What is email marketing ROI?

An AI email generator is a tool that writes a draft email from a few details you give it, like the email type, tone, length, and what the email is about. It uses a large language model to turn those details into ready-to-edit copy. You review the draft, adjust it to fit your brand’s voice, and send it.

How to calculate email marketing ROI

ROI = (Revenue − Cost) ÷ Cost × 100

Example: a campaign costs $150 and brings in $3,000 in sales. ($3,000 − $150) ÷ $150 × 100 = 1,900% ROI.

How to use the email marketing ROI calculator

Fill in four fields to see what a campaign earned, or check how much it needs to bring in to break even.

1
Preferred currency

Pick the currency you report in: U.S. dollars, euros, or British pounds. This only changes the symbol, so enter all amounts in the same currency.
2
Email send volume

Enter how many contacts received the campaign. For a more precise result, subtract the emails that bounced.
3
Cost of email marketing campaign

Enter what this one campaign cost: your monthly platform fee divided by the campaigns you send each month.
4
Total sales

Enter the revenue the campaign brought in. If you use Omnisend, you’ll find it in your campaign reports.

How to read your results

Cost per subscriber

Campaign cost ÷ email send volume. It shows what you paid to reach each contact.

Total revenue

The sales your campaign brought in, as you entered them. Every other result builds on this number.

Total profit

Total revenue − campaign cost. It shows what the campaign earned after paying for itself, or how much it lost if the number is negative.

Revenue per email

Total revenue ÷ email send volume. Use it to compare campaigns of different sizes.

ROI

Total profit ÷ campaign cost × 100. An ROI of 1,900% means $19 in profit for every $1 spent. A negative ROI means the campaign cost more than it made.

Sales to break even

The sales you need to cover your campaign cost. If a campaign costs $150, you need $150 in sales before it turns a profit.

What is a good email marketing ROI?

Compare your result with these averages. The benchmark that matters most, though, is your own ROI over time.

Campaigns are one-off sends to your list, like a sale announcement. Automations are triggered by what a shopper does, like signing up or leaving a cart, so they reach people at the right moment. In Omnisend’s 2025 data, automations clearly outperformed campaigns.

FAQ

How do I calculate email marketing ROI?

Subtract the campaign cost from the revenue it brought in, divide by the cost, and multiply by 100. For example, $3,000 in sales from a $150 campaign is ($3,000 − $150) ÷ $150 × 100 = 1,900%. Or enter your numbers in the calculator above.

What is a good email marketing ROI?

On average, email brings in $36 in revenue for every $1 spent (Litmus). Omnisend merchants on paid plans averaged $79 per $1 across email, SMS, and push in 2025. To compare, divide your total sales by your campaign cost. The most useful benchmark, though, is your own ROI over time.

What costs should I include in email ROI?

For a quick check, use your email platform fee split across the campaigns you send each month. That’s what this calculator is built for. For a fuller picture, also add design or agency fees, copywriting, staff time, and any extra tools used for the campaign.

How much is a 1,000-subscriber email list worth?

It depends on your revenue per email. At $0.20 revenue per email and four campaigns a month, 1,000 subscribers bring in about $800 a month, or $9,600 a year. Enter your numbers in the calculator to find your revenue per email, then multiply it by your list size and sends.

How can I increase my email marketing ROI?

Start by automating welcome, abandoned cart, and post-purchase emails, which earn far more per email than campaigns. Then segment your list so offers reach the right shoppers, grow it with sign-up forms, add SMS to your automations, and A/B test subject lines and content to see what sells.

What is the difference between email ROI and ROAS?

ROI compares profit with total cost: (revenue − cost) ÷ cost. ROAS compares revenue with spend: revenue ÷ spend. ROI shows whether a campaign made money after costs; ROAS shows how much revenue each $1 brought in.

Is this calculator free?

Yes. The email ROI calculator is free, and you don’t need to sign up. It runs in your browser, so the numbers you enter aren’t sent or stored. Use it as often as you like to check past campaigns or see what your next one needs to break even.
