How many people do you think click on a link in a HTML signature?
i.e. you might think it's a good idea, but how likely are you to achieve your actual aim?
It's tough to say. Essentially the company furnish us with a choice of various banners/click-throughs that can be used, each being focused on a different area/opportunity. The idea would be to anticipate the customer's (personal contacts/referrals) perceived needs/motivators and select accordingly - eg. for someone with young children I may include a banner linking to further information about the Junior ISA product, for someone older and getting towards retirement I may include a link to Retirement Planning alternatives to a Pension.
In theory this may stimulate some interest, but I take your point.
Even aside from this there is the professionalism and perception point of a good-looking signature I feel.
