Personalization events in Amplitude, Amplitude cohorts in Personyze

Name: Amplitude cohorts as audiences: personalize for a cohort
Uploaded: 2026-09-26
Duration: 1 min 45 s
Description: Set up in the panel — a cohort synced from Amplitude, the audience list it becomes, and a home-page headline rewritten for the customers in it. Then do it with your own cohorts.

Every campaign a person matches, clicks or converts on can be an Amplitude event — named by you, carrying value and currency — sent from Personyze’s servers with no SDK on the page. Cohort, funnel and retention analysis on what personalization actually did — and your Amplitude cohorts come back as audiences any campaign can target.

The event name is the one you type. Value and currency ride along, so the tool can chart what a match was worth.

Why it matters

Personalization is a variable. Put it in the analysis.

Your product analytics know what users do; they do not know which experience Personyze showed them. Sending the match as an event closes that gap: a cohort of people who saw the cart-recovery offer, a funnel that starts at a matched audience, retention by campaign.

The events go server-side, so they arrive whether or not Amplitude’s script loaded on the page, and whether or not the visitor is still on the site — scheduled email campaigns included.

What you can do

What Amplitude + Personyze unlocks

Cohorts by campaign

The people who matched an audience or clicked an action become a cohort in Amplitude, ready for retention and behavioural comparison.

Funnels that start at a match

Chart what happens after the personalization: from matched, to clicked, to the goal your campaign was aimed at.

Value on the event

A match can carry a value and currency — a number or any visitor column — so revenue-weighted analysis works out of the box.

Server-side, no SDK

Sent from Personyze’s servers with your project API key. Nothing to add to the page, and nothing lost when a script is blocked.

The other direction

Your Amplitude cohorts, as Personyze audiences

Personyze works both ways with Amplitude: campaign events go into your product analytics, and your Amplitude cohorts come back as Personyze audiences. Build a cohort such as “trial users who never invited a teammate”, sync it, and show those people a different homepage, onboarding banner or offer. Membership stays in step automatically — when people join or leave the cohort, they join or leave the audience list, and the website sees it on their next page.

Take the webhook URL and a keyIn Personyze, open Settings → Integrations → Amplitude, take the webhook URL and generate a Personyze API key.

Add a Cohort Webhook in AmplitudeEnter the URL, and add an Authorization header with the value Bearer followed by your key.

Sync a cohortIt arrives as the audience list “Amplitude: <cohort name>”, ready for any website, email or offline campaign.

People are matched by Amplitude’s user_id against the user ID your site sends to Personyze when people sign in — and by email when the user_id is an email address. Cohort webhook destinations are part of Amplitude’s paid plans.

FAQ

Common questions

Do I need the Amplitude SDK on my site?

No. Events are sent from Personyze’s servers with your project API key. That also means they arrive when a script blocker stops the SDK, or when the campaign was an email sent while the visitor was not on the site.

Nothing is arriving and there is no error. Why?

Almost always the project is in the EU and the EU project switch is off. An EU key used against the US endpoint is accepted and the data is dropped, silently. Tick the switch on the Amplitude card.

Which campaigns can send?

Email & SMS Personalization and Cart Abandonment Emails on their scheduled pass, and Targeting and Personalization, A/B Testing, CRM / User-List Targeting and Landing Page campaigns within about a minute of a match.

Is anything read back from Amplitude?

Yes — cohorts. Sync an Amplitude cohort to Personyze’s webhook and it becomes an audience list named “Amplitude: <cohort name>”, kept in step as people enter and leave the cohort, and targetable in any campaign.

Which Amplitude plan do I need for cohorts?

One that includes cohort webhook destinations — a paid Amplitude plan. Sending events to Amplitude works on any plan.
