What is Listmonk?
Listmonk is a high-performance, self-hosted newsletter and mailing list manager packed into a single binary. Free and open-source under AGPLv3, Listmonk handles millions of subscribers across single and double opt-in lists with SQL-based querying and segmentation. The platform features multi-threaded, high-throughput, multi-SMTP email queues with sliding window rate limiting for fine-grained control. Beyond email campaigns, Listmonk supports transactional emails, SMS, WhatsApp, and any medium via Messenger webhooks. The nominal CPU and memory footprint means it runs anywhere – from a Raspberry Pi to enterprise servers.
