# Email marketing ROI calculator: revenue from your list

> Email revenue = emails delivered × open rate × click-to-open rate × conversion rate × average order value. ROI compares that revenue with the cost of your email platform, content and design. Because open rates are inflated by privacy features such as Apple Mail Privacy Protection, clicks and orders are the more reliable measures of how a list performs.

## How it is calculated

- **Orders**: subscribers × campaigns × delivery rate × open rate × click-to-open rate × conversion rate
- **Revenue**: orders × average order value
- **ROI**: (revenue − email costs) ÷ email costs

## Campaigns vs automated flows

Campaigns are one-off sends to the list. Automated flows — welcome series, abandoned cart, post-purchase and win-back emails — are triggered by behaviour and typically earn much more revenue per email, because they arrive at the moment of intent.

If most of your email revenue comes from campaigns, setting up the core flows is usually the fastest way to improve ROI.

## Why open rates are unreliable

Apple Mail Privacy Protection and some corporate filters open emails automatically, inflating open rates. Judge performance mainly on clicks, orders and revenue per email, and use click-to-open rate to compare content.

## Ways to improve email marketing ROI

- Segment by interest, purchase history and engagement.
- Remove inactive subscribers to protect deliverability.
- Authenticate your domain with SPF, DKIM and DMARC.
- Test subject lines, offers and send times.
- Make every email lead to one clear action.

## FAQ

### How do you calculate email marketing ROI?

Subtract email marketing costs from the revenue emails generated, then divide by the costs. $5,000 revenue from $500 costs is a 900% ROI, or $10 per $1 spent.

### What is a good email marketing ROI?

Industry surveys often cite returns of tens of dollars per dollar spent, but results vary widely by industry and list quality. Compare against your own past performance.

### What is a good click-to-open rate?

Many brands see roughly 5–15%. It measures how compelling the content is to people who opened.

### How much is an email subscriber worth?

Divide yearly email revenue by the number of subscribers. The calculator shows this as revenue per subscriber per year.
