I've been following the development of Mailtrain for a few weeks now and I couldn't be more excited for this project. It's super fast, the interface is great and it took about 4 minutes to install locally.

I'm on Sendy right now which has zero segmentation and development seems to have really slowed on much-needed features.

If you do any sort of email sending, this will save you hundreds per month. I've backed the Indie GoGo and I encourage everyone else to do this as well.
