AlienMail

AlienMail is an AI cold email software that writes sequences, warms inboxes, and optimizes campaigns.

AlienMail is an artificial intelligence cold email platform designed for agencies, startup founders, sales development representatives, and recruiters. It builds a business DNA profile from your website details to automatically write personalized email sequences, configure cadence, and structure follow-ups. Users upload leads and connect mailboxes via Gmail, Outlook, or custom SMTP using Zapmail. The software runs continuous background warmup to build sender reputation and flags misconfigured DNS records like SPF, DKIM, and DMARC. It also features a native Model Context Protocol server that lets users run campaigns directly from Claude or ChatGPT. All templates and sequence steps remain fully editable after generation.
