Choosing Email TLD

Hi all,

I want to register a .quest domain for my mountaineering apparel company. However, I came across The Spamhaus Project which states that the quest TLD is the “8th-worst” in terms of email spam received from said domain.

My question is: does this mean emails from my company are more likely to be automatically categorized as spam by things like Gmail (or) is this site simply making a factual statement that “a lot of spam comes from these domains”
