# SubsiMail

> Self-hosted cold email sequencing platform. Prospect lists, templates, connected inboxes, and campaign data live in your own database, not a third-party SaaS -- flat per-inbox pricing, no content review, no per-seat fees.

SubsiMail is a self-hosted alternative to Instantly, Smartlead, lemlist, and Apollo. It runs as a single Docker container on your own server and connects to Gmail, Outlook, or any SMTP/IMAP inbox.
