# How to compare email performance across stores fairly

> A store with 200,000 subscribers will out-earn one with 8,000 every month. Compare rates, not totals, to see which stores really need help.

Agencies and multi-brand owners face the same question every month: across all these stores, each with its own Klaviyo account, which ones are doing well? Ranking them by email revenue answers a different question. The biggest list wins, every time.

## Compare rates, not totals

**1 rule** compare rates, not totals, when stores differ in size

- Revenue per recipient, for campaigns and flows separately.
- Click rate, the cleaner engagement number now that Apple Mail inflates opens.
- Unsubscribe and spam complaint rates, to spot a store that's wearing its list out.
- Email's share of the store's total revenue, to see how much the business leans on email.

These put a candle shop with 5,000 subscribers and an apparel brand with 300,000 on the same footing.

## Group stores before you rank them

Even rates don't compare cleanly across very different businesses. A store selling $400 furniture will usually have a lower placed order rate than one selling $30 snacks, and that doesn't mean its emails are worse. Compare each store with similar stores: same category, similar prices, similar list size. Better still, compare each store with its own last quarter.

## Look for gaps, not just rankings

The most useful cross-store view is often a checklist rather than a league table. Which stores are missing an abandoned checkout flow? Which haven't sent a campaign in three weeks? Which have a spam complaint rate creeping toward 0.1%? Those gaps are quick wins, and they matter more than whether a store ranks fourth or fifth.

> A league table tells you who's ahead. A list of gaps tells you what to fix on Monday.

## Ask your own numbers in Wizel

Wizel connects each client's Klaviyo account in one workspace, so the chat can answer across all of them at once:

- “Compare campaign performance across all my stores.”
- “Rank my stores by revenue attribution.”
- “Which store is missing key automation flows?”

## FAQ

### What's the fairest metric for comparing email across stores?

Revenue per recipient, split into campaigns and flows. It accounts for list size. Pair it with click rate and unsubscribe rate, so a store that earns by over-sending doesn't look like a winner.

### Should I compare clients with industry benchmarks?

Only as a loose sense check. Benchmarks blend very different businesses. A store's own trend, and how it compares with similar stores you manage, tells you more.

### How often should an agency review performance across stores?

Monthly for reporting, with a weekly look at list health, like bounces and spam complaints, because those problems build quickly.
