Your email list is the highest-ROI channel you own — and probably the most neglected. Plug in your numbers and see what it's actually worth, what it could be worth, and how much revenue is quietly leaking out the bottom.
No account, no email gate. Drag the sliders — everything updates instantly.
Engaged, opted-in contacts — not the ghosts who haven't opened in a year.
Same list, three programs. The difference between healthy and best-in-class isn't more subscribers — it's how the list is run. That spread is the money we go after.
Estimates for planning only, based on published email marketing benchmarks and your inputs. Actual results depend on offer, list quality, segmentation, and how consistently you send. We can't confirm your list's real numbers without looking at your account — book a call and we will.
Short version: email is the best-performing channel most brands own, and it's not close.
Across the industry, email marketing returns an average of $36–$42 for every $1 spent — a 3,600–4,200% return. Paid social and paid search can't touch that, because you already own the audience and aren't renting attention from an ad auction every single day.
ROI does vary by industry. Here's where the benchmarks land (Litmus State of Email data):
| Industry | Return per $1 spent |
|---|---|
| Travel, tourism & hospitality | $53 |
| Retail & ecommerce | $45 |
| Marketing, PR & advertising | $42 |
| Software & technology | $36 |
| Media & publishing | $32 |
If your email program is returning less than ~$20 per $1, something is broken — usually thin automation, no segmentation, or a "batch and blast" newsletter doing all the heavy lifting. That's exactly the gap the calculator above is showing you.
The core formula is refreshingly simple:
So if email drives $50,000 in revenue and costs you $2,000 in software and management, that's ($50,000 − $2,000) ÷ $2,000 × 100 = 2,400% ROI, or $25 back for every $1 in.
The trick is attributing revenue honestly. Do:
The rule of thumb: a healthy list earns about $1 per subscriber per month. Dialed-in lists earn far more.
Notice the range: a best-in-class program is worth 3× a healthy one from the exact same list. That's not a bigger list — it's a better-run one. Engagement almost always matters more than raw size; a smaller, loved list out-earns a big, ignored one every time.
Which is the whole point of the "left on the table" number above: for most brands, the fastest revenue win isn't more traffic or more subscribers. It's getting more out of the list you already have.

The industry average is $36–$42 in revenue for every $1 spent (3,600–4,200% ROI). Retail and ecommerce brands often see ~$45, and travel/hospitality tops $50. If you're below ~$20 per $1, there's real upside on the table — usually in automations and segmentation.
Use: (Revenue from email − Cost of email) ÷ Cost of email × 100. Count both campaign and automated-flow revenue, use a consistent attribution window, and include your true costs (platform + design + management). The calculator above does this math for you.
A healthy list earns roughly $1 per subscriber per month. Strong programs hit $1.50–$2, and best-in-class ecommerce lists reach $3+. Your number = total monthly email revenue ÷ active subscribers.
Because email ROI is so high, the constraint is usually capacity, not budget. Most small-to-mid brands run a solid program — platform plus management — for a few hundred to a few thousand dollars a month, and it pays for itself many times over. The right question isn't "how little can I spend," it's "how much revenue is my under-built list leaving behind?"
The usual suspects: no automated flows (or only a bare welcome email), sending the same blast to everyone with zero segmentation, poor deliverability from a stale list, and inconsistent sending. Any one of these caps your revenue per subscriber. Fixing them is typically where the fastest wins live.
If email is under ~15–20% of your revenue and you know it should be more, an agency usually pays for itself fast — the lift in revenue per subscriber outruns the fee.
