Key events for April newsletters

Let’s explore the biggest holidays in April and the most exciting special events, examples and best practices included!

First week of April

April Fools’ Day (April 1st)

April Fools’ Day (“Lie Day” in some countries) is a great opportunity to show the funny side of your business. Some play it big on the date, doing fake product launches with videos, images, and even websites! If you’re unsure, keep it simple for your newsletter (or skip the date) like a funny subject line.

Bogus products can be a good way to feature the real ones. This fake selection of dates for “situationship” by The Adventure Challenge (with featured bad reviews 🤣) was a good way to showcase their real date suggestions for couples.

There’s always room for playful jokes, such as the Banana Seats for bicycles from Huffy or the Floppy Disk to tune cars from USP Motorsports:

The classic ‘We’re not joking’ angle is safe, but it’s common. If you use it, add a fresh twist (a surprising headline, a mini-story, or a unique offer framing).

For example, you can include some absurd news just in the subject line to increase the chances your email gets opened, then deliver the “April’s Fools'” punchline in the body of the email.

Quick tip: Avoid fake promotions or discounts or bogus products too similar to the existing ones, as these have the potential to enrage your fans with failed expectations.

DIY Day (April 2nd)

A date to celebrate hobbies, home projects, and crafts, DIY Day is very special for brands that align with this motto, such as tools and kits for hobbyists and enthusiasts or arts and crafts stores. These brands can go big on this day with great coupons and promotions.

There are other ways to mark the day. For example, Converse promoted its customizable shoe line with a 25% off coupon. The email marketing campaign showed how to customize your All Stars (colors, logos, and custom embroidery). It’s a nice email that celebrates the DIY spirit by highlighting this special line of custom products.

Walk to Work Day (April 4th)

Walk to Work Day is a date to remember the benefits of everyday walking. Based on 2024-2025 U.S. Census Bureau American Community Survey (ACS) data, approximately 69.2% of American workers aged 16 and older drove alone to work, which increases emissions and impacts public health. Even if your customers can’t walk the whole way, this date can be celebrated with invitations to walk to a nearby bus or metro station or even to a colleague’s house to carpool. Or, the office can celebrate with a nice walk to a neighborhood restaurant for lunch.

This date is, of course, an opportunity for shoe brands and some environmentally-oriented companies. Snibbs showed how simple and beneficial it can be and how comfortable you can be wearing their shoes.

Easter (April 5th)

Easter is, of course, the big date for April 2025. Although a Christian holiday, Easter has also evolved into a broader seasonal celebration in the forms of chocolate eggs and the Easter Bunny, a family tradition that can be enjoyed by everyone.

Many cultures celebrate Easter with a feast (that traditionally ends Lent), with family gatherings and the distribution of chocolate eggs, a modern version of the custom of decorating eggs for the season.

There are many ways to celebrate Easter in your marketing planning, from a simple Easter email message with wishes of abundance to a special Easter flash sale.

Promoting a virtual egg hunt is another popular Easter email marketing campaign, offering discount coupons (or eggs) hidden on the brand website for the customers to hunt for. The egg hunt can also happen in the email body, hidden with small letters, light grey text on a white background, and other tricks.

CSIRO Diet company and Prime Cabinetry went with discount coupons, with “bunny and egg” themed emails.

O My Bag and LaBante promoted virtual egg hunts on their main websites, inviting customers to search for eggs to discover the promo code. O My Bag also highlighted that one of the eggs was on their sustainability page, highlighting that feature of the company.

Self-Care Day (April 5th)

Self-care goes beyond products, so lead with value (tips, routines, resources), then pair it with a relevant offer.

In marketing strategies, the April 5th date is important for cosmetics and spa-related companies since we’re talking about self-care. The best approach is the simplest: to use the date as an excuse for encouraging personal care. Add in a great promotion or coupon to increase sales and clear remaining stock.

DudeRobe newsletter reminded men to kick back and chill like a boss, while Skincare Essentials promoted their subscriptions with a 40% off coupon just for the date.

Second week of April

Pajama Day (April 6th)

Pajama Day is a whimsical day to praise the most comfortable clothing. It is celebrated with pajama parties, family activities, and even “wear a pajama day” at the office!

Kids’ and clothing brands are the most fitting companies to advertise this day, but even non-related brands can jump in on the fun. What about a photo of your team in pajamas?

Little Adventures is a children’s clothing brand that selected its Princess Nightgown line for the Pajama Day email marketing campaign, with a huge photo and discount coupon.

Unicorn Day (April 9th)

A fun, whimsical occasion, Unicorn Day is a special date to celebrate the most cherished magical animal. Did you know that the unicorn is also Scotland’s national animal?

Unicorn Day is all about shiny childhood happiness for everyone. So get your glitter ready and write a marketing email that sparkles!

Fifth Sun opened the day with a great subject line that captured the attention of even the most unicorn-skeptic: Eat Glitter for Breakfast? 20% Off Today Only! ✨

Pet Day (April 11th)

National Pet Day celebrates the animals that keep us company, big or small, furry, feathered, or scaly. Most American homes (66%, as per the American Pet Products Association) own at least one pet, according to the American Pet Products Association.

Dogs are the most popular pets, followed by cats and fish. Pet ownership is also big business: according to the American Pet Products Association, the US Pet Industry made $157 billion in 2025.

National Pet Day is a great date for pet products and pet care emails, of course. It can be very lucrative to remind your audience that it’s their best friend’s day, and their furry companion deserves a nice treat or a new bed.

Under the Weather Pet, a food and supplement brand, celebrated the date with a 20% off coupon for online purchases, valid for one day only.

Many industries also have a “pet line” to match their human-size products, like bedding, clothing, or sports gear. That’s the date to advertise that! For example, security camera company Time2 used Pet Day to advertise pet monitoring cameras in its newsletter. 

Third week of April

World Art Day (April 15th)

World Art Day was proposed by the International Association of Art on April 15th, the date of Leonardo Da Vinci’s birthday, as a day to celebrate art, peace, freedom of expression, and multiculturalism.

Your marketing campaign for World Art Day can be an excuse to talk about art in any form and inspire your subscribers. Crafts and art supplies brands can jump in with discounts and supporting local artists, while design-related companies can write about classic or contemporary artworks and artists that inspire the collections.

Mous is a company that produces phone cases, bags, and pouches. The brand’s World Art Day email marketing campaign highlighted their Mous Collab collections, which feature artwork from artists from around the world.

Banana Day (April 16th)

Banana Day is a fun witty day celebrating the Minions’ favorite fruit. While there’s not much to unpack here, if you can think of something banana-related for this day, it will surely spark joy in your customer’s day.

While it doesn’t mention the date, Brazilian clothing brand FARM Rio’s email on April 16th is all about beautiful banana prints in shirts, dresses, and trousers.

Exercise Day (April 18th)

Every year, Exercise Day encourages everyone to exercise for fun and health benefits on April 18th. You can join a gym, go to sports classes, or run to the park for some outdoor fun.

You can explore activity, health, sports, and community sub-themes in your email marketing messages.

Old School Labs is a supplements brand that offered a 25% off coupon store-wide on Exercise Day, with the message “sweat, save, and celebrate.”

Fourth week of April

Earth Day (April 22nd)

Earth Day, first held in 1970, is a date to remind everyone of the necessity for environmental protection and collective action for the sustainability of the planet.

The 2026 theme is “Our Power, Our Planet,” to demand rapid clean and renewable energy deployment and to foment discussions in schools, communities, and industries.

So, your Earth Day email marketing should focus on sustainability. It is an opportunity to showcase what your company does to reduce or eliminate the impact of product production and transport. This year, a nice touch is to remind your customers that your factory, store, or office is powered by clean and renewable energy if that’s the case.

US Parks Project launched a special Earth Day collection featuring upcycled national parks and wildlife designs.

International Design Day (April 27th)

International Design Day has been celebrated since 1995 as a day to notice the impact of design in everyday life. Design can be diverse, functional, beautiful, colorful, or transparent.

Design is important for every brand, as it impacts sales, usability, and sustainability. Good design can transform the relationship between customer and company. That’s why the best way to celebrate Design Day in your email marketing message is to show why design matters.

A nice touch is to celebrate the internal team of designers that make your product shine. That’s Cossato’s email marketing campaign, featuring how their team of designers makes the baby products their customers love.

Fifth week of April

International Dance Day (April 29th)

Created in 1982, International Dance Day celebrates the art of the moving body in rhythm, solo or collective, choreographed or spontaneous.

It can be celebrated with free workshops and discounts on dance-related items such as shoes, leotards, and (why not?) disco balls.

IMBODHI is a clothing brand focused on onesies and comfortable clothing that many dancers and Yoga practitioners like. They celebrated International Dance Day with a cute email featuring women dancing and a button call-to-action “move freely.”

Tips to make your April newsletters irresistible

Every email marketer can learn a few new tricks to improve their game.

Write with your audience in mind

Every brand channel has a persona — an idealized version of a member of the public. Great content is written with that fictional client in mind, like an email just for them. Keep this in mind, and you’ll have a greater chance to connect with people.

Send more than one email (sometimes)

If you’re thinking, for example, of an egg hunt campaign, why limit it to a single email? You can hide eggs or hints in every April email until Easter and boost opens and clicks across the campaign. You can even send the next emails only to those who found the first one using a drip campaign.

Personalize for effectiveness

I know that your company’s Earth Day email was not written just for me. But personalization can be a huge deal if your company has access to customer data. It can be as simple as a customer name on top and as complex as a curated playlist for Exercise Day according to customer data. Be creative to win the client’s heart.

Final thoughts: Mother’s Day is in May!

So, we’re all about April, and you think I’m getting ahead? But Mother’s Day is just around the corner, on May 10th. Many companies  go big on Mother’s Day campaigns in April to account for decision and delivery time. Consider starting in April to allow time for planning and shipping, and don’t forget to consult our holiday calendar.

April is all about movement and arts, with a big chocolate bunny right in the middle of the month. Of course, you won’t select every date we highlighted here, just the ones that make sense for your company. The good news is that April has a bit of everything!
