When I decided to launch advertising via push notifications, I faced the question where to buy push notification traffic ? There are a lot of options on the Internet, but some are too expensive, others are questionable. I was lucky that I came across article. It clearly describes which sites to choose, how to check the quality of traffic and what to pay attention to. Thanks to this, I was able to choose a normal source and not waste my budget. If anyone is in the same situation, I advise you to read it.
