I made a withdrawal from Dnotes vault. The system sends out a confirmation email with a link to click.

The link looks like this:

Confirmation Link: https://dnotesvault.com/users/confirm?cn=xxxxxxxxxxxxxxxxxxxxxxxxx
but actually refers to: https://u1554482.ct.sendgrid.net/

My email client thinks that this is a spam. It is mainly because the link name is different to the one it redirects to.

I wonder if it is intended to be like this?
