No matter what they say, people do judge a book by its cover and the same implies for emails. Writing catchy email subject lines is the key to getting more recipients to read your emails. Around 300+ billion emails are being sent/received each day and only 21.33% of them are opened. So, the chances of your email being ignored are pretty high, unless you boast a super-duper catchy subject line!


One research reveals that 33% of email recipients open emails because of catchy subject lines. While the subject line might seem like a small part of your message, it can do wonders for you. As it is your first (and probably your last) impression on the reader, it can help you stand out in the crowded box.

After all, there’s no point in perfecting your email copy, if it never sees the light of the day. Let’s look at 8 recommendations to help you design interesting email subject lines that will get your emails to open!


8 Tips For Writing Catchy Email Subject Lines:

1. Maintain a Short and Sweet Approach:

In today’s era, where a user’s attention span is less than that of a 1-year-old child, keeping your subject line simple and crisp is the key. Hefty email subject lines often get cut off, so try to keep your subject line with fewer than 60 characters.

Since 46% of emails are opened on mobile devices this technique can be a game-changer. 

For example, If you’re a B2C business and send an order confirmation. Instead of saying, “Your Order #947362849674 is being processed”, say “Your order is being processed”. 

This will not only help you keep your subject line minimalistic but also increase the chances of email getting opened. The same applies to personal emails or marketing emails as well. 


2. Try Some Puns:

Most people love puns. It’s a great way of bringing a smile to your recipient’s face. If you’re a B2B marketer or a salesperson, trying some puns can bring life to a dry and dull email. The key is to not overdo it and slip them in the right place.

Although do remember that not everyone likes it and can be a bit troublesome when trying to reach the masses. However, if you know your audience well and the email is being targeted, a well-placed pun can make your regular subject line into a catchy email subject line. 


3. Use Personalisation:

Incorporating personalisation into your email subject lines is a great way to get your emails opened. Everyone loves the sound of their name and when someone calls out, it gives them a sense of belonging. This helps in building brand loyalty.

According to research, emails that have the first name in the email subject lines, have higher click through rates, than emails that did not.

The following is an excellent example of how brands use this information in email subject line

Use Personalisation

That’s great personalisation, as it creates a sense of belonging and curiosity at the same time. 

In such a way you can use the tokens of personalisation and give a good sense of engagement to your customers. Just be careful not to overdo it with personalisation. That can be a little unsettling.

4. Give Exclusive Offers:

The psychology of exclusivity is a powerful thing, so use it to your advantage.

Try to phrase your email subject lines to make your recipients feel special and valued. Humans are much more inclined to offer especially when it’s exclusive and just for them.

5. Create A Sense of Urgency:

Creating a sense of urgency is an efficient way to get people to take action. Unless people find a deadline, they don’t feel the compulsion to act on it, therefore you can take this to your advantage.

All you need to do is, phrase the email subject line, with words like, “limited” or “ Just for today”. The receiver will be compelled since they will realise that the offer will not be extended indefinitely. As a result, they will be urged to open the email and read the offer.

 An example below shows, how IndiGo creates a sense of urgency. 


Just make sure that you’re not sending such emails regularly, otherwise, it will feel spammy and the exclusivity will vanish. Few more examples of how Ellipstore creates a sense of urgency:

6. Use Emojis:

In the inbox full of text, making your email stand apart might seem like a challenging task. That’s where emojis come into play. You can use emojis in your email subject line and make it stand apart.

According to Experian, 56% of brands that use emojis in their email lines had a higher open rate. As a result, including an emoji in your message will stand out in the recipient’s inbox and grab their attention.

Isn’t it the one with emojis in the subject lines? Well, this proves that emojis are an effective way to hook your audience using just your catchy email subject line. They may help you express more content and emotion with minimal text. Thus, helping to convey your message better. 


7. Put Numbers in the Email Subject Lines:

Incorporating digits in your email subject lines will attract attention, as our brains are naturally drawn towards numbers.

8. A/B Test Your Email Subject Lines:

 Last but not the least. A/B test your email subject lines. The above tips and email practices are great to start with, but what works for one company, might not work for you. 

 As we all know there is no “one-size fits all” strategy, therefore it is necessary to A/B test your email subject lines. Experiment with alternative words and phrases, emojis with or without, question vs. statement, personalization, subject line length, and any other element that could affect performance.

 To decide which version was the most effective, compare open rates, clicks, and even conversions from your experiments.
