Influencer Mailer Collateral

Kosterina × Olipop × Walmart

Objective: Create a 5" × 7" influencer insert card that feels:

• Fun, elevated, and highly Instagrammable

• On-brand for three distinct partners

• Clear in its messaging while still feeling playful and creator-friendly

Strategic Considerations:

• Ensured visual cohesion across all brands while maintaining Kosterina as the lead voice

• Designed with earned media in mind, knowing the card would likely be photographed and shared

• Worked within a tight timeline, delivering a polished concept quickly to meet production and shipping deadlines

Outcome: The result was a visually compelling mailer insert for 100 influencers showcasing the new Olipop Shirley Temple Flavor alongside Kosterina’s Strawberry Crushed Fruit Vinegar that will be sold in Walmart. See below for some examples of what a few influencers posted to their social media when they received this package.
