Email Subject Line Best Practices to Keep in Mind While Crafting An Email

  • Write multiple subject lines and then choose the best one .
  • Keep your subject lines short i.e. limit the characters upto 33 including spaces or keep it between 4 - 7 words. Subject lines with less than 50 characters have higher open rates and click-through-rates than those with 50+.
  • More caps doesn't mean More opens : Covering your subject line in caps doesn't help at all. Rather it is at times difficult to read.  Use them sparingly and responsibly.
  • Know your audience : The best way to create a good email subject lines is how well you understand your audience intimately. Matching your audience’s interests and mannerisms is essential if you really want solid open rates.
  • Use a conversationalist tone : Most good email subject lines rely on a conversationalist tone to attract readers.
  • Call to action : It’s never a bad idea to try a call to action in your email subject line. While many opt-out due to limited character space, call to actions may improve open rates.
  • Using You/Your. While name-calling is on the out, it’s still considered a best practice to use “you” and “your” wording to speak directly and comfortably with readers.
  • Put Yourself in the “From” field. People like to communicate with an individual entity. Users would want to see that they are communicating with a legitimate and trusted source.
  • A/B test your subject lines : You should A/B test everything about your email copy, email subject lines included.
  • Pay attention to the preview. The email preview that follows the subject line is a valuable piece of property, and yet so many businesses ignore it.
  • If you see great subject lines that you think will work for your business, nab them! Tweak them a bit and try them on for size. Remember, imitation is flattery, so flatter the hell out of the best email subject lines.
