They use it to launch domains and inboxes in minutes, warm them up, and keep sender reputation in check so deliverability stays strong. Over 500,000 inboxes have been created on the platform. Teams run it from the dashboard, sequencers and AI SDR platforms build it into their own product through the API, and AI agents use it directly from Claude or a terminal through the MCP server. Key features: - Domains and inboxes Buy domains in bulk across 300+ TLDs, with AI name suggestions and domain history checked before purchase. Create inboxes on official Google Workspace and Microsoft 365 business licenses or on Mailpool's own SMTP infrastructure, and mix providers in one account. Sender names, signatures and reply forwarding are set up for you. - Automated DNS and monitoring SPF, DKIM and DMARC are configured on every domain, so inboxes are ready to send in about 5 minutes, and every domain and inbox is monitored for DNS health and blacklisting. - Deliverability testing: Inbox placement tests across 8 email providers with an inbox, spam and promotions breakdown per provider, and a spam check across 250+ checkpoints and 50+ blacklists. - Warmup: Build sender reputation on a private warmup network of 60,000+ inboxes before campaigns start. - Export, API and MCP: Export inboxes in one click to Smartlead, Instantly, lemlist, EmailBison, PlusVibe and 100+ other tools, or by CSV. A full API, real-time webhooks and an MCP server let your own systems and AI agents, such as Claude, create domains, inboxes and placement tests programmatically. Mailpool is priced per mailbox per month, with no setup fee. ![Mailpool](https://images.g2crowd.com/uploads/product/image/large_detail/large_detail_6626b8c4b2fd61851639a8509b4eb439/mailpool%282%29.png "Mailpool") Mailpool Discussions Most CommentedMost HelpfulCommon QuestionsNewest Showing **1** discussion ![Nikola P.](/assets/transparent-ad5be28fbcd25b7b08d2cebe1d957125437fb5407d75ee717965ad22c8808791.gif "Nikola P.")
