Are there any guest communication platforms that focus on automating check-in and checkout for short-term rentals?

Yes. There are several guest communication platforms built specifically for short-term rentals that automate check-in, checkout, and the guest messaging around those flows.

Some well-known options include:

• Hospitable — automates guest messaging, scheduled check-in/check-out instructions, reviews, and task workflows.
• Hostaway — property management + guest communication with automated messages, guest portals, and operational tools.
• Guesty — strong for short-term rental management, with automated messaging, check-in/out instructions, and guest communication workflows.
• Lodgify — includes automation for pre-arrival, check-in, during-stay, and checkout messages, plus a guest portal.
• Smoobu — offers automated guest messaging and templates for arrival/departure info.
• OwnerRez — supports automated messaging and guest communication sequences tailored to bookings.
• Your Porter App — focuses on messaging automation across channels and guest support workflows.

Features to look for if your main goal is check-in/check-out automation:

• Scheduled arrival and departure messages
• Digital house manuals / guest portals
• Self check-in instructions
• Automated review requests after checkout
• Channel integration with Airbnb, Vrbo, Booking.com, etc.
• Triggered messages based on booking dates or check-in status
