What is a benchmark in email marketing? 

In simple terms, an email marketing benchmark is an overall performance chart, evaluation and finding improvements on email marketing kpis.

It is a standard or average number that defines whether your email campaigns are performing well, average, or poorly compared to other businesses in your industry.

Think of it like a health checkup for your inbox strategy.

If the average open rate in your industry is 35% and yours is only 15%, the benchmark tells you that your subject lines or your sender reputation need work.

Why is email marketing benchmarking important?

Email marketing benchmark is a helping hand to your email marketing agenda. While you are taking steps to evaluate marketing reports, benchmarking widens the possibility of digging through email marketing.

Take a look at more significances here. 

1Provides a reality check

Benchmarks act as a neutral third party. It’s easy to feel good about a 20% open rate until you realize your direct competitors are hitting 40%.

• The benefit: They help you set realistic goals. If the industry standard for a welcome email is an 80% open rate, you know that your 50% rate means you are leaving significant money on the table.

2Identifies technical invisible problems

Sometimes, your content is great, but your technical setup is broken. Benchmarks help you spot these unseen technical issues –

• The signal: If your bounce rate climbs above 2%, benchmarks tell you that your email list growth rate is decaying or your sender reputation is at risk.
• The consequence: Without knowing the benchmark marketing, you might keep sending emails that are being blocked by Gmail or Outlook filters without you ever realizing it.

3Justifies your marketing budget (ROI)

If you need to ask for more budget for an email tool or a copywriter, benchmarks provide the essential data about –

• The stat: Knowing that the 2026 global benchmark for ROI is $36–$42 for every $1 spent allows you to prove to stakeholders that email is a high-value investment compared to more expensive channels like paid search or social ads.

4Directs to take potential steps

Benchmarks for Click-to-Open Rates (CTOR) tell you if your audience is getting bored.

• The insight: If your Open Rates are high (people like your subject lines) but your CTOR is falling below 10%, the benchmark signals that your inside content is no longer providing value. It’s time to refresh your design or offer.

5Guides AI & automation strategy

In 2026, most platforms use AI to optimize send times.

• The use case: Benchmark metrics tell you the standard for automated vs. manual performance-based email marketing. If your automated abandoned cart flow can’t reach at least $3.00 for every subscriber, you know your AI isn’t operating correctly for your specific audience.

Summary: key statistics

• Average ROI: $36-$42 for every $1 spent
• Global email users: 4.97 billion expected by 2028
• Daily email volume: Over 408 billion messages projected by 2027
