Mailpool

Mailpool is a cold email infrastructure platform designed to help teams scale outreach with reliable, high-performance inbox infrastructure.

It simplifies setup with features like bulk domain purchasing, inbox creation across Google Workspace, Microsoft 365 Outlook, or custom SMTP providers, and automatic configuration of SPF, DKIM, and DMARC—ensuring your emails reach inboxes, not spam folders, from day one.

Mailpool integrates with any outreach tool via SMTP and IMAP, and offers native integrations for added convenience. It’s built for scale, supporting bulk inbox creation, AI-generated domain suggestions, team management, and real-time deliverability monitoring.

By combining affordability, simplicity, and strong deliverability, Mailpool eliminates the technical complexity of managing cold email infrastructure.

Pricing starts at just $3 per inbox per month, making it a go-to solution for outbound agencies, sales teams, and any organization looking to scale campaigns without the backend burden.
