We’ve created these 8 fundamental points to make writing effective email marketing subject lines quick and easy.
The Self-Interest Email Subject Line
These are your bread and butter subject lines—you should be using them most frequently.
They are usually direct and speak to a specific benefit your audience will gain by opening the email.
Self-interest subject lines also help pre-qualify openers by giving them a clue about your email’s body content.
If self-interest subject lines work because they communicate a direct benefit, curiosity-based ones succeed for the exact opposite reason.
They pique the interest of subscribers without giving away too much information, leading to higher opens.
Be careful though, because curiosity-based subject lines can get old fast and are the most likely to miss their mark.
Do you like free stuff? Do you like to buy things when they’re on sale?
So does your email list.
When you are giving something away or selling something your subscribers would be interested in, directly stating that in your subject line is a great way to convince them to open the email and learn more.
Urgency/Scarcity Subject Line
This is the most powerful type of subject line you have at your disposal.
Subject lines that communicate urgency and scarcity tell readers they must act now.
But too many of these can lead to list exhaustion, so use sparingly and, of course, only when there is truly a deadline, limited quantity, or limited availability.
Humanity Email Subject Line
Don’t forget to remind your list about the person or people behind your products.
Sometimes you need to thank your subscribers, tell them a story about yourself, or make a human appeal for their attention.
Keeping your audience informed about new developments in your field builds authority and keeps your open rates high.
These subject lines often work well when combined with a curiosity element.
Social Proof Email Subject Line
A fundamental characteristic of humans is that we look to the behavior of others when making decisions.
You can leverage this in your email subject lines by mentioning individual’s success stories, familiar names, or highlighting how many people are already using a product or service.
The Story Time Subject Line
Telling a story, or at least teasing the beginning of one in your subject line is a unique way to highlight benefit and get the open rate you’re looking for.
