7OH+ Emails

Is there anyone here that knows how to get this company to stop sending emails?

I added 2 of my emails (Gmail) to their list for emails. I have never seen a more annoying company and no matter how many times I unsubscribe, they continue sending mails.

3-6 per day and I cannot get them to stop.

I can't figure out how to block them nor a way to report them through Gmail. Does anyone know what to do to make sure I never see another mail from them?

I don't know why they think annoying people this much helps their business.
