I have a classic Google Site w/o a G Suite subscription. Last week, I conducted a blacklist check on the site domain name and found that the site IP address is on Spamhaus ZEN blacklist. Spamhaus wants Google to contact them to have the IP address removed from their list. It appears that this IP address is shared by thousands of other sites. I have a business email address which shares the domain name which is hosted by Zoho.com. Will having the site IP address listed on Spamhaus negatively affect email campaigns? I would like to discuss this issue with Google, however, I don't have access to their support. Thanks.
