5 campaign ideas to celebrate International Friendship Day

Memorable campaigns often revolve around a theme, and what better theme is there than friendship?

Celebrating International Friendship Day with your customers not only aligns your brand with positive, universal values, but also provides an excellent opportunity to engage and grow your customer base.

Here are five inventive campaign ideas that ecommerce stores can use to celebrate International Friendship Day and turn it into a marketing success:

  • Friendship Day-themed product/collection. Release a limited-edition product or collection themed around Friendship Day. This can create excitement and a sense of urgency among your customers to purchase before the special edition items sell out. You can further promote this by sending an exclusive email preview to your subscribers before the general public gets access.
  • Refer a friend. Encourage your customers to refer a friend to your online store by providing both the referrer and the referred friend a discount on their next purchase. This is a classic strategy that gains new customers while rewarding your loyal ones.
  • Best friend bundles. Create special “Best Friend Bundles” of products that can be shared between friends. These could be matching items or complementary products that encourage the spirit of friendship and sharing.
  • Buy one, gift one. Launch a “Buy One, Gift One” campaign where every purchase enables the customer to send a similar item as a gift to a friend at a discounted price or even for free. This not only drives sales but also helps spread the word about your brand among your customers’ friends.
  • Collaborate with a cause. Partner with a charity or cause that aligns with your brand’s values and announce that a portion of all Friendship Day sales will be donated to this organization. This not only generates sales but also associates your brand with compassion and social responsibility – traits that resonate strongly with many consumers today.
