We self-host Kailash Nadh's listmonk at work.

It is a good fit for our needs as a lightweight, self-managed option. Setting it up was straightforward, and it integrates smoothly into our workflows. It gives us full ownership of our user database while providing useful collaboration, segmentation, and tracking analytics features.

Having it on our own server also puts us more in charge of security and privacy compliance. And the self-hosted model allows us to customize as our business needs evolve.

Even outside work, listmonk would be useful for managing personal projects (including Bear Blog newsletters). You can easily connect your Gmail SMTP credentials, also.
