Overview

HotHawk is a cold email platform that consolidates multiple outbound email accounts (Google, Microsoft, IMAP/SMTP) into a unified master inbox. It includes an email sequencer with automatic inbox rotation, real-inbox warmup against a pool of 50,000+ Google and Microsoft mailboxes, and best-practice sending for deliverability. The master inbox captures every reply across all mailboxes, including forwarded and CC'd responses, and routes them to the right team member. Features include AI reply categorization, LinkedIn reply management, out-of-office handling, custom views, bounce tracking, mailbox handover, and a native MCP server for AI-driven workflow automation. Integrations include HubSpot, Salesforce (via OutboundSync), InboxKit, ZapMail, API, webhooks, and n8n. Pricing is based on monthly send volume with unlimited mailboxes, team members, leads, and workspaces on higher tiers.
