Looking to improve your email response rates through better email subject lines? Here are the 21 Best Email Subject Lines for sales that will definitely get you a response for your sales. Email marketing is an effective marketing channel if you are trying to include it in your multi-channel marketing stack to promote your brand, products, or services. But landing in your prospect’s inbox and having an effective email subject line for sales that gets responses is the most difficult part of it.

People make a tone of assumptions about sending the right content in the email, using subject lines, running A/B tests, and so on. Let’s try to find out what kind of subject lines work best and give you better results for your cold outreach campaigns.

What Makes a Good Email Subject Line?

We must first understand what makes a good subject line before we discuss the best email subject lines for sales. The most effective subject lines for sales emails are:


For the majority of email providers, the subject line length is 60 characters. To ensure that your subject line will be displayed completely on desktop and mobile devices, you should aim for between 40 and 50 characters (4 to 7 words).

Additionally, it will be easier to read and understand a brief subject line.


The prospect will understand that there is a real person behind the email and that they are not the target of a mass spam campaign if the subject line is personalized.

They’ll be grateful that you invested the time and effort to find out who they are and what they truly require rather than merely sending out messages to thousands of people who are similar to them randomly.

They’ll be more inclined to open and respond to your email as a result.


Prospects are more likely to open your email right away rather than save it for later if your subject line creates a sense of urgency.

This strategy can be particularly useful for follow-up emails sent after the prospect hasn’t responded.

Why Is It So Important to Get Email Subject Lines Right?

When making a cold call, your topic line serves as your opening line. To put it simply, they calculate your email open rate: 47% of recipients base their decision to open an email solely on the subject line.

You can’t sell your prospects on the contents of your emails if they don’t open them.

But if your subject lines strike a chord with readers, you’ll get a foot in the door and an opportunity to persuade them to buy from you. The problem is that writing effective subject lines is notoriously difficult.

The average professional receives about 100 emails every day. From urgent customer requests and team notices to newsletter updates and password resets, everything is flooding their inbox.

Your email is unlikely to be opened unless it is a priority because there is so much to sort through.

Because of this, it might be challenging to grab your prospect’s attention with a subject line that piques their interest enough to continue reading. It should come as no surprise that the average email open rate across all industries is only 21%.

Before You Get Started

Consider the following first if you want to make your subject line truly effective:

To whom are you marketing? Consider who you are attempting to market to, what matters to them, and what drives them. Verify the potential customer’s website or LinkedIn page (if they have one). When creating your subject line, consider using this information.

What kind of value do you provide? What problems does your product or service solve, in other words? Instead of emphasizing the product or service itself, your subject line should highlight the value the prospect will receive from it.

Do you share a connection with the potential client? See whether you and the potential client have any ties in common. Perhaps you are friends on Facebook or LinkedIn or belong to the same group. If you discover a link between two prospects, include it in the subject line to attract their attention and boost the likelihood that they’ll read your email.
