Top 10 sales email subject lines to increase open rates

Reading Time: 5 Minutes Practical Marketer

You invest time drafting a perfect sales email pitch, inserting the perfect links and crafting the perfect CTA (call-to-action) for your emails. Is your time well spent?

All this is a waste if nobody even bothers to open your email. This is where the importance of a subject line becomes the topic of discussion. Email marketing is still among one of the best method of communication with prospects, leads and customers. In the era of the crowded email inbox, before your prospects, leads or customers reads your email … it has to be opened first. That’s why the subject line of a sales email plays a vital role. The more people that open your emails, the increased probability for sales.

Hundreds of billions of sales emails are sent every day to grab the attention of the customer. How many unread emails are there in your inbox? 200? 500? Probably 1,000 if you have subscribed to countless mailing lists. People today get many emails daily and most of them go unopened. People are flooded with more information than ever before and have less time to soak it all in. Most of the emails are simply ignored … unless they have a rocking subject line. According to a study on email statistics, 35% of recipients open emails based on the subject lines alone and 69% of the recipients report an email as SPAM based on the subject line of the email alone. There isn’t a silver-bullet subject line for a given subject, because what works for one business might not work effectively for another.

Just think about this: will you open an email that has a subject line “Open Me” or “Hi” or “URGENT” or “Register to win FREE iPhone 6S+” or something similar? All such emails directly land in your SPAM folder. A bad subject line will get 5x less customers that open and read your emails.

The best sales email subject lines should be creative, igniting the interest in the customers. They should have a curiosity seeking subject that is relevant to them, all while also being informative.

Looking for some interesting and provoking subject lines for your sales emails that scream out “Open Me Now?” Then here are best sales email subject lines that will boost the open rates of your emails:

“Need My Help?” or “Hoping to Help”

The best sales people today are the ones who can help their customers solve problems. If your email lands in the inbox with an open-ended subject line like “Tell Me What You Have Been Struggling With” or “Tell Me Everything That You Have Tried and How Can I Help You” or something like “Hoping to Help” there is an increased chance for your emails being opened. Prospects get an idea on your willingness to be of service to the customers.

“[Name of the Prospect], do you have 15 minutes for a conversation?”

These kind of subject lines distinguish your emails from other marketers, because you’re asking a question directly in the subject line which addresses the person with his or her name. Personalized subject lines with a question in the subject help increase open rates.

“We found you through [Name of the Referral]” or “[Name of the Referral] suggested that we connect”

If someone referred you to a prospect, make sure to use their name in the subject rather than saving it for the body of the email. Using the name of the referral in subject line grabs a prospect’s attention right away and also gives automatic credibility to the sender for leveraging an existing connection of the prospect.

A Subject Line With A Reply “Re”

Many marketers use a “Re:” or “FW” in their email subject lines with an eye towards increasing their open and conversion rates. This is a clever tactic, as it exhibits a personal relationship with the prospect that you know them. However, once a prospect open the email and gets to know that they have been tricked and have not had any prior conversations with you this kind of an email subject line will not impress them.

If you have actually spoken with them before and this is a factual reply then you can try removing the subject line as a whole and just including “Re” to increase the response rate of your sales emails.

Email Subject Lines That Convey An Idea The Prospect Cares About

If you are a blogger, an email with a subject “Idea for increasing unique visitors to your [blog name]” may intrigue you enough to click through the email and read it. Nobody wants to miss out on a free idea and the probability that prospects will open an email is greatly increased.

Listicle Subject Line With Tips Or Ideas

Listicle subject lines in sales emails are an effective and simple way to attract the attention of prospects.  If you are an email marketer, a subject line with “10 Best Email Subject Lines to Increase Your Open Rates by 80%” will attract you more than a subject like “Email Subject Lines To Increase Open Rates.” Using numbers in the subject line makes a prospects aware of what they are going to read.

Personalized Email Subject Lines with a Question: “Hi [Name of the Prospect], [Question the prospect is looking to solve]?”

If James is a content writer, then an email with a subject line something like “Hi James, Do you know how to write compelling content that boosts traffic?” will surely motivate James to open the email as it addresses his problem. Subject lines with a question are a great way to compel people to open your emails, as prospects are promised that the email content is intended to guide them and help achieve a goal.

“Don’t Open This Email”

Human Psychology works just the opposite way. If someone refrains you from doing something, you always are keener on doing it. This subject line is the most simple and effective means to create curiosity among the prospects to open your emails.

Email Subject Lines That Benefit the Prospect= “A [Benefit] for [Prospects_CompanyName]”

If a company, “ABC Inc.,” has recently launched a blog and is looking to increase its subscriber base, then a sales email subject line like “Get your first 2000 subscribers to the ABC Inc. Blog” will invoke the self-interest in opening the email to find out what’s in store to increase the number of subscribers for the blog and help it grow. That level of personalization in the subject line is likely to catch the eyes of the prospect.

Email Without A Subject Line / A Blank Subject Line Email
