Unfortunately, we do not currently offer a newsletter service. We do hope to introduce something in the future, but we do not currently have a firm date as to when this will be launched.
At the moment, Create does include a newsletter sign up form that is located in the footer of your website. Through the use of this, you will be notified by email, the visitor's email address so you can make a record of these and use this information to create a mailing list to use with another service, such as MailChimp.
You can enable or disable the Newsletter sign up box by clicking "Content" on the top menu in your Create account and then "Site Footer" in the left-hand menu.
For more information about your website footer and selecting what content appears within it, please see this help guide.
Once you have collected your visitor information you could use a system such a MailChimp to send out your newsletter.
If you decide to use MailChimp you will first need to set up an account here. Once you have registered an account you will then need to set up a "List" with all of your contacts, which you can read more about here.
When your list is fully populated you can create a campaign, which is effectively a newsletter that you can send out to the customers on your list. For more information about this please read the guide here.
