Subscribe to a mailgun backed mailing list via a web interface.

Build subgun using the build script:

./build

Configure subgun by setting a series of environment variables:

export SUBGUN_LISTEN=127.0.0.1:8080
export SUBGUN_LISTS=<mailgun list 1>,<mailgun list 2>,...
export SUBGUN_API_KEY=<mailgun api key>

Once configured, you can simply run the binary:

./subgun

POST to the subscribe URL. See subscribe.html or do it with curl:

curl http://localhost:8080/subscribe/[email protected] -d "[email protected]"

This will email [email protected] with a confirmation email with a URL that contains a secret token. Clicking on the link will change the subscription status to "Subscribed".

For now use the native workflow in Mailgun.
