The Hidden Cost of Anonymous Visitor Identity Tools
If you’re using a visitor ID tool to recognize anonymous traffic and sync it to Klaviyo…
You might think you’re being clever.
But behind the scenes, you’re actually:
Hosting and sending to useless contacts who will never convert. Conversion rates on anonymous contacts are .00001%.
Negative engagements, silent spam complaints, and phantom clicks. Spam rates are 50 to 100x higher.
Polluting your most profitable revenue channel with low-quality contacts.
Bloated Lists Don't Convert
Let’s break it down.
Third-party data providers are adding thousands of "leads" who never opted in.
These leads never open, never click, and never buy.
You still pay Klaviyo every month to email them, both in profiles and sends.
They hurt deliverability for your actual customers, which impacts revenue.
Every contact added by a shady enrichment tool is a landmine sitting in your flows, silently killing inbox placement for the people who DO want to hear from you.
A Better Way:
First-Party+
CustomersAI gives you real-time, server-side behavioral signals of profiles in your database which are, compliant, accurate, and convert.
No fake opens.
No spam traps.
No guessing games.
Our First-Party+ approach delivers:
Real signals from actual visitors
Trained on your best customers' behavior
No fake contacts inflating your bill
Real LTV growth from quality contacts
This isn’t enrichment.
This is enhancement.

What Customers Say
“After getting rid of the ghosts from Opensend and switching to First-Party+, our flows hit harder, inbox placement improved, and we cut our Klaviyo bill by 30%.”
Jeff Herdman
CEO & Founder, DFND
CEO, Haverhill
“Watching our email performance decline with Revenue Roll was incredibly frustrating, but we didn’t realize how much poor data was to blame. CustomersAI turned that around almost overnight with no changes to our flows, just better data”
