How long does it take to enrich Klaviyo with household data?

Around 10 minutes for the connection and segment selection. Outra resolves to households and writes attributes back to the profile in the background. Typically minutes for a small list, hours for a large one.

Do I need engineering help to enrich Klaviyo profiles?

No. The integration is OAuth-based. You authorise Outra to read profiles and write back custom properties. No SDKs, no schema changes, no warehouse.

What attributes get written back to each Klaviyo profile?

Family stage, Occupancy status, Property type, Bedrooms, Property value band, Purchasing power band and Move stage. Appearing as standard custom properties you can use in any segment or flow.

Add Household Intelligence to Klaviyo Fast

In short

Connecting Klaviyo to Outra takes about 10 minutes and no engineering. You authorise Klaviyo via OAuth, pick a segment to enrich, and Outra writes seven household attributes back to each profile as standard Klaviyo custom properties: family stage, occupancy status, property type, bedrooms, property value band, purchasing power band and move stage. They appear in the segment builder immediately and work in flows, campaigns and Custom Audience syncs like any native property.

What you'll have at the end of 10 minutes

Every active Klaviyo profile in your selected segment will carry these new custom properties. The property names below are the exact strings you'll see in Klaviyo's segment builder dropdown:

Household properties written to each Klaviyo profile, with the values you can segment on.
Klaviyo property	Example values	What it's good for
`Family stage`	Pre-school children, Bigger Families, Established Professionals, Empty Nest	Product recommendation, tone, bundle size
`Occupancy status`	Owner-Occupied, Privately Rented, Social Rented	Anything fitted, installed or permanent
`Property type`	Detached, Semi-detached, Terraced, Flat	Garden, outdoor, large-format goods
`Bedrooms`	1, 2, 3, 4, 5+	Quantity and room-count logic
`Property value band`	Banded, low to high	Price-tier and premium-range routing
`Purchasing power band`	Low, Medium, High, Ultra-High	Discount suppression, VIP routing
`Move stage`	Settled, Move intent, Moving, Just moved, Recently Moved, Sale anniversary	Timing-led triggers and urgency

Every segment, flow and Custom Audience in your account can reference them immediately. No schema changes; no warehouse; no engineering ticket.

Before you start

You need Klaviyo admin (or owner) access to authorise the integration
You need an Outra account. Start a free trial at outra.co.uk if you don't already
You need to know which Klaviyo segment you want to enrich first (most brands start with "engaged in last 90 days")

The 5 steps

Step 1, Connect Klaviyo (~2 minutes)

Inside Outra, choose Connect Klaviyo. You'll be redirected to Klaviyo's standard OAuth screen. The same one any approved integration uses. Authorise read access to profiles and write access to custom properties. No SDKs, no API keys to manage.

Step 2. Pick the segment to enrich (~1 minute)

Choose the Klaviyo segment Outra should enrich. We recommend "Engaged in last 90 days" for the first run. It gives you fastest impact on flows and campaigns without burning enrichment on lapsed profiles.

Step 3. Resolve to households (background, ~minutes to hours)

Outra hashes each profile, matches against the UK household graph (30M+ addresses), and builds a household identifier per profile. You don't need to do anything during this step.

Step 4, Append attributes (background, automatic)

Family stage, Occupancy status, Property type, Bedrooms, Property value band, Purchasing power band and Move stage are written back to the Klaviyo profile as standard custom properties.

Step 5. Build your first segment (~3 minutes)

Open Klaviyo's segment builder. The new properties appear in the dropdown alongside everything else. Build your first segment, e.g. "High Purchasing Power AND engaged in last 30 days", and use it in a flow or campaign.

What to ship first

Branch your welcome flow on Move stage = "Just moved" / "Recently Moved"
Add a suppression rule: exclude High Purchasing Power households from your default discount sequence
Sync your top-RFM × High Purchasing Power segment to Meta as a Custom Audience seed

Worked example: the three segments to build in your first session

Klaviyo segment definitions, written exactly as you'd assemble them in the segment builder (Definition → Properties about someone):

Just-moved buyers. Move stage equals Just moved OR Recently Moved AND Occupancy status equals Owner-Occupied. Use it as the entry filter on a welcome-flow branch — the copy can reference setting up a new home without guessing.
Discount-suppression list. Purchasing power band equals High OR Ultra-High AND Property value band is one of your top two bands. Add this as a flow filter set to exclude on your default welcome-discount email. You stop handing margin to the households least likely to need it.
Meta seed segment. Purchasing power band equals High OR Ultra-High AND Placed Order at least 2 times over all time. Push it to Meta via Klaviyo's native Meta integration — this becomes the Custom Audience seed, not your full list.

Order matters: build segment 2 before you touch the welcome flow, or your next send goes out with the old discount logic still live.

Each is covered in detail in 5 Klaviyo flows you can't build without household data.

Common questions before you click connect

Will this slow Klaviyo down?

No. Custom properties are a native Klaviyo concept; we write to them the same way Klaviyo writes its own predictive properties.

What happens to profiles we can't match?

Unmatched profiles are left untouched. No partial data; no fake values. Match rates are typically 70–90% of UK profiles for D2C lists.

Can we remove the data?

Yes. Disconnect Outra and the custom properties remain on the profile but stop updating. Or trigger a deletion job to remove them entirely.

The bottom line

Most "enrichment" projects stall at the engineering cost. This one shouldn't. It's an OAuth click, a segment selection, and a wait. The hard work is what you do after the data lands: branching flows, sharper Custom Audiences, smarter suppression. That's where the revenue moves.
