The wind is howling... The scariest midnight of the year is approaching... And your Halloween newsletter is lying cold and lifeless, buried in people’s inbox cemeteries, without even being opened... Ooh…That’s probably one of the worst nightmares for every email marketer or brand.
No way are you going to let it RIP there, waving an ultimate farewell to your potential customers and revenues. You just need a new elixir of engagement for Halloween email marketing. And we’ve got a perfect potion recipe for you—wickedly smart spells and sugary sweet ingredients to create engaging Halloween emails for boo-sted conversions and (ideally) sales.
Sip from this cauldron of inspiration, boiling with examples of Halloween email campaigns from other brands, and brew your ideal potion to attract, engage, and convert your audience.
If you’ve been treating Halloween as yet another date on your marketing events calendar, it’s high time to put a priority mark on it.
Here’s why.
How early, you may ask?
Well… what if we told you summer or even spring? Hard to believe, right? Yet, it’s true. In fact, some people start preparing and shopping for Halloween as early as April. Half of consumers do it in July, all thanks to the rise of another event—“Halloween-in-July,” aka “Summerween.”
It’s a splendid chance for you to creep into their inboxes weeks (or even months!) before October to:
Note: Even if you wait till October to launch your creative Halloween email campaign, you may outrun those competitors who “ghost” customers and skip the holiday.
Some numbers whisper, some roar—these roar.
Compared to only $8 billion in 2020, Halloween spending is forecast to break the record and surpass $13 billion in 2025. Being one of the most Halloweenish and feared numbers, it’s strikingly positive if you’re on the business side.
This is yet another reason that makes brands invest in email campaigns during the trick-or-treat season. Halloween takes the bronze and stands alongside Black Friday and Christmas as the absolute trio of champions in terms of time and money spent on them by marketers.
Now, several stats are roaring (again) and proving that Halloween-driven campaigns outperform regular emails when it comes to email marketing metrics. Based on numerous studies, the average outperformance levels are as follows:
Why so?
Because customers are already in the buying mood, let alone when brands do FOMO tricks or incorporate other psychological email techniques to drive sales. Yep, “ends at midnight” can do the trick and evoke the fear of missing out (aka FOMO).
Hey, it’s Halloween! It’s that ghoulish time of the year when businesses are officially licensed to swoosh their magic email marketing wands and say, “I solemnly swear that I am up to no good” in their Halloween newsletters.
You can do the same with:
The best part? You can try the craziest ideas, break nearly all rules (unless maybe they concern morality and ethics), and still tower as a successful sales-booster among your competitors.
Write down all the key ingredients for the spooky season in your holiday email marketing recipe book.
Did you know? A single emoji in the subject line can grab attention and encourage email opens and conversions.
If you don’t want your holiday newsletter to get lost in the misty forest of other emails, add one of the quintessential Halloween symbols like these to your email subject lines this haunting season:
For example:
Look closer at this subject line from a debt relief company: Wipe Out Your Debt Before It Haunts You. See what they did here? Two identical emojis frame it like a magic spell, yet they don’t overwhelm it.
Or—
Here’s another example from a real estate coach: Real Estate Kills… the 9-to-5.
Mind: Not all Halloween emojis have equal power to convert. Some are much stronger than others. For instance, the “spider” icon has a 23% open rate, compared to only 14% when the “skull” emoji is used.
When designing emails for Halloween marketing, make sure to revamp (or “revampire” if vampires are your major theme) each tiny detail.
Let’s say your subject line is screaming “Boo!” In this case, people should likewise feel this spirit in the email pre-header, greeting, and so on. Even your sign-offs (closings).
Get inspired by the following examples of Halloween-style opening lines and sign-offs.
Thinking about a “spooktacular” deal? No, not again! And not for the third year in a row, looking like a zombie drained out of creativity.
Brainstorm some fresher ideas for more playful and engaging Halloween emails:
But of course, no matter how extraordinary and unique your play on words can go, here’s the major trick: stay on-brand.
Here are several Halloween email examples with wordplay in different niches.
See how RushOrderTees did that in the subject line, “No Tricks, Just Tees.” They picked a sound-alike word for “treats,” while offering to “ghost the basic costumes” in favor of corporate-branded tees.
Similarly, NuggMD played with the trick-or-treat phrase for Halloween email marketing in healthcare with the subject line: “Trick or treatment—save $25 on your medical card.”
Now, let’s continue our bewitching pun-tastic flight with Wizz Air. The company nailed their Halloween email campaign in the air travel industry with totally branded wordplay: “HALLOWIZZ,” playing with words “Halloween” and “Wizz”: Get into the HALLOWIZZ spirit—up to 20% off flights!
So, you’ve played (with words). Now, let your audience play. Literally!
For that, add a pinch of gamification to your Halloween newsletter. Consider these bite-sized games to create Halloween emails that engage and convert:
For example:
Check out this interactive email with a boo-bag jigsaw from Purdy’s Chocolatier: “Re-arrange the puzzle pieces to reveal something hauntingly tasty.”
Even the most powerful witches and wizards sometimes need to peek into other cauldrons and eavesdrop on others’ jinxes.
Who makes the best Halloween email campaigns these days? What’s trending? Additionally, you might need to conduct a thorough competitor analysis to understand how your competitors enchant their audiences. What Halloween tricks do they perform in your niche specifically?
Suppose you’re interested in Halloween email marketing strategies for lawyers. In the law practice, brands keep it thematic yet remain professional by providing legal advice and recommendations for the spooky season.
For example:
Catch a glimpse of this newsletter from personal injury solicitors with the subject line: Spookily Simple Halloween Safety Tips.
Now, here are some useful tips and tricks for the “walking dead,” those email marketers who feel totally exhausted without any assistance, neither human nor robotic.
Sure, you can craft a spellbinding email on your own. But why not gather your “coven” to create engaging emails for Halloween (and other holidays, too!)?
Consider expanding your email marketing team and hiring:
For example:
If you’re wondering about the virtual assistant cost, don’t let it spook you. It’s far less than you’d spend on recruiting a full-time worker. And the VA’s best advantage lies in saving you extra hours you can dedicate to strategizing or brewing an effective Halloween email campaign.
Just like broomsticks and cauldrons (and maybe some candles) are necessary for traditional witchcraft, you might need to arm yourself with email marketing software like Mailmunch to automate and analyze your creative Halloween emails. In fact, advanced automation is one of the most impactful trends not only for Halloween but for the whole year, as it contributes to 29.5% email conversion rates.
Here’s what Mailmunch has got in store for email marketers:
Plus, you can explore various holiday email templates at Mailmunch. Need a Halloween sale template? Hocus-pocus
Organizing a trick-or-treat party? Abracadabra—and here’s a template for your fangtastic event.
The greatest part? You can customize and brand them as you witch!
Picked up your digital broomstick? Perfect! Now, let’s fly over to the best Halloween email campaigns from the following brands.
Subject line: Halloween Sale! Fill your buckets
Other tricks:
The UK’s online pet store filled their customers’ inboxes with “scarily good deals” for their boo-tiful pets. As if trick-or-treating, the dog was holding a cute jack-o’-lantern bucket (a tiny but superb animation for emails on Halloween).
Subject line: STARTS NOW: Sigma’s Annual Halloween Contest
Other tricks:
Likewise, tapping into animated email design for Halloween, the beauty and cosmetics company announced the annual makeup contest with this terrific GIF.
Subject line: Halloween Sale Ends Tonight!
Other tricks:
Once upon a Halloween, Postable turned into Postaboo (the wordplay phenomenon, remember?). Plus, the brand tapped into freebie marketing enhanced by the Frankenstein-monster GIF: free stamps with a coupon code that “disappears forever at the stroke of midnight.”
Subject line: Mike Myers Is Back, For One Day Only...
Other tricks:
Have you ever considered an extended Halloween email campaign to engage your customers daily in October?
That’s what the clothing and fashion brand did with the “Daily Doses of Horror,” featuring new product drops and discounts every day of October.
Subject line: LAST CHANCE: 40% OFF HALLOWEEN
Other tricks:
Take a look at another example in fashion email marketing. Dolls Kill designed an engaging animated slideshow of Halloween costumes.
Subject line: Recess x Luxardo Halloween giveaway
Other tricks:
How about inviting customers to your Halloween-inspired Instagram giveaway via email?
Learn from this example. One beverage brand partnered with another, @LuxardoUSA, to give away some products and drive customer engagement on Halloween.
Subject line: SPIN TO WIN!
Other tricks:
Spinning wheels never stop converting customers these days in the best marketing campaigns overall, not only via emails. That’s probably why the shoe brand invited the email readers to spin the wheel and win from 10% to 30% off in this Halloween email.
So, there you have it—the elixir brewed for attracting, engaging, and converting your audience this ghostly season.
