Editor’s Note:
Hi, I’m Layla, Content Producer here at Dotdigital and your go-to for planning your social media calendar. If you’re marketing in Europe or the Americas, August is peak summer. I’m talking: holidays, festivals, long evenings and slower inboxes. South of the equator, it’s a different kind of good news: winter’s finally letting go and warmer days are on the way. Wherever you are, there’s something to celebrate.
This guide will walk you through key themes and observances to help you plan your August social media calendar. We’ve included ideas to inspire not only your social media posts but also your email marketing campaigns too.
Start the month on a sweet note with national chocolate chip cookie day. Food and beverage brands can spotlight chocolate chip-flavored products, share recipe inspiration, or showcase customer favorites. On social media, brands could create cookie-based polls such as “Crispy or chewy?” or “Milk chocolate or dark chocolate chips?” to encourage followers to share their preferences. It’s also a chance for brands to run cookie-making contests, inviting customers to submit their best creations for a chance to win prizes or be featured on social channels.
National bowling day is the perfect opportunity for bowling alleys and entertainment venues to make the most of user-generated content (UGC) in their marketing. Inviting customers to celebrate at your venue and share their experience on social media can help create authentic, engaging content that resonates with potential visitors. For email marketing, this is a great day to drive bookings through targeted offers and themed campaigns.
If there’s ever a day that gives everyone permission to slow down and switch off, it’s national relaxation day. Wellness, lifestyle, and even hospitality brands can use this moment to highlight products, services, or experiences designed to help people unwind, whether that’s at home or out and about. Brands can create “pause and reset”- style content, such as guided-breathing reels, calming behind-the-scenes footage, or even short “digital detox” challenges that encourage followers to step away from screens for a set period.
Not every marketing moment needs a serious angle. National tell a joke day is all about making people smile. Social media content could include industry-themed jokes, pun-led captions, or light-hearted “caption this” posts that invite audiences to get involved. Brands could use humor in subject lines to boost open rates and carry that playful tone through the email itself with jokes or light-hearted hooks.
National radio day celebrates one of the most influential forms of media, offering brands a chance to tap into nostalgia. Brands can lean into audio-themed content, such as sharing favorite radio moments, spotlighting team playlists, or running “what are you listening to?” style polls to create engagement. This could also include content designed to fit into everyday routines, like commuting or working.
National banana split day serves up a chance for brands to embrace playful content that captures the joy of a classic ice cream. Food and beverage brands can spotlight banana split-inspired products, limited-edition flavors, or recipe ideas that put a modern twist on the classic dessert. It’s also a great opportunity to tap into visual, mouth-watering content that performs well on social media, from close-up imagery to short-form videos showing how the treat is made.
Dogs bring instant joy and engagement to your social media, making national dog day a perfect moment for brands to lean into pet-led content. Encouraging followers to share photos of their dogs using a branded hashtag can help build a sense of community, while reposting customer or employee pet content adds an authentic, human touch.
