How to Write Email Subject Lines that Get Opened: A Small Business Guide

We’ve all been there: staring at a blinking cursor, trying to come up with the perfect email subject line that will make people stop, click, and open. It’s a tricky business, especially for small business owners who are juggling so much already. But here’s the good news: creating subject lines that get noticed doesn’t have to feel like guesswork. With a little strategy, a pinch of creativity, and a few insider tips, you can craft subject lines that actually get people excited to open your emails. Let’s dive in and uncover what works, what doesn’t, and how you can start seeing better open rates today.

Why Your Subject Line is More Important Than You Think

Think of the subject line as the doorman to your email. If it’s friendly, intriguing, or promises value, people are way more likely to “walk in.” But if it feels generic, overly salesy, or spammy, it’ll probably get ignored. For small businesses, every email counts—whether it’s driving traffic to your website, announcing a sale, or building a stronger connection with your customers. Your email subject line is the first impression that sets the tone for what’s inside. So, nailing that small but mighty piece of text can make all the difference in your email marketing success.

What Makes a Great Email Subject Line?

Here’s the thing: a great email subject line isn’t one-size-fits-all. It depends on who your audience is, what you’re offering, and the tone of your brand. But some key elements are universal. To get people to click, your subject line should be:

1. Personalized – People love emails that feel like they’re written just for them. Using a customer’s first name or referencing a past purchase can instantly make your subject line more appealing.
2. Urgent – FOMO (fear of missing out) is real! Creating a sense of urgency with words like “limited-time offer” or “don’t miss out” encourages quicker action.
3. Curiosity-Inducing – People love surprises. If your subject line teases just enough information to spark curiosity, it can lead to more opens.
4. Clear and Concise – You want to grab attention, but you also want people to know exactly what they’re opening. Be clear about the value of your email while keeping it short.
5. Mobile-Friendly – Keep in mind, a huge chunk of your audience is checking emails on their phones. Aim for subject lines with 6-10 words so they don’t get cut off on smaller screens.

How to Write Irresistible Email Subject Lines

Let’s break down some easy-to-follow strategies for crafting subject lines that make people stop scrolling and start clicking.

1. Get to Know Your Audience

The more you understand your audience, the easier it is to write subject lines that speak directly to them. Are they casual shoppers, loyal customers, or professionals looking for solutions? Tailor your language and tone to fit their vibe.

For example:

• For a younger, trend-focused audience: “Hey [First Name], Don’t Miss This Exclusive Drop!”
• For a more professional crowd: “[First Name], Here’s Your Invite to Our Webinar on Industry Trends”

By speaking to your audience’s specific needs and preferences, you’re already halfway to getting their attention.

2. Use Action-Oriented Words

Subject lines should inspire action. Rather than stating what’s inside the email, focus on encouraging the reader to do something. Words like “explore,” “discover,” “grab,” or “join” create a sense of movement that can lead to more opens.

Examples:

• “Discover the Secrets to Growing Your Business”
• “Grab Your 10% Discount Before It’s Gone!”

3. Create a Sense of Urgency

Urgency works because no one wants to feel like they’re missing out on something valuable. You can create urgency with time-sensitive offers or highlighting limited availability. Just make sure it’s genuine—using fake urgency too often can harm trust with your audience.

Examples:

• “Flash Sale: 24 Hours Only!”
• “Only 3 Spots Left – Book Your Consultation Today”

4. Personalize When You Can

Adding a personal touch to your subject lines can make a big difference in open rates. People are much more likely to engage with something that feels like it’s meant just for them. Even small bits of personalization—like their name or location—can catch their eye.

Examples:

• “Hey [First Name], Your Special Offer is Waiting!”
• “An Exclusive Deal for [First Name] – Shop Now”

If you know your customers’ preferences or purchase history, use that information to make your subject lines even more targeted.

5. Skip the Spammy Phrases

Certain words and phrases are a surefire way to get sent straight to the spam folder. Words like “free,” “guaranteed,” or “act now” are often overused and trigger spam filters. Instead, try to focus on creating genuine value in your subject line.

Examples:

• Instead of “Free Ebook,” try “Get Your Complimentary Guide Today”
• Instead of “Act Now,” try “Secure Your Spot Before It’s Gone”

By steering clear of overly pushy language, you can maintain a more trustworthy and authentic relationship with your audience.

6. Use Numbers and Lists

Numbers work because they give people a clear idea of what to expect. Whether it’s “5 Ways to Improve Your Business” or “3 Tips for Better Mornings,” numbers offer a sense of structure and value.

Examples:

• “7 Tips to Boost Your Online Sales”
• “3 Easy Steps to Improve Your Email Open Rates”

Lists and numbers are also great for readers who like to skim through content quickly, which makes them even more appealing.

7. Test and Tweak

One of the best ways to improve your subject lines is through A/B testing. This means sending two different subject lines to small groups within your email list and seeing which one performs better. Over time, you’ll start to notice patterns in what works and what doesn’t.

You can test things like:

Subject line length

• Tone (friendly vs. formal)
• Use of urgency or personalization

The more you experiment, the better you’ll understand what resonates with your audience.

Best Practices for Small Businesses

When it comes to small businesses, your email subject lines are more than just a tool for better open rates. They’re part of how you communicate your brand’s personality and build relationships with your customers. 

Here are a few additional tips to keep in mind:

• Be Consistent with Tone: If your brand voice is friendly and casual, keep your subject lines in line with that. A sudden shift to overly formal or salesy language can be off-putting.
• Keep It Mobile-Friendly: With most people checking emails on their phones, make sure your subject lines are optimized for mobile. Shorter is usually better.
• Be Honest: Don’t try to trick people into opening your email with a misleading subject line. If the content doesn’t match the subject, you’ll lose trust.
• Don’t Forget the Preheader: That little snippet that shows up under your subject line in the inbox? Use it! It’s extra real estate to hook readers into opening.
