7 quick Memorial Day email subject line tips

Before we get into the components of an effective Memorial Day email subject line, let’s first pause and remember some key email subject line tips:

1. Remember the history

While Memorial Day has become a holiday that marks the unofficial start of summer, complete with barbeques, picnics, and family vacations, the holiday was initially created to honor members of our military who died in service. Take care not to lose sight of the holiday’s solemn origins when developing your Memorial Day marketing ideas.

It’s okay to offer deals and speak to the lighter associations the holiday has taken on, but don’t forget why it started. There are many families for whom this is a somber day of reflection and remembrance, and it’s important to keep your messaging respectful.

2. Try including numbers

Surveys consistently show that incorporating numbers into your email marketing copy can increase engagement. Instead of writing out the number, use the digit to save space and catch eyeballs. You could include a start and end date for a promotion or event, a percentage or dollar amount off for a sale, and more.

3. Use emojis (sparingly)

Emojis can also help with open rates (Campaign Monitor attributes a 56% boost in brands’ open rates boost in brands’ open rates to emojis!). Of course, emojis won’t suit every brand’s voice, and overusing emojis can make your subject line feel spammy. Only include them if they’re right for you, and do so in moderation.

4. Keep it short, sweet…

You’ll see conflicting reports about the ideal number of characters or words to include in your email subject line. Ultimately, what’s most important is writing a subject line that conveys your message.

Try using a tool to see how your email subject line will display on desktop and mobile can help you write subject lines that won’t be cut off on smaller screens. Also, be sure to save this handy guide below to have an idea of how long your Memorial Day subject Lines should be:

5. …and personal

Most email marketing tools have features that let you include things like a recipient’s first name in an email subject line. Personalization is always an attention-grabbing marketing trick since it helps you connect with your recipient in a unique way.

Aside from using your recipient’s first name, you could create targeted email campaigns for segmented email lists using varying content to speak to recipients as they’re in different stages of your sales funnel.

6. Create urgency and excitement…

This is easy to achieve when you’re emailing about a special event like, say, a Memorial Day sale. Your offer has an expiration date, and explicitly reminding your audience about it can drive clicks. “Shop our sale” and “Only 12 hours left to shop our sale” hit differently, right?

How can you create interest, excitement, and an irresistible desire to click on your email subject line? Giving readers a little taste of what they’ll see if they open the email can drive clicks.

7. …but avoid spam triggers

While it’s great to tease what’s inside your Memorial Day emails, you’ll want to avoid being dumped into your recipients’ spam folders. Keep your Memorial Day subject lines relevant to your brand and avoid any bait-and-switch tactics. The FTC’s CAN-SPAM Rule, which governs what brands can and can’t say in their email marketing, dictates that your subject line must accurately reflect what’s inside your email.

You likely intuitively know what spam looks like–it’s full of claims that sound too good to be true or otherwise like a scam. Phrases like “100% free” or “guaranteed to work” are the types of email subject lines that will land you in the spam box. Check out this list of 188 spam words to avoid if you need further guidance. An overabundance of emojis can also get your email flagged. As mentioned above, one emoji is great, but seven? That feels spammy!

Finally, those all-caps email subject lines will likely land you in the doghouse, too. There’s a fine line between creating good urgency–the kind that drives up open rates–and just yelling at your audience. A caps-only subject line feels like unnecessary shouting.

Avoid writing email subject lines like this as it will get your message flagged as spam.
