Address verification (Melissa Data)

Validate, standardize, and enrich every donor address automatically using the Melissa Data integration — postal code correction, deliverability scoring, USPS standardization, and apartment/suite parsing. Critical for direct mail campaigns where bad addresses waste postage and hurt deliverability. Runs at import time, on-demand for individual records, or as a nightly sweep across your entire donor base. Surfaces undeliverable addresses before they cost you money.
