Why Are Email Subject Lines So Important?

Let’s understand why email subject lines are so important,

First impressions

The subject line is the first thing recipients see when they receive an email. It sets the tone and creates an initial impression, determining whether the email is worth opening or not. A well-written subject line can get the recipient curious, while a poorly constructed one can lead to the email being ignored or deleted.

Open rates

Cold emails, by definition, are sent to people who haven’t previously engaged with the sender. Thus, the subject line determines the email’s open rate. An interesting and relevant subject line can increase the recipient’s likelihood of opening the email, while a generic one may result in low open rates. Therefore, you need to work towards boosting email open rates.  

Deliverability

Email providers use algorithms to filter out spam, and one of the factors they consider is the subject line. That’s why using all caps, excessive punctuation, or spammy keywords can cause your email to be flagged as spam and end up in the recipient’s junk folder. Writing a concise, professional, and relevant subject line can improve your email’s deliverability.

Relevance and personalization

A good cold email subject line should be relevant to the recipient and their needs or interests. Personalization can help demonstrate that you’ve researched and genuinely care about the recipient’s concerns or pain points. This can increase the likelihood of engagement and improve the overall effectiveness of your cold email campaign.

So, now you know why subject lines are essential. Hope the above is enough to convince you to work on improving them. 

What Types Of Email Subject Lines Get Opened?

Certain subject lines in cold outreach have higher chances of being opened than others. Such subject lines are include the following:

1. Personalized: Include the recipient’s name or other personal information to make the email feel more relevant and tailored to them.
2. Urgent: Create a sense of urgency by using phrases like “last chance,” “limited time,” or “ending soon” to prompt the recipient to open and act quickly.
3. Curiosity-creating: Write subject lines that get the reader curious by asking a question, making a bold statement, or using a striking phrase.
4. Benefit-focused: Clearly state the value or benefit the recipient will get from opening the email, such as “Save 50% on your next purchase” or “Improve your productivity with these tips.”
5. Short and sweet: Keep your subject lines concise and to the point, ideally under 50 characters, to ensure they’re easily readable on all devices and platforms.
6. Emotionally appealing: Tap into the recipient’s emotions using positive or negative sentiments, like “Achieve your dreams with this guide” or “Avoid these common mistakes.”
7. Creating FOMO (Fear of Missing Out): Use exclusivity or scarcity to encourage recipients to open the email, with phrases like “exclusive offer” or “limited spots available.”
8. Providing Social proof: Leverage testimonials, reviews, or endorsements to demonstrate credibility and trustworthiness, such as “Join 10,000 others who’ve benefited from our program.”

What Types Of Email Subject Lines Are Prohibited By The CAN-SPAM Act?

The CAN-SPAM Act is a U.S. law enacted in 2003 that sets guidelines for commercial emails. While the CAN-SPAM Act does not specifically list prohibited email subject lines, it does outline several requirements that email senders must follow.

To comply with the law, you must use subject lines that truly reflect what’s in the message. That obviously means misleading subject lines are not allowed. The subject line must indicate the nature of the email content.

Here are a few types of subject lines that are not acceptable,

• Subject lines imply the recipient has won a prize when they have not. 
• Subject lines that suggest a fake urgent matter, such as “Your account has been compromised!” when it has not. 
• Subject lines falsely claim a pre-existing relationship, like “Re: Our conversation yesterday” when no such conversation took place.
• Subject lines that use clickbait tactics to entice recipients to open the email but do not accurately represent the content of the email.

What Are The Best ChatGPT Email Subject Line Generation Tips?

Here are some tips to utilize ChatGPT for generating email subject lines as a sales rep:

1. Be specific with your prompts

When asking ChatGPT for suggestions, provide the context and be specific about your target audience, your product or service, and the goal of the email. This will help the AI generate more relevant and targeted subject lines.

2. Test multiple prompts

 Try different approaches and angles when providing input to ChatGPT. This will yield a variety of subject lines, giving you more options to choose from.

3. Focus on personalization

Use the recipient’s name or other personal details in your prompt to encourage ChatGPT to generate subject lines that create a sense of connection with the recipient.

4. Keep it short and sweet

Encourage ChatGPT to generate crisp subject lines by mentioning a desired length in your prompt. Short subject lines are more likely to be read and can help avoid being cut off in email clients.

5. Generate multiple suggestions

Ask ChatGPT to provide multiple subject line suggestions in one response. This will give you more options and inspire you to create even better subject lines.

6. Opt for curiosity and urgency

Request subject lines from ChatGPT that evoke curiosity or create a sense of urgency, as these tend to have higher open rates.

7. Perform A/B testing

Use ChatGPT to generate different subject lines for the same email and conduct A/B testing to see which one performs better. This will certainly help you optimize your subject lines for higher open rates.

8. Iterate and refine

Don’t be afraid to edit and refine the suggestions provided by ChatGPT. The AI can be a great starting point, but user input can help ensure the subject lines are well-written and contextually right.

Remember that while ChatGPT is a powerful tool, it’s important to use your own sense of judgment and expertise to ensure the subject lines you choose are relevant, engaging, and in line with your brand’s voice.
