subgun

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

Build and Configuration

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

Subscription Workflow

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

curl http://localhost:8080/subscribe/etcd-dev@lists.coreos.com -d "email=brandon@example.com"

This will email brandon@example.com with a confirmation email with a URL that contains a secret token. Clicking on the link will change the subscription status to "Subscribed".

Unsubscribe Workflow

For now use the native workflow in Mailgun.

What about archives?

TODO

• Already subscribed user error message instead of user error
• Cleanup HTTP handling
