Lately on Steem, there have been many attempts on abusing these user registration faucet. That's probably why they are now way too stricter on approving an account.

To increase your chances of being verified and if you don't mind sharing a little bit of your personal data, you can associate your email-add and phone number to any of your social sites like FB/Twitter/IG.

Yes you can use any emails it dependa upon you but the email you are using you should keep its password and backup safe because it very important to keep your steemit and musing safe in your mail box so it is worldwide and you can use your key anywhere.
