Klaviyo Audit Checklist: 50 Points to Review
A proper Klaviyo audit uncovers the specific issues draining your email revenue. Most ecommerce brands leave thousands of pounds on the table because their flows aren't triggered correctly, their deliverability setup is flawed, or their campaigns hit spam folders instead of inboxes.
This checklist walks you through 50 critical audit points across account settings, flows, campaigns, list health, segmentation, and performance metrics. Each section focuses on measurable outcomes that directly impact revenue per recipient (RPR) and overall retention.
We've structured this guide around the exact framework we use when auditing Klaviyo accounts for D2C brands. You'll get specific benchmarks to target, technical configurations to verify, and prioritisation criteria to focus on high-impact fixes first.
Why You Need to Audit Your Klaviyo Account
Your Klaviyo account holds your most valuable marketing asset: direct access to people who've already shown interest in your brand. Yet the majority of accounts we review suffer from preventable issues that suppress performance.
Technical misconfigurations harm sender reputation. Poor flow logic sends the wrong messages at the wrong times. Weak segmentation treats VIP customers the same as one-time buyers.
The business impact shows up in your metrics. Flows generate nearly 41 percent of total email revenue from just 5.3 percent of sends, which means flow optimisation delivers disproportionate returns.
Revenue per recipient (RPR) serves as a better indicator of marketing effectiveness than open rates or click-through rates alone. An audit identifies exactly where your RPR falls short of its potential.
Deliverability issues compound over time. A rising bounce rate or increasing spam complaints damage your sender reputation, which reduces inbox placement for all future emails.a
The Cost of Not Auditing
Neglected Klaviyo accounts develop systematic problems. Flows continue triggering based on outdated logic. Campaigns blast entire lists instead of targeted segments. Technical setup drifts further from best practices.
Revenue leaks through multiple failure points simultaneously. Your abandoned cart flow might miss 30 percent of potential recoveries because the trigger conditions exclude certain checkout types. Your welcome series might fail to convert because the timing gaps lose momentum.
Compliance violations create legal exposure. The penalties for CAN-SPAM violations can reach $53,088 per email, whilst GDPR fines can reach €20 million or 4 percent of global revenue.
What a Systematic Audit Delivers
A structured Klaviyo audit reveals your highest-leverage opportunities. You discover which flows need rebuilding versus simple tweaks. You identify which segments drive revenue versus which dilute performance.
Audit findings create your action plan. Technical fixes come first because they affect everything downstream. Flow optimisation follows because flows generate the highest revenue concentration. Campaign and segmentation improvements compound these gains.
The outcome: a prioritised roadmap that focuses effort where it generates measurable returns. You stop guessing and start optimising based on data.
When and How Often to Conduct a Klaviyo Audit
Audit frequency depends on your sending volume and business changes. High-volume senders benefit from quarterly audits. Most ecommerce brands should audit every six months minimum.
Trigger an immediate audit when you notice performance deterioration. A sudden drop in open rates signals deliverability problems. Declining flow revenue suggests broken triggers or poor segmentation.
Major business changes require audits. New product launches, website migrations, platform integrations, or significant list growth all introduce variables that affect email performance.
Audit Triggers and Timing
Schedule audits around your business calendar. Post-peak-season audits (after Black Friday/Cyber Monday, after Christmas) catch issues before they affect the next major period.
Consider these specific audit triggers:
- Bounce rate increases above 2 percent threshold
- Open rates decline 15 percent or more from baseline
- Flow revenue drops month-over-month without seasonal explanation
- New Klaviyo features release that affect your use cases
- Marketing team changes or agency transitions
First-time audits often surface years of accumulated issues. Expect to find multiple problems requiring systematic fixes rather than quick patches.
Resource Allocation for Audits
Plan for 8-12 hours of focused work for a thorough audit of an established account. Complex accounts with extensive flow libraries and segmentation require more time.
Break the audit into focused sessions. Technical setup review takes 2-3 hours. Flow audit requires 3-4 hours for comprehensive accounts. Campaign and segmentation analysis needs 2-3 hours. Performance metrics review takes 1-2 hours.
Document everything as you audit. Create a spreadsheet tracking each audit point, current state, benchmark comparison, and required action. This documentation becomes your implementation roadmap.
Step 1: Audit Your Account Settings and Deliverability
Technical infrastructure determines whether your emails reach inboxes at all. Poor sender authentication, misconfigured domains, or compliance gaps sabotage everything built on top.
Start with sender authentication protocols. Verify your SPF, DKIM, and DMARC records are properly configured and aligned with your sending domain.
Check your dedicated sending domain setup. Klaviyo accounts should use a dedicated subdomain for email sending, separate from your primary website domain. This isolates your sender reputation from other email activities.
Email Authentication and Domain Configuration
Log into your domain registrar and verify your DNS records. Your SPF record should include Klaviyo's sending servers. Your DKIM record should show a valid public key that matches Klaviyo's configuration.
DMARC policy protects against spoofing whilst providing feedback on authentication failures. Set your DMARC policy to at least "p=quarantine" for meaningful protection.
Test your authentication using tools like MXToolbox or Google's Email Checker. Both should confirm all three protocols (SPF, DKIM, DMARC) pass validation.
Sender Reputation and Deliverability Metrics
Review your bounce rate in Klaviyo's account-level metrics. An email bounce rate of less than two percent is considered good. Higher bounce rates indicate list quality problems or technical issues.
Check spam complaint rates. Rates above 0.1 percent trigger deliverability problems with major inbox providers. Complaints above 0.3 percent often result in sending restrictions.
Monitor your unsubscribe rate trends. Sudden increases signal content misalignment or frequency problems. Gradual increases might indicate list fatigue or poor segmentation.
Compliance and Privacy Settings
Verify your subscription forms include proper consent language. GDPR requires explicit opt-in for EU subscribers. CAN-SPAM requires clear identification and functioning unsubscribe mechanisms.
Check your SMS compliance setup separately. SMS regulations require explicit written consent. Verify your SMS forms capture this consent and store it properly in subscriber profiles.
Review your data retention policies. Configure automatic profile deletion for unsubscribed contacts after your required retention period. This reduces storage costs and demonstrates privacy compliance.
Audit your preference centre configuration. Give subscribers granular control over email types and frequency. This reduces blanket unsubscribes and improves engagement from remaining subscribers.
Step 2: Audit Your Email and SMS Flows
Flows drive the majority of your automated revenue. Yet most accounts run flows built months or years ago, never updated as the business evolved.
Start your flow audit by listing every active flow. Note the trigger type, number of messages, and current status for each. This inventory reveals scope and identifies obviously broken flows.
Check each flow's trigger configuration first. Triggers determine who enters the flow and when. Misconfigured triggers either miss qualified people or include the wrong audience.
Welcome Flow Audit
Your welcome flow converts new subscribers into customers. Welcome emails have an average open rate of 51 percent, making them your highest-engagement opportunity.
Verify your welcome flow triggers correctly. The most common trigger is "Subscribed to List" with appropriate list filters. Check that the trigger excludes people who are already customers if you want a prospect-only welcome series.
Review message timing. The first email should send immediately or within 5 minutes. Subsequent emails typically space 1-3 days apart, though optimal timing varies by industry and product consideration cycle.
Audit your welcome flow content progression. The sequence should move from brand introduction to product education to purchase incentive. Each message should provide value whilst building toward conversion.
For more detailed guidance on building high-performing welcome sequences, see our complete guide to Klaviyo flows for ecommerce.
Abandoned Cart Flow Optimisation
Abandoned cart flows recover otherwise lost revenue. Abandoned cart flows average a revenue per recipient of £3.07, making them one of your highest-value automations.
Check your abandoned cart trigger definition. The trigger should fire when someone adds items to cart but doesn't complete checkout. Verify the trigger includes appropriate filters to exclude people who later completed purchases.
Review your timing strategy. Most brands send 3-4 emails: one after 1-4 hours, another after 24 hours, a third after 48-72 hours, and optionally a final attempt after 5-7 days.
Audit your abandoned cart content. The first email should remind and reassure. The second might introduce social proof or urgency. The third could offer a small incentive if needed to close the sale.
Verify your abandoned cart flow excludes people who abandon repeatedly without purchasing. Serial abandoners might be using your flow as a discount mechanism. Add flow filters to limit frequency for the same person.
Post-Purchase Flow Review
Post-purchase flows drive repeat purchases and build customer lifetime value. These flows convert one-time buyers into repeat customers.
Check your post-purchase trigger. It should fire when someone places an order, with filters to segment by product category, order value, or customer type if you need different sequences.
Review your post-purchase email sequence. Typical sequences include order confirmation, shipping notification, delivery confirmation, product education, review request, and replenishment or cross-sell offers.
Verify timing aligns with your product delivery and usage cycle. Don't request reviews before customers receive products. Don't send replenishment offers before reasonable consumption time passes.
Browse Abandonment and Other Behavioural Flows
Browse abandonment flows target people who view products but don't add to cart. These flows capture earlier-stage interest than abandoned cart sequences.
Check your browse abandonment trigger configuration. It should track product views and exclude people who subsequently added to cart or made purchases.
Review timing and frequency caps. Browse abandonment should trigger after a reasonable delay (2-4 hours typically) and shouldn't spam people who browse frequently without buying.
Audit your flow filters and exclusions across all behavioural flows. People should exit flows when they complete the desired action. Flows should respect frequency caps to avoid overwhelming subscribers.
Understanding re-entry criteria and flow update changes helps you configure flows that respond appropriately when subscriber behaviour changes.
Step 3: Audit Your Campaign Performance
Campaigns complement your flows with timely, relevant broadcasts. Whilst flows run automatically, campaigns let you respond to business events, seasonal opportunities, and specific promotions.
Review your campaign sending frequency. Too many campaigns fatigue your list and increase unsubscribes. Too few campaigns miss revenue opportunities and reduce brand presence.
Check campaign performance trends over the past 90 days. Look for patterns in open rates, click rates, and revenue per recipient. Declining metrics signal content or frequency problems.
Campaign Metrics Analysis
Pull campaign-level data from Klaviyo's reporting. Export open rate, click rate, bounce rate, unsubscribe rate, and revenue per recipient for your recent campaigns.
Compare your performance to relevant benchmarks. The average open rate for e-commerce email marketing in 2026 is approximately 37.93 percent. Your specific benchmarks vary by industry and list characteristics.
Calculate your revenue per recipient across campaigns. RPR reveals which campaign types and content themes generate actual revenue versus just engagement metrics.
Identify your top-performing campaigns. What made them successful? Was it the subject line, the offer, the timing, the segment, or the content approach?
Campaign Segmentation Review
Check which segments receive your campaigns. Campaigns sent to broad, poorly targeted segments underperform compared to tightly focused sends.
Review your campaign segment definitions. Do they reflect meaningful customer differences? Do they target people most likely to respond to the specific offer or content?
Audit for over-mailing. Check how often individual subscribers receive campaigns. People who receive daily emails might engage less than those who receive 2-3 per week.
Our email segmentation strategies guide provides detailed frameworks for building segments that improve campaign performance.
Campaign Content and Design Audit
Review your campaign templates for mobile optimisation. With mobile now accounting for sixty-eight percent of email opens, subject line length has become more critical. Mobile displays truncate subject lines after 30-40 characters.
Check your email design renders correctly across email clients. Test on Gmail, Outlook, Apple Mail, and mobile clients. Klaviyo's preview function helps identify rendering issues.
Audit your call-to-action clarity and placement. Each campaign should have a clear primary action. The CTA should appear above the fold and repeat in longer emails.
Review image-to-text ratio. Emails with too many images often trigger spam filters or display poorly when images are blocked. Aim for balanced content that works even without images loading.
Step 4: Audit Your Lists and Segmentation Strategy
List health and segmentation quality determine the effectiveness of everything else. A clean, well-segmented list delivers better engagement, higher revenue per recipient, and stronger deliverability.
Start by reviewing your list growth trends. Check how many new subscribers you add monthly and through which sources. Declining growth rates signal problems with your acquisition strategy.
Audit your list composition. What percentage are engaged subscribers versus inactive profiles? How many are customers versus prospects? What's the distribution across key segments?
List Hygiene and Maintenance
Check for duplicate profiles. Klaviyo's profile merging attempts to consolidate duplicates automatically, but manual review often finds additional consolidation opportunities.
Review your suppression lists. These should include hard bounces, unsubscribes, and spam complainers. Verify these profiles are properly excluded from all sending.
Audit your engaged versus unengaged split. Define "engaged" based on your sending frequency (typically opened or clicked in past 90-180 days). Plan sunset or win-back campaigns for unengaged subscribers.
Check for obvious data quality issues. Invalid email formats, role addresses (info@, sales@), and disposable email domains all reduce list quality and harm deliverability.
Segmentation Strategy Review
List all your active segments in Klaviyo. For each segment, note the criteria, approximate size, and primary use case. This inventory reveals overlapping segments and gaps in your segmentation approach.
Review your behavioural segments. Do you segment by engagement level, purchase history, browsing behaviour, and product interests? These segments typically outperform demographic segmentation alone.
Check your customer lifecycle segments. Segment by prospect versus customer, one-time buyer versus repeat customer, and VIP versus average customer. These lifecycle stages require different messaging approaches.
Audit your segment sizes. Very small segments might not justify dedicated flows or campaigns. Very large segments might benefit from further subdivision to improve relevance.
Profile Data and Custom Properties
Review what profile data you collect and how you use it. Check that your Shopify integration (or other ecommerce platform) syncs the expected customer data to Klaviyo profiles.
Audit your custom properties. Are you tracking the properties you need for effective segmentation? Are there unused properties cluttering your setup?
Verify your calculated metrics are working correctly. Check that properties like predicted next order date, predicted customer lifetime value, and purchase frequency calculate as expected.
For Shopify users specifically, our Klaviyo Shopify integration walkthrough covers proper setup to ensure accurate data flow.
Step 5: Review Your Subscriber Acquisition and List Growth
List growth quality matters more than speed. A smaller list of engaged subscribers outperforms a larger list of disinterested contacts.
Review all your subscription forms. Check embedded forms on your website, popup forms, and any third-party integrations that add subscribers to Klaviyo.
Audit the value proposition on each form. Does it clearly communicate what subscribers will receive and how often? Vague promises like "stay updated" underperform specific value statements.
Form Performance Analysis
Check conversion rates for each signup form. Klaviyo's form analytics show views, submissions, and conversion rates. Low-converting forms need better placement, clearer value propositions, or revised incentives.
Review your form targeting and display rules. Popup forms should appear at optimal times, not immediately on page load. Exit-intent triggers often outperform time-based or scroll-based triggers.
Audit your signup incentives. First-purchase discounts drive signups but may attract discount-seekers who never buy at full price. Content-based incentives (guides, early access) often attract higher-quality subscribers.
Acquisition Source Quality
Segment subscribers by acquisition source. Compare engagement rates and purchase rates across sources. This reveals which channels deliver quality subscribers versus just volume.
Check for list-buying or poor-quality sources. Sudden list growth followed by poor engagement indicates problematic acquisition methods. These subscribers damage deliverability more than they help revenue.
Review your double opt-in settings. Double opt-in reduces list size but dramatically improves list quality and deliverability. The trade-off usually favours quality over quantity.
Growth Trend Analysis
Calculate your net list growth rate. This accounts for both new subscribers and list churn from unsubscribes and bounces. Healthy lists show consistent net positive growth.
Compare growth rates across acquisition channels. Identify which channels drive sustainable growth versus one-time spikes that don't repeat.
Project future list size based on current trends. Declining growth rates eventually lead to list stagnation or shrinkage, which limits revenue potential.
Step 6: Analyse Key Performance Metrics and Benchmarks
Performance metrics reveal the outcomes of all your Klaviyo activities. This final audit step connects technical setup, flow configuration, campaign execution, and list quality to actual business results.
Start with your highest-level metrics. Pull total email revenue, total email sends, and calculate overall revenue per recipient for your entire Klaviyo account.
Compare current performance to historical trends. Look at month-over-month and year-over-year changes. Identify positive trends to amplify and negative trends to reverse.
Revenue Attribution and Performance
Review attributed revenue by channel. Compare flow revenue, campaign revenue, and overall email revenue contribution to total store revenue.
Check revenue per recipient by message type. Flows typically generate higher RPR than campaigns. Within flows, certain types (abandoned cart, post-purchase) usually outperform others.
Audit your conversion attribution windows. Klaviyo's default attribution window might not match your customer buying cycle. Adjust attribution windows to reflect realistic consideration periods for your products.
Understanding the full retention lifecycle helps contextualise these metrics. Our customer retention playbook provides frameworks for measuring and improving retention outcomes.
Engagement Metrics Benchmarking
Pull your account-wide engagement metrics from Klaviyo's analytics. Calculate average open rate, click rate, and click-to-open rate across all sends.
Compare to industry benchmarks whilst recognising that your specific benchmarks depend on your industry, product type, and list characteristics. Focus more on your own trends than absolute benchmark comparisons.
Segment engagement analysis by subscriber lifecycle stage. Newer subscribers typically show higher engagement than older ones. Customers usually engage differently than prospects.
Deliverability and List Health Metrics
Review deliverability metrics over time. Track bounce rate trends, spam complaint trends, and unsubscribe rate patterns. Gradual deterioration signals growing problems before they become critical.
Calculate your engagement rate (opened or clicked in past 90 days). Low engagement rates below 20-30 percent indicate list quality problems that will eventually harm deliverability.
Check your sender score if you have access to deliverability monitoring tools. Scores below 80 suggest reputation problems that reduce inbox placement.
Strategic Performance Assessment
Beyond individual metrics, assess your overall Klaviyo strategy effectiveness. Does your email marketing drive meaningful business outcomes?
Calculate email's contribution to customer lifetime value. Track how email influences repeat purchase rates, average order value, and purchase frequency for email subscribers versus non-subscribers.
Review your testing and optimisation cadence. How many A/B tests did you run in the past quarter? What did you learn and implement? Systematic testing drives continuous improvement.
This strategic view often benefits from our outcome-focused approach. We explore this philosophy in depth in our article on optimising results rather than tasks in Klaviyo.
Prioritising Your Audit Findings and Next Steps
Your audit likely uncovered multiple issues requiring attention. Not everything needs fixing immediately. Some problems block others, whilst some deliver quick wins that build momentum.
Sort findings into three priority tiers. Priority one includes technical issues affecting deliverability, broken flows losing revenue, and compliance violations creating legal risk. Fix these first.
Priority two covers flow optimisations, campaign improvements, and segmentation refinements. These drive incremental revenue gains and engagement improvements. Tackle these systematically after resolving priority one items.
Priority three includes nice-to-have enhancements, experimental tests, and long-term strategic initiatives. These create future value but don't address current problems.
Creating Your Implementation Roadmap
Document each audit finding with its current state, target state, required actions, and estimated effort. This becomes your implementation roadmap.
Estimate the impact and effort for each item. Quick wins (high impact, low effort) should happen first after critical fixes. High-effort, high-impact projects need proper planning and resource allocation.
Set realistic timelines. Most comprehensive Klaviyo optimisations take 4-8 weeks to implement fully. Break large projects into phases to show progress and maintain momentum.
