No, you don't need your own Mailgun account when using Magic Pages. Let me explain how email delivery works with Magic Pages' managed Ghost CMS hosting service.
How Email Works on Magic Pages
Magic Pages provides fully managed Ghost hosting, which includes complete email infrastructure for newsletters and member communications. This means that all email sending is handled through Magic Pages.
Your newsletters and transactional emails are managed automatically, without having to set up and pay for a separate Mailgun account. Your plan always includes a specific number of emails per month (with additional emails available at $5 per 10,000).
What If I Already Have a Mailgun Account?
If you're migrating from a self-hosted Ghost installation where you used your own Mailgun account, you should be aware that you cannot connect your existing Mailgun account to Magic Pages, and that your previous Mailgun settings won't transfer over to your Magic Pages site.
This approach allows me to ensure reliable email delivery and properly manage all technical aspects of email sending that are critical for good deliverability.
