50+ Best Email Subject Lines of All Time

An email subject line is the first point of contact you have with your readers. It’s their first impression and often the deciding factor if they open your message.

The good news is, writing subject lines that win people over is a skill you can learn and practice. Every subject line you write should be focused on helping your reader.

What is the subject line?

A subject line is the introduction that defines the emails purpose. This subject line, shown to the email user or receiver as they look at their list of messages in their inbox, should inform the recipient what the message is about, what the sender wants to convey.

There is a common misconception that you should make efforts while writing the body of your email. After all, the body is where you can expand on the content and reflect on it. However, the subject line of an email is as important as the body.

In this blog, you will learn the following things through examples:

Adding some humor to your subject lines can increase your CTR.
If you have a long subject title, break it up to make it more interesting.
The subject line is the first thing the recipient sees, make sure it’s great.
Your subject line is the first impression for your email campaign.
Make your subject lines goal oriented and short.
Use active voice and present tense to make your subject lines more dynamic.
Subject lines can also be a call to action.
Make your subject lines relevant to the content of your email.

There’s a lot to be said for brevity: being clear and concise saves time for your users. Let’s know more about this in details.
