Not sure if you want to keep this IO.inspect uncommented

For now I'm happy to leave these kinds of logs in this App.
When we are paying for the storage of logs, we will have to be strict about them
and will probably have a pre-commit hook/check to not allow uncommented IO.inspect. 👍

@SimonLab yeah, Lambda functions also go to "sleep" after a period of inactivity to save RAM on the VM running the function. The function gets re-loaded into RAM "just-in-time" for a fresh execution but it stays "warm" for between 5 and 45 mins after that depending on the scheduler (i.e. how many people are using Lambda in your region) but that is all "black box" to the developer. We tested it extensively at TC, that's how I know about it. |

It does not "block" the UI in the Auth App it just makes the request for the "pixel" in the background.
The point is to "Wake" the https://dwylmail.herokuapp.com App so that after successfully authenticating with the Auth app, the email is sent as fast as possible. If you open the Email dashboard in a different tab you'll notice that it loads instantly:
Obviously this is a stop gap until we deploy all our apps to VPS: dwyl/learn-devops#59
