Hey! I set up Porkbun, Microsoft 365, and Smartlead (as per the training). Everything was working well, and after 2 days of warming up, I received the following message in Smartlead (see attached file). I tried to generate the Intelli-Unblock Code, but I never received it. I noticed that I didn't receive any emails yesterday, so I tried to send an email manually, and I received the following message: "Your email couldn't be forwarded from x@growthinc.com to another email address. x@growthinc.com. Your message wasn't delivered because the recipient's email provider rejected it." This is my first experience with cold emailing, and I'm not sure what to do or what's that mean. Thanks!
