Myth: Double opt-in completely prevents list quality issues. True or False?

False. Double opt in significantly reduces but does not completely prevent list quality issues. It confirms address ownership and intentional subscription but cannot guarantee long term engagement or prevent all problems.

Subscribers confirmed through double opt in can still become inactive, change addresses, or lose interest over time. Consent ages. Circumstances change.

Double opt in provides the strongest subscription foundation but requires ongoing list management: engagement monitoring, sunset policies, and continuous hygiene. Initial consent does not eliminate ongoing maintenance needs.
