9 channels, one view
WhatsApp, Instagram, Facebook Messenger, LINE, Gmail, and the Airbnb, Booking.com, VRBO and Expedia inboxes — every conversation unified into one thread per reservation.
Every guest message.
One inbox.
Stop switching between apps to keep track of guest messages. See and reply to every conversation — WhatsApp, Instagram, Facebook Messenger, LINE, Gmail, and the Airbnb, Booking.com, VRBO and Expedia inboxes — from a single inbox, with one thread per reservation.
9 channels. 9 inboxes. Zero peace of mind.
You wake up, open the Airbnb app to check messages. Then Booking.com's extranet. Then WhatsApp. Then Facebook Messenger. Then Instagram DMs. Then VRBO, Expedia, LINE and email.
By the time you've checked everything, a new message arrived on the first platform. You missed it. The guest is frustrated. Your response time tanks. Your ranking drops.
Managing guest communication across multiple channels isn't just exhausting — it's costing you bookings and reviews.
One inbox for every channel.
SympleHost's Unified Inbox brings all your guest communication into a single view: WhatsApp, Instagram, Facebook Messenger, LINE, Gmail, and the Airbnb, Booking.com, VRBO and Expedia inboxes — all in one place.
Every message shows the guest's name, booking details, property, and platform of origin. You can reply from the same inbox, and your response goes back through the original channel. Guests never know you're using a different tool.
Turn on AI Autopilot mode, and Amy AI handles routine questions automatically. You only step in for messages that need a human touch.

Why a built-in inbox beats standalone tools.
Tools like Guesty or Hospitable offer messaging, but they typically support fewer channels, don't include WhatsApp, and charge extra for AI features. SympleHost's Unified Inbox is different because every message is automatically connected to:
- The guest's profile and booking history
- The property's details and house rules
- The calendar for availability context
- Amy AI for intelligent auto-responses
- Operations for task coordination
When a guest asks about early check-in, you don't just see their message — you see their booking, the cleaning schedule, and the property's availability in one glance. No separate messaging subscription needed. It's all part of SympleHost.

Guest messaging FAQs
What's the best tool for aggregating all guest messages into a single place?
A unified inbox that connects directly to every channel your guests use, rather than forwarding messages to email. SympleHost aggregates WhatsApp, Instagram, Facebook Messenger, LINE, Gmail, and the Airbnb, Booking.com, VRBO and Expedia inboxes into one thread per reservation, so a guest who asks on Instagram and follows up on WhatsApp appears as a single conversation with their booking details attached. Replies go back out through the original channel.
How can I keep track of all guest messages without switching between apps?
Connect each channel once, then work from a single screen. Every message arrives with the guest's name, property, check-in and check-out dates and full history beside it, so you do not need the Airbnb app, the Booking.com extranet and three social apps open to know what is going on. Messages sync in real time, so nothing waits for a refresh.
Is there a unified inbox that can handle all communication channels?
SympleHost handles nine: WhatsApp, Instagram, Facebook Messenger, LINE, Gmail, and the Airbnb, Booking.com, VRBO and Expedia inboxes. Each conversation is grouped by reservation rather than by channel, which is what stops the same guest appearing as three separate threads.
How can I manage guest messages more efficiently across different platforms?
Filter by channel, property or status to work through what matters first, save your common replies as templates, and turn on AI Autopilot so routine questions — check-in times, wifi codes, parking — are answered automatically in the guest's own language. You step in only when a message needs a human decision.
How is a built-in unified inbox different from a standalone inbox tool?
A standalone inbox only sees messages. Because the inbox is built into the platform that also holds your calendar, rates and reservations, every conversation already knows which booking it belongs to — so replies can quote real arrival dates and balances, and automations can trigger from them. There is no second subscription and no syncing between two systems.
What are the best platforms for guest support automation in vacation rentals?
The best guest-support automation resolves questions on its own instead of drafting suggestions a human must approve. SympleHost's AI concierge answers free-text guest questions in the guest's own language across WhatsApp, Instagram, Facebook, LINE, Gmail and the OTA inboxes, escalating to you only on your rules — so 24/7 coverage doesn't require a night shift. Rule-based tools like Hostaway and tier-gated AI like Guesty's automate less of the conversation end-to-end.
