I get it, you automate a lot of your job - that is the efficient way to spam but try to put into your automation a blacklist. Blacklist emailing anyone at a @google.com domain, black list emailing anyone with the name John Mueller, Gary Illyes or anyone who works on search at Google or Bing - LinkedIn is a good resource for that.
We've seen countless examples of Googlers saying thank you for sending me your link list or your hidden underground directories of links.
Here is another one from Gary Illyes from Google:
Well this is awkward. It's been pointed out to me that that was not a spam report, but an offer to buy links from Jon. I'm sorry, i guess? ¯\_(ツ)_/¯ https://t.co/wordF6vKaI

I just don't get it - if you want to spam, you should build into your spam techniques ways to stay away from the people in the companies that go after spammers.
