The problem with your email marketing isn't the flows you set up. Those are fine. The problem is that between 85% and 95% of your store visitors are anonymous to Klaviyo or Perfit — no email attached, no profile identified — and so the flows never fire. Identifying more visitors can double the revenue your email automations generate.
How email flows work and why they go silent
Klaviyo and Perfit flows — abandoned cart, product browse, checkout started — have one requirement that almost nobody mentions in the tutorials: they only fire when the system knows who the visitor is. It's not enough for someone to add to cart or reach checkout. If Klaviyo doesn't have an email attached to that browser session, the event is logged but the flow never sends.
ESPs like Klaviyo and Perfit work with identified profiles: a profile has an email address, purchase history, and browsing history. An anonymous visitor has no profile. For Klaviyo, they don't exist.
When does a visitor become identified? When they subscribe, when they purchase, when they click a previous email, or when they fill out a form. That covers 5–15% of typical store traffic. The other 85–95% are invisible to your email tool.
How many emails are you failing to send right now?
If your store gets 10,000 unique visitors a month and 3% add to cart, that's 300 carts. If Klaviyo identifies only 15% of visitors, it sees just 45 of those 300 carts. The other 255 people added to cart or reached checkout, and never received an email. Their flows are configured correctly. They just never fire.
An abandoned cart email that doesn't arrive isn't a configuration problem. It's an identification problem. The flows every store needs are ready and waiting — they just never get the signal to send.
With vs without visitor identification: what changes
| Metric | Without identification pixel | With identification pixel |
|---|---|---|
| Identified visitors | 10–15% of traffic | 30–50% of traffic |
| Abandoned cart flows fired | Known subscribers only | All identified visitors |
| Browse abandonment flows | Minimal | Significantly higher |
| Revenue from email | Baseline | 2x (double) |
The only number that matters here is 2x: double the revenue from email. Not 10%, not 20%. Double. Because you're going from serving a small fraction of your audience to serving a significantly larger fraction, with the same flows you already have configured.
How server-side visitor identification works
Klaviyo and Perfit's standard browser pixel uses cookies to remember a visitor between sessions. When Safari deletes those cookies (in 7 days), when the visitor uses incognito mode, or when they arrive from a different device than the one they subscribed from, the pixel doesn't recognize them.
Server-side identification works differently: instead of relying on browser cookies, it uses the visitor's email as the identifier. When someone who's already on your list visits your store, the server-side pixel can recognize them even if they cleared cookies or are on a different device, because it cross-references the data against the profile already tied to their email.
That's what allows Klaviyo or Perfit to identify visitors that the browser pixel would have treated as anonymous. And every identified visitor is a potential recipient of your flows. For deeper context: why Klaviyo isn't tracking your visitors and how Perfit improves remarketing with visit identification.
Important: The Escalafy Pixel does not send emails or add contacts to your list. It works with the contacts that already exist in your Klaviyo or Perfit account: it identifies which of them are visiting your store right now, so flows fire for those people. The source of your profiles is always your own list. The pixel runs on Shopify and Tiendanube and is priced separately at /en/pricing/pixel — it is a separate product from the profitability dashboard.
Does it work on Tiendanube and Shopify?
Yes. The Escalafy Pixel for email has native integrations with Tiendanube and Shopify. Setup takes minutes from each platform. Once live, it starts identifying visitors who are already on your list but weren't being seen by the standard pixel.
If you use Klaviyo: the pixel sends browsing data from identified visitors directly to Klaviyo, where your existing flows fire automatically. No reconfiguration needed. How the pixel works with Klaviyo.
If you use Perfit: identified visitors enter Perfit's remarketing flows. How the pixel works with Perfit.
FAQs about visitor identification and email
Does the pixel add new contacts to Klaviyo or Perfit?
No. Escalafy's pixel does not create new profiles or purchase lists. It works with the contacts that already exist: it identifies which of them are visiting your store right now, so flows fire for those people.
What's the difference from Klaviyo's native pixel?
Klaviyo's native pixel uses browser cookies. When Safari clears them (in 7 days), when the visitor uses a different device, or when they browse incognito, Klaviyo sees them as anonymous. Escalafy's server-side pixel can identify them using the email as a cross-reference against the existing profile.
Do I need to reconfigure my email flows?
No. Your existing abandoned cart, product browse, and checkout flows fire automatically for the visitors the pixel identifies. The pixel doesn't change your automation logic — it expands the audience that triggers it.
Is the email pixel the same as the Meta Ads pixel?
Escalafy's Pixel has two functions: it improves conversion tracking for Meta Ads (raises EMQ) and also identifies visitors for your email flows. Both functions live in the same product, priced at /en/pricing/pixel.
How much traffic does it take to make it worthwhile?
The more traffic you have and the larger your email list, the higher the impact. If you have 5,000 visitors/month and 3,000 Klaviyo contacts, the pixel can recognize a meaningful share of that traffic as known contacts. With fewer than 1,000 visits/month, the impact is lower.
Double your email revenue
Escalafy's server-side pixel identifies list visitors that the standard pixel misses. Your Klaviyo or Perfit flows fire for twice as many people. Without changing a single automation.
