How do I stop emails? I do not want to use this service because it is pushing AI.

I keep getting emails even after unsubscribing.
I just got an email about the AI service. Which is the primary reason why I opted not to use this app and move to another.
I do not want any kind of AI slop being trained on my work and I do not want to keep getting emails from a company that is actively stealing people’s data to train their algorithms without consent.
I don’t care if it says you can turn off the collection.
Google and other tech companies have already proved those are an absolute lie and they continue to collect data anyway.
How do I stop this scam from sending me unwanted emails?
