In practice
People expect it at once and rely on it, so it needs the best delivery you have. Many senders keep it on a separate domain or IP from marketing so a campaign problem does not delay a reset.
Verification and sending
A wrong address means a customer never gets their receipt or reset. Verify addresses at signup and checkout.
