Specify filter rules to delete or exclude
Redact has 4 types of filters for Emails; Seen, Answered, Flagged, and Draft. When selecting these types, ‘.’ means that the tweets will only be targeted by Redact if you otherwise have rules that include it. ‘-’ means that you want Redact to skip over the that type or you mean to KEEP that. ‘+’ means that the tweets MUST be included in the deletion.
