Question about starting up again

I played clash for a long time and then a buddy of mine took over my account. My daughters recently started playing on their I pads, so I thought I’d download the app again and start over. When I try using my email to log in with supercell ID, it never sends a verification code to my email. Not allowing me to sign in at all. How can this be fixed? And would it be possible to switch over my daughter’s account to mine?
