"Very easy to use and intuitive"
— Alexander Koper What They Say

How can we add a mailing list subscription form?

Mailing list integration is something that can be provided by a plugin. Try searching for mailing list, newsletter, MailChimp, AWeber, Constant Contact (and other services) in the plugin directory.

On a related note, you may also want to learn about the integration between the Event Calendar Newsletter plugin and our Church Content plugin. It makes sharing about events with your mailing list audience easier.
