MailChimp is built for email marketing and as an ESP, we are required to enforce spam laws. This means you must include an unsubscribe link in your campaigns.
The unsubscribe warning is a “heads up” that some of your subscribers no longer wish to receive your campaigns. If you receive more than a handful of warnings, it’s a sign of larger issues that could start to affect the account standing.
