Email marketing has always been the best marketing tactic for all online businesses. Professionals rely heavily on email marketing to generate leads, increase conversions, and grow their businesses always.
And nowadays, the inbox of everyone is flooded with tons of emails. So, it is challenging for you to get higher open rates.
Hence, you must use an important email subject line that stands out in the inbox. Since the subject line is the first thing your recipient will see, it will act as the main deciding factor in whether or not people will open your email.
According to Super Office, 33% of recipients decide whether to open an email or not based on the subject line alone.
Whether you’re a small business owner, digital marketer, or freelancer, a good subject line is essential for email marketing campaigns.
So let’s begin.
What Is an Email Subject Line?
An email subject line is a short, descriptive text that appears in your inbox before you open an email. Its primary function is to summarize the email’s content and entice the recipient to open it.
In email marketing, the subject line is crucial as it greatly influences the open rates. A compelling subject line can capture attention, create curiosity, convey urgency, or highlight the value of the email’s content.
Crafting an effective subject line involves being clear, concise, and relevant to readers’ interests or needs. It should give a reason for the recipient to open the email, making it an essential element in successful email communication and marketing campaigns.
Email Subject Lines Best Practices
When writing the best email subject lines, you need to consider a lot of factors that will help to increase the chances of your leads opening your emails.
Following are a few best practices that most businesses follow:
1. Keep It Short & Concise – 5-7 Words Or Fewer
It is advised to include at most 5 to 7 words in your subject line. While this is not mandatory, it helps the reader to view it at a single glance in his/her email platforms.
2. Personalize Where Possible
Personalizing the subject line can help to gain the trust of the prospect in your email. To do so, you can include the prospect’s name or other relevant personal information about the prospect in the subject line. Or, simply use the second-person point of view (by using “you”).
3. Give a Clear Message
Your email subject should give a hint of what the reader may expect in the email body. Do not simply write a generic subject line that doesn’t pique the interest of your prospects.
4. Avoid Using All Caps
Using all caps can come across as aggressive and spammy. Instead, use proper capitalization.
5. Reduce The Use of Spammy Words
There are certain words that most email clients consider as spammy words. These may include words such as “free,” “limited time offer,” “act now,” etc.
However, this doesn’t mean you cannot use these words at all. The context of the subject line and the email body determines if a word is considered spammy.
6. Consider Using Emojis
Since a prospect will see a lot of emails in the inbox, one good way to stand out is by using clever emojis. An emoji will act as a single out-of-the-crowd object that will draw the attention of the prospect.
7. Avoid Exggerated Subject Lines
When running or planning email campaigns, it’s natural for you to want to create excitement. But this should not lead to exaggerating what you have to offer in your email.
For example, last week, I received a spam marketing email with the following subject line: “Best advice you will ever get…”
Now, this subject line has two red flags.
– First, this doesn’t tell me what the email is about.
– Second, calling what’s in there the “best” rather makes me more skeptical about it than excited.
So, in the upcoming section, I have discussed 20 versatile types of email subject lines with around 200+ examples that you can take ideas from to implement in your marketing game right away.

Bonus Tips
While writing the best email subject lines, many things may get confusing at times. But here are a few tips to help you out.
i. Use ChatGPT to Generate The Best Email Subject Lines For You
If you are unsure which subject line is appropriate for you, get help from AI tools such as ChatGPT or AI integration within your Email Marketing tool.
As long as you give proper instructions, the tool will be able to give you high-quality and best email subject lines.
Here’s an example of proper instruction: “I want to send an email to my current Pro users about this new AI integration feature to generate email copies. But I want the subject line to be a cliffhanger.
Generate 5 email subject lines for this which should be less than 80 characters each.
- ”This generated the following for me:
- “Revolutionize email writing with AI 🚀”
- “Unleash the power of AI for email 🤖”
- “New feature alert: AI copy generator 🆕”
- “Say goodbye to writer’s block 🖋️”
- “Email marketing just got easier 📈”
**You can use Mail Mint to generate catchy email subject lines with ChatGPT.**
ii. Run A/B Testing
Run A/B Split Testing for subject lines when running long-term or repetitive email campaigns. This will help you identify the best email subject lines that will deliver the highest open rates.
For example, based on the subject lines above, let’s say you selected the 1st two. Then you can do a 50/50 split test for the first 100 leads.
Based on the results, you will be able to determine which one delivered higher open rates and make that the main subject line for the rest of your leads (or you may do a split test with another subject line). Most marketing campaign goals get more successful after running A/B tests.
iii. Remove Invalid Leads
For cold emails, first, use a tool to remove all the invalid leads. No matter how you collect your leads, if you are willing to run cold email campaigns, then it is important to reduce the email sending costs as much as possible.
The best way to do this is to use a reliable email verifying tool such as Clearout before running your email campaigns.
iv. Set Up Email Automation Flows
Set up email automation flows for your leads based on their activity in the emails to maximize your email campaign results.
For example, whoever doesn’t open your email within 48 hours, set up an automated email to be sent again, but this time, make it sound like a reminder with the subject line, “Hi [Name], did you get a chance to check out my last email?” This will make the recipient curious and may consider reading your email.
Conclusion
Effective subject lines are critical in email marketing as they are the first thing a recipient sees and can determine whether or not they will open the email.
A strong subject line can grab attention, create curiosity, and encourage action. In contrast, a weak subject line can result in the email being deleted or marked as spam.
To maximize the impact of email subject lines, it’s important to experiment with different types of subject lines and analyze their performance.
You can easily utilize your subject lines with Mail Mint without any extra effort. This tool will save you time and help you to get targeted customers easily.
