SHORT ANSWER
Design a useful, consent-based recovery flow that stops when the customer buys or opts out.
Define a real abandoned cart
Allow enough time for the customer to decide. Timing should reflect the product and buying cycle.
Send a useful message
Identify the store, explain why you are writing, offer help and provide a clear way to return or opt out.
Stop at the right moment
End the recovery flow immediately after purchase, refusal or opt-out. Escalate real questions to a person when needed.
