Spammiest brands (and the cleanest)

Brands ranked by their actual folder placement — independent of which ESP they use. Useful for spotting individual senders with deliverability problems (high spam %) or excellent inbox performance. Brands need at least 100 placement observations to qualify (higher than the ESP view's threshold because per-brand placement is noisier at small samples). Top 100 shown.
