I was working for a start up some years ago where we were sending a lot of transactional messages over email, sms and mobile push to our customers. There were lots of great solutions around that solved the infrastructure problem (i.e, the problem of sending and email, sms or mobile push) but nothing that helped us with the content part of the message, rather then having transactional email templates in Mailchimp or something. So I built Postways [1]. In a nutshell, it's basically a message management system with a unified API for sending email, sms and mobile push were you have to bring your own AWS account or SMTP server.
