Email marketing
From Shopify Wiki
Shopify gives you the option of asking your customers if they wish to subscribe to Email Marketing.
The Options for this can be set in your Preferences / Checkout & Payment area of your Admin.
Log in to your Admin, go to Preferences > Checkout & Payment > Scroll to the bottom of the page and look for the "Collect Information for Email Marketing" section.
The Options are as follows:
- Customer agrees by default
- Customer disagrees by default
- Option is disabled and hidden
