What Is Open Rate?
Quick Answer
Open rate is the percentage of recipients who open an email out of everyone it was sent to — a basic engagement metric for email marketing, calculated as opens divided by emails delivered.
Open Rate vs. Click-Through Rate — What's the Difference?
| Open Rate | Click-Through Rate | |
|---|---|---|
| Measures | Whether the email was opened | Whether a link inside it was clicked |
Why Does Open Rate Matter for a Small Business?
- It's an early signal of whether your subject lines are compelling enough to earn attention.
- A consistently low open rate often points to list quality or sender reputation issues, not just weak subject lines.
How Is Open Rate Calculated?
Open Rate = (Emails Opened ÷ Emails Delivered) × 100.
Key Takeaways
- Open rate measures whether an email was opened, not engaged with further.
- 20-30% is a commonly cited healthy range, used as a guide not a hard target.
- Privacy features have made the metric somewhat less precise recently.

Frequently Asked Questions
What's a good email open rate?
Averages vary by industry, but 20-30% is a commonly cited healthy range for small business email marketing — treat it as a general guide, not a strict target.
Why might my open rate be inaccurate?
Modern email privacy features (like Apple Mail Privacy Protection) can artificially inflate open rate data, making it a less precise metric than it used to be.
How do I improve my open rate?
Write more specific, curiosity-driven subject lines, and keep your list clean of inactive addresses that drag down your average.
