Rianu is a CRM for developers and makers. It allows you to use a simple API to load subscribers.

With Rianu you can create an automated sequence that will send email responses with training or offers to your new users. We can send alerts to you or members of your team.

With the automation you can move subscribers from the Trial users list to the Trial over and send them an email to let them know their trial is over.

Rianu is designed from the ground up to be a help to those of us who build SAAS products.
