Custom Booking Messages (Communication → Message Automations)

Your automated emails to guests who have booked all live in one place: Communication → Message automations. You can edit Haven's built-in messages there, and you can add your own, such as a note the day after check-in, a door-code reminder, or a question a week before arrival.

Message automations are not marketing. Use Communication → Message automations for anything about a stay. Marketing → Campaigns is for promotional mail (broadcasts, win-back, Smart offers) to your audience.

Two Lists on the Same Page

Communication → Message automations (/host?tab=messages&msgView=booking) shows:

Haven's automations — the messages Haven sends around every stay: Instant Book and request-to-book confirmations, inquiries, co-guest invitations, guidebook, and more. Open one to edit what it says. You can't delete these or add new ones to this list.
Custom automations — your own automated messages to guests who have booked. Add as many as you like with New custom automation.

When to Add Your Own Booking Message

A check-in follow-up the day after arrival ("How's everything going?")
A door-code or parking reminder the morning they arrive
A local tips email a few days before check-in
A mid-stay offer for late checkout
A checkout-day reminder of your checkout tasks

How to Add a Booking Message

Step 1: Open Message automations

Go to Host Dashboard → Communication → Message automations.

Step 2: Click New custom automation

In the Custom automations section, click New custom automation.

Step 3: Choose when it sends

Pick what starts it:

Trigger	When it sends
Booking requested	When a guest sends a request to book
Booking confirmed	When a stay is confirmed (Instant Book or paid)
Before check-in	A number of days before arrival you choose
Check-in day	The morning the guest arrives
During the stay	A number of nights into the stay you choose
Check-out day	The day the guest leaves

To send one day after check-in, choose During the stay and set it to 1 night.

You can also limit a message to certain listings or to where the booking came from (for example, only direct bookings).

Step 4: Write the email and turn it on

Write the email in the editor, then turn the message on. It sends to every stay that matches from then on.

Good to Know

Any booking mode. Custom automations work the same for Instant Book and request-to-book listings. There isn't a separate "instant booking flow" to change. Add a message with the trigger you want.
Sent whatever the guest chose about marketing. Message automations go to guests with a booking, even if they unsubscribed from marketing, so keep them about the stay.
Only for bookings that still stand. Triggers like After check-out or Gone quiet are marketing and aren't offered here. Build those under Marketing → Campaigns → Automations.
PMS connected? If your PMS also emails guests, the Allow PMS automations on direct bookings row at the top of the page controls whether both send or only Haven does.
