Regional infrastructure and sender reputation testing

Because KingHost's footprint is almost exclusively concentrated within Brazil and the .com.br space, it is a secondary concern for global sender testing but potentially significant for anyone managing delivery to Brazilian audiences. Senders running campaigns targeted at Brazil, or managing multi-region reputation strategies, should treat KingHost's infrastructure separately from globally distributed ESPs, since regional sending practices and list quality can diverge substantially by geography and provider type.
