What Constitutes an Email Subject Line? (Explanation)

The email subject line or heading stands as the initial text encountered by the recipient upon receiving your email. It represents the text that you typically compose to seize the attention of the person receiving your email.

The significance of email subject lines cannot be overstated; they serve as the inaugural impression. While you might compose an impeccably crafted email, an ineffective subject line will deter readership.

Crafting a compelling email subject line involves a fair amount of psychological consideration. Let’s delve into the essential do’s and don’ts.

Email Subject Line Best Practices and Recommendations

Ensure adherence to these guidelines!

Be Clear and Concise: Craft a subject line that is unambiguous, concise, and pertinent.
Integrate Emojis: Incorporate emojis to add a personal touch. However, excessive use may relegate your email to the spam folder.
Personalize: Enhance the open rate by addressing the recipient using their first name 2.
Utilize Emotion-Driven Words: Employ words that evoke emotions. Emotional resonance encourages clicks.
Harness Curiosity: Drop hints that pique interest without revealing everything. Curiosity is a compelling motivator.
Test and Optimize: Conduct A/B testing with different subject lines to identify the most effective approach for your audience.
Choose the Right Time: Studies indicate that 11:00 am EST is optimal for email opens 3, and Tuesday emerges as the most favorable day for sending emails.
Highlight Timing: Subject lines featuring dates or conveying a sense of urgency generally yield better results. According to a Return Path 4 study analyzing 9 million subject lines, specific urgent phrases and words outperform others:

Top keywords in urgent subject lines	Average read rate for subject lines containing this keyword
Still time	33.73%
Limited time	14.93%
Expiring	16.60%
Last chance	16.71%
Now	15.75%
Expire	16.69%
Hurry	19.01%
Extended	9.20%
Running out	9.92%

But don’t abuse their fear of missing out, or you’ll come off as spammy and stressful.

Additionally, exercise caution to avoid these don’ts:

Avoid Misleading Content: Crafting a clickbait subject that doesn’t align with the email content can erode trust.
Steer Clear of Spammy Language: Refrain from using clichéd sales language, excessive punctuation, or all caps, as they may trigger spam filters. An email with a subject like HURRY!!! Your EXCLUSIVE Deal Awaits! Open NOW for FREE MONEY! may deter recipients.
Keep Subject Lines Concise: Long subject lines are prone to being truncated, especially on mobile devices.
Avoid Soliciting: Mailchimp 2 analysis of donation-related words revealed that terms like helping, fundraising, charity, and donate negatively impact open rates. Consider postponing any requests for later stages.
Eliminate Typos: Subject lines containing typos convey an image of unprofessionalism and lack of preparation.

Now, let’s get into some sample subject lines that you can use for your emails!

Compelling Email Subject Lines

Presented below are subject lines that prove highly effective across various situations—just ensure their authenticity! Refrain from using a subject line if you lack a significant announcement.

“I have an important announcement. Mailchimp 2 found that announcement (and similar words) caused a higher open rate. People want to be in the know!”
“Question for you This email subject line invites the receiver to open your email and help you. It also works because of the Benjamin Franklin Effect—when someone does a favor for you, they end up liking you more!”

Optimal Email Subject Lines for Sales

Achieving success in sales requires a delicate equilibrium between relatability and effective selling. It is crucial to avoid any form of misdirection, a pitfall that is particularly prevalent in sales emails.

GovX employs an email subject line that suggests the availability of a “free” knife, only to reveal that it’s actually a discount. Disappointing!

A significant number of individuals categorize emails as spam solely based on the subject line. Here are excellent examples to master your sales subject line for your email campaign:
