I tried a whole bunch of launchers after they were bought, but none were nearly as good as Nova in my opinion. Either buggy or lacking features I have grown accustomed to. I ended up just installing TrackerControl and turning off Nova’s internet access entirely. It doesn’t require any networking for any of my needs, so just disabling its internet entirely was fine.
If they’re using a service to send the emails, like SendGrid or Mailchimp or something, that Unsubscribe survey is actually hosted by the email sending provider, and the more people that mark the email as spam or use the “I never signed up for this” option or similar, the worse it makes the user of the mail sending service look. If they used Sendgrid for example to send a mass email to 10k people, if more than 5% Unsubscribe or mark as spam or use the “I never signed up for this”, the company might get their account locked down by Sendgrid until there’s an investigation as to why they sent spam.
