Zack Greenfield • March 28, 2018

With inboxes getting inundated with emails from every imaginable organization, businesses have to think hard and fast about getting the attention of their target customers so that they will have a much higher chance of their emails getting opened and read by their target audience. Here are 10 strategies that you can use on your subject lines to help guarantee your target customers will open your emails.

Point an information gap.

Everybody is technically doing the same thing, yet there are those who simply do it better. Give them a promise that they truly desire and point out a gap in information and you are guaranteed to have about 41.59% of your emails being opened.

Write something controversial.

Man is classically intrigued by conflict and controversies. Just look at social media platforms and you can see a lot of folks arguing. Get your readers to pick their side. If you can do this, you’re guaranteed about 41.49% of your emails being opened.

Use the “some… while others” technique.

People naturally would want to know why some are more successful at doing certain things than others. It arouses curiosity and plays to the reader’s innate desire to become better. This technique can guarantee you an email open rate of nearly 41.49%.

Use proclamation headlines.

Using big and bold statements that can sometimes border on being offensive is sure to grab attention. Unfortunately, you have to be very careful in phrasing your line as people don’t like being insulted. Address your proclamation in the general sense and not directly to your email recipient.

Be realistic about using the word “extraordinary”.

Be careful when using the word “extraordinary”. It may get almost 38% of your recipients to open your email but it could easily backfire if you fail to substantiate your claims of ‘extraordinariness’.

Think about before-and-after scenarios.

People love to know how a particular problem was solved or how a certain activity progressed over time. If you can communicate this in your subject line, then you’re guaranteed on open rate of more than 37%.

Arouse your reader’s curiosity.

There are certain words that can really work like magic. For example, using the word “weird’ will have people naturally thinking what is weird with what you have. Curiosity will drive more than 37% of your target audience to open your email.

Write something they can relate to.

The key here is to find meaningful words that you can use during special occasions. For instance, you can simply write “Freedom!” in your subject line during the annual Fourth of July celebrations since everyone will be talking about independence and freedom.

Tell them like it is.

What you want to achieve is for your reader to think whether it is worth checking out what you have made for them or not. For example, you can write in the subject line “They asked me to give them tough love. I did. And it’s on video.”

Identify the right promise to give to your reader.

If you can create a very realistic and very specific promise to your reader, then there is a 35% chance that your email will be opened and read. For instance, you can write “How to make other people like you in 10 seconds max.”

It’s not easy to make subject lines that will grab your reader’s attention. But if you can find the right formula, then email marketing has just become a lot easier.
