Stalwart Labs

Stalwart Labs' mission is to help modernize, democratize and promote decentralization of email by creating an open-source mail server. Put simply, it is about building software for you when nothing off the shelf fits.

Who is it for? Mostly companies with a specific process to automate. They also list Email, so expect those to show up in the feature set. They are a very small team, 1 to 10 people, which usually shapes who they work with. Small vendors mean quick answers and real influence on the roadmap, but check who covers support when someone is out.

Stalwart Labs is based in Sheridan, Wyoming. More on stalw.art.

Our checklist for this category: portfolio relevance, who owns the code, and how they handle changes. A short pilot with your real data tells you more than any demo.
