October has arrived, and so has the annual invasion of Halloween marketing emails.
Your inbox is now faced with an onslaught of “spooktacular savings,” “fang-tastic deals,” and enough pumpkin emojis to make a Starbucks marketing executive weep with joy.
Somewhere in there, a brand has promised a “SCARY GOOD SALE” that turns out to be 10% off orders over $150.
Terrifying indeed.
Halloween gives marketers a wonderful excuse to get creative, have some fun and experiment with campaigns that might feel out of place the other 11 months of the year. But with every retailer, restaurant and e-commerce brand fighting for a piece of the seasonal excitement, an orange subject line and a cartoon ghost just aren't going to cut it.
The best Halloween email campaigns understand a little something about human psychology. They create curiosity, reward attention and give people a reason to engage. And the worst ones? Well, let’s just say that some marketing decisions are scarier than anything you'll find in a haunted house.
Here's how to keep your Halloween email marketing firmly in the treat category.
DO: Give Your Subject Lines a Little Personality
Halloween is practically begging marketers to have fun with subject lines. You have an entire vocabulary of ghosts, tricks, monsters, midnight mysteries and forbidden treats at your disposal. Use it!
But remember that your subscribers have probably received six variations of “Spooktacular Savings Inside!” before they've finished their morning coffee, and after a while, that gets stale.
A good subject line creates curiosity while giving readers some idea of what they'll find when they open the email. Try using wordplay that fits your brand or creating a little intrigue around an offer.
For example:
-
A Little Something Wicked This Way Comes works for a beauty or fashion brand teasing a new collection.
-
Your Cart Has Been Haunting Us gives abandoned-cart emails a seasonal twist.
-
We've Got Skeletons in Our Closet. They're 40% Off. could be a fun way for an apparel brand to advertise clearance.
-
Open If You Dare (There's Chocolate) is appropriately ridiculous for a candy company.
Keep the preview text working alongside the subject line, too. It's valuable space for introducing the offer, adding context or delivering the punchline.
And please, spare your readers the parade of ALL-CAPS SCREAMING and fifteen exclamation points. Nobody needs an email that looks like it was written by a panicked Victorian ghost.
DON'T: Dress Up a Bad Offer and Call It a Treat
Consumers know the difference between a great deal and an ordinary promotion wearing a plastic vampire cape.
If your Halloween email promises a terrifyingly good discount, the offer had better deliver. A confusing promotion with six exclusions, a $200 minimum purchase and an expiration date buried in the footer isn't exactly a treat.
There's a psychological principle at work here called expectation disconfirmation. People evaluate experiences partly by comparing what they expected with what they received. When the gap is disappointing, satisfaction suffers.
This applies directly to promotional emails. An exciting subject line raises expectations, and an underwhelming landing page immediately deflates them.
If you're offering 20% off, say so. If the sale only applies to select products, make that clear. And if you don't have a discount worth celebrating, consider another reason to reach out. A costume contest, exclusive product preview, Halloween recipe or interactive quiz can give subscribers something enjoyable without requiring a markdown. Sometimes the best treat is an email that's genuinely entertaining.
DO: Segment Your Audience Before You Unleash the Monsters
Imagine sending an email promoting adorable toddler costumes to a subscriber who has spent the past three years exclusively purchasing industrial power tools.
Unless they're planning a very unusual kind of Halloween party, you've probably missed the mark.
Halloween offers plenty of opportunities for personalization, but only when you understand what different customers want.
A retailer might separate subscribers into costume shoppers, home decorators, candy buyers and customers who primarily purchase everyday products. Each group could receive a different creative treatment or offer. Returning customers might appreciate early access, while recent browsers could receive recommendations based on what caught their attention.
This is particularly important for seasonal marketing. Someone who buys from you every month shouldn't have to endure three weeks of irrelevant pumpkin promotions just because they happen to be on your email list.
Seasonal campaigns should complement existing customer relationships rather than overwhelm them.
You can even let subscribers choose their own adventure. An early October email asking whether they're shopping for costumes, decorations, or treats provides useful preference information for the rest of the campaign. And that's a much better use of personalization than inserting someone's first name into a subject line and pretending you've developed a close personal relationship.
DON'T: Turn Halloween Into a Monthlong Inbox Horror Movie
One Halloween email? Fun.
A handful of well-timed Halloween messages? Perfectly reasonable.
Twenty-seven increasingly desperate reminders that your pumpkin-themed clearance event ends at midnight? Congratulations, you're now the villain.
Email fatigue happens when subscribers receive more messages than they're interested in reading. Engagement can decline, unsubscribes can increase, and spam complaints can damage your sender reputation.
The tricky part is that Halloween gives brands several legitimate reasons to send messages. There's the early announcement, the product showcase, the special offer, the last-minute reminder and the inevitable “one more chance” email.
Before you schedule all five, consider whether each one offers something meaningfully different.
A practical Halloween email sequence might start with an early October teaser, follow with a product or offer announcement and conclude with a carefully timed reminder. More engaged subscribers could receive additional messages based on browsing or purchase behavior.
If someone has already purchased the Halloween costume you're promoting, stop asking them to buy it again (unless your campaign is specifically aimed at people who need twelve inflatable dinosaur costumes, in which case we'd love to hear that story).
Use engagement data and frequency controls to decide who receives additional messages rather than treating the entire list as an audience that's obligated to participate in Halloween.
DO: Use a Little Fear, but Know When the Joke Stops Being Funny
Halloween is one of the few times brands can deliberately make customers feel uneasy and expect them to enjoy it. The reason for that is relatively simple: People often enjoy fear when they know they're safe. Haunted houses, horror movies and roller coasters create excitement by offering controlled experiences of uncertainty.
Marketing can borrow that idea through playful suspense, mysterious product reveals and the anticipation of discovering an offer. A subject line that says “Something's Lurking in Your Cart” might be fun for a Halloween promotion. A countdown leading to a surprise product drop can create anticipation. A spooky visual reveal might make an otherwise ordinary announcement memorable.
But there's a difference between playful suspense and exploiting someone's anxiety. As we explain in our look at the psychology of fear in advertising, fear can be a powerful way to capture attention, but manufactured emergencies, misleading scarcity claims and intimidating messages about what customers stand to lose can quickly undermine trust.
One useful test: Would the recipient enjoy the joke after realizing what you're selling?
If the answer is no, your marketing might need an exorcism.
DON'T: Make Customers Solve a Mystery to Find Your Offer
A Halloween scavenger hunt can be great fun. A checkout process that feels like one is considerably less charming.
You might have created a beautiful email with animated bats, flickering candles and a delightfully creepy headline. But if the discount code is hidden halfway down the page or the call to action disappears into the dark purple background, all that creativity is working against you.
Halloween email design still needs to follow the basics of good user experience. Keep the primary CTA easy to find, make text readable and test the layout on mobile devices. If you're using GIFs or animation, make sure the message still works when images don't load or motion is reduced.
And resist the temptation to make every element interactive. A fun email shouldn't require subscribers to spend five minutes figuring out how to shop.
Consider the connection between the email and its destination, too. Someone who clicks on “Shop Our Haunted House Collection” shouldn't land on your generic homepage and have to track down the products themselves. As with any good e-commerce advertising strategy, the transition from an ad to its landing page should feel seamless. Someone who clicks on “Shop Our Haunted House Collection” shouldn't land on your generic homepage and have to track down the products themselves.
Save the jump scares for the movies. Your conversion path should be pleasantly predictable.
DO: Get the Timing Right, Even If Halloween Isn't Your Biggest Holiday
Here's a particularly cruel trick marketers play on themselves: spending three weeks perfecting a Halloween campaign and launching it after customers have already bought their costumes, decorated their homes and eaten half the candy.
The timing ultimately depends on what you're selling. Costume retailers need to account for browsing and shipping, while restaurants promoting Halloween events can reach customers closer to the date. Candy brands might even benefit from last-minute shoppers.
Our research on early holiday shoppers found that more than 45% of consumers begin their holiday shopping before November. While that research covers the broader holiday season, it's a useful reminder to plan around customer behavior rather than your marketing calendar.
Review past purchase patterns and shipping deadlines before scheduling your emails. And if you're planning an October 31 flash sale, consider whether your customers will be checking their inboxes or escorting tiny vampires around the neighborhood.
DON'T: Forget That November 1 Exists
There's a certain desperation to the final hours of Halloween marketing. Discounts grow larger, countdown timers multiply, and inboxes begin to resemble the closing scenes of a horror movie.
Then midnight arrives, the pumpkins go into the compost and marketers immediately move on to Black Friday.
But Halloween campaigns can provide valuable information about customer interests and behavior. Those insights shouldn't disappear with the decorations.
Look beyond open rates when reviewing performance. Which segments purchased? Which offers generated incremental revenue? Did your Halloween campaign attract new customers who might buy again, or did existing customers simply shift purchases they would have made anyway?
Compare campaign revenue with discount costs, creative expenses and any paid media supporting the promotion. Review unsubscribes and spam complaints alongside conversions. A campaign can produce strong short-term sales while damaging the audience you'll need in November and December.
And don't overlook the opportunity to follow up. Someone who purchased Halloween decorations might be interested in seasonal home décor. A first-time candy buyer could become a repeat customer with the right introduction to your brand.
Halloween may last one night, but the customer relationships you're building should survive considerably longer.
Give Your Subscribers Something Worth Opening
Halloween offers marketers a rare creative playground. You can be spooky, silly, mysterious or just a little weird without having to explain yourself quite as much as usual.
Take advantage of it. Write the ridiculous subject line. Have fun with the creative. Surprise your subscribers with something they didn't expect.
Just remember that even the cleverest Halloween email has to earn its place in someone's inbox. A relevant offer, thoughtful timing and an enjoyable experience will do far more for your campaign than another “fang-tastic” pun.
