Question - I need to create an automated retention push. Does your service provide such feature?
Autopushes is the feature that allows you to automatically trigger push notifications based on rules of segmentation. Segments are based on custom and default tag values your users subscribe to, and all you have to do is set up rules based on which Pushwoosh will periodically recalculate the target audience, and send a message to it. Basically, it allows you to automatically send push notifications to dynamic segments of your audience.
