An analysis of over 72,000 email campaigns reveals key insights into email open rates, showing a slight decline from a previous study. The study indicates that average open rates are around 12.3%, with a median open rate of 19.9%, suggesting that aiming for a 20% open rate is a reasonable target for above-average campaigns. Subject line length and the volume of emails sent appear to influence open rates negatively, with shorter subject lines and more targeted demographics generally performing better. Certain terms in subject lines, such as "congrat" and polite phrases, have a positive impact on open rates, while emojis and overly long subject lines tend to underperform. The research also highlights that the timing of sending emails throughout the week has minimal impact on open rates, emphasizing that a well-crafted subject line is more critical to campaign success.
