Why it matters
A Mailgun private API key can send mail and read logs for your Mailgun domains. A leak enables spam and phishing from your domain and exposes recipient data in logs. It is a long-lived secret.

Move the key into an environment variable and read it at runtime. Rotate the private API key in the Mailgun dashboard after removing it. Keep it off any client-side code.
