Mailgunner here. That's actually not the reason we end of life's the product. It just wasn't very popular unfortunately. If it was, we probably would have keep it. This was actually what we thought would be one of the coolest features of mailgun, but it never took off. Sorry you won't be able to use it anymore. Obviously you were a happy user. I wish there had been more! Btw, Rackspace email is $2/box not $5. Any they have reseller plans that cut cost even more. Not free but still really cheap. Good luck with your search!
