Mailchimp

Mailchimp has been the platform choice for newsletter publishers since 2001, evolving from a bare-bones tool into a full-featured marketing suite. The template library is extensive and responsive, and automation workflows let you send triggered emails based on subscriber behavior. The free tier supports up to 500 contacts with core features, making it a practical starting point for bootstrapped creators.

The platform appeals to newsletter creators who need straightforward, reliable sending alongside some audience segmentation. As you grow, paid tiers open up advanced segmentation and deeper analytics, though many solo creators stick with the free version indefinitely.
