When a Stripe checkout session expires without payment, if the customer
entered their email, we record an AbandonedCart and schedule a single
plain-text recovery email (1h delay via Oban).
Privacy design:
- feature is off by default; shop owner opts in via admin settings
- only contacts customers who entered their email at Stripe checkout
- single email, never more (emailed_at timestamp gate)
- suppression list blocks repeat contact; one-click unsubscribe via
signed token (/unsubscribe/:token)
- records pruned after 30 days (nightly Oban cron)
- no tracking pixels, no redirected links, no HTML
Legal notes:
- custom_text added to Stripe session footer when recovery is on
- UK PECR soft opt-in; EU legitimate interests both satisfied by this design
