Hey! I'm Matthew, the developer behind Warmbly.
I've been building Warmbly for a little over a year because I wanted an open-source alternative for cold outreach that gives users more control instead of locking everything behind a SaaS.
It's still early, but it already supports campaigns, email warmup, automations, analytics, and team collaboration. I'm now working on the hosted version and a mobile app.
I'd really appreciate any feedback, ideas, or criticism. Thanks for checking it out!
A solid open-source alternative to the usual outreach tools, love that warmup is included. One thing that would really help my workflow is a built-in deliverability dashboard that shows bounce rates and spam scores per campaign in real time, so I can pause or tweak sequences before they tank my sender reputation.
Would love to see a built-in deliverability score that shows inbox placement rates per domain before sending. Right now I have to bounce between tools to check if my campaigns are actually landing in primary inboxes, would be huge to have that live in the Warmbly dashboard.
The split between the AI agents and email warmup on the homepage actually makes sense visually, each piece gets its own breathing room instead of blending into another generic outreach tool page. Nice execution on the open-source angle too, feels honest rather than tacked on.
