How it works

Three steps to agentic email

Connect any AI agent to your inbox in minutes. No custom integration required.

1

Connect via MCP

Your AI agent connects to Mailtron's MCP server using the open standard. Authenticate with OAuth and request the scopes it needs — read, draft, send, search, or manage.

2

You set the rules

Approve which actions the agent can take. Set confidence thresholds for autonomous actions. Review queued drafts before they send. Full audit trail of every agent action.

3

Agent works for you

The agent triages your inbox, drafts replies in your voice, schedules meetings, manages follow-ups, and handles routine email — while you focus on what matters.

MCP Protocol

Every email operation,
one open standard

MCP (Model Context Protocol) is the open standard for AI agent tool use. Mailtron exposes every email operation as an MCP tool — search, read, draft, send, label, archive, schedule, and more.

  1. 1 Search — semantic and operator-based search across your entire inbox
  2. 2 Draft & Send — compose in your voice with per-recipient tone adaptation
  3. 3 Manage — label, archive, snooze, schedule, and organize autonomously

AI Triage

Every email scored,
prioritized, actioned

AI scores every incoming email 1–100 for priority. Recommends actions, pre-writes follow-ups, and auto-labels your inbox. High-priority items surface immediately. Low-priority goes to a daily digest.

  1. 1 Priority scoring — every email ranked by urgency, sender importance, and content
  2. 2 Action recommendations — AI suggests reply, forward, archive, or snooze
  3. 3 Auto-draft — AI pre-writes replies you review and send with one click
Voice Learning

Drafts that sound
like you wrote them

Mailtron learns your writing voice per recipient. Formal with your board. Casual with your team. Technical with engineers. Every draft adapts to the relationship, not just the words.

  1. 1 Per-recipient adaptation — different tone for different people, automatically
  2. 2 Style consistency — matches your greeting, sign-off, punctuation, and sentence structure
  3. 3 Confidence scoring — shows match percentage so you know when to review

Capabilities

Full agent toolkit

Every tool an AI agent needs to manage email effectively.

Semantic Search

Natural language queries across your entire inbox. "Find the contract John signed in March" just works. Powered by AI embeddings and operators.

Smart Drafting

AI composes replies that match your writing voice per recipient. Review, edit, and send with one click. Set auto-send thresholds for high-confidence drafts.

Scheduling

Agents schedule meetings by checking availability, proposing times, and handling back-and-forth. Timezone-aware with calendar integration.

Agentic Workflows

Multi-step autonomous sequences for sales outreach, customer support, invoice follow-ups, and meeting scheduling. Set it up once, agent handles the rest.

Security Scopes

OAuth-based scopes control exactly what each agent can access. Read-only, draft-only, or full access. Revoke anytime. Complete audit trail.

Thread Summarization

Agents extract key decisions, action items, and deadlines from long threads. Get the essential information without reading every message.
