Activation key not getting in my email

I’m not getting my activation key on my email.
I’m self hosting n8n on my windows machine.
Email id I’ve used, I think I’ve used it earlier also for n8n.
after I did the setup, I’m not getting activation key on email.

need help

Could be that the signal to the server is not allowed outside your network this usually only happens on strict company networks though. So would not expect this to be the issue.

Did the UI confirm the email would be sent?
