Description
SubsiMail is a platform for self-hosted cold email sequencing, allowing users to manage prospect lists, templates, connected inboxes, and all campaign-related data directly within their own database rather than relying on a third-party SaaS solution. Designed as an alternative to platforms like Instantly, Smartlead, lemlist, and Apollo, it offers flat pricing based on connected inboxes instead of per-seat charges, ensuring complete ownership and export of data without any content review processes or external access to contacts and campaigns. The application operates seamlessly as a single Docker container on any $5 VPS, enabling users to connect to Gmail, Outlook, or any SMTP/IMAP inbox, create multi-step email sequences that incorporate merge fields and reply detection, manage user roles (admin, manager, view-only) while maintaining a comprehensive audit trail, and utilize integration through a REST API secured by personal API keys. Furthermore, the initial connected mailbox comes with a perpetually free option, making it an attractive choice for individuals and businesses alike. This unique setup empowers users with greater control over their email marketing campaigns while simplifying the management process.
