Common Gotchas

Mailgun recommends using a subdomain (e.g., mg.yourdomain.com) for sending, which keeps your root domain SPF record clean.
The include is mailgun.org, not mailgun.com. Using the wrong domain will not authorize Mailgun servers.
If you use a subdomain for Mailgun, the SPF record goes on that subdomain, not your root domain.
