Google Workspace setup
Google Workspace publishes its sending IPs under _spf.google.com, which itself nests several includes — often most of your lookup budget on its own. With Solid SPF, keep include:_spf.google.com in your source record; we resolve it to its current IP ranges and keep them updated as Google changes them.
