CASS Processing

The CASS process verifies addresses to determine if they are valid. On average, addresses processed through CASS will code 3.96% of a file as non-deliverable / bad addresses.

Deceased Suppression

nSightful can identify deceased customers/prospects by instantly screening your file and removing / flagging the deceased. Sending mail to the recently deceased can be very emotional for family members and is just plain bad for business. Save your customers the emotional distress and your marketing dollars by allowing nSightful to perform a deceased suppression.


nSightful utilizes an exact database provided by the USPS TM that verifies if an address is in fact valid.

Zip+4 Standardization

Recommended by the USPS Zip+4 Standardization (also known as Postal address standardization, address validation, address verification and CASS certification) checks the validity and deliverability of a physical mailing address. An address must be standardized before it can be certified as deliverable (CASS – certified). Standardization will convert an address to the correct format and will add missing information such as a zip code etc. to complete a full mailing address.
