Transactional email in Ghost can be configured to send with any SMTP, or another mail service that you prefer, using Ghost’s standard configuration setup. Bulk email delivery for newsletters is a feature which requires a bulk mail API. Currently the only bulk mail API we support is Mailgun. If you don’t want to deliver posts to members by email, you do not need a Mailgun account and you can safely ignore the email newsletter settings completely.
Why do I have to set up Mailgun?
Ghost has the ability to deliver posts as email newsletters natively. A bulk-mail provider is required to use this feature and SMTP cannot be used.
