Take a look at the body of this e-mail message advising the target that their e-mail account will be deactivated. There are several things to note here. First, the individual is working a list of known good e-mail accounts.

The objective here is to get the unsuspecting target to click on the hyperlink.
The image below reveals that the message comes from a callmeamanda321. This is a bogus email account which is the reason they attempt to steer you from responding to their email via a reply.

The majority of cyber attacks on government and enterprise IT resources come from these types of e-mail attacks, and the inability of the individual to assess the validity of the message content.
