Also searched as Resend vs listmonk — same comparison, one verdict.
listmonk
Self-hosted newsletters — a single binary handling millions.
listmonk is a self-hosted newsletter and mailing-list manager: subscriber management, segmentation, templates, analytics and bounce processing, as one Go binary with Postgres behind it. AGPL-3.0, around 23k stars, and documented as handling millions of subscribers on modest hardware. It is not a transactional sender — it hands off to SES or your own SMTP — which makes it a complement rather than a competitor. For anyone paying Mailchimp per subscriber for a newsletter, this removes that bill entirely.
Resend
The one developers enjoy — React templates and a clean API.
Resend is transactional email built for the way front-end teams work now: write your templates as React components with react-email, send through a simple API, and get a dashboard that shows what happened without archaeology. Around 20k stars on the open-source react-email library, though the sending service itself is proprietary and hosted. Pricing sits between SES and SendGrid. It earns its place because developer experience genuinely affects whether email templates get maintained, and unmaintained templates are how transactional email quietly rots.
