Reverse Appending

Leverage email addresses to uncover names and postal addresses for B2B marketing. By using your existing email database, we can enrich your records with additional details about the individuals behind those emails—enabling more precise segmentation, targeting, and multi-channel outreach. Reverse Append is ideal for marketers whose databases contain only email addresses. It works by matching your email list with the Smart Business contact database, which holds over 900 million records, including names and physical addresses. When a match is found, we provide a file containing the corresponding name and valid postal address linked to each email.

CASS Certified Addresses

CASS-Certified Address Accuracy ur Reverse Append process leverages a CASS-certified database along with proprietary address standardization technology to deliver only the most accurate and high-quality addresses. Built on industry-leading matching algorithms, our system carefully evaluates every component of an address—including suffixes, apartment or suite numbers, PO boxes, rural routes, and city names—to ensure compliance with USPS standards. Updated monthly, our platform also incorporates ZIP+4 data, guaranteeing that every address provided is valid and fully deliverable.

Lower Postal Costs

Standardizing addresses helps reduce your mailing costs by ensuring they meet USPS formatting and content guidelines. Through Reverse Append, we fill in missing address details, correct spelling errors, standardize city names and state abbreviations, and format the data to align with USPS requirements. The final output is a clean, accurate, and fully deliverable mailing database, ready for use.
