Frequently Asked Questions
What happens during Data Appending Services engagement?
You upload or connect your file, we match it against verified master databases, and returned columns are clearly separated so you approve exactly which fields overwrite your CRM.
Will appending break my CRM workflows?
No. Output arrives ETL-safe with stable IDs and column mapping, and we flag rather than delete duplicates so your team controls merge decisions.
How is match quality measured?
Every delivery ships with a match-rate report showing confidence tiers per field, and appended emails carry the same sub-1.4% bounce guarantee as our list products.
Do you handle consumer records too?
Our core strength is B2B enrichment, though opted-in consumer contact appends are available for eligible use cases after compliance review.
