How to write great Email Subject lines

Email has become an important form of communication for marketers. At the same time (or maybe because of that) it has become increasingly difficult to stand out in a crowded inbox. The key to catching your recipient’s attention is to write great email subject lines and email preview copy.

Email subject lines best practices to increase your open rates and engagement

1. Keep the subject line short and sweet

The ideal length for an email subject line is around 6 to 10 words. Shorter subject lines are easier to read and grab the attention of your recipient. Make sure your subject line is concise and to the point.

2. Be specific

Your subject line should clearly convey what your email is about. Make sure it’s specific and relevant to your recipient. Avoid using vague subject lines that could be about anything. Make sure your main keyword is included in the subject line so people can easily understand what the email is about.

3. Personalize the subject line

Personalizing your subject line can increase your open rates. Use your recipient’s name in the subject line to make it more personal. You can also use other personalization techniques such as location, job title, or recent purchase history.

4. Add urgency

Creating a sense of urgency in your subject line can encourage your recipient to open your email. Use phrases such as “limited time offer” to create a sense of urgency. But be careful not to overuse this technique, as it can lead to fatigue and decrease your open rates.

5. Test and analyze

Testing different subject lines and analyzing the results can help you determine what works best for your audience. Use A/B testing to test different subject lines and see which ones have higher open rates. Analyze your results and adjust your strategy accordingly.

In conclusion, writing great email subject lines is a crucial part of email marketing. By keeping your subject lines short and specific, personalizing them, using urgency, asking questions, and using numbers or lists, you can create engaging subject lines that will increase your open rates and engagement.
