Verification emails are sent as soon as you sign up for an account. You should receive it within a few minutes to the email you signed up with.
If you don't see it:
Confirm you signed up with the correct email. The email will be shown on the verification page. If you signed up with the wrong email, simply click "back" and sign up again with the correct email.
Check your spam folder for the verification email.
Some email services like Gmail will route the email to a separate tab like "promotions" or "newsletters". Check theses other tabs.
Click "resend email" on the verification to try again.
