Email Marketing on Halloween: The Ultimate (and Spooky) Guide [2026]

Another year is approaching October 31st, the date on which Halloween is celebrated. Despite being a popular holiday in Anglo-Saxon countries, globalization has led to it being increasingly widespread in the rest of the world, which is why it’s worth doing email marketing on Halloween.

In recent years, it has become increasingly common to celebrate it in our country as well, and by extension, it has become another date to add to the editorial calendar of companies’ marketing campaigns.

That’s why we’ve written this guide to help you prepare your Halloween mailing campaigns as efficiently as possible.

Why do email marketing on Halloween?

As you probably know well, seasonality is a very important factor to consider if you have an online business. For many sectors, there are several key dates throughout the year when sales skyrocket, and it’s worth concentrating more marketing efforts on them to make the most of them.

Depending on the sector, your business may be more or less susceptible to seasonality, but it’s very likely that you shouldn’t lose sight of it, especially if you have a B2C business (and I won’t even mention if you sell pumpkins).

In addition to traditional dates (Christmas, Easter, sales, etc.), in recent years, other dates that we have adopted from other countries have become popular. A clear example would be Black Friday or Cyber Monday. In recent years, Halloween has gained great popularity in our country.

Including dates like these in an email marketing calendar offers several advantages, and this holiday, in particular, has the following:

Subscribers more receptive to messages

On these key dates in the calendar, users are more receptive to brand messages, as they usually send different communications and make interesting offers.

Opportunity to be creative

If there’s one holiday where you can be a little “naughty,” it’s undoubtedly Halloween. Its imaginary world filled with monsters, fantasy, and “pop” culture allows for much more creative freedom than on other occasions since almost anything is allowed.

Take advantage of spontaneous purchases

Since it’s not a holiday that has been established for long in our country, you can create a need in consumers that they might not have anticipated, leading to a more impulsive purchase than usual. Do you have a store? Offer them the best products to organize a party. A hotel? What better way than a spooky Halloween trip. Do you sell makeup? You’ll be perfect for their costume party…

What to do and what not to do in your Halloween emails

Once you’ve planned your strategy, it’s time to define it. Here are some tips on what you should and shouldn’t do in your Halloween campaign:

Do: Use humor and the appropriate tone for the holiday Don’t: Maintain a tone that’s too serious (or go overboard with excessively loaded language that becomes incomprehensible)

Do: Use the date to send a relevant message with a specific goal (sales, loyalty, acquisition…) Don’t: Send a campaign with nothing to say just because “everyone else is sending one”

Do: Keep the campaign’s goal and CTAs clear Don’t: Dilute the final message with excessive references to the holiday or include too many clickable buttons.

Do: Adapt the design with Halloween-related motifs and colors Don’t: Use the same template and colors you use for regular mailings

Create your Halloween email strategy

The fact that a date worth considering in marketing campaigns is approaching doesn’t mean it’s enough to send an email on that day. It’s worth carefully calculating who, how, and why you’re going to send that campaign or campaigns to ensure the best open rate and the highest possible return on investment.

Timing and sending cadence

As with any email campaign, the time or times you choose to send are crucial. I have bad news, you’re not the only one who thought of sending a special Halloween campaign. If you don’t want to be buried (alive) among the other emails in the avalanche, you’ll have to choose the timing of your send correctly. How? By knowing your audience and their schedules or using the send-at-the-best-time mode for each subscriber offered by Acumbamail PRO. Just like in a good horror movie, you must perfectly choose the moment to give your audience the “scare” for it to work.

Pay special attention to the cadence of the sends as well: A single send on the 31st? Previous sends generating anticipation? Adding a follow-up send? An extra reminder SMS for those who didn’t open the email? These are important decisions you’ll have to make based on the type of campaign and the goal you want to achieve with it.

Segmentation

This is a maxim of email marketing not only valid in this case but always: not everything you send should be sent to all your subscribers. If you choose the right segments for each email, interest will increase, and you’ll get more opens, more clicks, and, of course, more sales. Therefore, think carefully about who you’re going to send what to make your campaign or campaigns much more effective.

Design and content

Take the opportunity to give your template a spooky or fun touch, instead of using the usual one. It’s a special occasion, and that should be reflected in the look and feel that reaches your subscribers. Of course, with the same rules as always: responsive, balance between image and text, avoid words that trigger spam filters… You don’t want to be the one getting the scare.

You can also rely on AI to generate illustrations or text drafts, always reviewing them before sending, of course.

Add value

Don’t send a Halloween campaign just for the sake of sending it. If you have nothing to say, your subscribers will appreciate silence more than another empty newsletter that doesn’t offer them anything at all. Think carefully about what to offer and why they should pay attention to your email and not the dozens of others they’ll receive on this date. A discount? A gift? A flash offer?

Tricks and tips

Subject and copy

The subject is the first thing your subscribers will read and what will primarily determine whether they open the email or not. Try to give it a fun, mysterious, or spooky touch so that from the first moment they know it’s a special campaign that contains something interesting for them.

Continue with the same tone inside the email, don’t bore them with overly formal text now that you’ve caught their attention. However, don’t go overboard exaggerating the language or you’ll sound like Mr. Burns dressed as Jimbo.

If you run out of ideas, an AI tool can give you dozens of subject line variants in seconds. Choose the best ones, adjust them to your tone, and test them with an A/B test.

Trick or treat!

One of the most popular Halloween activities is dressing up and asking for candy in the neighborhood houses. Why not be the one to give your subscribers a treat?

A Halloween-themed freebie can be a great idea to capture their interest and thank them for their loyalty. For example, we’ve prepared some free resources for you to use in your mailing campaigns on this occasion.

Spooky offers and promotions

Since you’re going to send a special campaign, make it worthwhile and offer something truly interesting. Think of an attractive discount, a bundle, or an exclusive product.

Resurrect the zombies or eliminate them for good

It might be a good opportunity to send a campaign to those inactive users for a long time. This way, maybe some will come back from the dead, or you can eliminate them from your database for good, stopping sending to users who aren’t interested in your products or services.

And if they don’t open your emails, try reaching them via SMS: sometimes it’s the push they need to come back from the dead.

Reward loyalty

Capturing new users is great, but don’t forget about those you already have. Everyone appreciates being remembered when they’ve been using a service or shopping at a store for a while, so you can take advantage of this date to give them some kind of reward.

Generate a sense of urgency, anticipation, or suspense

A countdown, a series of mysterious emails, or a “scratch and win” can be some good ideas to increase interest in the campaign. However, if you play this card, make sure to meet the expectations you generate.

And if you want to make sure no one misses the offer, reinforce the email with an SMS on the 31st: it’s a channel with very high open rates, ideal for the last notice.

Use social media

Since you’ve created the campaign and the resources to carry it out, take advantage of it to spread it on social channels as well and gain traction and virality through this route. If you do something eye-catching enough that invites sharing, you can get a lot of traffic.

Measure the results

As with any other campaign, check the metrics, analyze the impact it had, and draw conclusions for next year. What can be improved? What were the successes?

Campaigns to inspire you

Below, we select some campaigns that caught our attention for their design or originality and can serve to give you ideas:

Whistlefish

The gift card page doesn’t abandon its style but adds a childlike Halloween touch and a mysterious promotion with a coupon you must discover by entering a page on their website.

Fresh Picked Deals

This online store opts to offer free shipping and adds an animated image in the template.

Mango

Adapting an email template for Halloween doesn’t mean giving up style and elegance. In this case, the Mango store added hand-painted costumes to the photographs of their products.

Hotel Chocolat

Sweets are one of the main protagonists of this holiday, and the Hotel Chocolat store takes advantage of the occasion to offer specific themed products for this date.

Loft

An original idea is Loft’s, which focuses on treats but with a design that’s not “spooky” at all and a slogan that plays with the holiday’s leitmotif that says: “Only treats, no tricks”

J. Crew Factory

Another example of an elegant theme despite being adapted to the date, with an iconic ghost and the phrase “Trick or treat?”

Jack Threads

A clear example of total adaptation to Halloween, with bone-shaped letters, bloodstains, and a “jack-o-lantern” pumpkin, a promotional code to get a discount.
