Gmail does not use blocklists to filter or reject emails, and it is unlikely that they use any of the data from Spamhaus.

Or, somebody will tell me that they’re having Gmail issues, and they’ve plugged their own IP address into an online blocklist lookup tool, and they are sure that any results found (blocklisting issues) must somehow be part of the underlying cause of their deliverability woes. Except, that’s just about never the case. Here’s why.There are a zillion blocklists out there. Speaking specifically just about DNSBLs (IP-based blocking lists), there’s a good 90+ of them. But blocklists are a bit like blogs, in that anybody can publish them
