Tips for Email Subject Line Testing

Here are some tips to help you get started with email subject line testing to boost your email open rates. 

  1. Use A/B Testing
    A/B testing is a method where you send two versions of your email to a small subset of your email list. Each of them contains different subject lines. The results are analyzed to determine which subject line performs better. The winning subject line can then be used for the rest of your email list. A/B testing is an excellent way to find out what works and what doesn't work for your audience.
  1. Keep it Short and Crisp
    A great subject line should be concise and to the point. Most email clients snip subject lines that are too long. Hence, it's important to keep them brief. A good rule of thumb is to keep your subject lines around 50 characters or less. This ensures that your subscribers can read the entire subject line, even on their mobile devices.
  1. Personalize Your Subject Lines
    Personalization is a great way to make your subscribers feel valued and increase your open rates. Use your subscriber's name or other personal information to make your subject line more engaging. For example, "Mark, don't miss out on our latest offer" is more personal and engaging than a generic subject line like "Our Latest Offer."
  1. Use Urgency or Curiosity
    Creating a sense of urgency or curiosity in your subject line can increase open rates. Make use of phrases like " Here’s the Last Chance" or "Do not Miss Out" to create a sense of urgency. Use phrases like "Find Out" or "Discover Secrets" to pique your subscribers' curiosity.
  1. Test Different Types of Subject Lines
    Different types of subject lines can resonate with different audiences. Experiment with different types of subject lines, such as questions, lists, jokes, or puns, to see which ones perform best.

Analyze your email campaign metrics to discover the optimal times for sending emails to your audience. Consider time zones and the recipient's work schedule when determining the best time to send.

    Use analytics tools to track your open rates and analyze the success of your subject line testing. Use the data to adjust your strategy and improve your open rates over time. By analyzing your data, you can gain insights into what works best for your audience and continually improve your email marketing campaigns.
