Conditions let you add logic to your automations. Instead of sending the same message to every guest, you can check for specific criteria and take different actions depending on the result.
Every condition has two paths: true (the condition passes) and false (it doesn't). You connect different actions to each path in the automation builder.
Some conditions require a PMS connection. Stay & Reservation, Room (Space) Status, Payment & Billing, Identity & Compliance, Booking Channel, Booking Source, and Reservation Date conditions read from your PMS in real time — they only appear in the condition menu if your account is connected to a PMS (Mews today). Workflows that use them show a "Needs PMS" badge until a PMS is connected.
Checks whether the guest has specific tags on their profile.
Add one or more tags to check for, then choose how they're matched:
Any (default) — passes if the guest has at least one of the listed tags
All — passes only if the guest has every tag listed
Check if the guest has a "VIP" tag. If true, send a personalized welcome message. If false, send the standard message.
Checks whether the guest's profile has specific information filled in. Select one or more fields to check:
Has Phone — guest has a phone number on file
Has Email — guest has an email address on file
Has First Name — guest has a first name on file
Has Last Name — guest has a last name on file
Has Address — guest has an address on file in your PMS
Is Repeat Guest — guest has more than one reservation on record
When you select multiple fields, use the Any/All toggle:
Any — passes if at least one selected field is true
All — passes only if every selected field is true
Before sending an SMS, check if the guest has a phone number. Route the true path to "Send SMS" and the false path to "Send Email" (or skip the action entirely).
Checks the current status of the guest's reservation. Options include:
Checked In — the guest's reservation is active (Started status)
Not Checked In — the guest's reservation is not active
Status matches — the reservation matches a specific status (Confirmed, Enquired, Started, Processed, Canceled)
Trigger on "Checking in today" via a scheduled automation, then add a Stay & Reservation condition to verify the guest is still in Confirmed status before sending a pre-arrival message. This prevents sending the message to guests who were checked in early.
Simple yes/no checks for whether the guest has a phone number or email address on file. These are standalone condition types that do the same thing as the matching fields in Guest Profile — use whichever is more convenient for your workflow.
Checks whether the guest is currently checked in — meaning they have an active stay with a check-in recorded and no check-out yet. This is a more specific check than Stay & Reservation's "Checked In" because it verifies the actual check-in event, not just the reservation status.
Checks payment and billing status tied to the guest's current reservation — not their overall account. This is pulled from your PMS in real time. Select one or more fields:
Has Card on File — guest has an active credit card in your PMS
Has Pre-Authorization — a pre-authorization hold exists for this reservation
Balance Is Zero — this reservation's balance is fully paid
Balance Is Not Zero — this reservation has an outstanding balance
Use the Any/All toggle when selecting multiple fields.
Good to know: These checks are scoped to the reservation associated with the automation's trigger — not the guest's total account across all stays. For example, "Balance Is Zero" checks whether this reservation is paid, not whether the guest has a zero balance overall.
Before sending a check-in link, verify the guest has a card on file and a pre-authorization for this stay. If not, send a payment reminder instead.
Checks guest identity and compliance data from your PMS in real time.
Has Uploaded Documents — guest has identity documents on file in your PMS. This checks that documents have been uploaded — it does not verify their validity or completeness.
Has Marketing Consent — guest has opted in to marketing communications in your PMS.
Use the Any/All toggle when selecting multiple fields.
Before sending a marketing follow-up after checkout, check if the guest has given marketing consent. Only send the message on the true path.
Checks the broad category the reservation came in through.
Direct — booked directly (phone, walk-in, your own booking engine via Mews's Distributor origin)
Booking Engine — booked via Mews Booking Engine
OTA — booked via a channel manager (Booking.com, Airbnb, Expedia, Vrbo, etc.)
Send a different welcome message to OTA guests (who haven't given you their email yet) than to direct bookers (whom you can warmly thank for booking direct).
Checks the specific source the reservation came from. Use this when you need finer granularity than Booking Channel — for example, when "all OTAs" isn't enough and you want to target Airbnb guests specifically.
Known channels — a built-in catalog of the major OTAs (Booking.com, Airbnb, Expedia, Vrbo, Hotels.com, Agoda). Pick one or more.
Other sources — pull from a live list of source names in your reservation data, so you can target phone bookings, email bookings, or smaller channel managers by their exact source name in Mews.
Use the any/none match toggle to either require a matching source or exclude one.
Send Airbnb guests an extra message reminding them to use your direct site next time, with a discount code — but exclude Booking.com guests, who have stricter OTA rules about steering.
Checks how the reservation lines up against today's date.
Reservation started N days ago — passes if the guest's check-in date was exactly N days ago. Useful for "follow up two days after check-in" or "mid-stay touchpoint on day 3" automations.
Pair a daily Scheduled trigger with Reservation started 2 days ago to send a "how's your stay going?" message every guest gets on day 3 of their stay.
Checks the current status of the guest's room. In Mews, rooms are called "spaces" — that's the term you'll see here. Status values come from your PMS in real time.
Common statuses include:
Clean — the room is ready for the next guest
Dirty — the room needs to be cleaned
Inspected — the room has passed inspection and is ready
Out of order — the room is not currently available
For an automated check-in message, add a room status condition that only sends the door code if the space is Clean or Inspected. If the room isn't ready, route the false path to alert your team.
Checks the current day or time when the automation runs. Use this to scope automations to business hours, weekdays, weekends, or specific times of day.
Day of week — pick one or more days (Monday through Sunday)
Time of day — pick a window (e.g., between 9 AM and 5 PM)
For a workflow that sends automated SMS, add a time-of-day condition that only sends between 8 AM and 9 PM in the guest's local time. Texts sent at 3 AM tend to wake people up.
Stack conditions for precision. You can add multiple conditions in sequence — for example, first check if the guest has a phone number, then check if they're a repeat guest, and only then send a VIP SMS.
Use the false path. Don't just ignore it — route it to an alternative action. If a guest doesn't have a phone number, maybe send an email instead.
Conditions are evaluated in real time. The check happens when the automation reaches that step, not when the trigger fires. If a guest's profile is updated between the trigger and the condition, the condition uses the latest data.
