If you're like me, you leave email subject lines for last. In short: They're difficult to write. You need to keep them short and sweet but still make sure that they scream "read me!"  How do you do that in so few words? Well, it depends on the type of email that you're sending. Here are some tips and examples.

21 tips for writing a strong subject line

Whether writing a subject line for a marketing campaign or for your everyday communication, there are some key tips to keep in mind. Regardless of the contents of the email, your subject line should have one goal in mind: get the recipient to open it and, ideally, respond.  Your subject line is like your first impression. It needs to wow the recipient enough for them to care about what else you have to say. Here's how you can do just that.

1. Keep it short.

Your subject line should just be a quick few words that are easy to digest when the recipient is scrolling through their email. Too long, and it could easily overwhelm them enough to skip over the email entirely.

2. Keep it relevant.

Make sure that your subject line is either clear about what your email entails or a witty insinuation of what's inside. Whether you go with a direct "Followup on Today's Meeting" or some clever, metaphorical line, your subject line needs to make sense. 

3. Be descriptive.

Don't just write a subject line for the sake of writing a subject line. If you're pushing a campaign or sale, for example, include some enticing specifics about it.

4. Personalize it.

Whether you're a brand reaching out for a birthday special or you're a job candidate introducing yourself via a referral, personalize the subject line. Now is the time to drop names.

5. Keep punctuation to a minimum.

Mailchimp research shows that too much punctuation in subject lines make emails look spammy.

6. Don't use more than one emoji.

Mailchimp research also says to limit your emojis to one max. And test the one you do choose because it may appear differently on different operating systems.

7. A/B test your subject lines.

Test out different subject lines to see what works best for you. Which kinds of emails are your recipients opening more? Go with those kinds of subject lines.

8. Avoid buzzwords.

Buzzwords can raise red flags about your subject line that scream spam.

9. Steer clear of jargon.

Don't use industry-specific jargon that your recipient(s) may not understand. Instead, stick to easy-to-digest language that won't fall on deaf ears.

10. Ask questions.

Ever hear of the saying, curiosity killed the cat? Questions can pique curiosity and prompt your recipients to open the email—if only to find out the answer. Either way, now you have their attention.

11. Make bold statements.

Make statements that incite curiosity and emotion. Just make sure that you're not spreading fake news.

12. Use an ellipsis...

Ending your subject line with a dot, dot, dot is like leaving those scanning their inboxes with a cliffhanger.

13. Include a deadline.

Adding a deadline to your email adds a sense of urgency, which may entice the one on the receiving end to open it sooner rather than later.

14. Try teasers.

If you're trying to sell a product or service, consider teasing it in the subject line so that the recipient is curious enough to find out what it really has to offer them.

15. Speak with conviction.

Psychology would have it that when you speak with conviction, assuming the sell (whether you're actually pitching a product or selling yourself), is convincing. 

16. Offer something valuable.

Understand the current state of affairs — whether it's related to what's going on in the world or at the company — and leverage that. Offer a valuable idea or solution, and then expound on it in the body of your email.

17. Make them laugh.

People like to laugh so tell a joke or make a clever play on words. If it's funny enough, whatever you have to say, the recipient may be inclined to read more.

18. Say something unexpected.

Shock always catches eyes. Get their attention by using a subject line no one would anticipate popping up in their inbox.

19. Be frank.

If you're writing an email to raise a point, don't beat around the bush. After all, you don't want to clutter any part of your email with fluff words that could distract from your point.

20. Make an announcement.

If you have something important to share, chances are that it'll matter to the people who matter. You shouldn't reveal the news in the subject line, but you can certainly excite people to click open and find out.

21. Be casual.

If you're emailing your coworkers about everyday doings, you don't need to come up with a fancy subject line that'll feel forced. Keep it casual. People like working with people, not robots.
