Disable Email notificiations

Hi, I’ve installed your plugin on one of my client websites. And she got an email with this message: https://prnt.sc/tzekey

She does not want to receive email notifications about spammers, where can I turn off those notifications? I could not find it anywhere in the plugin

I’ve found only this, but I suppose that is not what I need: https://prnt.sc/tzen9y

So, I need to disable all email notifications from this plugin.

Thank you in advance
