Once data is appended, the validation of accuracy and relevance automatically keeps insights useful. For example, confirmation of the correctness of an email address or telephone number ensures outreach effort is focused on the right people and is not wasted on wrong or nonexistent targets. This involves verification of information against trusted sources for data that is either outdated or wrong, making records as accurate as possible in agencies where clear communications matter and such distinction makes all the difference between a successful campaign and a missed opportunity.
