Reading this got me thinking about using mailgun for my nodejs app. I noticed that the article didnt use off the shelf mailgun 'client'. Is it because the available mailgun npms are old/bad or just to showcase how "easy" it is to write your own?
It shows how easy it easy to write your own function because all you need to do to send an email is perform a single HTTP request.
My favorite about this is the "testmode" flag which removes the need to mock your tests when sending emails.
