Minecraft why can't I get a confirmation email?

I wanted to create a Minecraft account and you have to have a Mojang account so I wanted to create a week ago, but I did not receive a confirmation email after registration.

Does anyone know why it could be my email is correct and in my spam folder, I've also looked

Just wait until tomorrow otherwise write down the support or try it again

I registered it but a week ago and the support does not answer either
