Yes, you can use MailChimp for an affiliate program, but with limitations. MailChimp allows you to share affiliate links in your emails as long as the content follows their guidelines. You must avoid promoting spammy or misleading affiliate offers. MailChimp does not allow content that violates its terms of service, such as get-rich-quick schemes. You should focus on sharing valuable content alongside your affiliate links to build trust. MailChimp also restricts some affiliate networks, so check their policies before sending campaigns. If you follow the rules, MailChimp can be a good tool to promote affiliate programs and earn commissions.
