Mailpool is the infrastructure layer for cold emailโ€”designed to automate domain and inbox setup while maximizing deliverability at scale. It empowers outbound teams, sales agencies, and growth marketers to run high-performing email campaigns without the technical hassle.

With Mailpool, you can bulk-purchase domains, spin up inboxes across Google Workspace, Microsoft 365 Outlook, or custom SMTP providers, and automatically configure critical records like SPF, DKIM, and DMARC. This ensures your emails land in inboxesโ€”not spam foldersโ€”right from day one.

The platform connects seamlessly to any outreach tool via SMTP and IMAP or through native integrations, giving you full flexibility. Whether you're managing 10 inboxes or 1,000, Mailpool makes it easy with bulk creation tools, AI-powered domain recommendations, team management, and real-time deliverability tracking.

Built for scale, Mailpool combines reliability, affordability, and automation into one streamlined solution. Pricing starts at just $3 per inbox per month, making it ideal for outbound teams who need robust, ready-to-use infrastructure without breaking the bankโ€”or dealing with complicated setup.
