About

SubsiMail is a self-hosted cold email sequencing platform. Prospect lists, templates, connected inboxes, and all campaign data live in your own database, not a third-party SaaS. It's built as a self-hosted alternative to Instantly, Smartlead, lemlist, and Apollo, with flat per-inbox pricing instead of per-seat fees, full data ownership and export, no content review, and no third-party access to your contacts or campaigns. Runs as a single Docker container on any $5 VPS. Connect Gmail, Outlook, or any SMTP/IMAP inbox; build multi-step sequences with merge fields and reply detection; manage per-user roles (admin/manager/view-only) with a full audit trail; and integrate via a REST API with personal API keys. The first connected mailbox is free forever.

About

fkngrow is a web-based AI prospecting tool for founders and small businesses. Users provide their website to generate an editable ideal customer profile with suggested industries, company sizes, seniority levels, and job titles, then identify matching companies and find business contacts with verification status and confidence information. The tool drafts cold emails based on the user's positioning and can send them through the user's Google Workspace, personal Gmail, or SMTP/IMAP mailbox, with user-set daily sending limits. Growth Autopilot can run prospect discovery and email sending daily and email a recap after each run. Sending safeguards include verification before sending, a maximum of 15 contacts per company, a minimum seniority setting, and permanent exclusions. The free plan includes 25 discoveries and 25 emails per month with no card required. Pro costs $29 per month and includes 2,000 discoveries and 6,000 emails.
