What is Email Open Rate?

Email open rate is the percentage of email recipients who opened a specific email in a campaign. It is one of the primary metrics in email marketing and gives you a quick indicator of how well your subject line and sender name are performing. A high open rate means your audience is engaged and interested in your content.

Formula:

Email Open Rate (%) = (Emails Opened / Emails Sent) × 100
Example: You sent 5,000 emails and 1,100 were opened: Open Rate = (1,100 ÷ 5,000) × 100 = 22%

Note: Many email platforms calculate open rate based on unique opens (not total opens, which count multiple opens by the same person).

How to Improve Your Email Open Rate

● Write better subject lines — keep them under 50 characters, use curiosity, numbers, or personalization

● Use a recognizable sender name — people open emails from people, not brands

● Send at the right time — Tuesday to Thursday, 9–11am or 1–3pm, tends to perform best (test for your audience)

● Clean your list regularly — remove unengaged subscribers to improve deliverability

● Segment your list — send more relevant content to smaller, targeted groups

● Use preview text — the first 50–100 characters shown after the subject line in most email clients

Frequently Asked Questions

● Q: Is a 20% open rate good?
● A: 20% is close to the average across most industries. Whether it is "good" depends on your specific industry benchmark and whether you are sending to a highly targeted list or a broad one.

● Q: How does Apple MPP affect open rate accuracy?
● A: Apple Mail Privacy Protection (2021+) pre-fetches email content, which triggers open tracking pixels even if the recipient never actually reads the email. This inflates open rates for lists with many Apple Mail users.

● Q: What is click-to-open rate (CTOR)?
● A: CTOR measures the percentage of people who clicked a link among those who opened the email. It is a better measure of content relevance than open rate alone. CTOR = (Clicks ÷ Opens) × 100.

● Q: My open rate dropped suddenly. What happened?
● A: Check if you were flagged as spam, if you changed your sender name or email address, or if your last campaign had unusually high unsubscribes. Also check if a major ESP update affected tracking.
