If you want to know what makes a good email subject line, you’ve come to the right place. Discover the top 11 email subject lines here.

What Makes a Good Email Subject Line?

A good email subject line can act as an anchor for the rest of the email. As a result, people will be more likely to read your message, especially if the subject is intriguing. To take your email marketing efforts to the next level, you’ll want to create a subject line that will captivate your reader. While it might seem difficult, there are a few guidelines to follow to make sure you get this right each time.

For one, it’s important to inject some personality into the subject line. People respond better when you have a little bit of fun with it. Also, you can include certain keywords. This will help people who receive an inbox full of emails to figure out whether they want to open yours or not.

But the most important thing is to make the subject line short, sweet, and to the point to grab the receiver’s attention.

If it’s not interesting or catchy, then they might just skip over it. Try to avoid using words that are too specific or technical. If you’re promoting a product, you might use the product name in the subject line, but this might not apply to all products. The most important thing to remember is to keep it simple and concise so that it’s easy for your recipients to understand.

Tips to Write the Best Email Subject Line

Create a sense of urgency.

You can show urgency in your subject line by making the reader feel like they need to see what’s inside the email or they will miss out on something big. You can also use time-sensitive phrases that let the reader know if they don’t use a certain service or buy a product soon it will be too late. However, be careful not to scare the reader as you may end up leaving a bad impression.

Make it specific to the receiver.

The receiver is the person who you think will benefit the most from the content. This can be a certain demographic or group of people. It’s all about the user experience and how you can improve it for the receiver. People will take the time to read your content and engage with it if it’s relevant to their needs and interests.

Keep it short and simple.

If your subject line is too long, then you’re going to have a hard time getting your audience to notice it, let alone click on it. Keep it short and simple. Your subject line should be between three to four words. A subject line that has too many words makes it look like an advertisement, and won’t draw anyone in because they won’t bother reading the rest.

Keep it open ended.

Keeping an email open-ended and very general in your subject line can be a great way to get your reader’s attention. People get a lot of emails every day and a subject line that says something like “Job Interview Question: The worst thing a boss has ever said to you” will catch a person’s eye right away!

Avoid spammy words.

It’s important to get to the point if you want someone to read your message but general subject lines can help people discover what your email is all about. Of course, you also want to be sure that the subject line isn’t spammy. A simple rule of thumb is to keep it to one idea and about 100 characters.
