Email marketing returns $42 for every $1 spent. You have read that hundreds of times.
Here is what that number actually is.
It is a 2019 figure, from the United Kingdom, denominated in pounds.
Not dollars. Not 2026. Not a like-for-like comparison with anything (Litmus, 2026).
The more current figure is $36 per $1, and it has its own problems.
Both are worth understanding, because email genuinely does work. 📧
It simply does not work the way the headline number implies.

| Claim | ما هو عليه في الواقع | حالة |
|---|---|---|
| $42 per $1 spent | 2019 UK figure, in pounds | Widely misquoted |
| $36 per $1 spent | More recent, self-reported | Better, still an average |
| How the ratio is computed | Email-attributed revenue divided by email spend | Attribution problem |
| Who publishes it | Email platform companies | Commercially interested |
| Variation between senders | Enormous, smoothed by averaging | Rarely mentioned |
| Best treated as | Order of magnitude, not a measurement | Per the sources themselves |
🔍 Where the $42 Came From
The number has a specific origin, and tracing it explains a lot.
It comes from a Direct Marketing Association study in the United Kingdom.
The measurement was in pounds sterling, and it dates to 2019.
🔍 How one number changed meaning
How it happened
Nobody set out to mislead. Each retelling dropped one qualifier.
The country went first, then the year, then the currency.
What remains is a bare number with no context attached.
Why the currency matters
A pound and a dollar are not the same amount of money.
Quoting a pound-denominated ratio in dollars changes what it claims.
The ratio itself is currency-neutral, but the framing is not.
Why the year matters more
Email in 2019 predates significant changes to privacy and tracking.
Measurement methods changed materially afterwards.
A 2019 attribution figure describes a different measurement environment.
⚠️ The Deeper Problem: Attribution
Even the current $36 figure has a structural issue worth understanding.
The ratio is calculated by dividing email-attributed revenue by email spend.
Email-attributed revenue is not the same as revenue email created.
| الوضع | Credited to email? | Caused by email? |
|---|---|---|
| Customer already intended to buy, clicks the email | نعم | لا |
| Customer had abandoned a basket, returns via email | نعم | Partly |
| Customer discovers a product in the email | نعم | نعم |
| Customer saw an advert, then used email as a shortcut | نعم | لا |
| Existing subscriber buying on a normal schedule | نعم | Probably not |
Only one row is unambiguously caused by the email.
Yet all five are counted in the attributed revenue.
Why email specifically inflates
Email reaches people who already chose to hear from you.
They are your existing customers, and they were likelier to buy anyway.
Email harvests intent efficiently. That is not the same as creating it.
What the honest measure would be
Incremental revenue, meaning sales that would not have happened otherwise.
Measuring it requires holding back a control group who receive nothing.
Very few businesses do this, and the published averages do not.
✅ Why Email Still Deserves Your Time
Having taken the headline apart, here is the honest case in its favour.
It does not rest on any ROI multiple.
| ميزة | Why it holds |
|---|---|
| You own the list | No platform can take it away |
| No algorithm between you and readers | Delivery is not rationed |
| Costs scale slowly | Ten times the list is not ten times the cost |
| Recipients opted in | They asked to hear from you |
| It works while you sleep | Automated sequences run themselves |
| Portable between providers | You can export and move |
The ownership point is the strongest one and the least quantified.
Social followers are rented. Email subscribers are yours.
The contrast that matters
A social platform can change its algorithm and halve your reach overnight.
It has happened repeatedly, to businesses that built everything there.
An email list keeps working regardless of anyone else’s decisions.
Why the cost structure helps small senders
Most platforms charge by list size, in bands.
Sending to 900 people usually costs the same as sending to 400.
So the return improves as the list grows, without extra spend.
🧮 Measuring Your Own Return Honestly
Forget the industry averages. This is the calculation that applies to you.
| خطوة | مثال |
|---|---|
| Annual platform cost | $240 |
| Your time, 2 hours monthly at $40 | $960 |
| Total real cost | $1,200 |
| Revenue attributed to email | $9,000 |
| Naive return | 7.5 to 1 |
| Assuming half would have bought anyway | 3.75 to 1 |
Note that the time cost is four times the platform cost.
Published ROI figures almost never include your hours.
Why halving is a reasonable default
Without a control group you cannot know the incremental share.
Halving is conservative and keeps you honest.
A return of nearly four to one is still excellent.
How to measure it properly
Hold back 10% of your list from one campaign.
Compare their purchase rate with everyone else’s.
The difference is the real effect, and it takes one campaign to learn.
📬 What Actually Drives Results
Since the averages describe nobody, here is what varies between senders.
📬 The factors that separate good programmes from poor ones
Permission is the biggest single factor
A list built from people who asked to join behaves completely differently.
A purchased or scraped list produces almost nothing, and damages your sending reputation.
How you gathered the addresses predicts the results better than anything else.
Relevance beats polish
A plain text message about something the reader wants outperforms a designed template about something they do not.
Sending everyone the same thing is the most common mistake.
Even splitting a list into two groups improves results noticeably (Mailneo, 2026).
Frequency is a real variable
Too rare and people forget who you are.
Too frequent and they stop opening, then unsubscribe.
Monthly is a safe starting rhythm for most small businesses.
📮 The Deliverability Problem
An email that lands in spam has a return of exactly zero.
This receives far less attention than open rates, and matters more.
| عامل | Effect on delivery |
|---|---|
| Authentication records set up | ضروري |
| Sending from your own domain | Strongly helps |
| Low complaint rate | Critical |
| Removing inactive subscribers | Helps considerably |
| Sudden large sends | Hurts, if unusual for you |
| Purchased lists | Damages reputation quickly |
| Misleading subject lines | Generates complaints |
Authentication is a one-off technical setup most small senders skip.
Without it, providers treat your mail with suspicion by default.
The counter-intuitive fix
Removing subscribers who never open improves your results.
A smaller engaged list delivers better than a large indifferent one.
Providers judge you partly on whether recipients engage (Eggknite, 2026).
Why complaints matter so much
One person marking you as spam counts heavily against you.
Make unsubscribing easy and obvious, because that is the better outcome.
An unsubscribe costs you one reader. A complaint costs you future delivery.
🌱 Growing a List From Nothing
The averages assume an established programme. Most people are not there.
| Method | سرعة | الجودة |
|---|---|---|
| Asking existing customers | Immediate | أعلى مستوى |
| A form on your website | Slow, steady | عالي |
| Something useful in exchange | Faster | Good, if relevant |
| In person, at the point of sale | ثابت | مرتفع جداً |
| Social media prompts | Variable | Mixed |
| Competitions and giveaways | سريع | Usually poor |
| Buying a list | فورية | Worthless |
The fastest methods generally produce the weakest subscribers.
People who joined for a prize want the prize, not your emails.
The most overlooked source
Your existing customers already know and trust you.
Most businesses have never simply asked them to subscribe.
One message to your current contacts often builds the first hundred.
What to offer in exchange
Something genuinely useful and specific to what you do.
A guide, a checklist, or a discount on a first order.
Generic offers attract generic subscribers.
⚖️ The Rules You Must Follow
Email marketing is regulated, and the rules are not optional.
| Requirement | لماذا |
|---|---|
| Permission before sending | Legally required in most places |
| Clear sender identity | Recipients must know who you are |
| A working unsubscribe link | Required, and must work |
| Acting on unsubscribes promptly | Usually within days |
| A physical postal address | Required in several jurisdictions |
| Honest subject lines | Deception is specifically prohibited |
Rules differ by country, and the strictest applicable one governs you.
If your list spans several countries, build to the strictest standard.
Why compliance also improves results
Every rule above describes what good senders do anyway.
Permission, honesty and easy unsubscribing all improve engagement.
The regulations largely codify what already works (Angarum Media, 2026).
Keep the evidence
Record when and how each subscriber joined.
Most platforms do this automatically if you use their forms.
That record is your defence if anyone ever queries it.
💵 What Email Platforms Actually Cost
Pricing in this category is banded by list size, which has an odd consequence.
💵 Cost per subscriber falls as the list grows
What this means in practice
If you pay for a band up to 1,000 subscribers, reaching 900 costs the same as 400.
Every subscriber added inside a band is effectively free to reach.
So growth improves your return without increasing your spend.
Watch the band boundaries
Crossing into the next tier can raise the bill sharply.
This is a good reason to remove subscribers who never open anything.
Pruning saves money and improves delivery at the same time.
Free tiers are genuinely usable
Most major platforms offer a free tier covering several hundred subscribers.
That is enough to run a real programme for a small business.

📈 What to Measure Instead of ROI
Four numbers tell you more than any return multiple.
| قياس | ما يكشف |
|---|---|
| List growth per month | Whether the asset is building |
| Unsubscribe rate per send | Whether you are sending well |
| Replies received | Genuine engagement, hard to fake |
| Revenue per subscriber per year | Comparable over time |
Revenue per subscriber is the most useful single figure.
It lets you compare this year with last year on your own terms.
Why replies deserve attention
Open rates became unreliable after privacy changes affected tracking.
Replies cannot be inflated by an image loading automatically.
A message that produces conversations is working (Tabular, 2026).
The unsubscribe signal
A small steady rate is healthy and normal.
A spike after one campaign tells you exactly what not to repeat.
Treat it as feedback rather than as loss.
🕰️ How Long Before It Works
Expectations here are usually wrong in both directions.
| المرحلة | ماذا تتوقع |
|---|---|
| First 3 months | List building, little revenue |
| Months 3 to 6 | First consistent responses |
| Months 6 to 12 | Patterns become readable |
| Year two onward | The compounding starts |
The averages you read describe programmes in the fourth row.
Comparing a three-month-old list against them guarantees disappointment.
Why year two is different
By then the list is larger and the audience knows you.
You also know what they respond to, which took a year to learn.
Most of the reported return comes from that accumulated knowledge.
The mistake that resets the clock
Stopping for six months undoes much of the progress.
People forget who you are and complaint rates rise on your return.
Consistency matters more than volume or polish.
✉️ What to Actually Send
The commonest reason small businesses stop is running out of ideas.
| يكتب | جهد | Usually works? |
|---|---|---|
| Answering a common question | قليل | نعم |
| Recent work or a finished job | قليل | نعم |
| A genuine offer with a deadline | قليل | نعم |
| Seasonal or timely advice | معتدل | نعم |
| Company news about you | قليل | نادرا |
| Long formal newsletters | عالي | Often not |
| Reused social media posts | Very low | لا |
The three easiest types are also the three that work.
Company news is the exception people default to first.
The question bank approach
Keep a note of every question a customer asks you.
Each one is a message, and you never run out.
You already know the answer, so writing takes minutes (Christopholivier Consulting, 2026).
Length is not the point
Three useful paragraphs beat a designed newsletter nobody finishes.
Short messages are also faster to write, so you keep sending them.
Sustainability matters more than any single message.
Write to one person
Imagine a single customer and write to them directly.
Messages addressed to an audience read as broadcasts and get ignored.
The word you want is “you”, not “our valued customers”.
🔁 Automated Sequences Worth Setting Up
Three automations do most of the work in small programmes.
| تسلسل | الزناد | قيمة |
|---|---|---|
| Welcome message | Someone subscribes | Highest engagement you will get |
| Abandoned basket | Checkout not completed | Strong, if you sell online |
| Post-purchase follow-up | After delivery | Reviews and repeat orders |
The welcome message is opened more than anything else you send.
Most businesses waste it on an empty confirmation.
What the welcome should do
Tell them what you will send and how often.
Give them one genuinely useful thing immediately.
Set the expectation you intend to keep, then keep it (Mailneo, 2026).
Why these three are enough
Elaborate automation suits large catalogues and large teams.
A small business gets most of the benefit from these three.
Add more only when these are working reliably.
🔀 Where Email Fits Beside Everything Else
Email works best as the destination, not as the whole strategy.
| قناة | Job it does | You control it? |
|---|---|---|
| بحث | Brings strangers who are looking | Partly |
| وسائل التواصل الاجتماعي | Builds familiarity over time | لا |
| الإعلانات المدفوعة | Buys attention immediately | While you pay |
| موقعك الإلكتروني | Converts interest into contact | نعم |
| بريد إلكتروني | Keeps the relationship alive | نعم |
Only the last two rows are genuinely yours.
The other channels rent you attention on their own terms.
The sensible sequence
Use the rented channels to bring people to something you own.
Convert that visit into an email address wherever you reasonably can.
Then the relationship continues without paying for reach again.
Why this matters more each year
Reach on rented platforms has become steadily more expensive.
Organic visibility fell as those platforms monetised attention.
An owned list is insulated from that trend entirely.
The one-line summary
Rent attention, then convert it into something you own.
That principle survives every change in platform economics.
🚫 ما لا تخبرك به هذه البيانات
Publishers sell email software. Litmus, Omnisend and Klaviyo all do.
Figures are self-reported. Companies estimate their own returns.
Averages hide huge variation. Your sector and list maturity dominate.
Attribution is not causation. Credited revenue overstates created revenue.
New lists behave nothing like mature ones. The averages assume established programmes.
The variation point deserves weight
These averages combine established retailers with new newsletters.
A business with 40 subscribers is not in the same distribution.
An average across a wildly varied population describes nobody.
To their credit
The sources themselves suggest treating these as order-of-magnitude confirmation.
That caveat is usually stripped out by the time you read the statistic.
The publishers are more careful than their popularisers (Litmus, 2026).
🏁 النسخة القصيرة
The $42 per $1 claim is a 2019 UK figure measured in pounds.
Quoting it as current US dollars compounds two separate errors.
The current figure of $36 is better but still self-reported and attributed.
Attributed revenue counts sales that would have happened anyway.
Email still deserves your effort, for a reason no multiple captures.
You own the list, and no algorithm sits between you and your readers.
Measure your own return, include your hours, and hold back 10% to see the truth. 📧

❓ الأسئلة المتداولة
Is the $42 per $1 email ROI figure accurate?
It is a 2019 United Kingdom figure denominated in pounds. Quoting it as current dollars is doubly wrong.
What is the better figure?
Around $36 per $1, which is more recent. It remains self-reported and based on attribution.
What is wrong with attribution?
It credits email with sales that would have happened anyway. Credited revenue overstates created revenue.
So is email marketing worth doing?
Yes, but for a different reason. You own the list, and no algorithm can reduce your reach.
How do I measure my own return?
Include your hours, not just the subscription. Time usually costs several times the software.
How do I find the real effect?
Hold back 10% of your list from a campaign and compare purchase rates. That difference is incremental.
Why do platforms publish these numbers?
They sell email software. That does not make the figures false, but it explains the emphasis.
Do the averages apply to a small list?
Not really. They combine established retailers with new senders, and a 40-person list is not in that distribution.
Is email better than social media?
For reliability, yes. Social reach depends on an algorithm you do not control and cannot appeal.
Does list size change the economics?
Yes, favourably. Platforms charge in bands, so a growing list often costs nothing extra to reach.
What should I do first?
Start collecting addresses, with permission, before you worry about which platform to use.

حول هذا التحليل
This article traces a widely repeated statistic to its origin and identifies two compounding errors in how it is quoted: currency and date. The more current figure is presented with its methodological limitation, which is that attributed revenue is not incremental revenue. All the sources sell email software or services, and that is stated. The case made for email marketing deliberately does not rest on any return multiple. Checked on August 8, 2026.
