With a strong subject line you can make the difference between actually connecting with the consumer or becoming spam.
Here are some tips to make your subject line and email opener no matter what:
Keep it short and sweet. Shorter subject lines generally have higher open rates than long ones. And while there's no magic length, Internet Service Providers (ISPs) sometimes truncate subject lines, so keeping them under 50 characters will help you avoid getting cut off. With ExactTarget Email, you can test your subject line among different ISPs to make sure it renders correctly.
Show your style. Subject lines are meant to be persuasive, so don't settle for a boring message. Instead, make it personal and infuse your brand style into the one-liner. You can also appeal to emotions with a time-sensitive call to action. Just be sure that the subject still tells the reader what they're in for.
Test, test, and test again! The best way to find out which subject lines resonate with your audience is to regularly test different variations. With ExactTarget, you can easily test your subject lines using A/B testing. You'll see how real subscribers respond to different subject lines according to the open rate. Be sure to test various lengths, personalization, and styles to determine what motivates your readers.
So don't forget to keep testing for the strongest subject lines. Something that worked last spring may not work as well this summer.
