For a solo user, the free plans of both Mailchimp and Substack offer basic functionalities but come with limitations. The Mailchimp Essentials Plan allows up to 2,000 subscribers and 10,000 emails per month, which might be insufficient for high-volume email campaigns. In contrast, Substack's free plan provides unlimited email newsletters without paid subscription or advanced analytics features.
