Your tanooki profile is unique to you so using a personal email address as your primary account email is ideal as you will have access to it even if you change companies, or work across multiple companies as a freelancer.

Email verification
When you sign up, we need to ensure it is you by sending a verification email. If you’ve used your personal email address you should get this immediately (it’s always worth checking your junk/spam folder). If you used a work email address, the verification might get stuck in a corporate IT holding pen for some time. If the email still hasn’t landed, please speak to your IT administrator as only they have the keys to unblock.
