West Coast-based alcohol delivery mobile application Saucey prompted higher in-app sales following its use of a conversion tracking tool and a targeted email campaign featuring a promotional code. The delivery app teamed up with app marketing automation firm Appboy to track the effectiveness of a user engagement campaign which sent an email with a promotional code to users that had recently made a purchase within the app. The campaign resulted in the targeted consumers making purchases 25 percent faster than consumers who did not receive the advertisement.
