Do you know how important subject lines are? A recent study from Optinmonster found that almost half (47%) of email users will open your email based on just the subject line alone. By amending your subject lines you could see a dramatic increase in opens as this statistic shows. This goes to show just how important your subject line is. Sometimes your sender name isn’t enough to get subscribers to open your emails.
Your subject line plays a key part as to whether or not subscribers open your emails. So it’s important that you are making the users aware of what content is inside the email from the subject line. In order to improve the open rate solely from the subject line, ensure that you take the time to split test subject lines and make them tailored to the consumer by adding different personalisation such as age, location or notable events such as a birthday or anniversary.
