According to legal documentation (GDPR, CAN-SPAM) and email platform guidelines (Mailchimp, Sendinblue), reactivating old unsubscribes is not a recommended or compliant practice. GDPR requires explicit and freely given consent, while CAN-SPAM mandates honoring unsubscribe requests. Email platforms actively discourage reactivating unsubscribes, promoting best practices like double opt-in and list segmentation instead.
