COMMUNICATION CHANNELS

Email

How D3x works hotel email: a copilot plugin in Outlook, Gmail, Freshdesk, and Zendesk that one-click drafts from the live PMS, and Agentic Email that classifies the inbox, closes notifications, and replies to FAQs under confidence and GDPR guardrails.

  • Email copilot in Outlook, Gmail, Freshdesk, Zendesk
  • One-click draft with PMS and knowledge base
  • Human guidance on exceptions
  • Agentic Email inbox classifier
  • Auto-close notifications
  • FAQ send, draft, or leave untouched
  • GDPR special-category hold

Hotel email is two products on one D3x agent, not a mailbox chatbot. Email copilot drafts inside the thread a person is already working. Agentic Email watches the inbox, classifies each message, and acts only where the property has said it may.

The copilot is the email plug-in in the messaging subscription (€5 per room per month). Agentic Email is priced separately and is currently in beta. Both use the same knowledge base, property email personality, signature, and PMS connection as WhatsApp and phone. See Skills Engine and Pricing.

Email copilot

Plugins sit in Outlook, Gmail, Freshdesk, and Zendesk. On the open thread, the user clicks once. That click sends the thread to D3x with full context. D3x then drafts a reply the user can send from the same inbox or helpdesk.

Static context

Knowledge base, the property's email personality, and the email signature wrap every draft so it reads as the house, not a generic assistant.

Live PMS context

D3x searches the PMS by the sender's email address. If a reservation exists, the draft uses that stay. It can also read rate plans, rates, availability, and room types so availability answers are current.

  1. User opens a thread in Outlook, Gmail, Freshdesk, or Zendesk
  2. One-click copilot sends the thread and context to D3x
  3. D3x searches knowledge base and PMS (reservation, rates, availability, room types)
  4. Draft is written in the property personality, with signature
  5. User reviews and sends from the same tool

The guest never leaves email. The team never copies the thread into another product.

Advanced copilot: human guidance

The user can add a short instruction before the draft runs. That instruction is treated as an exception the agent would not assume on its own.

Example: a guest writes that they are travelling with children, arriving at 09:00, and asks for free early check-in because they always stay. The user types yes. The copilot drafts a confirmation of the free early check-in, using the reservation it found from the email address, instead of quoting the standard check-in time.

Agentic Email

Agentic Email connects to the mailbox and scans every incoming message. A pipeline runs before anything is sent, closed, or left alone.

Step 1: classify

Each email is classified as one of:

  • Notification: system or OTA mail that usually needs no human action
  • Guest request: a person asking a question or making a request
  • Marketing
  • Spam

Marketing and spam are labelled so they are not treated as guest requests. What happens next is configured for notifications and guest requests.

Notifications: close without troubling the desk

Many properties receive a high volume of notifications that they keep for audit but never act on. A common case is Booking.com sending an email that a reservation was made. That booking already flows through the channel manager into the PMS. The team does not need to open it.

If the property turns this on, Agentic Email closes those notifications. The mail remains available if something has to be investigated later. The desk is not asked to file it by hand.

Guest requests: send, draft, or do not touch

For a guest request, the agent searches the knowledge base and scores confidence. What it does next is a property setting, not a single global switch.

High confidence

A clear FAQ, for example bicycle rental or breakfast. The agent replies immediately from the knowledge base, in the property personality, with signature.

Not high confidence

The agent writes a draft and leaves it in the inbox. A human reviews and hits send. Nothing goes out until they do.

Low confidence

The agent does not touch the email. The thread stays as it arrived for the team to handle.

Agentic Email pipeline: classify first, then close, send, draft, or leave the thread alone.

Guardrails

Before Agentic Email sends or drafts, it scans the message against property guardrails. Threads that match are not auto-replied.

  • Legal tone
  • Complaint tone
  • Legal language

Those emails stay for a human. The copilot can still be used on the same thread if someone opens it and clicks for a draft.

Special-category data (GDPR)

If an email contains special-category data under GDPR, Agentic Email does not process it. Related records are deleted from the database. The scan includes:

  • Health information
  • References to politics
  • References to religion

This is a hard stop, not a confidence threshold. See Security and privacy and Trust.

Go-live

Copilot go-live is the plugin in Outlook, Gmail, Freshdesk, or Zendesk, plus the property email personality, signature, and the same PMS connection used on other channels. Agentic Email is scoped separately: which mailbox, which notification types to close, whether FAQ auto-reply is on, and which guardrails apply.

Apply for the Agentic Email beta from the add-ons section on Pricing. The copilot plugin is part of messaging at €5 per room per month.
