Example: Did you know 73% of clients see improvement using this tactic?   How to Write Subject Lines That Inspire Joy You know the saying, "People won't remember what you say, but they'll remember how you made them feel?" That absolutely applies to marketing, your brand, and your email subject lines. Make people feel good and reap the rewards. Use Emojis Intelligently A well-placed emoji can be great for getting a chuckle. Example: Look your best and feel your best :) (this isn't the best example, but pretend that smiley face is a much cooler-looking emoji) Work In Humor (Carefully) Laughter is good for your health. Put people in a good mood, and they'll react more positively to your content. Example: So three marketers walk into a bar ... Give People an Opportunity to Do Good Because it feels good to do good.

Follow these steps to start writing. Identify the Topic and Purpose of Your Email What is your email newsletter about? Here are some common possibilities: Promoting a sale. Sharing your most recent content. Announcing a new product launch. Offering helpful how-to tips. Getting event registrants. If your email is part of a broader campaign, make sure your messaging is consistent, too. Know Your Audience If you're doing marketing correctly, you should know who your audience is. But, your audience may be comprised of several different market segments. So, make sure you know exactly who you're targeting. Then, craft messaging that will appeal to them. Identify Your Benefit or Value Proposition Why would someone open this email? Think about what's in it for your reader, as much as what's in it for your brand. Some examples could include: Saving money. Completing a task more easily. Doing something charitable. Narrow it down to one core benefit. Pick Your Emotional Appeal Remember Urgency, Curiosity, Excitement, and Joy? Choose one to focus on. Or, consider writing several options targeting different emotional appeals. Whichever you choose, have clear intent behind your words. Match the Message in Your Email Copy Message-match means making sure your subject line aligns with your email's content. Typically, it's a term reserved for digital advertising, ensuring ad copy aligns with a landing page. But, we can apply the same principle here. For example, if you're promoting a sale, make sure your subject line and body copy are consistent with one another. If you're promoting a piece of content, make sure your subject line's message matches what they'll find on the destination page. Write Several Options With the Email Subject Line Tester It's a good idea to try tons of different options before settling on one subject line. If you're writing for a client, you might even give them five or six to choose from. As you write different options, the tester will keep track of your scores: Plus, the tool will help you learn what works (and what doesn't).

Get More Opens By A/B Testing Email Subject Lines Nearly every email service provider lets you send A/B tests for your email subject lines. Whether you use MailChimp,  Campaign Monitor, or something similar, most provide A/B testing options when building email newsletters. This video is specific to MailChimp, but it covers a lot  of A/B testing basics that should apply to most platforms: However, what  makes a good A/B test? Let's dig into some tips. 5 Effective Tactics for Email  A/B Testing The key to a good A/B test is to choose variables that really are different from one another.  If you test two subject lines that sound too similar, you won't learn much. There needs to be a substantial difference between your two options. Consider these five different approaches when you run your next A/B test: 1. Test Two Different Value Propositions Let's say your email content is promoting a post that both: Shows readers how to save time. Shows them how to save money. These are two different value propositions. So, write two options, one focusing on each benefit. Then, see which performs best. The data will tell you which benefit your audience cares about most. That'll help you continue to write more effective subject lines in the future. The key to a good A/B test is to have options that are different from one another.2. Target  Two Different Emotions Your audience might respond better to curiosity than urgency. Or, maybe they're looking for something that will brighten their day. So, find out. Try  targeting different emotions and see what drives a better response. 3. Test Subject Line Length You might find different subject line lengths work best for you. Or, different lengths may work better for different types of messages. Consider experimenting with short  (one or two words)  versus long (seven or eight words). 4. Test Questions Versus Definitive Statements Questions can help get readers curious. However, definitive statements can express authority. Try both and see what happens. 5. Test Using Stats Statistics can drive email opens, especially when they're difficult to believe. If your email content includes an interesting stat, try incorporating one into subject line A. Then, write subject line B without a stat.

Write Your Email Content Start by writing your email copy. This will make it easier to write your subject lines. Identify Which Two Variables You'll Test Write two different subject line options. Try to emphasize something different in each one. For example, you could target two different emotions, in order to sell people on reading the same newsletter. Or, you could include an emoji or statistic in one, but not the other. Whichever you choose, the point is to know exactly what you're testing. See Which Does Best Once your email has sent, you'll see relatively quickly which outperformed the other. Use the Email A/B Subject Line Testing template we included in this post to track performance over time: Here are some specific things to monitor: Winning and Losing Subject Lines: Which options perform best? Do certain types appear to fail more frequently than others? Open Rates: How many people opened each email? CTR (Click-Through Rate): How many people click through on each subject line?

Here's how, using several popular email marketing tools: MailChimp Campaign Monitor HubSpot Pardot Constant Contact Emma Measure Your Results Use the analytics tools built into your email platform to monitor open rates. Use the template included in this post, or create your own following the graphic below. Use it to  track your winner and loser from the test, the difference in the results, and scrutinize the reason why your winner performed the best. This may require some subjective judgment. When  assessing the reason one subject line outperformed the other, keep the following in mind: If you set up clear variables in your A/B test, the reason subject lines succeed or fail should be obvious. For example, if one option includes a statistic, while the other does not, then that's a good indicator that stats resonate with your audience. Look for  patterns. The more you test, the more consistent patterns should  emerge. The days and times you send email can impact results as well. Remember that the actual content of your email may influence open rates (and in turn, your email conversion rates, too. If people aren't interested in the topic of your email, then simply following best practices might not be enough to drive opens and clicks. Great content will get attention. Following proper mechanics and technique merely maximizes great content's ability to make an impact. When it comes to email marketing, your own data beats best practices. The recipients on your email list are  different from anyone else's. What works for another business, might not work for yours. This is why it's better to know how to gather your own data than to simply follow someone else's. Don't use other's data as your guide. Use it to inspire you to get your own data.Now, Go Write Better Subject Lines! It's easy to overlook subject lines when we're writing marketing emails. They're short, so they should be easy, right?
