I was going through my emails and unsubscribing from a bunch of different websites. For the most part, I would receive messages such as “We are sad to see you go!” or “Thank you for your feedback” but with this website, they immediately wanted me to opt back in. I thought this was super strange since I had literally just unsubscribed from the emails, so why would they offer me to opt back in ten seconds after I said I wanted to opt out.
Also going with this, many websites said it could take up to ten days for you to stop receiving their emails but they instantly send you emails when you do sign up.
