Hi Ali,

The primary reason for verifying the email is purely functional - people
make mistakes and if they enter their email with a typo, they may lose
access to the account when it's most necessary - e.g. when they forget
their passwords. With banks it's a slightly different story because most
of them will not rely on email for password reset  but rather employ a
risk-based, human-driven process through a call center based on a number
of sensitive information known only by the client and the bank. Websites
where an email is the *only* verifiable bit of information they have
from the user are much more keen to verify that the email is indeed
working and under the control of the user.
