As you may know, the email subject line is the very first thing a subscriber to your email list will notice. This means that within 5 seconds per average, they will decide whether to open up the email or not. If the subject line is amiss, they will completely ignore your campaign.

Have you ever heard of the expression “The first impression is the last impression”? This is the case for the email subject lines.

It’s incredible how much power this one line has. It doesn’t matter how creative the content within the email is if you don’t get the subject line right. Let’s look at the numbers:

• The word “Sales” will increase open rates by up to 4%. The word “Sale” will decrease the percentage by 2%

• By including the subscriber’s name in the subject line, the open rates will increase by 29%

• Up to 60% of all email recipients will mark the email as spam based on the subject line

Additionally, it has also been noted that subject lines with 1 to 5 words, on average have an open rate of up to 16%, subject lines with 6 to 10 words have an open rate of 20%, and subject lines with 11-15 words have an open rate of 14%.

How to Craft a Subject Line

Just like email marketing best practices, there are email subject lines best practices. Regardless of the reason why you’re sending an email, it’s in your best interest to make the subscriber to read it.

When crafting a subject line, you should make sense of urgency. Make them believe that the content in the email is available for a limited time only. However, it’s essential to remember that too many such urgencies will send you straight to the spam folder.

Without a doubt, people love believing that they’re getting some deal. So, play this to your advantage. By letting the subscriber know of the deal within the email, they will check out the email to get more information.

You may have seen that some brands will ask you a question within the subject line. The reasons for this is because questions are a great way to get the attention of the recipient.

Nonetheless, it’s essential to understand that if you do this too often, your open rates will drop drastically. It has been noted that brands that have gone over the top have seen a lower click rate by 8% on average.

This means that it’s essential to pay attention to how you use it and how you formulate the question. If the subscriber has seen the question from you at 10 different subject lines, you will be perceived as a brand with no creativity.

Tips and Tricks

Keep it short – You should never write a subject line with more than 50 characters. The subject line should never be perceived as a vague message but more like a short and snappy phrase.

Attention Seeker – Perceive yourself as someone who is looking for attention when crafting them. The words that you include in the phrase are the sole persuaders to make a recipient to open the email.

Don’t Lie – There’s a difference between being creative and being a liar. So, in the subject line, you should never mislead the subscriber to open the email. This is the fastest way to lose value in the eyes of your customers.

Less is More

You already know that your subscriber will get hundreds of emails per day, every day. Thus, the majority of them are ignored or sent straight to spam. If you decide to leave the subject lines by chance, you will be another ignored email.

Even though such a feature must be made with creativity, they must be unique and engaging. Within a few words, you should persuade the subscriber that the content within the email is appealing to them.

A well-crafted subject line must be tested before you send it to the recipient.
