Email & Newsletter Market: Developer-Focused Newsletter Platform Comparison

Zusammenfassung des Signals

This technical comparison evaluates six newsletter platforms (Beehiiv, Kit, Mailchimp, Substack, Ghost, MailerLite) from a developer perspective. It breaks newsletter platforms into core layers — email delivery, subscriber management, content engine, public website, monetization, and developer surface — and examines API quality, webhooks, DNS/custom domain control, template customization, data portability, and deliverability. The article finds Kit and Ghost offer the best developer APIs, Ghost provides the strongest data portability (open-source and self-hostable), Beehiiv balances power and simplicity, Mailchimp delivers the deepest feature set at the cost of complexity, and Substack prioritizes simplicity but limits API and webhook access. The piece emphasizes verifying exportability of critical datasets, webhook authentication/retry behavior, sender authentication (DKIM/SPF/DMARC), and payment ownership before committing to a platform.
