The tool is pretty easy to integrate and helps to re engage lot of our subscribers. The support team is very responsive and patient in answering queries.
Very easy to configure, Free and with a excellent technical support.
The good thing about Truepush is that it's completely free and the number of subscribers is unlimited.
The biggest problem I've had is audience retention. There was always a problem with the old provider where subscribers would just fall off for the most benign reasons.
Never have I faced that problem with Truepush.
API is not good, it has very limited features. There is no way to send a notification to test users.
