    FAQ

    Asked on almost every call.

    How often does the Microsoft Excel Snap Custom Audience sync run?

    You set the cadence, from near-real-time to a nightly Microsoft Excel sync of your Excel workbook rows into Snapchat. Since Signals processes only the newly dropped file, Snapchat audiences that stay in step as the segment rebuilds keeps pace and finance and ops teams working in Excel watch list sizing on Snapchat. One scoped connection sets it up, cadence adjustable later.

    What match rate should a Microsoft Excel-sourced Snap Custom Audience batch expect?

    Match rate follows identifier coverage in your Excel workbook rows, which finance and ops teams working in Excel control, not Microsoft Excel itself. A record with a current hashed email or phone matches for Snapchat; one missing both cannot. First-run feedback from Custom Audiences API pinpoints list sizing on Snapchat, the number finance and ops teams working in Excel tune against.
