  • Why are email subject lines so important in May?
  • What are the most important things to do with each email?
  • What are good email subject lines your business can use this May?

The email marketing forces within this post are strong, and your business’s email plan is bound to be too!

 

Why May email subject lines are important

Email marketing should be a part of your marketing plan year-round. However, it can be difficult for businesses to maintain revenue-growing email subject line ideas during the busy spring months. These data points prove that paying attention to your email marketing strategy is worth the extra effort:

  • Your target audience is bound to be on email as the number of global email users is projected to grow to 48 billion users by 2024.
  • Small businesses claim that email marketing is the marketing channel that brings them the highest return on investment.
  • 64% of small businesses say they use email marketing to reach their ideal customers.
  • 47% of email recipients decide to open an email based on the subject line alone.

At the minimum, these statistics prove that your May email subject lines can help you maintain your business’s progress throughout the month. If you still feel like email marketing could be a stretch this May, don’t hesitate to reach out to a marketing partner instead to help empower your strategy.

5 May email subject line tips

Email marketing is something you won’t want to miss out on this May, but how can you make sure each email truly packs a punch? Follow these email subject line tips to make the most out of your May email marketing:

1. Remember the most important part of every email

The most important thing you should do with every email starts with your email subject line: conveying a clear and specific message to your recipient. Be sure your email subject lines make a point and explain what action you’re hoping viewers complete.

For example, if you want to drive traffic to your website, you might use your subject line to tell your audience about what they’ll want to click next.

2. Be concise

Using compelling power words to shine through in your email subject lines means you can say more with less. In fact, 82% of businesses keep their subject lines under 60 characters. A concise email subject line is just as important as a goal-oriented email subject line—especially since over 40% of consumers now open emails on mobile devices. Make your business stand out on limited screen space by keeping to our email subject line character count chart below.

3. Use emojis, hashtags, and more…

While you’re using a clear and concise call to action in your May email subject lines, you also don’t want to forget to have some fun with your email copywriting. For example, did you know 33% of people will open an email just because they think it has a catchy subject line? Make your subject line pop by using creative elements like emojis or hashtags to see higher open rates.

4. …But avoid these words in your email subject lines

Despite wanting to spice up your emails using the tactics mentioned above, there are some words you should not use in an email subject line.

Let’s use an example. Say you’re running a giveaway or contest and want to include the word “free” in the subject line. That will lead to your email being 10% more likely to be opened. However, in contrast, using terms like “guarantee,” “hidden,” or “best price” could seem less genuine in this case and lead your audience to think your email offer is spam.

Choose your promotional words carefully. Some, like “free,” can increase open rates, while others, like the ones in our handy image below, can do the opposite. Since 69% of email recipients report emails as spam solely based on the email subject line, you won’t want to forget this tip.

5. Maintain personalization in your May email subject lines

If you’re short on email subject line ideas for May, a personalized marketing experience is always a great default. You’ll want to include your recipient’s first name in the subject line to foster a higher click-through rate.

You could also kick your email targeting up a notch by segmenting your recipient list. This can help you stand out from competitors, as businesses that have segmented their audiences for email campaigns saw a 760% increase in revenue. This checks out since customers across different stages of the buyer’s journey will be looking for varying email offers.
