Best +200 Email Subject Lines for Everyday Work

Every email begins with a subject line. Whether you work in marketing, IT, or any other field, for sure, you've had to send numerous emails yourself.

Writing a catchy subject line can be frustrating and cause sleepless nights. That's why we have prepared this guide to help you.

You’ll learn effective strategies for writing email subjects that won't go unnoticed. Besides, you’ll gain a clear understanding of what makes a good subject line and what to avoid.

Let's get started.

Key Takeaways

Here are the key takeaways if you don't have time to read the entire article:

An email subject should state or suggest what is inside the email.
A good marketing email subject should be attention-grabbing without being clickbait.
Subject lines should be brief, clear, and relevant to the recipient's interests or needs.
Conduct A/B testing on your email subject lines to determine which one is the top performer.
Avoid spam words that can trigger spam filters or simply turn off the reader.

Why are Email Subject Lines Important?

A well-written subject line does more than just summarize the email content. It is extremely important in determining whether your email will be opened and read (or just ignored).

The sad truth is that your email has to compete with many others for attention in a crowded inbox. An engaging subject line increases the chances of your email being noticed and read. It can also set the tone for the message and help the recipient prioritize its importance.

Having a well-crafted subject line is also crucial for the success of an email campaign. It directly affects open rates and the return on investment for marketing purposes(keep in mind that the average expected ROI is $40 for every dollar you spend on email marketing.)

How to Write Great Subject Lines?

When you're writing an email, you should think about your message and who you're sending it to. A catchy subject line will help your message stand out and get noticed.

Whether you're writing a newsletter, running an email campaign, or just trying to reach someone, it's important to keep a few things in mind:

Be Concise: For effective email communication, keep your subject lines brief and powerful. Stick to 50-60 characters to ensure full visibility on mobile devices where most people read emails.
Maintain Clarity: Your email subject line should be specific and avoid vagueness or ambiguity. A clear subject line helps in categorizing and searching and ensures trust.
Make it Relevant: Customize your email subject line based on your audience's interests, needs, or actions. This is especially crucial for marketing emails to improve open rates. For workplace emails, ensure relevance by mentioning current projects, deadlines, or recent meetings.
Use a Call to Action: Consider including a call to action (CTA) in your email subject line if it is appropriate. This tactic is effective in marketing and sales emails, as it urges the recipient to take a specific action, such as “Register Now,” “Claim Your Offer,” or “Read Our Latest Report.”
Avoid Spammy Words: Certain words and phrases can trigger spam filters or simply turn off the reader. Avoid using overly promotional phrases, such as "100% free" or "0 risk". Also, be mindful of CAPITALIZING all letters or using excessive exclamation points, as these can come across as spammy.
Test and Optimize: If you want to improve your subject lines, try doing A/B testing. Send different variations of your subject line to different groups of people and see which one performs better. Then, use this feedback to fine-tune your approach and improve your email campaign.

Now that we've covered the essential practices for writing an email let's move on to the list of great subject lines you can try.
