For many businesses, open rates have long been considered the most important e-mail marketing metric. After all, if someone opens your e-mail, that must mean the campaign is working, right? Not exactly.
While open rates are useful, they don’t tell the full story of how your audience is interacting with your content. Opens only show that an e-mail was delivered and possibly viewed, but they don’t measure what truly matters: whether people are engaging, taking action, and converting.
If you want to know whether your e-mail strategy is truly working, you need to additionally focus on metrics that measure engagement, conversions, and impact.
Why Open Rates Fall Short
Open rates only measure whether someone might have opened your e-mail, not what they did with it. They don’t show whether your message was actually read, if your links were clicked, or if the e-mail led to meaningful action. Relying too heavily on this one metric can give a false sense of success.
Key E-Mail Metrics That Actually Matter
1. Click-Through Rate (CTR)
CTR measures how many people clicked on a link in your e-mail. This tells you whether your content is engaging enough to inspire action.
Why it matters: Clicks are a direct indicator of interest in your offer or message.
How to improve it: Test calls-to-action, link placement, and e-mail design.
2. Conversion Rate
This tracks the percentage of subscribers who took the desired action after clicking, whether that’s making a purchase, signing up for a webinar, or downloading a resource.
Why it matters: Conversions tie your e-mails directly to business goals and revenue.
How to improve it: Align your landing pages with your e-mail content for a seamless experience.
3. Engagement Over Time
Instead of focusing on a single send, track how subscribers interact with your e-mails over weeks or months. Look at metrics like repeat clicks, ongoing interaction, and time spent engaging with your content.
Why it matters: Engagement trends reveal which subscribers are most loyal and which may be losing interest.
How to improve it: Segment your audience and personalize content for long-term value.
4. Bounce Rate
Bounce rate measures how many of your e-mails never reached an inbox.
Why it matters: A high bounce rate can hurt your sender reputation and deliverability.
How to improve it: Regularly clean your list and remove invalid or inactive addresses.
5. Unsubscribe & Spam Complaints
While no one likes seeing unsubscribes, tracking them helps you understand if your content or frequency is turning people away.
Why it matters: A sudden spike signals that your e-mail strategy may need adjusting.
How to improve it: Reassess your content value, sending frequency, and audience targeting.
6. Return on Investment (ROI)
Ultimately, ROI is the metric that proves whether your campaigns are profitable.
Why it matters: ROI shows the balance between the money spent on e-mail marketing and the revenue generated.
How to improve it: Track conversions carefully and connect e-mail platforms with analytics tools or CRM software.
Putting It All Together
When you shift your focus from open rates to a mix of metrics like CTR, conversions, and ROI, you get a far clearer picture of how your e-mails are performing. These KPIs don’t just tell you if someone glanced at your e-mail, they show whether your campaigns are moving your business forward.
E-mail marketing success is about more than getting people to just open the e-mail. By focusing on meaningful metrics like clicks, conversions, and ROI, you can understand the true impact of your efforts and refine your strategy for long-term growth. Open rate should not be ignored as it is still a metric to monitor, and may start the story, but it should never be the ending.
