SiteMinder’s Guest Engagement lets you send automated pre-arrival emails, which is exactly what you need to deliver your registration link. Best Guest connects in two ways:

  • Automated messages — SiteMinder Guest Engagement / booking-engine guest emails deliver your registration link before arrival.
  • iCal sync — Best Guest imports your SiteMinder reservations.

Estimated setup time: 5–10 minutes.

Before you start

  • A SiteMinder account with Guest Engagement (or booking-engine guest emails) available
  • A Best Guest account
  • Your Best Guest registration link, e.g.
https://bestguest.app/l/your-listing?channel=siteminder

(Use your real link. ?channel=siteminder records the reservation origin.)

Using the right link: every listing — each apartment, room, tent, RV, or whatever counts as your smallest bookable unit — has its own unique registration link. If you manage more than one listing, double-check you’re copying the correct one. Find all your links in Best Guest under Properties → [property] → Listings → Copy listing link, or grab them during the Listings step of onboarding.

Path 1 — Automated pre-arrival email

  1. Go to Guest Engagement → Communication → Scheduled messages and create a new Pre-stay message named “Best Guest Registration”.
  2. Add your registration message under Email design, and insert SiteMinder’s guest-name placeholder from the editor.
  3. Under Sending rules, use the slider to set how many days before arrival it sends (0–30 days), e.g. 2–3 days.
  4. Check Segmentation — SiteMinder currently only lets you filter by direct-vs-OTA bookings, not by a specific channel, so this will be one message covering all guests rather than something you can target per OTA.
Dear (guest name),

Before you arrive, please complete your quick online check-in:
https://bestguest.app/l/your-listing

It takes under 2 minutes. We look forward to welcoming you.

SiteMinder lets you customise the timing for each stage of the guest journey (before arrival, at check-in, during the stay, after departure).

Best Guest automatically reminds the main guest if they started registration but haven’t finished it. If a guest never opens the form at all, though, that reminder can’t reach them — so it’s worth scheduling a second pre-arrival email, timed 1 day after arrival instead of before it, using only the link:

Hello (guest name),

Everything alright? Did you fill out all your forms and is the data correct?
Please follow this link if you still need to add/change some information:
https://bestguest.app/l/your-listing

Path 2 — iCal sync

SiteMinder doesn’t publicly document a dedicated iCal or calendar-export feature, so treat this path as unconfirmed. To import SiteMinder reservations into Best Guest’s Reservation Verification, check your account’s Guest Engagement or channel/distribution settings for a calendar-export or iCal option — exact wording may vary — or sync instead from the OTA or PMS that SiteMinder distributes your reservations to, and paste whichever link you find into Best Guest.

  • Reservation confirmed → confirmation only
  • 2–3 days before arrival → registration link
  • Arrival day → access instructions
  • 1 day after arrival → reminder for guests who haven’t completed registration
  • Departure → thank-you

Troubleshooting

Email didn’t send — confirm the pre-arrival email is enabled, the timing, and that a guest email address is present on the reservation.

Reservation missing in Best Guest — verify the URL and ?channel=siteminder.

Frequently asked questions

Can I time messages differently across the guest journey?

Yes — SiteMinder lets you customise timing for each stage (before arrival, at check-in, during the stay, after departure), so the registration email doesn't need to be the only automated touchpoint.

What should I check if a pre-arrival email doesn't send?

Confirm the pre-arrival email is enabled, check the timing configuration, and verify a guest email address is actually present on the reservation.
