102 email subject lines that work

Did you know that people receive an average of 121 emails each day? From brand marketers to co-workers, there is no shortage of people competing for attention in your customers’ inboxes.

The reality is your customers live busy lifestyles. They don’t have the time (or desire) to read every single email. That’s why they glance at the subject line to decide if an email is worth opening.

The good news is email continues to be a powerful marketing channel for companies in the home service industry. Here’s why:

But it’s not enough to send just any email to your customers. Your goal is to create email subject lines that work.

Why your emails need good subject lines

Think about how you manage your email account. When you open your email and stare at dozens of messages, how do you decide which ones to read?

If you’re like most people, the first thing you do is scan the subject lines for a few seconds. You read the emails with subject lines that grab your attention and leave the rest unopened.

When it comes to opening emails, your customers are just like you. They are attracted to subject lines that stand out from the rest. That’s why it’s essential to make subject lines a part of your marketing strategy to increase your email open rates. (For ideas on how to get more opens on your marketing emails, check out this post with email marketing tips.)

Customers open emails for a variety of reasons. A common reason is the fear of missing out (FOMO). Email subscribers don’t want to miss any important details from promotional emails, like coupons or discounts. So, it benefits your home service business to write email subject lines that work. 

Good email subject lines help deliver your company’s marketing message to your email newsletter list and grow your customer base. With the many emails people receive, standing out with a solid subject line is crucial to getting them to open your email. 

Email should be a 1-1 relationship between you and your customer. The more you can dial in your email subject line and copy, the greater chances are that your customer will take action. 

Here are some of our favorite email subject lines.
