Overview

Inframail is an email infrastructure platform designed to streamline the setup and management of domains and mailboxes for cold outreach campaigns. It automates traditionally manual tasks such as DNS configuration, email authentication (SPF, DKIM, DMARC), and mailbox creation. Built on Microsoft's cloud platform with reputable IPs, the platform provides Microsoft-backed deliverability, unlimited inboxes at a flat price, and features like Phantom redirects to hide domain redirects from ESPs. It supports high sending volumes with IP rotation and deliverability safeguards to minimize spam issues and optimize inbox placement. Inframail integrates with popular cold email tools like Instantly.ai, Smartlead, and ReachInbox. Pricing is subscription-based with two main plans: Unlimited Plan at $147/month (400 mailboxes, 80,000 emails/month, 1 dedicated US IP) and Agency Pack at $297/month (1000 mailboxes, 300,000 emails/month, 3 dedicated US IPs), both including unlimited inboxes and domain setups. It is best suited for teams managing multi-domain outreach campaigns who require a centralized, scalable infrastructure.
