Beehiiv

Beehiiv is built by the Morning Brew team and centers on newsletters rather than traditional email marketing. It includes built-in growth features, reader insights at subscriber level, and access to its ad network for monetization. Founded in 2020, it's now the go-to for creators and publishers.

Perfect if you're growing a paid newsletter or creator business. Unlike Mailchimp's general-purpose tooling, Beehiiv's features (growth loops, monetization, referral tracking) are designed specifically for subscription newsletters.
