THE PROBLEM
Most of your visitors leave without a name.
Only a small share of visitors ever fill out a form. Analytics tells you what the rest did, but not who they are. Cookies follow a browser, IP lookups name a network, and your best prospects slip away unseen.
THE GUESTBOOK COHORT DIFFERENCE
The person, not just the company.
One lightweight tag matches visitors against a national identity graph using deterministic matching. If the signals aren’t strong enough, we don’t guess. You only get high-confidence matches.

Analytics shows what they did. Guestbook shows who they are.

HOW IT WORKS
Three steps. Visitors the same day.
01
Open the guestbook
We add one small tag to your website, the same way you’d install Google Analytics or the Meta Pixel. Scope it to the pages that matter.
02
Visitors sign in
Each visit is matched to a real person, and identified visitors arrive in your account every hour.
03
Start the journey
We segment visitors by intent and behavior, then feed them into Compass, Postmark, and Passport Cohorts.
What you can do with your guestbook.
Direct mail
Send a postcard to visitors who scroll past digital ads, through Postmark Cohort.
Email follow-up
Reach visitors who viewed a product or left a cart, while they’re still interested.
Ads and streaming TV
Retarget identified visitors on Meta, Google, TikTok, and connected TV.
Stop paying twice
Suppress existing customers from prospecting campaigns so budget goes to new buyers.
PRIVACY BUILT IN
Responsible by design.
- Consent-based U.S. data only. No third-party cookies required.
- You stay the data controller. No visitor data is sold to make a match.
- We help you update your privacy policy and set up opt-out tools during onboarding.
