What should an email marketing report to a client contain?
Four things: what you sent, what it achieved, what you learned, and what you will do next. Everything else is decoration. A client report is not a data dump — it is an argument that the money was well spent, supported by numbers.
The most common failure is exporting every metric the platform offers and calling it reporting. A client who receives forty figures and no interpretation concludes one of two things: that nothing notable happened, or that you are hiding the part that did.
The metrics clients care about versus the ones you care about
These are not the same list, and confusing them is why reports get skimmed.
| You need | They need | Why |
|---|---|---|
| Open rate | Reach — how many people saw it | Open rate is a diagnostic for you, not an outcome for them |
| Click rate | Traffic and what it did | A click only matters if it led somewhere |
| Bounce rate | List health, in plain words | They care that the list is sound, not the percentage |
| Unsubscribe rate | Whether the audience is tiring | Frame it as audience sentiment, not a statistic |
| Deliverability detail | Only when there is a problem | Silence here means it is working |
| Conversions and revenue | This above all | It is the only number tied to their decision to keep paying you |
Lead with the outcome, then support it. "The March campaign brought 412 visitors and 23 orders" is the headline; the open rate is a footnote that explains how you got there.
A report structure that works
Keep the same shape every time. Clients learn where to look, and comparison across months becomes possible.
- Summary in plain language. Three sentences, no jargon, readable by someone who was not involved. If the client reads only this, they should still know how the month went.
- What was sent. Campaign names, dates, audience size. This is the record of work done, and it matters more than people expect when an invoice is questioned.
- Results against the previous period. Absolute numbers are meaningless alone. Every figure should sit beside last month's.
- What performed and what did not. Name the winning subject line and the losing one. This is the section that proves you were paying attention.
- List health. Growth, losses, and the net. A shrinking list is a problem worth raising before the client notices it themselves.
- What happens next. Two or three specific actions with dates. This turns a report into a plan and is the single best defence against "what are we actually paying for?"
Six sections, two pages. A longer report is not a better one.

How often should you send a client report?
Monthly for most retainers. It is long enough to show a trend and short enough that problems surface before they become expensive.
Two exceptions are worth making. Send a short note after any campaign that mattered — a launch, a sale, anything the client was personally invested in — because waiting three weeks to discuss it looks like indifference. And report immediately when something goes wrong, rather than burying it in the monthly. A deliverability problem you raise yourself is competence; the same problem discovered by the client is negligence.
Weekly reporting sounds diligent and usually is not. Email results are too noisy week to week, and you end up explaining variance instead of progress.
Making the report look like your work
If you are an agency, a report carrying another company's logo quietly undermines you. The client sees the tool, wonders what you add, and the next conversation is about your fee.
White-labelling fixes the obvious part — your logo, your colours, your name on the PDF. But presentation alone is not the whole job. The interpretation is what the client is actually buying: the paragraph that says what the numbers mean and what you will do about them. A branded report with no analysis is still a data dump, just a better-looking one.
Practical rules: put your logo and the client's name on the cover, keep the same file naming convention every month, and send the report as an attachment or link that does not require the client to log into anything. Every login you impose reduces the number of people who read it.
Running reports across multiple clients
Agencies hit the same wall at around five clients: separate logins, separate exports, and a reporting week that eats the margin on the work.
The fix is structural rather than clever. Keep each client's data genuinely separate so that no export can cross-contaminate. Give team members their own access rather than sharing one password, which matters for audit as much as security. And standardise the report so that producing it is assembly, not authorship.
Mailpro's multi-user access lets each person on your team work under their own account, and our guide to managing multiple client accounts covers the account structure in more depth. The campaign statistics are where the underlying numbers come from.
Mistakes that make clients distrust a report
Trust in reporting is lost through small things, and it does not come back easily:
- Changing the metrics between months. Reporting open rate when it looks good and clicks when it does not is the fastest way to be caught.
- Percentages without denominators. "Up 40%" from what to what? A client who has to ask has already stopped believing the number.
- Silence about a bad month. Every channel has them. A report that never contains bad news is not read as reassuring; it is read as unreliable.
- Numbers that contradict the client's own analytics. They will compare. Explain the difference before they find it — platform clicks and website sessions never match exactly, and saying so in advance costs nothing.
- Vanity framing. "Best open rate ever" on a campaign sent to a tenth of the usual audience is technically true and professionally embarrassing.
Turning the report into the next conversation
The best client reports end with a question rather than a full stop. Proposing the next test — a subject-line experiment, a segment worth trying, a send-time change — moves the meeting from reviewing the past to deciding the future, which is where retainers get renewed.
It also means the following month's report has a built-in narrative: here is what we said we would try, here is what happened. Over a year, that sequence is far more persuasive than twelve disconnected sets of statistics.
Frequently asked questions
What should be in an email marketing report for a client?
What was sent, results compared with the previous period, list health, what worked and what did not, and the specific actions you will take next. Lead with outcomes such as traffic and conversions; keep diagnostic metrics like open rate as supporting detail.
How often should agencies report on email campaigns?
Monthly for most retainers, plus a short note after any campaign the client cared about and an immediate one whenever something goes wrong. Weekly reporting usually generates noise rather than insight.
Should the report include open rates?
Include them, but do not lead with them. Open rates have become an unreliable headline because of privacy protections that pre-load images, so they are best treated as a directional signal rather than a result.
Can I put my own logo on the reports?
Yes, with white-label reporting the PDF carries your branding rather than the platform's. This matters for agencies because a report branded by your supplier invites the client to wonder what they need you for.
Why do my numbers differ from the client's website analytics?
Because they measure different moments. Your platform counts clicks at the click; their analytics counts sessions that arrived and could be measured. Consent choices and blocked scripts sit between the two. Explain the gap once, in the first report, and it never becomes an argument.
How long should a client report be?
Two pages, or one page and an appendix for anyone who wants the detail. The constraint is useful: it forces you to decide what actually mattered this month.
What to do when the results are bad
Every account has a month where the numbers go the wrong way, and how you report it determines whether the client treats you as a partner or a supplier.
Say it first, in the summary, in one sentence. Burying a decline on page two reads as hoping nobody notices. Then give the cause if you know it, and say plainly that you do not if you are still investigating — a confident wrong explanation is worse than an honest gap. Finally, state what changes next month. Clients tolerate bad results far better than they tolerate the impression that nobody is steering.
One nuance worth keeping in mind: a single weak campaign is noise, and treating it as a crisis trains the client to panic at normal variance. Reserve the serious framing for a trend across three or more sends, and say explicitly which of the two you think you are looking at.
