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.

Amazing Amazing, how they do this service for free, I don´t understand! It has increased my website traffic by treble. I send a message to around 3000 members every day and each time is just like a traffic blast! Thank you to whoever created OneSignal and allow us to use your free service, you should be knighted!
