Magic Pages' Ghost CMS hosting comes with native email newsletter functionality. An email newsletter is an extremely powerful tool for content creators and businesses alike. It lets you connect with your audience, grown an email list, and distribute your content effectively to the people who really care about it.
On the Magic Pages Starter plan you can send up to 2,000 emails every month, on the Pro plan even up to 10,000 emails every month. If you're still on the free trial, you can send up to 100 emails.
