For food delivery services: Let customers “create their dream dish” by choosing unique ingredients for their meals.

Send your customers an email campaign offering them the opportunity to create their dream dish. Run a promotion like “Create your Dream Pizza/Sushi/Burger/Salad”. Let customers choose their ingredients and create unique dishes. 

For online education: Offer special discounts on online courses or free consultations with experts.

Help your customers achieve their educational dreams. Offer special discounts on online courses, include them in giveaways of free consultations with experts, or host a webinar on topics that interest your subscribers the most. Inform your subscribers about the promotion via email campaign. 

For fitness centers: Give clients a free trial or an exclusive event to help them achieve their fitness goals.

Give your customers the chance to try any available fitness program for free during this day, or organize an exclusive event where they can make their fitness dreams come true. Launch this promotion through a dedicated email campaign.

For online retailers: Market your products as tools for fulfilling wishes.

Present your products as tools for fulfilling cherished wishes. For example, organize a “Buy Your Dream” email campaign with discounts or gifts with the purchase of specific items. 

Daughters Day

A touching occasion to promote products for girls or to send a heartfelt message to your subscribers.

Comic Book Day

An obvious choice for comic book stores or brands with a playful, creative identity.

Cooking Day

Perfect for kitchenware brands, food subscription boxes, or online cooking classes.

One-Hit Wonder Day

One-Hit Wonder Day is a fantastic opportunity for a creative marketing campaign. Instead of featuring artists with only one hit, you can use the opposite idea: timeless classics.

Showcasing merchandise from iconic bands like KISS allows you to build a powerful contrast. Use a headline like “From One-Hit Wonders to All-Time Greats.” This clever angle positions your product as a legendary item that will last longer than a fleeting trend. Your campaign can be a celebration of both the fun nostalgia of one-hit wonders and the enduring appeal of the artists in your collection.

Women’s Health and Fitness Day

A key day for health, wellness, and fitness brands to run a major campaign. Offer discounts on gym memberships, supplements, or athletic wear.

📆 September 28th

Ask a Stupid Question Day

A wonderful opportunity to address any pre-purchase hesitation and discover how customers truly feel about your product. Send out a feedback survey, keeping it lighthearted if it aligns with your target audience: “We know asking ‘Did you like it?’ sounds a bit cliché (mostly because we really want to believe the answer is a resounding ‘Yes!’). Even so, it’s incredibly important for us to know if you’re happy with the product, delivery speed, and overall service.”

To build your survey effortlessly, you can use our preset email templates.

International Day for Universal Access to Information
