Nice but no support It's all good as long as you do not run into an issue. Support doesn't exist, they will just refer the documentation.

I've used OneSignal for 4 years for my… I've used OneSignal for 4 years for my business. It was easy to implement (took me less than 30 mins to setup) and I built a few automated messages for every new user and to re-engage existing users. It's incredible product for a great price. Thank you!

NEVER USE THEM ...SECURITY ZERO Never use their services, in case of hack of your Onesignal account, you will have no support and they don't have any kind of protection against a unkown ip or different logins and basically attackers goes to your account change password ,transfer applications without one email to owner and then start spamming your users with notifications while you can't do anything. in the end support doesn't exists . app gets completely ruined. while you can't do anything except watching. as i have seen i am not the only one who faced this . BE VERY CAREFUL.

Terrible custumer service -

Bad and expensive Precedent was unlimited free subscribers In the year of 2019, it became limited to 20,000 subscribers In 2020 it decreased to 10,000 subscribers In 2021, they increased the prices by 3 dollars for every 1000 joint payments Each time, they raise prices, even though their price is very exorbitant, nearly 6 times $ 100 every month on this paltry The best you do $ 100 on Facebook ad campaigns and get a lot of traffic
