A real email address
for your AI sales agent.
Every AI SDR tool needs a dedicated sending identity with domain reputation. Without DKIM signing and a stable sender identity, 90% of outreach lands in spam. Mailgent gives each sales agent its own email address, threaded conversations, and LLM-ready reply extraction — so your outreach actually reaches inboxes.
API Primitives used
mail.sendDKIM-signed outreach
Send personalized cold emails from a dedicated agent address with proper DKIM, SPF, and DMARC. Build sender reputation that keeps you out of spam folders.
mail.list_messagesMonitor for replies
Poll for new messages or receive via webhooks. extractedText strips quoted replies so your LLM gets clean prospect responses without noise.
mail.replyThread-aware follow-ups
Reply in the same thread automatically. In-Reply-To headers are handled for you — conversations stay organized without custom threading logic.
AI sales agents need their own sending identity.
Every AI SDR product — 11x, Artisan, Regie.ai, and every custom-built outbound agent — hits the same infrastructure wall: sending emails that actually reach inboxes. Without a dedicated sending identity with DKIM signatures and domain reputation, outreach emails land in spam. Without threading, follow-ups don't connect to the original conversation. Without reply extraction, your LLM wastes tokens on quoted reply noise.
Most teams work around this with SendGrid or SES, but these are transactional email services — not agent identity infrastructure. They don't give each agent its own address. They don't handle threading. They don't extract clean text for LLMs. And they don't provide the audit trail and delegation chain that enterprise buyers increasingly demand from AI-powered outreach.
Mailgent gives each sales agent a dedicated email address with DKIM-signed outbound, automatic thread stitching, and LLM-ready text extraction. Your agent sends from its own address, monitors for replies, and follows up in-thread — all through a single API.
How to build it.
Create a sales agent identity
Provision a dedicated identity with its own email address (e.g., sales-x8k2m@mailgent.dev). DKIM, SPF, and DMARC are configured automatically. The agent has its own sender reputation.
mail.sendSend personalized outreach
Send personalized cold emails with your LLM-generated content. Each email is DKIM-signed from the agent's own address. Build sender reputation with proper warm-up cadence.
mail.list_messagesMonitor and follow up
Poll for replies using labels (unread, replied). extractedText gives your LLM the clean prospect response. Reply in-thread with context-aware follow-ups.
Example prompt
“Send a personalized follow-up to every prospect who opened but didn't reply to last week's outreach. Reference their specific use case. Track which follow-ups get responses.”
What sales teams build.
Cold outreach at scale
Agent sends personalized cold emails to hundreds of prospects from its own professional address. DKIM signing and stable sender identity keep deliverability high. Each prospect gets a unique, context-aware message generated by your LLM.
Automated follow-up sequences
Agent monitors for replies, waits the appropriate interval, and sends follow-ups in the same thread. Warm leads never slip through the cracks. Thread stitching means the full conversation history is always visible to the prospect.
Lead qualification via email
Agent engages prospects in email conversations, asks qualifying questions, extracts key signals from responses using extractedText, and scores leads. Qualified leads are escalated to human sales reps with full conversation context.
Meeting scheduling
Agent reads incoming meeting requests, checks availability using stored calendar API credentials from the vault, and sends calendar invites. Follow-up confirmations and reminders are sent in-thread automatically.
CRM-integrated pipeline management
Agent retrieves CRM API credentials from the vault, updates deal stages based on email conversations, and sends pipeline digest emails to sales managers. Every prospect interaction is logged and attributed.
Multi-agent sales team
Deploy specialized agents — one for initial outreach, one for follow-ups, one for scheduling. Each has its own identity and inbox. Agents hand off prospects to each other via email, maintaining full conversation context.
Why not SendGrid or SES?
SendGrid and SES are transactional email services built for sending notifications and receipts from applications. They're not agent identity infrastructure. They don't give each agent its own persistent email address. They don't handle threaded conversations. They don't extract clean text for LLMs. And they don't provide the delegation chain that proves your AI agent is authorized to send on behalf of your organization.
Mailgent is built specifically for AI agents. Each agent gets a dedicated address with its own sender reputation. Threading is automatic via In-Reply-To headers. extractedText strips quoted replies so your LLM context window isn't wasted on noise. And every email carries a delegation chain — critical for enterprise buyers who need to know that AI outreach is authorized and attributable.
DKIM + SPF + DMARC
Every outbound email is cryptographically signed. Recipient email providers can verify the sender. Spam folder avoidance starts with proper authentication.
Full audit trail
Every email sent and received is logged with timestamps, delivery status, and agent identity. Enterprise buyers can audit exactly what your AI SDR sent.
CRM credentials encrypted
Salesforce, HubSpot, and other CRM API credentials stored in the vault with AES-256-GCM encryption. Scoped per agent — one agent can't access another's integrations.
