How to Audit an E-commerce Email Program

Most email "audits" are a screenshot of last month's revenue and a shrug. A real audit does one thing: it compares each number to a benchmark, decides whether it's good or bad on evidence, and turns every weak spot into a fix. Here's the method, generalized so it works on any platform.

First, fix your comparison set

A number means nothing on its own. A 29% open rate isn't good or bad until you compare it to peers. Before you grade anything, decide what you're grading against — all-industry medians (the honest default) or a specific vertical — and pull a rolling twelve months of data so seasonality doesn't distort your averages. State the comparison set in the report so your judgments are defensible, not opinion.

Grade six things, in order

• Campaigns — open, click, click-through, placed-order rate, revenue per recipient. The signal that matters most is the gap to median on click rate and revenue per recipient.
• Flows (automations) — the highest-leverage area (more below).
• SMS — click, placed-order, revenue per recipient, unsubscribe. Define "conversion" before quoting a benchmark; it means different things across sources.
• Sign-up forms — popup submit rate. Well under ~2% usually means a weak offer or too many fields.
• Audiences & segments — confirm the real mailable list size net of suppressed profiles, or every per-recipient metric is computed against the wrong denominator.
• Business performance — average order value, order count, return rate. Grade these against the account's own trailing baseline, not an industry median.

Lead with flows — that's where the money is

Automated flows typically generate 30–40% of total email revenue from only 2–5% of sends, with revenue per recipient many times higher than campaigns. Grade them against flow-specific medians (much higher than campaign medians), then judge each one individually with a simple verdict:

Keep it (at or above median) · Modify it (sound idea, weak execution) · Kill it (redundant or misfiring — turning a bad flow off is a legitimate, valuable recommendation).

"Your abandoned-cart flow is your best performer but browse-abandonment is dead weight" is worth ten times more than "flows are Fair."

Stop trusting open rate

Since Apple's Mail Privacy Protection began auto-opening messages, open rates are inflated across the board — well over half of opens are now machine-generated. Keep open rate in the report as context, but lead with clicks, conversions, and revenue. Those reflect real humans and correlate with money.

Turn the audit into a plan

An audit that doesn't become a plan is trivia. Here's the move most people miss: for every metric graded below "Good," set the KPI target equal to the peer median — not an aspirational number, the median. "You're in the bottom third on click rate; step one is reaching the middle of the pack. Here's the number, here's how." It makes targets credible and progress measurable, and it protects you from overpromising.

That's the whole method: benchmark everything, lead with flows and revenue, and map every weak grade to a median-based target and a tactic.
