Dunkin's ProDUNKtivity Week Distributed Free Coffee, Offers Free Doughnut

Dunkin' kicked off ProDUNKtivity on Dec. 29, 2025 by releasing one million codes for a free coffee, a drop intended to drive app engagement and give customers a quick win during the holiday stretch. The codes were distributed through the Dunkin' app and were fully redeemed the same day, underscoring the appetite for short-term, app-driven promotions among coffee buyers.

The promotion extends into early January 2026 with a Jan. 2 offer that gives customers one free classic doughnut with the purchase of any beverage. Dunkin' said redemption details for that doughnut will be posted to its official Instagram account, so customers planning to claim the deal should check the brand's Instagram for the step-by-step instructions and any location-specific notes. The ProDUNKtivity week also includes a merch sweepstakes and other giveaways across the promotion period, while the chain continues to keep seasonal menu items available for those looking for familiar holiday flavors.

For readers looking to take part, the practical steps are straightforward: have the Dunkin' app installed and an account ready for app-based redemptions, and monitor Dunkin's Instagram today for the doughnut redemption announcement. Because the initial million-code drop was exhausted in a single day, customers who want to benefit from time-limited promotions should plan for potential surges in participation and act early once details are posted.

This campaign has community-level relevance beyond free treats. Local coffee routines and morning commutes can be nudged by these one-day offers, creating small local spikes in foot traffic that matter to store teams and regulars alike. Budget-conscious customers get a short-lived price break, and the merch sweepstakes offers an extra engagement point for fans who follow the brand on social channels.

Dunkin' framed ProDUNKtivity as a week of celebratory giveaways that tie app use and social engagement to in-store visits. With the initial coffee codes already claimed and new redemption details arriving on Instagram, now is the time to check the app and social feed if you want to participate before the promotion concludes in early January.
