About

SendFlock is an all-in-one cold email platform designed to streamline outreach efforts by integrating email warm-up, automated follow-ups, a unified inbox, and CRM functionalities. Users can connect multiple email accounts, regardless of the service provider, and manage them through a single interface. It offers automated email sequences, allowing users to focus on pitching new leads while the system handles follow-ups. Its email warm-up tool ensures maximum deliverability by gradually increasing sending volume and engaging with a warm-up network to build sender reputation. The unified inbox consolidates all email accounts, improving response times and efficiency. SendFlock's CRM provides an immediate overview of the sales pipeline, helping users prioritize valuable deals. Additional features include AB testing to optimize outreach messages, custom tracking domains to improve deliverability, a global block list to protect sender reputation, team member management, etc.

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.
