Email brings in 12% of revenue. Welcome, abandoned cart, browse abandonment and post-purchase flows usually close most of this gap first.

Monthly gap to your target: $13,000

Why this number matters

Email is often the cheapest revenue a store has, because you already own the list. The calculator turns your store revenue, email revenue and list size into your current share, a target share, and the monthly gap between the two.

Use it to decide whether email deserves more attention before you spend more on ads.

The terms, in plain English

Every number this calculator uses, with an example.

Attributed revenue

Revenue your email platform credits to email or SMS because the buyer opened or clicked a message before buying.

FlowsAutomations

Emails sent automatically when a shopper does something, like signing up, leaving a cart or placing an order.

Welcome, abandoned cart and post-purchase are the common ones.

Campaigns

Emails you send to your list on a schedule, like a new product or a weekly newsletter.

List size

The number of subscribed profiles you can email.

Revenue per subscriber

Email revenue divided by list size, for the month. A quick way to compare your list against a bigger or smaller one.

AOVAverage order value

Your revenue divided by your number of orders.

$30,000 from 400 orders is a $75 AOV.

How it works

  1. 01Your current share

    Email revenue ÷ store revenue, using the attributed revenue your email platform reports for the month.

  2. 02Your target

    Many established Shopify brands aim for email and SMS to bring in 20 to 30 percent of revenue. Set the target that fits your store.

  3. 03The gap

    Store revenue × target − email revenue, shown per month and per year.

Questions about email revenue

01Where do I find email revenue?

In Klaviyo, the dashboard shows attributed revenue from flows and campaigns. Use the same month as your store revenue.

02Is attributed revenue accurate?

It is generous, since a customer who opened an email and bought later still counts. Use it to compare month to month rather than as an exact number.

03What usually closes the gap fastest?

Flows: welcome, abandoned cart, browse abandonment and post-purchase. They run every day without new work each week.
