Email marketing statistics

Why monitor email marketing statistics?

Email marketing remains one of the most effective channels digital marketers have available. Tracking the right email marketing statistics gives you clear insight into how campaigns are performing and where to improve ROI. By monitoring engagement signals like opens, clicks, unsubscribes, and bounces, you can create targeted content that consistently meets your marketing goals.

How to choose the right email marketing metrics

With so many available metrics, narrowing your focus is essential. The data you track should be high-level, actionable, and easy to read, and it should support direct comparison across campaigns. Here are the email marketing KPIs and metrics every digital marketer should monitor.

Email marketing statistics KPIs

Campaign Performance

Campaign Performance is a reliable way to evaluate whether an email campaign is working, and what to do next, whether that means improving the email and related landing pages, building similar campaigns, or discontinuing the campaign entirely.

Why this metric?

Campaign Performance gives digital marketers a clear view of how each email marketing campaign is performing. It captures the reach of the email, the effectiveness of the subject line, actions taken within the email, and the number of unsubscribes prompted. This makes it easier to measure, compare, and act on campaign results. You can explore a ready-made campaign performance dashboard to visualize these results at a glance.

Delivery and Engagement Statistics

The Delivery and Engagement Statistics metric gives digital marketers a high-level view of campaign performance. It shows how many leads received the email, how many opened it, and how those who opened it interacted with the content.

Why this metric?

Delivery and engagement statistics reveal whether your subject line and content are compelling enough to drive action. Beyond open rate, this metric shows how recipients engage once inside the email. Reviewing these statistics alongside the actual campaign structure helps marketers refine current campaigns and build more engaging ones going forward.

Opens by Country
