The subject line of your email is the most important part. That’s because they determine whether someone opens your email, doesn’t read it, or sends it to spam. This is why it is critical to choose the best subject lines for cold emails. If you spend all of your time and energy crafting the right email content but don’t give your cold email subject line much thought, you’ve found the reason why your campaigns aren’t working.

A study by SuperOffice found that 33% of people who get emails open them because of the subject line. Optimizing it is one of the best ways to get more people to open it, which will lead to more responses and sales.

The subject line of your sales email affects how many people open it, click on it, and complete the call to action. You can’t follow up with a lead or get a comment if they don’t open the email, right?

That does sound like a lot of work for 60 characters, doesn’t it? Don’t worry; we have got you covered. In this blog, you will find over 100 email subject lines that draw attention and increase the chance of getting opened.

But before we go there, let’s help you with something more basic. What makes a good subject line? Once you know that, it will be easy to write them, and your open rates will go through the roof. So, let’s start there.

What Makes a Great Subject Line for Cold Emails?

When you send a cold email, the subject line is like a window into your email. No matter how well you write your cold email, no one will join if they aren’t interesting enough. So, how can you make that happen?

Here are some simple steps you should follow to achieve that goal:

• Keep it brief
• The best subject lines for cold emails should be 30 to 50 letters long. A MailChimp study found that emails with 50 characters or less have 75% higher click-through rates and 12% higher open rates than other emails.
• Keep It relevant
• Put yourself in the shoes of your client and try to figure out what drives them and what their goals are. Making the subject lines of your cold emails interesting is the next step. You need to give your customers something of value and answer the age-old question, “What’s in it for them?” Why should they read your email? Be clear and give them a reason.
• Test your subject lines
• Write three to five subject lines for each email, then pick the best one or use A/B testing to find the winners. Keep in mind that since iOS 15 came out, picking winners based on open rate might not be the best way to go.
• Avoid spam traps
• Avoid spam trigger words like make extra cash, get out of debt, click here, 100% free, will not believe your eyes, and other clickbait phrases. Also, don’t use weird spacing, too many punctuation marks or capital letters, or special fonts.
• Personalize when possible
• Not just their name, but also information about where they live, what they bought, what they’re interested in, and more. You can do this with email automation and dynamic passwords.
• Use preheader text
• This is like the description of your subject line; here you can add more information to make the email more interesting. Put the “view in browser” links and other useless stuff at the bottom of the email to make the most of the sample field.
• Now that you have an idea of what the best subject lines for cold email should look like, let’s find out some really interesting examples that boost the chance of getting opened and actually read.
