Meta wins the first sale. Klaviyo makes it worth it.
Paid gets the customer; owned keeps them. Patricia reads both so you judge acquisition on lifetime value, not the first order, and stop paying to prospect people who just bought.
@Pati our Meta CAC crept up to $48 this month and the customer is nervous. Is that actually bad given what Klaviyo is doing on the back end?
It looks worse than it is, but there is real waste to cut. Joining Meta acquisition with Klaviyo lifetime value:
- $48 new-customer CAC, but 90-day LTV from Klaviyo repeat purchases is $141, so CAC to LTV is about 1 to 2.9, healthy
- The post-purchase flow is doing the heavy lifting: second-order rate is 31% and climbing
- Waste to fix: the prospecting ad set does not exclude recent buyers, and Klaviyo counts 2,300 purchasers in the last 30 days that prospecting can still pay to reach
- The prospecting ads promise 15% off, but the welcome flow opens with free shipping, so new buyers meet a different offer than the ad sold them
Good. Keep recent buyers out of prospecting. Show me before it goes live.
Staged, nothing applied: a website custom audience of everyone who purchased in the last 30 days, built from the Meta pixel's purchase event, and an exclusion of it on the prospecting ad set. Both wait for your yes. It comes from the pixel, so no customer emails leave Klaviyo. For the offer mismatch, I drafted a welcome email that leads with the 15% off, here for your review.

What Meta Ads and Klaviyo do together.
Each is useful alone. Joined, they answer the question neither can on its own.
Judge Meta CAC against real Klaviyo LTV, not the first order
A $48 CAC is a different story at a $141 lifetime value. She joins Meta new-customer cost with the repeat-purchase revenue Klaviyo drives, so acquisition is graded on blended CAC to LTV instead of the first sale alone.
Keep recent buyers out of Meta prospecting with a website audience
Prospecting to people who just bought is wasted spend, and the retention flows should own them anyway. She builds a website custom audience of recent purchasers from the Meta pixel and excludes it from prospecting, by default after your yes. Klaviyo's purchase count shows how big that pool is.
Make the ad's promise and the welcome flow match
A new buyer who clicked a 15% off ad and gets a free-shipping welcome email feels the seam. She reads the live Meta ad copy next to the Klaviyo welcome flow and flags where the offer or the voice drifts apart.
Lift repeat rate with post-purchase flows so a mediocre CAC still pays
Acquisition that breaks even on the first order wins on the second. She watches the post-purchase and winback flows in Klaviyo against Meta's new-customer volume, so you know retention is turning fresh buyers into repeat revenue.
Report acquisition and retention as one funnel, not two dashboards
Meta spend, new-customer CAC, and creative on one side; Klaviyo flow revenue, repeat rate, and LTV on the other, in one weekly answer, so the customer sees the full customer economics instead of paid and email reported apart.

Ask
Mention @Pati with the question. She reads both sides at once; by default, building an audience or changing an ad waits for your yes, and sending an email always does.

FAQ
Meta Ads + Klaviyo, answered.
What does connecting Meta Ads and Klaviyo together let Patricia do?
She reads spend, new-customer cost, and ads from Meta Ads and joins them to lifetime value, segments, and flow revenue in Klaviyo. That gives you blended CAC to LTV, keeps recent buyers out of prospecting, flags where the ad and the welcome flow disagree, and shows whether retention flows are lifting repeat rate. Neither tool answers that alone.
How does she keep recent buyers out of prospecting?
With a website custom audience built from the Meta pixel's purchase event, excluded from the prospecting ad set. She does not upload customer emails or phone numbers from Klaviyo to Meta, and she does not build lookalike audiences.
Does she build audiences, launch ads, or send emails on her own?
Not by default. She reads and reports across both freely. Building an audience or launching or editing an ad in Meta waits for your explicit yes in Slack, and anything new she builds there starts paused. Any Klaviyo send always waits for your yes.
Do I need both connected?
For the joined read, yes: Meta Ads for acquisition and the audiences, Klaviyo for retention and lifetime value. Each also works on its own; this page is about what they do together.
Can I keep her scoped to just part of the setup?
Yes. Connect only the accounts you want her in, and the rest stays untouched. By default, every change she makes waits for your yes, and every email, post or message she drafts always does.
