Opt-out management for abandoned cart notifications

[romainpoirier]

What are you trying to do?

I am looking to ensure compliance with GDPR regulations by allowing users to opt out of abandoned cart notifications. Currently, there is no built-in way for customers to manage their consent regarding these automated emails, which may lead to legal and user experience concerns.

What's your proposed solution?

I propose adding an opt-out mechanism that allows users to unsubscribe from abandoned cart emails directly from the notification itself. This could be implemented in several ways:

1. Unsubscribe Link: Add a unique unsubscribe link in the email, leading to a simple opt-out confirmation page.
2. Customer Preferences: Provide a way for logged-in users to manage their abandoned cart notification settings from their account.
3. Admin Controls: Allow store admins to see opt-out requests in the Craft CMS control panel and manually manage user preferences if needed.

Additional context

• This feature would help ensure compliance with GDPR and other privacy laws.
• It improves user experience by giving customers more control over the emails they receive.
• Similar features are standard in most email marketing and automation tools.

This is a great point and looks to be largely absent from this plugin since taking it over. I'll happy with including all those proposed changes!
