How to calculate your email open rate (plus tips for improving it)

Email campaigns are a vital marketing strategy used to engage with both potential and current customers, aiming to maintain interest, reengage previous clients, and attract new leads. A key metric in evaluating the success of these campaigns is the email open rate, which indicates how many recipients opened the message and provides insights into audience engagement and the effectiveness of marketing strategies. For example, A/B testing with different subject lines can reveal which approach generates more interest and higher open rates. The average open rate varies across industries, with religious emails having the highest rate at 44%, while electronics emails have the lowest at 27%. To calculate the open rate, subtract bounced emails from the total sent, divide the number of opened emails by this adjusted total, and multiply by 100 to express it as a percentage. Understanding and improving email open rates can significantly enhance the impact of email marketing efforts.
