Double opt-in

It costs some signups, because not everyone clicks. In return you know each address is real and controlled by the person, and you hold a record of the confirmation.

It catches typos and made-up addresses that a verifier would also flag, and it proves ownership, which verification cannot. Many teams verify at capture and confirm after.
