The Email Outreach KPIs You Should Review Monthly

Review delivery, open, click, reply, positive reply, meeting, close, cost per meeting, CAC, ROI, and complaint rate on a monthly cadence — weekly for engagement and deliverability, monthly for economics. The KPIs that predict revenue are positive reply rate, meeting rate, and cost per meeting.

The point of the review is to catch a leaking stage early, not to celebrate sends. Pair every rate with its absolute count.

Positive reply rate shows whether messaging earns interest. Meeting rate shows whether interest becomes a conversation. Cost per meeting and CAC show whether the campaign pays. Close rate shows whether conversations become revenue.

Open and click rates belong in the review as diagnostics — they explain leaks but are not outcomes. A dashboard headlined on opens hides losing campaigns.

Weekly: delivery, open, click, reply, positive reply, and complaint trends. Monthly: cost per meeting, CAC, ROI, and close rate versus your working assumptions. Per campaign: actuals against conservative, working, and upside forecasts. Quarterly: replace benchmark ranges with your own verified rates.

Assign one owner to the review so it actually happens. A KPI with no owner is not reported.

A funnel chart (sent → delivered → opened → replied → meeting → client) with counts and rates. A trend line of reply and positive reply rate per wave. A cohort table by list segment or offer. A cost chart of cost per meeting and CAC versus target.

Show counts next to rates so a small sample is not mistaken for strong performance — a 50% meeting rate from two replies is not the same as 50% from 200.

End each review with one change and one validation test: tighten targeting, adjust the offer, or fix deliverability. Measure that single variable on the next wave so the review compounds instead of producing another deck.
