Retention.com sends every identified visitor to your Klaviyo account. Untitled identifies them, enriches them with 100+ attributes, segments them by behavior, and activates them across email, paid social, CTV, and direct mail. Same starting point. Very different ending.
Identification is the easy part. What makes a visitor identification tool actually generate revenue for your company or agency is everything that happens between the visitor being resolved and revenue showing up in your reports. Here's where the gap is widest.
Retention.com: sends every identified visitor to Klaviyo. Their fix for the deliverability fallout is a manually maintained "Do Not Email" audience that excludes people who didn't engage with the first email, even if those people come back to buy later.
Untitled: build dynamic audiences by behavior, demographics, intent, pages visited, and your very own first-party data before anything syncs. Last page visited, referrer, page depth, purchase history, all available. No SQL required and no maintaining a exclusion audience (unless you really want to).
Retention.com: Klaviyo is the integration. Everything else requires you to export and load somewhere yourself, though they claim other integrations.
Untitled: sync the same audiences to Klaviyo, HubSpot, Meta Ads, Google Ads, the Untitled CTV DSP, and direct mail postcards within 24–48 hours. One identified visitor can fuel five channels in the same workflow.
Retention.com: waits for someone to land on your site. If they never come, you'll never know. No intent data, just ONE visitor identification feature.
Untitled: 36,000+ contextual intent topics built from REAL browsing behavior across 300,000+ publisher sites. Build audiences of in-market buyers before they ever visit, then identify them on-site when they do.

"With the Untitled ID Tag, we identified over 2,000 hidden shoppers on our website in the first two days. We turned these into paying customers through Klaviyo. The ROI was insane."
"Untitled boosted our online conversion rates by a remarkable 21%. It stands out with its user-friendly interface and actionable customer data. We highly recommend it."
"Since incorporating Untitled into our digital strategy, we've seen remarkable results — a testament to its effectiveness in converting browsers to buyers."
Most brands that switch from Retention.com to Untitled aren't unhappy with identification: they're unhappy with the lack of supporting features within Retention. Here's how the day-to-day actually changes.
Yes — natively. Klaviyo is one of our core integrations, alongside Mailchimp, Meta Ads, Google Ads, Shopify, HubSpot, and Salesforce. The difference isn't whether you can send identified visitors to Klaviyo; it's that you can segment and enrich them first, send the right ones, and run the same audiences in four other channels without exporting CSVs.
Two reasons. First, our identity graph — 300M+ people-based records — is built from a wider set of first- and second-party data sources, not gated to any single signal type. Second, our matching is deterministic and tuned for high-fidelity person resolution rather than maximum-volume identification.
In practice: Toadfish identified 60% of their site traffic on Untitled. Industry-typical match rates for the Retention.com category cap around 40%.
Yes. We operate within US privacy frameworks using a first- and second-party data model. We don't collect PII directly — matches happen through secure deterministic processes against our identity graph. Compliance on your side requires a disclosed privacy policy, a consent management platform, and honoring opt-out signals.
Our compliance posture is documented and we resolve US-based visitors only.
Setup is about 15 minutes. You install the Untitled ID Tag on your site, connect your Klaviyo (and Meta, Google, Shopify, HubSpot — whichever you use), and start segmenting and activating from day one. Historical data from connected integrations syncs on initial connection.
Our team handles the configuration with you, and you can run both tools in parallel during the trial to compare match rates and outcomes directly.
