Klaviyo Flow Audit: How to Score Every Email Flow in Your Account

If you're using Klaviyo and not generating at least 30% of your e-commerce revenue from email, you almost certainly have a flow infrastructure problem. Not a traffic problem. Not a product problem. A Klaviyo flow problem.

A proper Klaviyo flow audit doesn't just check whether flows exist — it evaluates their quality, timing, segmentation logic, and revenue contribution against what top-performing brands in your sector are achieving.

This guide covers all 10 flows you should have in your Klaviyo account, what to look for in each, how to score them, and what the gaps are likely costing you every month.

The 10 Flows Every Klaviyo Account Should Have

Before scoring individual flows, you need to establish which flows exist in your account. In Klaviyo, go to Flows → All Flows. You're looking for these 10 core flows:

#	Flow	Trigger	Revenue Impact	Difficulty
1	Welcome Series	List join / signup form	Very High	Low
2	Abandoned Cart	Added to cart, no purchase	Very High	Low
3	Abandoned Checkout	Started checkout, no purchase	Very High	Low
4	Browse Abandonment	Viewed product, no cart add	High	Low
5	Post-Purchase Series	Order placed	High	Medium
6	Win-Back / Sunset	No engagement in 90+ days	Medium	Low
7	VIP & Loyalty	3rd purchase or £LTV threshold	High	Medium
8	Replenishment	Estimated consumption date	Medium	Medium
9	List Health / Deliverability	Ongoing — suppression & hygiene	Very High	Low
10	Segmentation & Personalisation	Ongoing — RFM & dynamic content	High	High

How to Score Each Klaviyo Flow

For each flow that exists, score it on a 0–100 scale across these five criteria:

• Sequence completeness — Does it have the right number of emails? (Welcome: 5–7, Cart: 3, Checkout: 2, Post-Purchase: 5)
• Timing logic — Are delays appropriate? (Cart Email 1: 1hr. Cart Email 2: 24hr. Cart Email 3: 72hr.)
• Conditional splits — Does it handle purchasers mid-flow? Does it split VIPs from standard subscribers?
• Content quality — Subject line formulas, dynamic product blocks, personalisation tokens
• Exclusion logic — Are subscribers excluded from flows they've already converted from?

Scoring Guide: What Each Grade Means

Grade	Score	What It Means	Priority
A	90–100	Best-in-class. Hitting or exceeding industry benchmarks across all criteria.	Monitor only
B	78–89	Good. Minor improvements available but not urgent.	Optimise next quarter
C	62–77	Average. Significant revenue being left on the table vs benchmark.	Improve this month
D	45–61	Below average. Multiple critical issues with measurable revenue impact.	Fix this week
F / Missing	0–44	Critical or absent. This flow is costing you real revenue every day it's broken.	Immediate priority

What Each Missing Flow Is Costing You

The revenue impact of missing flows varies by your account size, but these are reliable benchmarks based on industry data:

• No abandoned checkout flow: Typically 8–12% of checkout abandonments are recoverable. At 80 abandonments/month and £40 AOV, that's ~£2,400–£3,840/month unrealised.
• No browse abandonment flow: Converts 2–5% of product viewers. Lower individual impact but high volume makes it significant — typically £400–£800/month at mid-size brands.
• Only 1 abandoned cart email: Email 2 (social proof, 24hr) and Email 3 (incentive, 72hr) generate approximately 65% of total cart recovery revenue. If you only have Email 1, you're leaving two-thirds of the money behind.
• No win-back flow: Beyond direct revenue, this means unengaged subscribers are sitting in your list damaging deliverability — reducing open rates across all your sends by 30–50%.

The Welcome Series: Most Underestimated Flow

The welcome series is the highest-leverage flow in any Klaviyo account. New subscribers are at peak engagement — open rates of 50–70% are normal in Email 1. Despite this, most brands send 2 emails and stop.

A benchmark welcome series looks like this:

1. Email 1 (immediate): Warm welcome, brand story, what to expect. No hard sell.
2. Email 2 (Day 2): Your bestsellers or most-loved products. Social proof.
3. Email 3 (Day 4): Educational content — how to use your products, what makes you different.
4. Email 4 (Day 7): First-purchase incentive with a clear expiry date.
5. Email 5 (Day 10): Objection handling — returns policy, reviews, trust signals.
6. Email 6 (Day 13): Final urgency email before incentive expires.
7. Email 7 (Day 16): Community / long-term relationship email for non-converters.

A critical addition most brands miss: a conditional split after Email 1 checking whether the subscriber has placed an order. Subscribers who purchase within 24 hours should exit to your post-purchase flow immediately — not continue receiving acquisition emails.

Abandoned Cart: The 3-Email Rule

Single-email abandoned cart flows are the most common and most costly mistake in Klaviyo. The data is clear: a 3-email sequence generates 2–3x the revenue of a single email, with the second and third emails doing the majority of the work.

The optimal sequence:

• Email 1 (1 hour): Simple reminder. Dynamic product block. No discount — too early.
• Email 2 (24 hours): Social proof — reviews, ratings, how many people bought this. Reinforce the decision.
• Email 3 (72 hours): Your best offer — 10–15% discount or free shipping. Time-limited (48 hours).

Deliverability: The Silent Multiplier

Poor deliverability is a multiplier on every other problem. If 15% of your emails land in spam, every open rate, CTR, and revenue figure is 15% lower than it should be — regardless of how good your flows are.

In your Klaviyo flow audit, check these deliverability indicators:

• Are you sending campaigns to your full list, or an engaged segment (opened/clicked in last 90 days)?
• Is DMARC set to at least p=quarantine at your domain registrar?
• Do you have a dedicated sending domain configured in Klaviyo settings?
• Is your bounce rate below 2% and complaint rate below 0.08%?

Running a Klaviyo Flow Audit Manually vs Using a Tool

A manual Klaviyo flow audit takes 6–8 hours if you know what you're doing, and significantly longer if you don't. You need to log into Klaviyo, pull metrics for each flow, compare them against benchmarks, calculate revenue impact, and build a prioritised action plan.

Alternatively, KlavAudit Pro completes the same audit in 60 seconds using AI — scoring all 10 flows, calculating your monthly revenue gap, and producing a 90-day roadmap. It optionally connects to your Klaviyo account via a read-only API key for live data, or works from your brand inputs alone.
