Why standard spreadsheets and manual sorting fail on Catchall & Spam Trap Cleaner
The Latency & Fatigue Bottleneck
When operations or revenue teams download raw data dumps with 2,000 to 25,000 rows, team members spend an average of 4.5 hours manually skimming rows, applying ad-hoc Excel autofilters, and deleting records. Human decision fatigue sets in after only 200 rows, leading to false positives and accidental deletion of valuable accounts.
Downstream API & Credit Waste
Uploading unfiltered CSVs directly into downstream enrichment platforms (such as Clay, ZoomInfo, or email verification tools) burns credits on contacts you will never reach. At an average of $0.15–$0.40 per enrichment lookup, running a dirty list wastes hundreds of dollars in under five minutes.
