PayPal update email 'violates own anti-phishing advice'

Not intending to put you on the spot but I think it illustrates some of
the change management issues regardless of the approach you choose.

That might be interesting data, if you can share it.

Until more comprehensive policy becomes available, yes.
In general, using a cousin domain is a bad practice, where the
term
"far" has not been met by your current practice. [...]
Are there any recorded data supporting that assertion?
We experienced an increase in phishing when our marketing department
decided to use cousin domains to promote new products. This left us
dealing with a greater number of complaints from users confused by
what
they had installed. Unfortunately, there is an entire industry
devoted
to taking advantage of user confusion.
