Why do I have so many daily unconfirmed subscribers? I get dozens a day on my newsletter, but I have not idea how these bots are signing up for my newsletter because, according to my analytics, I don't have that many people visiting my website. And my website is the only way I have it configured for someone to signup for my newsletter. For example, I have 30+ unconfirmed dated May 7th, but I only had four people visit my website on May 7th, and none of them signed up for my newsletter. So how are these 30+ people/bots listed in my ConvertKit account under unconfirmed signing up for my newsletter? I am so confused.
