CartStack for hotels and resorts

Bring back the guests who almost booked direct.

Most travelers who price out a stay never come back on their own — and when they do, it is often through an OTA. CartStack follows up — email, SMS and push — with the exact stay they left behind, and brings a real share of them back to book direct. Live on any booking engine in about 15 minutes.

Recovering direct booking revenue for hotels, resorts and vacation rentals

Every exit, not just payment

A thousand travelers search. Twenty book.

The other 980 leave somewhere between the home page and the payment form. Most tools only notice the ones who reached payment. CartStack recovers from every exit — and sends them back to your booking engine, not the OTA.

Recover

Recovery starts the second they leave your booking engine.

Whether they left from a room page, a priced-out stay or a half-finished reservation, Recover picks it up and follows through — the right message, the right channel, the right moment — until they book or the sequence ends. It works for every guest who identifies themselves along the way — and with real-time capture, that happens the moment they type.

Dynamic personalization

The room, dates and rate they priced go straight into the email.

The room, dates, rate and add-ons they priced drop into every message. A default sequence ships ready to send — change the timing, drop in your property's branding, and it's yours.

Sends from your property's domain, in your voice The series stops the moment they book Runs beside your CRM and CRS — it only handles recovery

Real-time email capture

The moment a guest types an email anywhere on your site — booking engine, newsletter, special offers — Recover has a contact to follow up with, even if they never hit submit. Anyone who self-identifies is covered.

Conditional content

Set a rule, and the offer changes with the booking.

Every message already writes itself around the room, dates and rate. Conditional content goes a step further — set a rule, and the email changes with the booking. A 6-night stay earns an offer. A 3-night stay doesn't, and you keep the margin.

Does the heavy lifting

Email

Where the whole story fits — the room, the dates and the rate they priced, in your voice, from your domain. This is the channel that recovers most of the revenue.

A shorter, faster nudge

SMS

One line of text with a deep link straight back to their dates and room. Its own sequence, its own timing, triggered by the same abandonment.

No email or phone? No problem

Browser push

The backstop for guests who never handed over a single contact detail — a permission-based nudge straight to their browser.

Reveal

Know who's abandoning — even when they never enter an email.

Recover follows up with everyone who types an email. Reveal is for the rest — the travelers who check rates, pick a room and leave without ever identifying themselves. It resolves those anonymous visitors into identified contacts, ready for Recover to follow up or for your reservations team to work by hand.

Retain

Capture more guest emails before they leave.

An on-site messaging toolkit — exit-intent offers, Send my stay, conversion nudges and tab alerts — that asks for the email earlier and keeps more travelers in your booking engine. Every address it captures is one more guest Recover can follow up with.

Recover, with Reveal and Retain

Recover does the recovering. Reveal and Retain hand it more guests.

On its own, Recover follows up with every guest who identifies themselves — from any exit, the moment they type. Reveal and Retain widen that pool with the travelers who never would have, so the same engine has more people to bring back to book direct.

$1.15M in direct booking revenue recovered in 30 days.

A global hotel group ran cart and browse abandonment recovery across dozens of hotel brands. Recovery started from every exit, not just payment — and the direct share moved.

Where the recovered revenue started

Browse abandonment $291K
Booking abandonment $612K
Payment abandonment $247K

Recovery had only ever run at payment. Starting it from the room and rate pages — where most guests leave — is where the direct number moved.

Plug and play

What's booking abandonment costing your property?

Rooms, ADR and monthly direct bookings — see how much direct revenue you could be recovering.

Why CartStack

Built to do one thing better than anyone else.

CRMs and booking engines include recovery the way airlines include food. CartStack is the recovery layer — and it runs beside whatever you already use.

01

Recovery from every exit

Browse, rate-search and booking abandonment, all on one install. Most tools only wake up at the payment step.

02

Attribution you can trust

Only engaged bookings count. If a guest never opened or clicked a recovery message, we don't take credit for the reservation.

03

Set it and forget it

A weekly report lands in your inbox with what recovered and what's trending. Your revenue team or agency keeps the reins; we handle the recovery layer.
