    FAQ

    Asked on almost every call.

    How often does the Backblaze B2 Snap Custom Audience sync run?

    The pace follows your Backblaze B2 files: Signals sends changes from Backblaze B2 to Snapchat each time a new file lands. Because it processes only the newly dropped file, Snapchat audiences that stay in step as the segment rebuilds stays current while teams archiving exports to Backblaze B2 keep list sizing on Snapchat in view. Delivery needs no export and no manual upload.

    What match rate should a Backblaze B2-sourced Snap Custom Audience batch expect?

    Coverage of hashed identifiers across your Backblaze B2 files decides it, and teams archiving exports to Backblaze B2 own that inside Backblaze B2. A live email or phone matches into Snapchat; neither, and it will not. First-run feedback flags list sizing on Snapchat, which teams archiving exports to Backblaze B2 then raise inside your Backblaze B2 files.
