If you are targeting Polish customers or testing Eastern European market reach, Zenbox appears frequently enough in the .pl namespace to warrant inclusion in a regional testing matrix. Because it sits in the long tail of smaller providers rather than the global tier-one services, it may not be represented equally in mainstream reputation lists or DNSBL databases, making real-world testing more valuable than inference from larger-provider behaviour.
