How to Audit Your Klaviyo Account in 30 Minutes (2026 Checklist)

Keeping your Klaviyo account healthy is crucial—inbox placement, open rates, and ultimately your revenue depend on it. If you haven’t done a checkup in months, this hands-on, 2026-focused guide will help you fix issues fast and suggest what to do if you’re in over your head.

In just 30 minutes, you’ll uncover hidden problems, fix the common gotchas, and identify instant wins that will supercharge your results.

You’ll need access to your Klaviyo account and, if possible, your ESP/platform admin (e.g., Shopify). Ready? Let’s go!

1. List Hygiene Check: Suppress Unengaged Profiles

Your deliverability—and wallet—depend on removing people who never engage. Here’s how to identify and suppress unengaged profiles in Klaviyo (2026 UI update).

Step-by-step:

Go to “Profiles”
In your Klaviyo account, use the left sidebar: Audience > Profiles.
Build your “Never Engaged” Segment
- Click Create Segment.
- Name it: Unengaged Subscribers - Audit 2026.
- Choose these conditions:
```
- Someone has received email at least 5 times over all time
AND
- Someone has opened email zero times over all time
```
  (You may adjust thresholds: e.g., “received at least 10 emails in the last 90 days and opened zero/never clicked.”)
Review and Suppress in Bulk
- Once the segment populates, click into it.
- Hit the Manage Segment > Select All (top-left) > Actions dropdown.
- Choose Suppress Profiles. This moves them to your suppression list—they won’t receive future sends and you won’t be charged for them.
- Optionally, download a list for compliance records.

Pro Tip:
Set a calendar reminder to repeat this every quarter.

2. Deliverability Health: Domain Authentication & Reputation

Poor deliverability means even your best email never gets read. Start with authentication and reputation stats.

(a) Domain Authentication (SPF/DKIM/DMARC)

Check if you’re properly authenticated:
- Go to Settings > Domains and Hosting in Klaviyo.
- Each sending domain should have a green “Authenticated” checkmark.
- If not, you’ll see “Action Required.”
  Follow Klaviyo’s guided setup (2026 makes this a one-click process if you use Shopify or most CNAME-supporting hosts).
Cross-verify in your DNS provider:
- You should see kl._domainkey, klaviyo-s1, and (optionally) DMARC records configured.
- If not sure, click “Recheck Records”.

Trouble Authenticating? Most issues relate to DNS propagation (wait up to 24 hours) or typos. If issues persist, consult your platform support or look up agencies at KlaviyoDirectory.com with “deliverability” expertise.

(b) Spam Complaint and Bounce Rates

Go to “Analytics > Email Health” dashboard
- Spam complaint rate: Should be under 0.08%.
- Bounce rate: Keep under 1% (ideally <0.5%).
- Unsubscribe rate: Normal to see 0.3-0.5% for campaign sends.
High numbers?
- Revisit your engaged segments (see Section 5).
- Review problematic campaigns—did subject lines or send times change?
- Consider A/B testing future sends.

3. Flow Audit: Are Core Flows Set Up & Performing?

Flows automate revenue and drive engagement. Make sure your “must-have” flows exist—and are working.

Core flows to review:

Welcome Series
Abandoned Cart
Browse Abandonment
Post-Purchase
Winback / Re-engagement

Steps:

Navigate:
Flows > Show All
Confirm Each Exists:
- If any core flows are missing, use Klaviyo’s ready-made templates to set up in <5 minutes.
Check Recent Performance:
- Click into each flow.
- Look at 30/60/90-day stats:
  - Email sends
  - Open/click rates (as of 2026, GDPR-compliant open rates may be lower—focus on clicks/conversions)
  - Revenue attributed
- If you see <10% open rates, or $0 revenue, something’s wrong (poor filters, content, or trigger).
Test each flow:
- Use “Preview & Test” on an email action inside the flow.
- Trigger a real test from your store if possible (e.g., abandon a cart yourself).

4. Revenue Attribution Sanity Check

Don’t blindly trust the “attributed” revenue Klaviyo shows—make sure it’s not inflated.

How to Check Realism:

Go to Analytics > Campaign Overview or Flow Performance
Compare Klaviyo-reported revenue to your store’s actual sales
- For last month, total up Klaviyo-attributed revenue.
- In Shopify (or your e-commerce backend), view real revenue for the period.
- Rule of thumb: Klaviyo should account for 20-40% of your total revenue if all flows/campaigns are running.
Red flags:
- If Klaviyo claims >70% of revenue is “attributed,” you likely have aggressive attribution windows (e.g., 10-day post-click/post-view).
- To adjust: Go to Settings > Attribution and set a realistic window (e.g., 5 days post-click, 1 day post-view).

5. Segment Health: Engaged vs. Unengaged

Are you sending campaigns to only those likely to open/click? A mistake here can destroy your deliverability.

Steps:

Make sure you have these segments:
- Engaged (Opened or clicked email in last 90 days)
- Unengaged (No opens or clicks in last 90/120/180 days)

How to Create:

Audience > Lists & Segments > Create Segment

Example Engaged segment filter:

- Someone has opened email at least once in the last 90 days OR
- Someone has clicked email at least once in the last 90 days

Check Recent Campaign Sends:
- On Campaigns > Sent, click into your last 2-3 campaigns.
- In “Recipients,” confirm you excluded unengaged segments.
Adjust as Needed:
- Update your campaign schedules to send only to engaged users by default.

Sending to too many unengaged users suppresses future inbox placement—even for your best subscribers!

6. SMS Evaluation: Are You Wasting Budget?

You’re paying for SMS credits—are you actually nurturing or converting with SMS?

Quick Check:

Go to Analytics > SMS Performance
- Do you have >$20 spent in the past 30 days, but no campaigns or flows enabled? That’s wasted spend!
Check Compliance
- Go to “Compliance” tab—ensure opt-in consent is up to date.
Review Flows:
- If SMS is toggled on for abandoned carts or new customers, check actual performance (open rates, clicks, conversions).
No SMS flows or campaigns, but billing active?
- Pause your SMS sending or reallocate budget.

7. Integration Check: Is Your E-Commerce Platform Syncing Correctly?

90% of Klaviyo issues originate from a faulty integration.

Steps:

Go to Integrations > Shopify (or WooCommerce, BigCommerce, etc.)
- Status should read Connected and “Active as of [recent date/time]”.
Trigger a Test Event:
- Place a test order or sign up for a newsletter from your live store.
- Go back to “Profiles” in Klaviyo. Search for your test profile—check if new activity is recorded.
Check Sync Health:
- If you see Sync Errors (especially product/contact sync), click for detailed logs.
- Reconnect integration if needed, or update app permissions.
