How can I opt in a customer for marketing emails?

If a contact is not opted in for email marketing, and they wish to be, you can add them a couple of different ways. From your site, where you collect emails, or from within Shopify.

There are two methods available for individuals to subscribe to your email marketing.

• Via your store website 
  • Enter email in Subscribe to our emails
• Within your Shopify dashboard
  • Go to Customers tab
  • Click on customer name
  • Click three dots in Customer section
  • Edit Marketing Settings
  • Check Customer agreed to receive marketing emails.
