Hello, my fellow copywriters 👋

If you are wondering how to write your next email subject lines to ensure your readers open your email, you have come to the right post.

Today's post will discuss how to write an effective email subject line.

If there's one copywriting technique you must have in your copywriting arsenal, it has to be Curiosity Gap. I learned this technique from Justin Welsh.

Before we continue, you can read more of this post, where I detail how to make a YouTube headline that gets clicks.

The technique is called Curiosity Gap.

Curiosity Gap is about "I know something that you don't."

It creates a sense that you know all the answers that your audience doesn't, making them wonder what the answers would be. Hence, they are more likely to open your email.

Here are 5 tips on how you can implement your newsletter subject line:

1. Find your audience's pain point

Before creating a subject line, ask yourself:

"What pain point are you trying to answer?"

If you are working in at productivity space, the pain point might be:

"I find it hard to focus."

2. Hint a solution

After you've figured out the pain point, it's time for you to give a hint, not a complete solution.

You want to create a curiosity gap that makes your audience wonder.

You don't want them to know all the answers.

For example: "Use this simple step," "My proven framework to...," etc.

Those lines ensure you have something on your sleeve that you don't want to completely reveal to your readers until they open the email.

3. Use numbers

Numbers work like magic.

Your readers want some level of certainty.

Numbers give them a sense of certainty.

Your readers want something proven, not something that is still being experimented with.

Be sure to include numbers in your subject line.

4. Keep it short

Be clear and concise in what you put as subject lines.

Make sure it's under 50 characters or less.

Excessive words make the subject lines cut partially on mobile.

Put priority on making it shorter than you can think of.

5. Avoid spammy words

You don't want to use spammy words like "free," "guarantee," "cheap," etc.

Spammy words will more likely put your emails in the spam folder.

Better to avoid it.

Focus on value instead!

Example

These lessons will only be valuable if we take an example of how the subject lines sound.

Let's take a good example of subject line:

"Fix your focus in 5 mins using this simple step"

This example has all 5 frameworks that we have covered earlier:

So, it's time to try it yourself, and you will see your subject lines improve!
