Use compelling subject lines. An email subject line that is clear and compelling gives your email better visibility in a crowded inbox. Incite your recipients to open your message with a call to action in the subject line. A generic header such as “June Newsletter” doesn't intrigue as much as something like "Purchase within five days for 10% off your graduation gifts." Just be sure you don't use words like “free,” “limited time offer,” or “amazing” in your subject line. These are red flags for spam and will cause your unopened email to go directly into the trash folder. Get the full story at Direct Marketing News
