Key Takeaways
Centralized Messaging Saves Time. Manage guest, owner, and supplier conversations from one place—no more switching between platforms.
WhatsApp and SMS Expand Your Reach. Guests expect communication on their terms. Avantio’s optional add-ons include verified WhatsApp and global SMS messaging.
Faster Responses = More Bookings. Real-time OTA sync and notifications help teams respond quickly and improve conversion rates.
Built for Teams, Not Just Inboxes. Assign messages, tag threads, and track outcomes across bookings and tasks—all inside your vacation rental software.
When your team is bouncing between Airbnb, Booking.com, WhatsApp, SMS, and email just to keep up with conversations, efficiency breaks down. Bookings get lost. Maintenance issues go unresolved. And your team burns out trying to catch up.
Avantio’s Unified Inbox changes that.
This fully integrated communication hub centralizes your conversations across OTAs, email, SMS, and WhatsApp—all within your vacation rental management software.
What is a Unified Inbox in Property Management?

A unified inbox consolidates all communication with guests, owners, and service providers into one place.
- Instead of switching between multiple platforms, your team can:
- View and reply to Airbnb, Vrbo, and Booking.com messages in real time
- Assign threads to specific team members or properties
- Send PDFs, contracts, maps, and videos
- Track conversation outcomes and link them to bookings, tasks, or operational flows
At Avantio, the Unified Inbox is part of a powerful all-in-one solution that combines your PMS, channel manager, and booking website in a single ecosystem.
Why Do Property Managers Need a Unified Inbox?
1. Because Delayed Responses Cost You Bookings
Platforms like Airbnb track how quickly you reply—and rank you accordingly.
Your Unified Inbox should have:
- Real-time syncing with Airbnb, Vrbo, and Booking.com
- Push notifications and SLA tracking (coming soon)
- Templates for auto-responses, scheduled messages, and check-in details
2. Because Your Team Needs Ownership and Clarity
When messages sit in a shared Gmail inbox, things fall through the cracks.
Your Unified Inbox should have:
- Assign messages to specific team members
- Add internal notes to threads
- Tag conversations as “Urgent,” “Pending Payment,” or “Resolved”
- Track who’s handling what
This reduces errors, improves accountability, and saves time during handovers.
3. Because Guests Don’t Just Use Email Anymore
Your guests are on WhatsApp and SMS—so you should be too.
Your Unified Inbox should have:
- A verified WhatsApp Business number linked to your agency (not a shared mobile!)
- SMS messaging for local and international guests (through approved providers)
- All messages—OTA chats, email, WhatsApp, and SMS—stored together for full visibility
4. Because It’s Not Just About Guest Messaging
You can also use the Unified Inbox to:
- Communicate with property owners—sharing reports, availability, and payments
- Manage supplier conversations linked to tasks or bookings
- Route maintenance requests directly to the right provider, with photos or audio attached
Every stakeholder has a clear communication line—timestamped, stored, and assigned to the right property.
Did you know? 69% of vacation rental guests said that communication influenced their likelihood to leave a positive review.
“Isn’t My Current Inbox Good Enough?”
Maybe. But ask yourself:
- Can your current tool handle Airbnb, Booking.com, email, and WhatsApp in one place?
- Can you assign threads to your team and add internal notes?
- Can you trigger a maintenance task from a conversation thread?
If not, you’re wasting time, risking errors—and leaving bookings on the table.

What is a unified inbox?
A unified inbox centralizes communication from multiple sources (OTAs, email, WhatsApp, SMS) into one interface so your team can manage everything from one place.

No. The Unified Inbox is fully integrated within Avantio’s all-in-one software suite (PMS + Channel Manager + Website). It’s not a standalone tool.
