Most email audits never happen because they sound like a week of work. Spreadsheets. Screenshots. A 40-page deck nobody reads.
You don't need any of that. You need 30 minutes and a notebook.
This is the audit I run when I open a new Klaviyo account for the first time. It's not exhaustive. It won't catch every deliverability nuance or every broken segment. But it will tell you, within half an hour, where the actual money is leaking out of your email program.
Before you start
Open three tabs:
- Klaviyo dashboard
- Your live website (incognito, signed out)
- A blank doc or notebook
Set a timer for 30 minutes. The point is to stay out of rabbit holes. If something looks broken, write it down and keep moving. You can fix it later.
Minute 0-5: the signup experience
Go to your website in the incognito tab. Try to sign up for the email list like a new visitor would.
Watch what happens. Did the popup show up? How fast? Did the form actually submit? Did you get a welcome email within 60 seconds?
You'd be amazed how many brands have a broken popup or a welcome series that hasn't sent for two weeks because of a flow trigger issue nobody noticed. The signup experience is the first thing every new subscriber sees. If it's broken, nothing downstream matters.
Write down anything that felt slow, ugly, or off. Move on.
Minute 5-10: the flow inventory
In Klaviyo, go to Flows. Look at every active flow. Write down:
- Which ones are live
- When each was last edited
- What the trigger is
You're looking for two things. First, flows that exist but haven't been touched in over a year. Email evolves fast. A welcome series written in 2024 is probably saying things your brand has moved past.
Second, gaps. Most DTC brands have a welcome series and an abandoned cart, and that's it. Where's the browse abandonment? Where's the post-purchase replenishment? Where's the win-back?
Don't try to build anything yet. Just inventory what exists and what doesn't.
Minute 10-15: the campaign rhythm
Pull up your campaign send history for the last 60 days. Look at it as a calendar, not a list.
Where are the dense weeks? Where are the silent weeks? Did you send 4 emails in 7 days during a promo, then go dark for 12 days afterward?
This is the pattern that quietly kills engagement. Burst then silence, burst then silence. Subscribers can't tell when to expect you, so they tune out.
A good email rhythm has gaps that feel natural, not random. Two to three campaigns per week, spaced thoughtfully, with planned silence around major holidays so you're not screaming into the same voice everyone else is using. If you're struggling with cadence, planning 90 days ahead makes these patterns visible before they become problems.
If your calendar looks like a heart monitor, that's your number one fix.
Minute 15-20: the unsubscribe pattern
Go into your campaigns and sort by unsubscribe rate, highest first.
Look at the top five. What do they have in common? Same segment? Same time of day? Same kind of offer? Same subject line pattern?
Unsubscribes are noisy signal, but the top of the list is usually telling you something. If your highest-unsubscribe campaigns are all to the same segment, that segment is fatigued or wrongly defined. If they're all the same type of offer (say, every aggressive discount email), your audience is telling you the discount strategy isn't matching their expectations of your brand. Learn more about what unsubscribe rates actually mean.
Write down what the top five have in common. Don't act on it yet. Pattern matching is the whole point here.
Minute 20-25: the segment audit
Go to your segments list. This is where most accounts have hidden garbage.
You're looking for:
- Segments that haven't been used in 6+ months
- Segments with overlapping definitions (e.g., "engaged 30 days" and "engaged 60 days" that don't have a clear use case)
- Segments where the member count is suspiciously low or high
- Segments named after a campaign you ran in 2024
Klaviyo segments accumulate like browser tabs. Everyone keeps making new ones, nobody deletes the old ones, and after two years you've got 80 segments and you only actively use 6. This is exactly the maintenance nightmare most teams eventually hit.
Don't delete anything during the audit. Just star or note the ones that look like clutter. A clean segment list makes the rest of your job easier for the next year.
Minute 25-30: the metric reality check
Open your account dashboard. Look at:
- Overall open rate (last 30 days vs previous 30)
- Click-to-open rate
- Placed order rate from email
- Revenue per recipient on your last 5 campaigns
If your open rate has dropped more than 5 points in the last 60 days, something's wrong. Could be deliverability. Could be subject line fatigue. Could be that you're emailing too often and the inbox providers are quietly downranking you.
If your click-to-open rate is trending down but open rate is steady, your subject lines are working but your content isn't. People are opening out of habit and not finding anything worth clicking.
If your revenue per recipient is dropping while send volume goes up, you're harvesting your list. That's the most expensive mistake in email, because it doesn't show up in revenue until it suddenly does.
What to do with what you found
Don't try to fix everything. You'll burn out and nothing will get done.
Pick the top three findings and turn them into actual work for the next two weeks. Maybe it's "rebuild the welcome series" and "delete 40 dead segments" and "redo the campaign cadence for July." Three things, two weeks. That's enough.
The rest goes in a backlog. You'll get to it next month. Or you won't, and that's fine, because the top three are doing most of the work anyway.
Where Cadento helps
The audit itself is something you can do in any tool. But the part that's hard to see inside Klaviyo is the rhythm. Klaviyo shows you campaigns as a list, sorted by date. It doesn't show you what your subscriber actually experienced over the last 60 days.
That's what Cadento is built for. You see your full email program (campaigns and flows) on a visual calendar, so the dense weeks and silent weeks become obvious. The pattern you'd have to squint at in Klaviyo is right there on the screen.
A lot of audit findings come down to "I had no idea my calendar looked like that." Seeing the timeline is the audit.
The takeaway
Email audits don't have to be huge projects. Thirty minutes, three tabs, one notebook.
The point isn't to find everything wrong. It's to find the three things wrong that are costing you the most, and to fix those before the next big sending window.
Set a timer. Run the audit. You'll know more about your email program after 30 minutes than most brands ever bother to find out.
