Hey everybody, I am currently helping my client setup a SMS gateway in order to reach out to users, but SMS gateway is expensive in terms of big volume. As such, do you know of any product or cloud services out that can Send out messages using social messaging app such as Whatsapp, Facebook messenger, Viber, Wechat, Line, etc?
Or any cool alternative to SMS gateway?
Thanks!
