Here are the biggest opportunities for your March email marketing content with some nice examples from last year.
Mardi Gras (March 4th)
Considered the American Carnival, Mardi Gras (French for Fat Tuesday), or “Shrove Tuesday” is a celebration of food and happiness, a great opportunity to promote food or products related to cooking. Mardi Gras marks the last day before Lent when Christians fast or give up certain luxuries for 40 days before Easter.
In the UK, the date is known as Pancake Day. In many parts of the United States, famously in New Orleans, Mardi Gras is celebrated with parades and parties in gold, purple, and green.
Dress Day (March 6th)
Dress Day is a simple fun date that does not require overthinking. It is a holiday to celebrate a clothing type (almost) everyone loves. With the start of spring, every clothing brand can boost its warm-weather products.
Day of Unplugging (March 7th)
Today, we can’t escape the conversation about how screen time relates to loneliness and poor quality of life. The Global Day of Unplugging is a movement that asks for a brief pause in the technology-mediated world to connect with people you love.
As this is a recently created holiday, your subscribers might be pleasantly surprised by your email marketing campaign. You can take this as an opportunity to explain the date and how it relates to your brand’s identity, and, of course, to promote your product. For example, if your product is a barbecue grill, you can cue your customers to invite their friends over! Your newsletter can also encourage fun outdoor activities that foster relationships, like hiking or picnics.
International Women’s Day (March 8th)
International Women’s Day can be tricky for marketers, and even backfire if the email content is not made with care. Remember: Women’s Day is all about Women’s Rights. It is a date to celebrate achievements that promote a more just society, like the right to vote and study. Be careful with stereotypes and messages that paint women as just mothers or overly focus on beauty and domestic themes.
How to do it right: International Women’s Day message should be about more than just appreciation. It’s about empowerment for girls and women, achievements, and equal rights. A great idea for a newsletter is to celebrate women in positions of power at your company or to partner with nonprofits and movements that support these efforts.
To really get it right, be sure to read our guides on Women’s Day email marketing and subject lines for Women’s Day that dive deep into this holiday.
This email marketing campaign from Tamara Malas is supporting diversity and inclusivity, the main message being “founded and run by women:”
This email marketing campaign from Ten Thousand Villages opted to highlight Roopa Mehta, CEO of Sasha, one of their suppliers, for a great Women’s Day message:
Mario Day (March 10th)
Mar-10 spells Mario! 😉 This is a fun low-stakes holiday that celebrates everyone’s favorite Italian plumber.
This date is great for any kids or gaming-themed business, such as clothing, furniture, or toys. But even non-related brands can show up to the party of this beloved character with special coupons, trivia, or a heartwarming story for your customers.
Pi Day (March 14th)
Every year Pi Day gains more and more traction. Math enthusiasts recite many digits of the constant π and eat pie. Perhaps the most famous irrational number, Pi has an infinite number of digits without any pattern. For now, it has been calculated to 202 trillion digits.
Many businesses play big on this date with discounts of 31,41% on some or all items of the shop. The main theme is, of course, the old pun, so the public expects newsletters about pies and math jokes on this lighthearted fun day.
St. Patrick’s Day (March 17th)
St. Patrick’s Day started as a religious holiday on the date of the death of Ireland’s patron saint. Today, the festivities, which began heavily influenced by the Irish Diaspora, are more inclusive and lighthearted.
The symbols that you cannot miss in your email marketing campaign are shamrocks and the color green. A lot of brands also include “lucky” themes with sweepstakes or coupons applicable to green products only.

March Equinox (March 20th)
The equinox marks the point when the Sun is perpendicular to the Earth, the beginning of spring in the northern hemisphere.
Although not a big marketing date, the start of spring invites renewal, a great theme for newsletters about clothing and home decor.
World Water Day (March 22nd)
World Water Day has been held since 1993 to raise awareness of the global water crisis. The main themes are access to potable water and sanitation. In 2025, the specific theme is Glacier Preservation.
For your Water Day email marketing campaign, share tips for your customers on saving water, highlight any measure your company has to preserve or treat water, or partner with a nonprofit with this focus.
Mom and Pop Business Owners Day (March 29th)
This date is great for small businesses to take pride in their impact on the economy. There are almost 8 million small businesses in the USA according to the Census, sharing a market that accounts for $142 billion worldwide.
Mom and Pop Business Owners Day is a date to showcase the history and the people who worked hard to grow your business and to show appreciation for local shops owned by community members.
March has some observance weeks that you can use to connect with your audience via a single email or a series of automated emails.

Here are the week-long events in March 2025 that may help your content planning:
March is a special month for brands that focus on women’s and girls’ achievements, and the whole month can feature this theme.

Whether you are a seasoned marketing professional or a DIY kind of entrepreneur, let’s finish with four great tips to help you achieve great results in your March email marketing campaigns.
Know your audience and choose the holidays and events that most align with your brand and subscribers and forget the rest. Your audience wants relevant content, not a calendar reminder! You might need to choose between a well-crafted month-long sequence or specific dates for your campaign.
With segmentation, you can send emails more frequently to the most engaged audience, and be more sporadically to those who don’t click or open everything. Some special dates may be more interesting to only part of your subscribers. For example, sending a unique email marketing campaign only to men on Women’s Day with hints on how they can be supportive of Women in their lives. Another example: On Pi Day, how about a special coupon of 31% off, but only to the top 3,14% of engaged readers?
A lot of event dates are great sales opportunities. If you’re going to slap a coupon and cash in, be sure to optimize everything for mobile: your email marketing message, the landing page, and the checkout process. If something doesn’t look good on the small screen, it’s a lost sale.
Come on, you can’t argue that you didn’t expect Women’s Day in March, right? Prepare ahead and you will have time to select a great photo, copy, and design for your campaign. Even better: once everything is ready, just schedule the campaign launch and let your email marketing system do the sending later!
March has a bit of everything: fun dates like St. Patrick’s and Mardi Gras, curious events like Pi Day or Unplugging Day, and an opportunity to celebrate and empower the women in your company!
If you want your March email newsletters to succeed, these events are a good start. Pay attention to the copy quality, subject line, and best email design practices to ensure deliverability and delight your subscribers.
