the most obvious. A site owner is not likely to sell you just iphone users from US, while pretty much any network will do that.
When comparing one network to another, it usually comes down to 4 things : overall volume, targeting options, approvals and bidding model.
Let's say network A resells traffic from networks B, C and D on top of their own publishers. You can go to all 4 networks and use each of them separately, but that would mean 4 times the work that comes with managing 4 campaigns instead of one. Networks B,C and D can be smaller with less staff, so approvals will take longer there. Which means it might be faster to simply got to A and be running faster. Network A might also offer targeting option than none of B.C or D offer.
The bidding model next, let's take
And lastly, networks who resell traffic from other ones, often pre-pay for the traffic and book certain %, so even though you go direct with the other ones, part of the traffic will not be available there, because it was already sold to the big resellers.
I'm not sure how much of this applies to megapush in particular, but you get the idea.
Yeah for me megapush just sends to much traffic from countries I'm not even targeting so I stopped using them.
They claimed the traffic came from people using a VPN but like 50% of the traffic was from other countries and I can't see half the people using a VPN.
