Self-hosted deployment
Runs from a self-hosted install so the sending stack lives on the buyer’s own server rather than a hosted SaaS account.
Self-hosted cold email infrastructure for agencies
Cleanmails is a self-hosted cold email platform for agencies and other teams that want to run outreach, validation, warmup, and reply handling from their own server. The homepage positions it as an alternative to subscription-based cold email tools, with a one-time purchase model and an install flow aimed at getting a VPS ready for sending quickly.
The product combines an inbuilt mail server, sender rotation, list validation, multi-step sequences, and AI-assisted replies in one installation. The site also emphasizes setup support, documentation, and isolated client workspaces for teams that need to manage multiple accounts from a single dashboard.
