Tips for an Effective Subject Line

Email Marketing Getting Started Updated on November 11, 2020

The subject line of your email is one of the most important parts of email marketing. It is the first thing your intended audience will see and weighs heavily on their decision to open or delete your email. Following some simple tips will help ensure the best deliverability rates and boost your number of opened emails.

  • Keep It Short: You should keep your subject line to 55 characters or shorter. Most email clients, such as Yahoo, will cut a subject line that goes beyond 55 characters. You want your subscribers to see everything you have to say. Keep it short and avoid being cut off mid-thought.
  • Avoid Spammy Words: ISP mail filters identify several words and phrases as spam and will block your email if the subject line contains any of them. Many of them are obvious, such as “$$$,” Earn Extra Cash, and anything relating to Viagra or Cialis. However, there are other words that may pass filters but still damage the effectiveness of your campaign. A good rule of thumb is to use a subject line that you would open yourself, something that is not too flashy but raises some interest for the subscriber.
  • Ask a Question: By posing a question, it will make your audience curious and cause them to want to answer. If you can ask a question that will pull a “Yes” answer from them, that is even better. For example, asking “Did you enjoy running in the sprinklers as a kid to escape the heat of summer?” will not only help draw attention to your latest pool designs, but could cause your subscribers to recall more carefree days of childhood and thereby increase the odds that they will not only open your email but also make a purchase.
  • Make It a List: People are drawn to lists and a subject line that references one will draw in your audience’s attention. Saying something like, “Top 5 Flavors of the Year” for an ice cream company or “3 Favorite Winter Coats.”
  • Trial and Error: It will take a few campaigns to determine what works for your audience and what doesn’t. Try out different tactics with each email and then compare your reports to see which ones worked more efficiently than others. This will help fine-tune your approach and over time you will begin to see more and more open rates.

Using Emojis

In today’s world more and more people are using emojis to express themselves. Keep in mind not all subject lines will be fit for emoji use. If your message can be paired with emojis your audience might be able to relate better to your email, resulting in more opens.

Avoid replacing words with emojis. Instead, use them to compliment your text in case your chosen character doesn’t display in your recipient’s inbox.

It is recommended to always run a spam check on your campaign before you schedule it to determine the likelihood of successful delivery.
