Best Email Tracking Software for Linux

Bitrix24 replaces a fragmented app stack with a single workspace combining CRM, project management, and collaboration tools. Trusted by 15 million companies, Bitrix24 brings all business operations into one central hub. The CRM manages lead tracking, automated pipelines, and an omnichannel contact center. For daily teamwork, Bitrix24 provides chats, HD video calls, shared calendars, corporate mail, and document co-editing, alongside Kanban boards and Gantt charts to track project dependencies. CoPilot AI assistant is embedded throughout the platform and serves as a secure assistant that handles routine writing, summarizes long client conversations, creates tasks from notes, and helps teams work faster. A generous free plan supports unlimited users. For growth, flat-rate pricing charges one fixed fee for the entire company, eliminating per-user costs. The mobile app gives remote access, while the self-hosted edition deploys on private servers with open source-code access.
