40 powerful email subject lines for sales

The importance of a subject line

What is a subject line in emails?

If you look at a typical email in your inbox, you’ll see a single line of text near the name of the sender. Here it is - a subject line! This tiny text plays a significant role: looking at it, you decide whether to open the letter or just ignore it.

Why does it matter?

Just one thought about the huge number of emails we send and receive every day is enough to conclude that it’s impossible to read or at least look through each of them. But how do we choose which to open and which not to? 

When your clients receive a message from you, its subject line is the first thing they notice. Since email boxes are full of various letters from different companies, clear and catchy subject lines can highlight yours. Powerful words can have a persuasive effect on the recipient. After all, your email campaign is worth nothing, if clients don’t open the emails you send.

Working a bit harder and spending more time on a subject line can bring many benefits:

  • Boost your email open rate
  • Lower chances for an email to be sent to the spam folder
  • Entice new customers

Top techniques to write powerful subject lines

1. Use personalized approach

People like being called by their first name. Adding it in an email subject was once considered enough to be called “personalization”, but today it’s better to make the impression as if you’ve known your customers for years, mentioning other personal information, like the purchase history, location, or a pet name. Also, try wordplay with a client’s name. Doing so will not only draw their attention but also win you some points for creativity. If you don’t consider yourself a creative person, simply use “you” or “your” to address a recipient directly. 

2. Start with a strong call to action

With tons of incoming emails, only a few people are always ready to read a letter from beginning to end to find out what it can offer. So why not ease this task and place a call to action right at the top? Actionable email subject lines, for example, “Start a new you today” or “Be ready for your next meeting” will make your recipient take concrete steps and accept your request. This will sound professional and at the same time will help you get straight to the point. 

3. Share something valuable

Every subscriber needs something right now, and you should be attentive to their demands. Sharing something of high value with the audience is a major factor of a successful marketing strategy. Try putting yourself in your client’s shoes and thinking over some possible options to offer. For some, it may be traveling tips, for others - a monthly plan for losing weight. Popular services, like RingCentral or Whoosh, regularly send a newsletter with useful articles about online meetings, putting great attention to its benefits for their customers. That’s why highlighting the value of a message for clients will increase its chances to be opened.

4. Carefully choose words to avoid spam filters

The worst thing that could happen with your email is not reaching the recipient’s inbox. And being put to spam is among the major reasons for that. So always remember to write a subject line carefully avoiding spam words. Email clients don’t like aggressively salesy titles and usually mark letters with them as spam. Instead of excessively focusing on sales and marketing, try offering your experience and professional skills, sharing information that your target audience will definitely find useful. 

What else to avoid:

  • Caps and multiple exclamation points
  • Highly promotional language (“free”, “try/buy now”, “only today”, etc.)
  • Statements that are too good to be true (“while you sleep”, “additional income”, “billion dollars”, etc.)
  • Shady words and phrases (“hidden”, “passwords”, “this isn’t spam”)

5. Use emojis but don’t replace words with them

You may think that emojis are everywhere: you see them on social media, send on messengers, your posts have at least one. However, emails are not so overpopulated by smiling faces and cute animal muzzles. The key reasons for that are their changing appearance on various devices and different meanings in various regions of the world. Moreover, if you replace the whole word with an emoji, this may puzzle your readers and cause misunderstandings. 

But there’s no need to worry! You are free to use these cheerful signs, but do it wisely:

  • Don’t use signs, which may be misinterpreted by someone from another country.
  • Don’t add more than one emoji at a time.
  • Use only those that correspond to the topic and tone of your email.
  • Don’t add them to formal correspondence.

6. Use numbers if possible

Sometimes it’s more effective to replace vague statements with numbers, statistics, and interesting facts. Figures will make a title look clear and straightforward. They may be surprising, shocking, or enticing, all depending on the message you want to convey. People love numbers and statistics and will definitely be interested in opening a letter, which starts with “Why don’t you use these 8 tips?” 

7. Keep it short

We live in a busy world, where no one likes to read long lines of boring text. So when thinking over a suitable subject line, remember about the following trick: use no more than eight words. Doing so won’t let your title be cut off in the middle of a sentence. Moreover, you should remember about desktop and mobile symbol limits: 60 and 30, respectively. That’s why we recommend creating short and meaningful subject lines to avoid confusion and misunderstandings. Save all the details to mention them later in the main body of an email.

8. Ask a question

Questions are an effective way to draw your subscribers’ attention and keep your open rates high. Try asking open-ended questions to inspire readers to read a letter and look for the answer to your question. But don’t make them sound too straightforward, create intriguing and encouraging questions to entice readers, not let them get bored.

9. Make it look like a teaser

What do you like more - a movie trailer or commercials? So as your audience. Try making a subject line sound alluring and promising to let them wonder what’s next and then open your letter. Yes, a great call to action can be a suitable option, but sometimes a preview may do a better job. A creative hook at the beginning will draw the attention of your readers and spark interest in their minds. 

10. Double-check

To err is human. It’s true for everyone, especially for those who send dozens of emails every day, in a hurry, from a smartphone. When we write and read texts all day long, it’s easy to overlook some grammar or spelling mistakes. They may not be critical but can give off a negative impression and cause you to look less professional. 

But there are some effective ways to always be on top:

  • Use online grammar and spelling checkers
  • Don’t send emails in a hurry or when tired or angry (if they can wait)
  • Take a 5-minute break and then reread a letter
