Writing Successful Subject Lines

Thirty seconds on the clock, can you grab your reader’s attention? There’s a lot of competition out there. Inboxes are flooded daily with the latest sales, coupons, upcoming events, many of which will get deleted before they are ever opened. With so much competition, you don’t have much time to grab your reader’s attention as they filter through their inbox.

The best subject lines are short, simple and informative. Here is some advice to help you write more effective subject lines.

  • To lower your chances of triggering spam filters, avoid using sales phrases and the word “free.” In addition, using flowery words and punctuation will make your email more likely to be picked up as spam. A study from MailChimp went one step further and identified three words that may not necessarily trigger spam but negatively impact open rates. These words are: help, percent off and reminder.
  • Instead of trying to be flashy, be direct. Tell your readers exactly what they will find inside and make sure the message is directed at the target audience.
  • Keep it short and sweet. Don’t exceed more than 50 characters. MailChimp found that the most successful subject lines were between 28-39 characters.
  • Don’t stick to the same subject line. Change them up and keep them fresh in the effort to maintain readership.
