Expert from Spam Resource shares that compromised accounts or email spoofing where spammers send email that appears to originate from your domain but doesn't, can generate automated responses such as out-of-office replies or unsubscribe requests. Regularly audit email authentication and user permissions to prevent spoofing and protect against unauthorized access.

Expert from Word to the Wise explains that a sudden spike in unsubscriptions often comes from spambot or scraper activity. You can investigate the unsubscribes, looking for patterns.

The best approach is to block the offending IPs or user agents from accessing the unsubscribe links.
