​Vanishing Emails is a proprietary marketing solution that significantly reduced CO2 emissions from electronic Customer Relationship Management (eCRM) campaigns by automating the deletion of expired promotional emails. This innovative system uses advanced algorithms to target unnecessary emails like holiday sales and limited time offers, which occupy excessive storage space. By minimizing stored data, it substantially cut energy demands and emissions. Additionally, it employs “carbon equivalencies” to make the environmental benefits tangible to users, illustrating the impact of their contributions on everyday tasks. The solution integrated cutting-edge, serverless AWS technologies and machine learning to enhance user experiences while ensuring mindful technology use that did not aggravate the problem it aimed to solve. Extensive attention to data privacy and security was ensured through third-party accredited testing, making it a sustainable and responsible choice for managing email efficiency.​
