So long as your user community has/does none of the following 'online',
nor wants info by email:
brokerage and bank accounts, credit card, insurance policy, utility
bill, frequent-flyer membership, travel 'deal' alerts, auto rental
bargains, pension .... customer service for those and more....
Basically anyone who sends you money, wants paid, or is trying to do you
a favor you've actually asked for....
..just to ID those that I personally rely on that might need
whitelisting [1]. And not just for sender verifiction reasons...
MOST of these are not onpassing 'sensitive' information. Rather, they
are just a 'heads up' note that something is awaiting attention and one
needs to log-in via a secure website and view the 'real' meassage there.
Waste of time to slam [ the | any ] ISP when it is more often the
originating agency that you actually disagree with.

[1] If you CAN reliably WL them. That's not a certainty.
American Express for example can NEITHER seem to compose a message that
will pass muster NOR consistently send from the same servers so as to
match a WL.
