Why Email Open Rate Is Important

Why does Email Open Rate matter? Typically, engagement equals connection. When emails get opened, it signifies that the content speaks to the audience, resonates with their interests, and sparks their curiosity.

Opening Connections to Additional Metrics

How Email Open Rate Relates to Other KPIs

Understanding the connection between Email Open Rate and other metrics is the key to optimizing email campaigns and achieving tangible results. For example, after the email is opened, Click-Through Rates and Conversion Rate metrics help to deliver a more complete picture of the campaign’s success.

Email Open Rate is also connected to Bounce Rate. A high Email Open Rate, along with a high Bounce Rate suggests problems with the email list quality. Keeping a clean list ensures messages reach the right inboxes. 

Revenue and ROI are everything and are critical ways to showcase agency value to clients. Keep in mind that a high open rate is promising, but it doesn't guarantee success. Agencies use these email marketing metrics together to fine-tune strategies for better results and make connections to what impacts a client’s bottom line.

Understanding Unique vs. Total Opens

Unique opens and total opens are critical metrics in email marketing, each providing distinct insights into how recipients engage with emails. Unique opens count the number of individual recipients who open an email, regardless of how many times they do so. This metric is essential for assessing the initial reach of an email campaign, as it shows how many different people are viewing the content.

Total opens, in contrast, track all instances of an email being opened, including repeated views by the same recipients. This metric indicates the email's ability to engage and retain the audience's attention. A high ratio of total opens to unique opens suggests that the content is compelling enough for readers to revisit.

Other Impactor KPI Factors to Consider
Judge your results against your own criteria. Consider what your brand is about and what its objectives are for email communications. Any metric can be gamed for perceived improvement, and if you just want a higher open rate, you can sensationalize headlines or create clickbait headlines, but if that’s not aligned with your brand and its objectives then what’s the point?

What Is a Good Email Open Rate?

A good average Email Open Rate typically hovers around 20-25%. However, this varies depending on the industry average and audience. Some industries, like non-profits, may see higher rates, while others, like eCommerce, might aim slightly lower. Keep an eye on the specific niche for more accurate benchmarks.

What Is a Bad Email Open Rate?

A bad average Email Open Rate is generally below 10%. It suggests the emails struggle to capture the audience's attention. However, it's crucial to consider unique circumstances. If emails consistently fall below industry averages, it's time to reassess the email marketing strategy.

How To Set Email Open Rate Benchmarks & Goals

Use historical data to establish email marketing benchmarks specific to clients. Analyzing past email campaigns' performance, segmenting the audience, and considering seasonal trends help create more tailored expectations.

To gain deeper insights into Email Open Rate, consider segmenting the audience. Compare open rates for different demographics, locations, or interests. This granularity uncovers hidden opportunities and helps refine an email strategy.

Why Email Open Rate Matters to Clients

For clients, Email Open Rate is a great KPI to gauge audience interest and content relevance. If an email is opened, it’s the initial nod of approval from the recipient.
