To add email preferences for customers, you can:
- Create a Preferences Page: Add a page to your site where customers can select their email preferences.
- Store Preferences: Use a form to capture these preferences and store them in your customer database.
- Update Profiles: Ensure the form updates the customer profiles with their chosen preferences.
- Segment Emails: Use the stored preferences to segment and send targeted emails.
You might use tools like Mailchimp, Klaviyo, or a custom solution based on your site’s platform.
