Every email platform opens on a dashboard full of numbers: delivered, opened, clicked, bounced, unsubscribed, complained, revenue, click-to-open, and a few more. After a few campaigns you have a spreadsheet of percentages and no clear idea whether the newsletter is doing anything for the business.
This guide sorts email marketing metrics into the ones that tell you something useful, the ones that warn you of trouble, and the ones you can mostly ignore. It ends with a one-page monthly report a small business owner can read in a couple of minutes, whether they send the emails themselves or pay someone to.
Start from what the email was for
No number means much until you know what the email was supposed to achieve. Before looking at a report, write down the purpose in one line.
- “Get bookings for the new weekend batch.”
- “Tell customers we have moved.”
- “Sell the remaining festive gift boxes.”
- “Keep us in mind between purchases with a useful tip.”
An announcement of a move succeeds if people turn up at the new address, even if nobody clicks. A sales email succeeds if it sells. Judging both by the same click rate makes no sense. Measure each email against its own goal first, then look at the general health numbers.
Clicks, used carefully
A click shows that someone followed a link. It is the most widely available sign of interest, and far more reliable than opens.
- Total clicks and unique clickers: how many people clicked at least once, and how many clicks there were in total.
- Click rate: unique clickers divided by emails delivered. Useful for comparing your own campaigns over time.
- Which links got clicked: often the most useful part of the report. It shows which topics, products or offers people care about.
Two cautions. Security systems at some workplaces follow links automatically, which can add clicks no person made; they usually show up as every link clicked at the moment of delivery. And “click-to-open rate” depends on opens, which are unreliable, so treat it loosely. Our explanation of why opens are no longer a fair count covers that.
Replies
Most platforms do not count replies, because replies go to your inbox, not theirs. Count them anyway, even roughly. A reply is a real person, in their own words, telling you what they think, asking a question, or placing an order. For a service business, a handful of replies can matter more than any percentage on the dashboard.
Make sure the reply-to address goes to an inbox someone reads, and keep a simple tally per campaign.
What happened on the website
This is where email earns its keep. Did people who clicked go on to enquire, book, buy or call?
- Tag every link with campaign parameters, so visits from the email are labelled in your analytics rather than appearing as direct or unknown traffic. Our campaign link builder makes this quick, and many email platforms can add the tags automatically.
- Track the actions that matter on your site: form submissions, bookings, purchases, calls. Our guide to setting up conversions in GA4 covers the basics.
- Look at those actions by source in your analytics, filtering to your email campaigns.
Platforms that connect to your store often show their own revenue figures. These can differ from your analytics and from your order records, because each counts differently. When they disagree, trust the one closest to your actual orders and treat the others as estimates.
Unsubscribes and complaints
These are warning signals, and reliable ones, because a person had to act.
- Unsubscribes: some are normal after every send, as people’s needs change. Watch for a jump after a particular email, which tells you something about its content, timing or frequency.
- Spam complaints: far more serious. Even a small number harms your sending reputation. If complaints appear, look at where those subscribers came from and whether the email matched what they signed up for.
If your platform asks unsubscribers why they left, read the answers. “Too many emails” and “not relevant to me” are both fixable.
Bounces and delivery
- Hard bounces: addresses that do not exist. A sudden rise usually means old or poor contacts were imported.
- Soft bounces: temporary problems such as full mailboxes. A rise at one particular provider can point to a deliverability issue there.
- Delivered: the receiving server accepted the email. It does not mean the email reached the inbox; it may be in spam.
The platform cannot see where accepted mail lands. Seed tests to your own addresses at different providers, and replies from real subscribers, are the only reliable way to check.
List growth, and where it comes from
Track how many people joined and left each month, and the net change. More useful still: tag each subscriber by signup source, such as footer form, checkout, blog, counter or a particular lead magnet, and compare the sources over time by how many of their subscribers click and buy. A source bringing fewer but more engaged subscribers is worth more than one bringing many who never click.
Email marketing metrics you can mostly ignore
- Open rate, as a measure of readers. It is inflated by privacy features and missing for people who block images. Watch it only for sudden changes.
- Industry benchmark averages. They mix very different lists and are distorted by automatic opens. Compare against your own past figures.
- List size on its own. A big list of silent addresses is a liability.
- Single-campaign swings. One email doing better or worse tells you little. Look at trends across several sends.
- Heat maps and device charts, unless you are actively redesigning the template.
How to measure email campaigns in a one-page monthly report
Whether you write it yourself or receive it from someone else, a monthly email report can fit on one page.
| Line | What to show |
|---|---|
| What was sent | Each campaign and automation that ran, with its purpose in one line |
| Results against purpose | Bookings, orders, enquiries or replies from each, where trackable |
| Clicks | Unique clickers per campaign, and the top links |
| Replies | Rough count, with a note of anything notable |
| Health | Unsubscribes, complaints and bounces, with any unusual jump explained |
| List | Joined, left, net change, and the best-performing signup source |
| Next month | What will be sent and what will change, based on the above |
If a report you receive leads with open rates and skips everything below “clicks”, ask for the rest. It is a reasonable request of anyone running your email.
Email is one source among several in that kind of report. Our small business digital marketing guide shows how the same thinking applies to search, ads and social, so no channel gets credit for activity alone. The wider plan for newsletters, from first subscriber to first report, is set out in our guide to email marketing for small businesses.
Frequently asked questions
What is a good click rate for a small business newsletter?
There is no single good figure, because it depends on your list, your trade and what each email asks people to do. Track your own click rate over several months and aim to keep it steady or improving. A rising trend, with clicks going to the links you care about, is a better sign than beating someone else’s average.
Why does my email platform show sales that my analytics does not?
They count differently. The platform may credit a sale to email if the buyer clicked any email in a set period beforehand, while your analytics may credit the visit that came just before the purchase. Neither is wrong, they simply answer different questions. Check both against your actual orders.
How long should I wait before judging a campaign?
Most clicks happen soon after sending, but bookings and purchases can follow days later, especially for considered buys. Look at clicks after a few days and at enquiries or sales after a week or two, then compare across several campaigns before drawing firm conclusions.
Should I track unsubscribes per email or per month?
Both are useful. Per email shows whether a particular message, topic or send time put people off. Per month, against the size of your list, shows the general trend. A steady small number is normal; a sudden jump after one email is the thing to investigate.
If you would like your email results reported in plain terms, with tagged links and website conversions tracked properly, our email marketing services include a simple monthly summary.
