How to Automate Guest Messaging with a PMS

If you manage a vacation rental, you type the same phrases over and over: "Here is the wifi password," "Check-out is at 11 AM," and "The door code is..."

Manual messaging is the biggest time-sink in hospitality. By using a Property Management System (PMS) with an automation engine, you can put 90% of your guest communication on autopilot, ensuring guests get exactly what they need, exactly when they need it, even if you are asleep.

Here is how to set up automated guest messaging effectively.

The 5 Essential Automated Messages

You do not want to spam your guests. An effective automation flow consists of exactly five messages.

1. The Booking Confirmation

Trigger: Immediately upon a confirmed booking. Goal: Reassure the guest, set expectations.

Template:

Hi [Guest First Name],

Thank you for booking [Property Name]! Your reservation for [Check-in Date] to [Check-out Date] is confirmed.

I will send you detailed check-in instructions, including your personalized door code and wifi details, exactly 48 hours before your arrival.

If you have any questions in the meantime, feel free to ask.

Best, [Host Name]

2. Pre-Arrival (The "Logistics" Message)

Trigger: 48 hours before check-in time. Goal: Prevent the guest from asking "how do I get in?"

Template:

Hi [Guest First Name],

We are looking forward to hosting you in two days! Here is everything you need for your stay at [Property Name]:

📍 Address: [Property Address] 🕒 Check-in time: Anytime after [Check-in Time] 🔑 Door Code: [Door Code] (To use, press the Yale logo, enter code, and press checkmark). 📶 WiFi: [Wifi Network] / [Wifi Password]

Safe travels, and let me know when you arrive!

3. The "Morning After" Check-In

Trigger: 9:00 AM the morning after check-in. Goal: Catch small issues before they become bad reviews.

Template:

Good morning [Guest First Name],

I hope you slept well! Just checking in to make sure you found everything okay and that the house is perfectly clean.

If you need anything at all, just reply to this message. Enjoy your day!

4. Check-out Instructions

Trigger: 4:00 PM the day before check-out. Goal: Ensure a smooth departure for your cleaners.

Template:

Hi [Guest First Name],

I hope you've had a wonderful stay! Just a quick reminder that check-out is tomorrow by [Check-out Time].

Before you leave, we just ask that you:

• Start the dishwasher
• Turn off the AC/heating
• Lock the front door behind you

Have a safe trip home!

5. The Review Request

Trigger: 24 hours after check-out. Goal: Farm 5-star reviews automatically.

Template:

Hi [Guest First Name],

Thank you so much for choosing to stay with us! You were fantastic guests, and I have already left you a 5-star review.

If you enjoyed your stay, I would be incredibly grateful if you could take 60 seconds to leave us a review. It helps our small business tremendously.

Hope to host you again!

How PMS Dynamic Variables Work

The secret to automated messaging that doesn't feel like a robot is dynamic variables (also called shortcodes).

When you set up templates in a PMS like BookBed Pro, you insert placeholders. When the trigger fires, the PMS queries the reservation data and swaps the placeholder for the real data.

• [Guest First Name] becomes Sarah
• [Door Code] becomes 8492

This means you write the template once, and it personalizes itself for every single guest across Airbnb, Booking.com, and direct bookings automatically.

Best Practices for Automation

• Don't over-automate: Keep automation strictly for logistics. If a guest asks a specific question ("Do you have a blender?"), answer it manually via your unified inbox.
• Format for mobile: 80% of guests read messages on their phones. Keep paragraphs short and use emojis (📍 🔑 📶) as visual bullet points to make scanning easy.
• Audit your templates yearly: Ensure your wifi passwords, door code instructions, and check-out times in the templates match reality.

Frequently asked questions

What is the difference between a PMS and a channel manager? A channel manager syncs calendars across platforms. A PMS (property management system) does that plus handles guest messaging, payments, invoicing, reporting, and operations. Most modern tools combine both into a single platform.

Do I need a PMS if I only manage 1–3 properties? You don't strictly need one, but even small hosts benefit from automated messaging, centralized calendars, and professional invoicing. A lightweight PMS like BookBed starts at €9/month and saves hours of manual work each week.

How do I switch from one PMS to another? Export your reservation data and calendar feeds from your current PMS. Set up the new PMS with your OTA credentials and import your listings. Most transitions take 1–2 hours. Run both systems in parallel for a week to verify sync before deactivating the old one.
