Best match

With best match attribution, only a single target treatment instance receives full credit for a response; and any other matching treatment instances receive zero credit. When multiple treatment instances match for a response, Unica Campaign chooses the treatment instance with the most recent contact date as the best match. If there are multiple treatment instances with the same contact date and time, Unica Campaign credits one of them arbitrarily.

Note: In the case of multiple treatment instances with the same contact date and time, the same instance will be credited each time, but you should not expect Unica Campaign to select a specific treatment instance.
