Write, design, and send newsletters, with tools for growing and managing your subscriber list.
Newsletter software is primarily about publishing to a subscriber audience, but the products split between general marketing platforms and creator-first publishing systems. Important differences include the writing workflow, signup pages, audience segmentation, paid-subscription support and how much automation surrounds a regular broadcast.

For business newsletters
#1 of 14 in Newsletter Software
Mailchimp provides a visual email editor, templates, audience segments and campaign reporting inside a broader marketing platform. Consider it when newsletters sit alongside promotions, forms and customer automations instead of functioning as a standalone publication; integrations with common commerce and website tools also make it practical for business lists built from several acquisition sources.
Email plus messaging
#2 of 14 in Newsletter Software
Brevo (formerly Sendinblue) combines newsletter campaigns with automation, contact management and additional messaging channels. The result helps businesses that expect their newsletter audience to feed into broader customer communications beyond an isolated list. The platform is a fit when marketing teams want campaign sending and transactional or lifecycle communication under one vendor.
Straightforward publishing
#3 of 14 in Newsletter Software
MailerLite keeps newsletters, forms, landing pages and subscriber automation in a focused interface. This is relevant for teams that want to build a list, publish regular sends and create a few automated sequences without adopting a larger CRM environment; the website and signup tools also help smaller publishers manage acquisition around the newsletter itself.
Publication-first newsletters
#5 of 14 in Newsletter Software
Substack combines newsletter publishing with a hosted publication, subscriber management and paid-subscription capabilities. The writing and publishing model is closer to running an independent media property than configuring a marketing campaign system.
For creator audience growth
#8 of 14 in Newsletter Software
Kit (formerly ConvertKit) is built for creators using email to grow and monetize an audience. It combines broadcasts, visual automations, landing pages and subscriber tagging with creator-oriented commerce and recommendation features. The result is a better fit than a generic campaign platform when newsletters, digital products and audience relationships are central to the business model.

Creator-first platforms treat the newsletter and audience as the main product, often adding hosted publishing, paid subscriptions, recommendations or digital-product features. General email platforms treat newsletters as one campaign type among automations, promotions and other customer communications.
Not always, but simple automations can improve onboarding and retention. Welcome sequences, interest tagging and re-engagement flows can run around the regular editorial broadcast without changing the publication's main cadence.
