listmonk
An open mailing manager with subscribers, segments, campaigns, templates, analytics, APIs, and transactional messages using chosen delivery providers.
Why use it
Technical teams can control beta and community lists and send release updates and devlogs with low software cost.
Where it fits
Use analytics, feedback, player support, and updates to fix issues and decide what to improve after launch.
What to check
Email delivery still costs and needs operations, while administrators own unsubscribe, anti-spam, privacy, backups, and sender-domain reputation.
