For charities and non‑profits, supporter data is the backbone of effective legacy giving. Yet while nearly half of organisations want to use insights to improve services, more than half are held back by CRM challenges.
Poor‑quality data can have serious consequences - from losing touch with potential legacy supporters to missing opportunities for deeper engagement, and even risking compliance issues.
Our data validation and cleansing tools give you confidence in your records, helping you communicate effectively, strengthen relationships, and grow your legacy giving programmes when using tools outside of FirstClass, such as CRM, Marketing, and Mailing.
