80 Best Email Subject Lines for 2024

Do you want to get attention in your recipients’ inboxes? Do you want to increase opens and clicks? This guide will help you make great email subject lines.

How many emails do you get every day? If you are like most people, the number is between 30 and 70.

That is a lot of emails, and you cannot read them all. So, you probably look at a few and ignore the others, maybe forever.

What makes you open an email? It usually depends on three simple things:

  • The subject line.
  • The sender’s name.
  • The preheader.

This means that making these things better will help your email marketing.

In this guide, you will learn what you need to write subject lines and how to make the best email subject lines ever.

Here is what we will talk about:

  • What is an email subject line?
  • Why do email subject lines matter?
  • Tips for writing good subject lines.
  • 60 great email subject line examples.
  • Common mistakes to avoid in subject lines.

Why Are Email Subject Lines Important?

Your subject line can decide if your email campaign is a success or a failure. It is often the first thing your recipient sees, and if it is not interesting, it may be the last thing they notice. You can use AI tools to improve your email writing experience.

Statistics show that 47% of recipients open emails just because of the subject line. This means that the email body can be very good. However, if the subject line is weak, a lot of people might not open it.

It gets worse. Research shows that 69% of people decide if they want to mark an email as spam just by reading the subject line. Your subject line can be the only thing that stops your email from going to the spam folder.

Your subject line must also go through email service providers’ spam filters. These filters look for words or phrases that can be a problem.

In short, stronger subject lines can help your emails be:

  • More likely to get opened
  • Less likely to be marked as spam
  • This leads to higher click-through rates.

Crafting Effective Email Subject Lines

There is a skill to making subject lines that make people want to open your emails. We can write a whole guide about this. Maybe we will do that one day.

For now, we will look at four strategies that work. Use these in your next email campaign, and you may see better open rates.

1. Make it Irresistible

Your subject line must promise a good benefit. Think like your prospect. What do they really want? Can you give them that?

You must answer: What is in it for them? Why should they click on your email? Be clear and give them a reason to care about your message.

Examples of good subject lines are:

  • He makes $2000 per day alone (here is how)
  • How we got 2,300 subscribers in just days
  • You have a $100,000+ chance to make money

You can also make them curious.

The key is to create a curiosity gap. Give them some information but not all. This will make them want to know more. Asking interesting questions helps a lot. Here are some good ideas for email subject lines.

  • You can boost your productivity 5 times with this.
  • Life can be busy. I saved this for you.
  • Is this a magic writing tip?

But be careful with clickbait. Your email must have what the subject line promises.

If not, people may only open your email once. They could ignore your future messages or even unsubscribe.

2. Keep It Short

Short subject lines are very important. Many people read their emails on their phones. Long subject lines can get cut off. If this happens, your message can lose meaning.

Marketo did research. They found that the best subject lines had around 41 characters. In their study, the best subject lines had just 7 words.

3. Add Urgency

You can create urgency in your subject line to get more open. Saying something is limited can make people feel they might miss out.

Here are some time-based urgency examples:

  • Last chance for 6 months at $4.95 per month.
  • The flash sale ends now.
  • Only 90 minutes left.

You can also use inventory-based urgency:

  • Just 5 spots are left.
  • Selling fast.
  • Almost gone.

Be careful not to use urgency too much. Being too pushy can make people turn away. You do not want to be the brand that always says “final chance.”

Bonus Tip: Use a Strong Preheader

Make your subject line better with a strong preheader. This is a short text that appears after the subject line. It gives a preview of your email. It is a good chance to add more information.

Here is a great subject line and preheader example:

  • Subject line: Do you like it shirty?
  • Preheader: We thought so! Check out these 6 summer shirt must-haves.

How to Avoid Common Mistakes in Subject Lines

Many marketers and salespeople make the same mistakes when creating email subject lines. These mistakes can hurt your open rates. Here is a quick guide to help you avoid these mistakes:

1. Do not use words that go to spam.

Certain words or phrases can cause spam filters in email services like Gmail or Outlook. Whenever you can, avoid these words in your subject lines to make sure your emails reach the inbox. Many spam-related keywords belong to five main groups.

These groups are:

  • Exaggerated promises.
  • Unnatural phrases.
  • Artificial urgency.
  • Financial terms.
  • Suspicious or vague language.

To see a full list of spam triggers, you can look at our detailed guide. We have also created an online spam checker tool. This tool helps ensure your emails go to the right inbox and reach your audience.

2. Personalization Mistakes to Avoid in Subject Lines

Personalization mistakes can harm your subject lines. Personalization can improve open rates. However, if you do it wrong, it can cause the opposite result. Here is a common mistake to avoid:

  • Overdoing personalization: It is a big issue. Including the recipient’s name or personal details can increase engagement. However, using it too much can feel forced or not sincere. If you use someone’s name too often or in strange ways, it looks like you try too hard. This can make people feel uncomfortable. Keep personalization subtle and natural.
  • Incorrect or missing personalization tags: These are also a problem. Nothing ends an email’s impact faster than a subject line like, “Hey [First Name], check this out!” Always check your personalization tags. Make sure they show the correct data. If your system gets wrong or missing information, it can create an impersonal and awkward email experience.
