When the subscription feature was still under Labs in the Ghost admin UI (v4 I believe), it allowed me to configure Mailgun there. But now I don’t see any place to set up Mailgun in the admin UI (in v5).
Is it only possible to configure Mailgun with the config.production.json file? I don’t have access to that (or any raw files), just the admin UI, as I’m using a Ghost SaaS (digitalpress.blog).
