What is mailX by mailwarm?

mailX by mailwarm is the evolution of the mailwarm platform, now with native support for AI agents that need to send emails at scale. It solves the biggest problem of automated email marketing: deliverability. With automatic warming of outboxes, reputation monitoring, and real-time diagnostics, mailX ensures that your emails reach the inbox.

How it works

Connect your email account to mailX and it starts the warming process automatically: it exchanges real emails with a network of email inboxes to build sender reputation. For AI agents, it provides an API to check domain health before each campaign and automatically adjusts sending volume to avoid blocks.

Key features

  • Automatic Warming: Builds sender reputation gradually with real emails.
  • Reputation Monitoring: Tracks domain score, blacklists, and spam score in real time.
  • API for Agents: Dedicated endpoints for AI agents to check health before sending.
  • Deliverability Diagnosis: Identifies SPF, DKIM, DMARC, and server configuration issues.
  • Detailed Reports: Dashboard with open, spam, and reputation metrics by provider.

Who is it for

  • Sales teams that depend on cold email for lead generation.
  • Agent developers whose AIs send emails automatically.
  • Marketing agencies managing multiple client domains.
