How often does the AWS S3 Snap Custom Audience sync run?
You set the cadence, from near-real-time to a nightly AWS S3 sync of your S3 exports into Snapchat. Since Signals processes only the newly dropped file, Snapchat audiences that stay in step as the segment rebuilds keeps pace and data teams landing exports in S3 watch list sizing on Snapchat. One scoped connection sets it up, cadence adjustable later.
What match rate should a AWS S3-sourced Snap Custom Audience batch expect?
Match rate follows identifier coverage in your S3 exports, which data teams landing exports in S3 control, not AWS S3 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 data teams landing exports in S3 tune against.
