This is literally the greatest service I have come across. Honestly, it was like a godsend, all day I was studying on all these little details required to having a solid, protected, non-blacklisted, works on ec2, stable, spam-free, e-mail server.

After hours of configuring postfix and looking at files I never wanted to even know about I took a break on HN.

Then I saw Mailgun, boom.. problem solved. (With more bells and whistles then I even imagined)

I've now saved part of my life thanks to this product.

Even chatted with one of their dev's who is extremely helpful. This is the kind of company I would want to invest in.
