Posty Signal

Your store knows more than it tells you.

Signal connects what shoppers do, who they are and what they buy, so you can see what sets your best customers apart and turn it into Klaviyo audiences that stay current.

Built on the data you already have.

Illustrative data from a sample store.

01The gap

Your customer lives in four tabs.

Orders sit in Shopify. Sessions sit in analytics. Audiences sit in Klaviyo. Whatever you know about who people are sits in a spreadsheet nobody has opened since the last planning cycle. One good question costs three exports and an afternoon, and the answer is stale before it reaches a campaign.

Connect once. Signal keeps up.

Connect your store and Signal imports the order history available to it, then keeps it updated alongside on-site behavior and enrichment. You always see import progress, the last successful update and any errors. Retries never create a duplicate order, event or profile.

02How it works

Current, potential, action.

One loop, from what the data says to an audience you can use. Signal shows its working at every step.

01
Current
What the data says.

Every visitor and customer in one connected view: orders, behavior, acquisition and enrichment. Each field keeps its source and timestamp, so you always know what you're looking at.

02
Potential
What is worth testing.

Patterns and relationships, surfaced only when the data supports them. Each one comes with its definition, its sample size and the reason it might matter.

03
Action
What you do about it.

Turn a finding into a living cohort and keep it current in Klaviyo as people join and leave. No exports, no stale lists.

03Profiles

One profile, from first visit to fifth order.

Every eligible visitor starts with a behavioral profile, before you know their name. When a reliable, permitted identifier turns up, like a sign-up or an order, Signal connects their earlier activity to the customer record. It never merges two people on a weak clue like a shared IP address.

  • Orders, products, spend, discounts and returns
  • Page views, searches, carts and available session replays
  • First and latest touchpoint, with UTMs kept per session
  • Lifetime spend, order value, frequency and time between orders
  • Custom and calculated fields, added without a rebuild

In plain words

Customers who have spent $800 or more, haven't ordered in 90 days and are buying less often than before. Anyone who started a return in the last 30 days is left out.

642match+0 vs saved

Audiences that update themselves.

Combine conditions, exclusions, date windows and event counts. Before you save, Signal shows the rule in plain words, how many people match and a sample of who they are. After that, people enter and leave as their behavior changes, including when a time window runs out.

Edit, pause or archive any cohort. Each one shows when it was last evaluated.

Suggested, when your data supports them
Big spenders, slowing down

Lifetime spend in your top 10%, purchase frequency falling.

Why it may matter: a check-in before they lapse.

Browsing, not buying

Viewed one category three or more times without a purchase.

Why it may matter: interest you can see before a first order.

From one campaign to repeat

Came from one campaign, bought one product, then came back for more.

Why it may matter: shows which campaigns find repeat buyers.

05Klaviyo

Kept current in Klaviyo.

Switch on sync for any saved cohort. Signal adds people as they qualify and removes them when they stop, then shows you the last successful sync, any errors and anyone it couldn't match.

A cohort never grants marketing consent or lifts a suppression. Klaviyo's rules still decide who hears from you.

06Ask

Ask your store a question. Get the working too.

Ask in plain English, in Signal or from your own AI tools through a permission-controlled MCP connection. Both use the same definitions and the same store-level access. Every answer names its population, timeframe, sample size, comparison group, sources and limits, and opens onto the records behind it.

Correlation is labeled as correlation.
Upside is shown as a scenario, never a forecast.
Stale or incomplete data is flagged, not hidden.
07Your data

Every number shows where it came from.

Signal keeps the habits of a finance tool: sources kept, states labeled, nothing filled in quietly. It shows what it can see, and coverage depends on what each shopper permits. It never claims to identify every visitor.

01
Source and timestamp on every field

Each value keeps where it came from, when it arrived and how it is defined.

02
Known, inferred, missing, conflicting

Four states, always labeled. A missing value is never shown as a zero.

03
Enrichment, marked as enrichment

Third-party attributes carry their provider and refresh date, and modeled estimates say so. Signal never fills a gap with a guess.

04
Consent comes first

Capture and replay follow each shopper's consent settings. Sensitive fields are masked, with retention and deletion built in.

05
No card data

Payment method descriptors only. Never full card numbers, security codes or credentials.

06
Your store, and only yours

Store-level isolation and access controls, in the app and over MCP.

Find the pattern. Build the audience. Keep it current.
