Kettle & Fire was seeing 20–30% email open rates and wanted to reach the 70–80% of their audience not engaging through digital channels. They partnered with Poplar to add direct mail as an offline channel, using Poplar's Klaviyo and Shopify integrations to automatically trigger personalized postcards to lapsed customers in real time as they moved through existing Klaviyo workflows. After early results, the team expanded into triggered campaigns to save time and reach the right consumers across both channels. Poplar reports the program drove over 15x ROAS and a response rate lift of more than 1.4% through direct mail.
