The Best Email Subject Lines to Increase Opens Rate

Written by Viewed | Nov 10, 2022 3:06:06 PM

deally, your email marketing subscribers will visit your website, purchase your products, and share your content with their friends. But before any of that can happen, there’s a critical threshold you need to acknowledge: the open. If your subscribers never open your email, they won’t be able to take any action on it—rendering the email functionally useless.

In other words, your first and highest priority in email marketing is securing a higher open rate. With the latest email marketing trends emphasizing the importance of personalization, segmentation, and engaging subject lines, it’s crucial to stay ahead. Crafting better subject lines that align with these trends can make a significant difference—but what are the best subject lines for generating more email opens?

Why Are Email Subject Lines So Important?

For starters, an email subject line is the first thing your subscribers will see when reviewing your email. Before they read your message and even before they open it, the subject line will form their first impression. More than half of people will quickly delete most of the emails that hit their inbox simply because the subject line wasn't attractive enough.

It's also important to recognize that the body content of your email won't matter at all if subscribers never open your message. In other words, no matter how good your email is, the subject line is still the gateway that prevents people from viewing that excellent content.

To achieve higher open rates, it’s crucial to implement email marketing best practices when crafting your subject lines. An excellent subject line can yield good results even if your internal body copy is weak. Conversely, if your internal body copy is strong but your subject line is weak, it’s impossible to achieve adequate results.

The Qualities of Excellent Subject Lines

So what is it that makes a subject line effective? How can we tweak our subject lines to see better open rates across the board?

1. Conciseness

Whether you’re sending out welcome emails or a regular newsletter, it's important to keep subject lines concise. Email platforms limit the number of characters they display, and users often only glance at them. A strong, concise first impression with as few words as possible is crucial.

2. Uniqueness

Most people receive hundreds of emails daily, forcing them to delete most without a second thought. To stand out, your subject line needs to be unique and not a carbon copy of every other marketing email in their inbox. Thinking outside the box will help your email avoid the trash.

It's also important to recognize that different industries and different contexts require slightly different approaches to subject line optimization. The subject line that works well for an industrial manufacturer looks different than a subject line that works for a new college student.
