We now support syncing headerless delimited format files (CSV, TSV, log) for Email connectors. We will create generic column names for CSV files without a header line. This feature is in beta and available to all customers. See the configuration options in our files documentation for details.
When we encounter malformed files during our syncs, we now skip them and send you a warning so that you can fix the files in question. Previously, our entire sync would fail if malformed files were present.
