Cosmo recommends campaigns to you, with reasons
Mid-week wellness retreat
Why now: spa bookings fall sharply through June while Tuesday–Thursday occupancy sits below target. A wellness package priced for loyalty members fills low-occupancy weekdays without discounting the weekend.
Win back the six-month lapsed
Why now: 2,105 guests in this portfolio have not stayed in six months or more, and the segment has never been worked with a dedicated offer. This is the largest untouched list on the property.
Corporate mid-week package
Why now: Tuesday–Thursday occupancy is running at 62%. Business travellers respond to mid-week packages with breakfast included, and this segment has not received a tailored offer this quarter.
Writes from your brand, not from the internet
Cosmo is based on a brand workspace you control. Upload the brand book, photo library, rate sheet, and booking URLs. Every campaign uses only that set.
- Property and brand context
- An image library that knows itself
- Real destinations
- Brand lock across the portfolio
Revision is a sentence, not a ticket
Every edit is a plain-English instruction. Cosmo executes, checks the result, and tells you what it changed. Six revision types keep your copy, tone, layout and subject line under full human control.
First draft
"Cut the body in half."
"More formal corporate rate audience."
"Switch to the stacked layout."
"New subject line under 50 characters."
Draft ready. Hero + cards layout, 890 recipients, subject line at 47 characters.
Segments your team already thinks in
Every guest on file
Consent status and suppression list applied before any send. No manual filtering required.
Three or more stays, or suite bookings
The list where a wrong send costs the most. Held to a higher approval standard by default.
Recent guests
Stayed inside the last quarter. Best response to re-engagement campaigns.
Loyalty members
Active programme members, matched to tier and point balance where available.
Lapsed guests
No stay in six months or more. The largest and most profitable re-engagement audience.
Business travellers
Corporate bookings and repeat mid-week stays. Price-sensitive to midweek incentives.
Bring your own list
Upload a CSV or Excel export and Cosmo creates a named segment from it, mapping the columns it finds into merge fields. Personalisation falls back gracefully when a field is missing — a blank first name never ships as “Hi ,”.
Sits behind your data, not beside it
Cosmo reads from the guest record Dextr already maintains across your PMS, CRS and call centre. No parallel marketing database to reconcile, and no second version of the truth about who a guest is.
Attribution that survives a finance review
Cosmo connects every campaign to the guests who received it, engaged with it, and ultimately booked, giving you a clear view of incremental revenue across every property.
- Per property, and rolled up
- Revenue, not proxies
- Unsubscribes count as a cost
- Exportable
The controls your risk team will ask about
Approval gate on every send
Cosmo cannot send. It can only ask. The request shows the final subject line and the resolved recipient count, and it waits for a named human role to approve.
Role-based authority
SAML 2.0 or OIDC single sign-on, with roles mapped from your identity provider's groups. Who can brief, who can edit and who can approve are three separate permissions.
Immutable audit trail
Every brief, draft, edit, layout change, approval and send is logged with actor and timestamp. Exportable for internal audit and for brand-compliance review.
Verified edits, not claimed ones
After every revision Cosmo checks the result against the instruction. If an edit did not land, it says so and offers to retry. It does not report success it cannot demonstrate.
Structural invariants
Unsubscribe link, preheader, sender identity and footer disclosures cannot be edited away. An edit that would break them is rolled back rather than shipped.
Undo, at any point
Every revision keeps the prior version. "Undo that" restores it exactly — including after a layout swap, and including after an edit that went the wrong way.
Secure by design
Dextr's agents follow your approved protocols, escalate uncertainties, and keep a full record to protect flagged properties.
Common questions from our customers
Per property, 7 days from kickoff to live: kickoff (day 1), knowledge upload (day 2), PMS + Stripe sync (day 3), AI calibration (day 5), go-live (day 7). For portfolios, we run waves of 3–5 properties in parallel — a 12-property group is fully live in roughly 6 weeks.
No. Dextr works alongside your existing PMS and tools. Your GMs update Dextr the way they'd brief a new hire — in plain English. No training required.
We support all PMS systems through direct integration or browser automation — Opera, OnQ, FOSSE, LightSpeed, Mews, Cloudbeds, and more.
We're following SOC 2 Type II and PCI DSS Level 1 standards. All data is encrypted at rest and in transit. We never store raw credit card numbers; tokenization is handled by your payment processor.
Our pricing is usage-based and depends on your workflows, property size, and usage volume. It's designed to maximize ROI by aligning cost with the operational value Dextr delivers.
We run a pilot on your toughest property first. If the numbers don't hold, you walk away — no lock-in, no penalty.
