Definition
Email reporting is the practice of collecting, analysing, and presenting email marketing performance data to stakeholders in a structured, actionable format. Effective email reporting serves three distinct audiences with different needs: the email team requires granular, real-time data to optimise campaigns day-to-day; marketing leadership needs trend analysis and comparative performance across campaigns and channels; and executives need summary-level ROI, revenue contribution, and strategic recommendations. A 2023 survey from Litmus found that 43% of email marketers spend at least 5 hours per week on reporting, with the most efficient teams using automated report generation tools to reduce this by 50-70%.
Report structure varies by audience and frequency. Weekly reports for the email team typically include campaign-level metrics (deliverability, engagement, conversion) with segment breakdowns, A/B test results, and quick recommendations. Monthly reports for marketing leadership add trend comparisons (month-over-month and year-over-year), channel performance comparisons, budget tracking, and strategic insights. Quarterly executive summaries focus on top-line contribution — email as a percentage of total revenue, ROI calculation, list health score, and major initiatives or risks. Best-in-class reporting uses data visualisation (sparklines for trends, bar charts for comparative data, heat maps for engagement patterns) rather than raw tables to communicate findings faster.
Best Practices
-
Automate report generation and distribution: Configure automated report generation within your ESP or analytics platform to reduce manual reporting time. Most platforms support scheduled PDF or dashboard delivery via email. Automation ensures reports are delivered consistently on schedule and frees the email team for analysis and action rather than data collection.
-
Create a reporting hierarchy from executive summary to deep-dive: Structure reports so the first page contains the most critical information — revenue impact, top-line metrics vs target, key wins and warnings — with subsequent pages providing progressively more detail. An executive can stop after page one. An analyst can continue through appendices with segment-level data and technical metrics.
-
Use period-over-period comparisons consistently: Report metrics with month-over-month (MoM), quarter-over-quarter (QoQ), and year-over-year (YoY) trend columns so stakeholders can see directionality. A single period's metric is meaningless without context. Include trailing 12-month trend lines on charts to provide the longest available context for performance evaluation.
-
Benchmark against internal targets not industry averages: Set annual email performance targets based on your own historical data and business objectives, then report performance against those targets. Industry benchmarks can appear in a "context" callout box but should not be the primary comparison point. Internal targets are more actionable and reflect your specific business context.
-
Include a recommendations section in every report: Data without action is just noise. Every report, from weekly team updates to quarterly executive summaries, should conclude with 3-5 specific, prioritised recommendations based on the data presented. Assign owners and target dates for each recommendation to ensure accountability.
-
Match reporting frequency to stakeholder needs: Weekly: email team, containing campaign-level metrics and optimisation opportunities. Monthly: marketing leadership, containing trends, benchmarks, and strategic insights. Quarterly: executives, containing ROI, revenue attribution, and high-level recommendations. Adjust frequency and depth based on actual stakeholder engagement with reports — if a weekly report goes unread for a month, reduce its frequency.

A/B Testing
A/B testing in email marketing is the practice of sending two variations of an email to a small sample of your list to determine which version performs better before sending the winner to the remaining subscribers.
Bounce Rate
Email bounce rate is the percentage of emails that were rejected by the receiving server before reaching the recipient. It is a key indicator of list health and data quality.
Click-Through Rate
Click-through rate (CTR) is the percentage of email recipients who clicked one or more links in your email campaign. It measures how compelling your content and call-to-action are.
Click-to-Convert Rate
Click-to-convert rate measures the percentage of email clicks that result in a desired conversion action such as a purchase, signup, or download. It shows how effective your post-click experience is at turning interest into results.
Click-to-Open Rate
Click-to-open rate (CTOR) is the percentage of email opens that resulted in at least one click. It measures how compelling your email content is for people who already opened it.
Conversion Rate
Email conversion rate is the percentage of delivered emails that resulted in a desired action such as a purchase, sign-up, or download. It measures how effectively your email campaign drives business results.
Frequently Asked Questions
Include four to six metrics at most: email-attributed revenue (or conversions), ROI (return on investment), list health score (composite of engagement, growth, and churn), year-over-year performance trend, top-3 initiatives or wins, and any risks requiring leadership attention. Executives need narrative and directionality, not data dumps. Keep the executive report to one page if possible.
Email ROI is calculated as (revenue attributable to email — total cost of email marketing) / total cost of email marketing. Total costs include technology (ESP fees, analytics tools), people (salaries, contractors), production (copywriting, design), and advertising (list acquisition, sponsored placements). Attribution requires a consistent model — last-touch, multi-touch, or linear — applied across all campaigns. Document the attribution model in the report methodology section.
Look for tools that integrate with your ESP and offer automated scheduling: Google Looker Studio (free, flexible, integrates with most platforms), PowerBI (enterprise-grade, integrates with Microsoft ecosystem), Tableau (best for complex visualisation), or each ESP's built-in reporting module (simplest, most accurate source data). The best tool is the one your stakeholders will actually use.
Quarterly is the standard cadence for executive reporting, with exceptions for critical periods (peak season, major campaign launches, deliverability crises). Weekly executive reports are almost never read. Monthly can work if the email programme is a significant revenue driver. Confirm the preferred frequency and format with the executive sponsor directly rather than assuming.
Good email dashboards prioritise trends over static numbers, use sparklines to show directionality, include contextual benchmarks (internal targets, trailing averages), use consistent colour coding (green for on-target, amber for at-risk, red for below-target), and surface the most important insight first. Limit each dashboard view to 5-7 metrics. Every chart or table should answer a specific question.
