As someone who has built reverse ETL jobs before tooling for this type of work was largely available, implementing bespoke reverse ETL implementation can lead to ongoing maintenance time snowballing as APIs change, new fields are added, or data grows. Adopting a pre-built reverse ETL tool like Census can automate an otherwise grueling task and save time, sanity, and engineering effort. A dedicated reverse ETL tool empowers the analytics team to focus on business needs rather than technical specs, enabling organizations to send branded and highly personalized communications thanks to the data sent from their warehouse. It's essential to loop in stakeholders early and often, understanding the strategic importance of the data your stakeholders need and finding the easiest and most scalable way to send it from A to B. Collaboration between analytics and business teams is key to defining specs of the reverse ETL process, and communication channels should be kept open post-implementation to ensure a smooth experience for all parties involved.
