What Is Open Rate? Definition, Importance, and Improvement

What is Open Rate?

Open rate is the percentage of email recipients who open a specific email compared to the total number of emails delivered.

Formula for Open Rate:

Open Rate = (Number of Opens / Number of Delivered Emails) x 100

👆 Fun Fact: The first email marketing blast was sent in 1978, but open rates weren’t trackable until HTML emails became popular in the late 1990s. Today, open rate is one of the most watched metrics in email marketing!

Understanding open rates is crucial because:

Indicates subject line effectiveness: A strong subject line can significantly boost open rates.
Shows email timing success: Tracks whether you’re sending emails at the optimal time.
Measures audience engagement: Reveals how interested your subscribers are.
Guides email list maintenance: Helps identify inactive subscribers.
Affects other email metrics: High open rates often lead to higher click-through rates.
