All Ghost(Pro) sites are configured to deliver newsletters in bulk using ghost.io as the verified sending domain, which is optimised for the best possible deliverability rates.
For customers with an established sender reputation, sending more than 50,000 emails per month, we offer the ability to configure a custom sending domain for newsletters sent from your publication. This is useful if your organization requires a DMARC policy to be configured with the domain activated on your Ghost(Pro) site.
Requirements
Custom sending domain support is only available on the Ghost(Pro) Business plan, and is a $50/month addon. Use of a custom sending domain also requires that you maintain additional DNS records for maximum deliverability rates.
This addon is only recommended for teams who are comfortable with advanced email configuration and are willing to put in the time and resources needed to maintain it.
If you’d like to use a custom sending domain with your publication, contact support@ghost.org.
