Your Marketing Is Only As Good As Your Data.

SmartAppend™ is the data-enhancement division of Datahouse Marketing. After years of helping direct-mail and digital clients, we saw the same problem: beautiful marketing built on bad data. We created SmartAppend™ to give marketers clean, enriched, and reliable customer data they can trust.

Why Clean Data Matters

Clean, accurate customer data is the foundation of every successful campaign. When your lists are outdated or incomplete, you lose money on undeliverable mail, wasted ad impressions, poor targeting, and missed opportunities. SmartAppend™ solves this by transforming messy data into accurate, enriched, and actionable customer intelligence — so every marketing dollar works harder.
