It's nice to hear these case studies, especially this one, since Zawinski's law was one of the quotes we put on our whiteboard in the early days of Mailgun. It's also one of the reasons we focused so much on effectively parsing inbound email early on vs. just SMTP relay and deliverability stuff.

I was googling Zawinski's law because I was admittedly unsure of its exact origin and found this pretty good discussion http://programmers.stackexchange.com/questions/150254/what-d...

Post author here. I wrote up this simple tutorial because I was legitimately surprised how easy the basics are with Mailgun and wanted to show my appreciation.

I'm curious to hear how other people have tackled this problem and what gotchas they found along the way. The devil is in the details with this sort of thing.

@damoncali does the setup you describe work even if the user bcc's their special address? Will mailgun still give you the recipient as hard_to_guess74623@taskbox.kanban2go.com ?

It does. You can BCC your special address and the 'recipient' param is set properly.

thanks damon. looks like we're switching to mailgun :D

Great writeup and thanks for the intro to Zawinski's law!

I love the analytics that Mailgun is able to provide. We integrated the analytics into Mixpanel where we track all kinds of funnel metrics. Adding email boxes to apps is a necessity and Mailgun turned out to be a great solution for us. founder, kanban2go
