Email platforms report a dozen percentages, and the one everyone quotes — open rate — has become the least trustworthy: privacy features in major mail clients now auto-load emails, inflating “opens” that never happened. Opens are a weather report; clicks and revenue are the harvest.
This guide sorts email metrics into three tiers — vanity, diagnostic, and money — gives rough healthy ranges for each, and pairs every weak number with its specific fix. It’s the email sibling of the five ad numbers that matter and feeds the same monthly owner dashboard.
It’s also how Fredeveloper reports email: revenue first, diagnostics behind it, vanity in the appendix where it belongs.

Three TiersVanity, Diagnostic, Money
Infographic 01 · The metric pyramid
From sends to money — where each metric sits
Tier 1 · Vanity (glance, don’t manage by)
Open rate — still useful for subject-line A/Bs and trend direction within your own list, but inflated and uneven since mail-privacy changes; never compare it across lists or report it as success. List size — a stockpile, not a result; 20,000 silent contacts lose to 2,000 buyers.
Tier 2 · Diagnostic (the operator’s dashboard)
- Click rate: the first honest engagement number — commonly 1–3% of delivered for broadcasts, far higher for automated flows. Sagging clicks = content or offer problem.
- Deliverability trio — bounces (<1%), unsubscribes (<0.5%/send), spam complaints (<0.1%): the list’s vital signs. Breaches here outrank every other fix.
- Click-to-open: of those who looked, how many acted — isolates whether the content delivered on the subject line’s promise.
Tier 3 · Money (the owner’s two numbers)
- Revenue per send: what each campaign earned — e-commerce platforms track it natively; service businesses count enquiries × close rate × customer value. The number that settles ‘was that email worth it.’
- Revenue per subscriber per month: the asset’s yield — total email revenue ÷ list size. It makes list-building math concrete and exposes whether growth is adding buyers or ballast.
Fix MapWhen a Number Sags: the Matching Fix
| Sagging number | Usual cause | The fix |
|---|---|---|
| Opens trending down (within your own list) | Stale subject lines, fatigued list, sender-reputation drift | Refresh formats; suppress 6-month-silent contacts; check the deliverability trio |
| Clicks low despite decent opens | Content doesn’t match the subject; no single clear call to action | One job per email, one obvious link; cut the everything-newsletter |
| Clicks fine, conversions poor | The landing page, not the email | Audit the page the click lands on — the email did its job |
| Unsubscribes spiking on one send | That send missed the list’s expectations | Re-read what subscribers were promised at signup; segment next time |
| Spam complaints rising | Cold contacts, unclear consent, all-promo content | Stop, clean, re-permission — then rebuild the rhythm value-first |
| Revenue per subscriber falling as list grows | Growth adding low-intent contacts | Fix the capture incentive — quality of source over volume |
If your email report were two lines, they’d be: revenue per send (campaigns) and revenue per flow (automations), each vs last quarter. Everything else exists to explain movement in those two.
How We WorkHow Fredeveloper Reports Email
Page one of our email report: revenue by campaign and by flow, revenue per subscriber, and a plain-language paragraph on what we changed and what’s next. Diagnostics sit behind it; vanity sits in the appendix. The same tracking layer feeds your overall marketing dashboard, so email’s contribution stands next to ads and SEO in identical units — dollars. Ask for a sample report before signing with anyone.
FAQFrequently Asked Questions
What’s a good open rate?
For small-business lists, 30–45% is common — but treat it as directional only: privacy features auto-trigger opens, inflating the number unevenly. Use it to compare your own subject lines over time, never as a success metric on its own.
What’s a good click rate?
Broadcast campaigns commonly land at 1–3% of delivered; automated flows run several times higher because timing does the targeting. Below ~1% persistently usually means diffuse content — too many messages per email, no single clear action.
How do I track email revenue as a service business?
Count the enquiries each send produces (unique links, reply tracking, ‘mention this email’), then apply close rate × average customer value. Imperfect, but it converts email from a faith activity into a line you can manage.
My platform shows revenue — can I trust its attribution?
Platforms tend to claim generously (e.g. any purchase within days of an open). Use it consistently for comparing your own campaigns; cross-check the total against your overall numbers before quoting it as gospel.
Are automated flows measured the same way?
Same metrics, different benchmarks — flows earn far higher clicks and revenue per email because they’re triggered by behaviour. Report them separately from campaigns; blending the two hides whether either is working.
Which single metric should I watch if I only watch one?
Revenue per subscriber per month. It rolls list quality, content, frequency, and conversion into one yield figure — and it’s the number that makes every email decision (grow, send more, clean, segment) into arithmetic.
