Starting with Sytist version 1.1.0 is the Mailing List Feature. This allows you to collect email addresses from customers in a join mailing list form or during the checkout & create an account process.
This will ONLY collection email address for the mailing list. There is not an option to send out emails to mailing lists through Sytist.
WHY?
Because of SPAM it is hard enough to get emails sent from a server into an inbox. And if you were to try and send dozens, hundreds or thousands of emails out at a time, they most definitely will not get into inboxes and your hosting company would probably shut you off. Even if you have a dedicated server, the emails still would not make it into inboxes.
BUT ...
The mailing list feature is integrated with MailChimp which is an email marketing service. You can have up to 2,000 subscribers absolutely free! Email marketing services like MailChimp build relationships with the email providers to get the emails into the inboxes.
To get started with the Mailing List feature, go to People -> Mailing List in your Sytist admin. There you have the option to add a join mailing list at checkout & account creation, add a join mailing list popup, and information on adding it to a page or the footer.
Also connect the mailing list to MailChimp. Click here for an article on how to set up MailChimp into your Mailing List.
