Inflyte does not enforce a strict limit based purely on the number of tracks in a campaign. Instead, campaign capacity is primarily determined by the overall package size of the uploaded content.
Because WAV and other lossless audio formats are significantly larger than MP3 files, we generally recommend limiting campaigns containing lossless audio to approximately 12–15 tracks where possible.
If substantially more lossless files are uploaded, Inflyte may only be able to deliver MP3 versions of the campaign to some recipients.
This is due to several technical considerations, including:
the overall size of ZIP packages generated for downloads
content delivery network (CDN) performance and reliability
Dropbox sync limitations and transfer overhead
download speeds and storage constraints for recipients
maintaining stable delivery performance across large recipient databases
Large campaigns can also negatively impact engagement and feedback performance.
Internal usage analysis consistently shows that tracks positioned further down large playlists tend to receive lower engagement rates, as reviewer attention naturally declines after listening to a certain number of tracks.
For this reason, many labels and PR companies choose to:
split larger compilations into multiple parts
stagger delivery dates
prioritise strongest tracks earlier in the playlist
create more focused campaigns with clearer messaging
In many cases, smaller and more curated campaigns result in better overall listener engagement and reporting quality than extremely large promo packs.
