Mailgun + LoginRadius

Mailgun is an email service for developers.

Example Use Case

Implement the LoginRadius Identity Platform on your websites.
Collect customer profile data each time your customer registers or logs into your websites.
The LoginRadius Identity Platform will centralize your enterprise analytics from all of your websites and send this data directly to Mailgun. You can now easily manage all of your customers at one central location.
You use this list to send out automated welcome emails thanking new customers for signing up and providing further account setup instructions.
As a result, your cancellation rate is reduced and your customers have higher satisfaction rates.
