Mailpool

Mailpool is a cold email infrastructure platform built to help teams boost outreach performance with reliable, scalable inbox infrastructure.

It streamlines setup by enabling bulk domain purchases, inbox creation across Google Workspace, Microsoft 365 Outlook, or custom SMTP providers, and automatic SPF, DKIM, and DMARC configuration—ensuring your emails land in inboxes from day one.

Mailpool connects easily to any outreach tool via SMTP and IMAP, or through native integrations. Built for large-scale operations, it supports bulk inbox creation, AI-powered domain suggestions, team management, and real-time deliverability monitoring.

By combining low cost, ease of use, and strong deliverability, Mailpool removes the complexity of manual setup and technical upkeep.

Starting at just $3 per inbox per month, it’s the ideal infrastructure solution for outbound agencies, sales teams, and anyone scaling cold email campaigns without the backend hassle.
