There are spams because there are spammers. Why do spammers spam ? Because some people buy their products through their spams. This is why they keep sending spams.

However, their target audience is very small depending on the product they sell.
So they have to send emails to a large group of people in order to reach their
customers.

Many people take pleasure in perusing through the spam folder in their favorite email utility. Of course if they peruse, they will probably eventually go at least one time on a spammer website and maybe buy their product.

Of course if somebody has the skills or is able to employ somebody who has the skills to setup a web application online and send mass advertisements through emails, it will be easier and more profitable for him to actually sell products (any kind of legal products) than trying to steal credit card numbers in order to use them or sell them.

However the kind of products that sell better through semi-solicited email advertising often doesn't want to be seen in the inbox directly, but could potentially be interesting to some users.

Mass email advertisement creates very a heavy network load and R&D loads, for Internet Service Providers (ISP) and Email Providers (EP) because they have to dynamically filter very different types of email with all very different format based on guessed user preferences, which can be quite unefficient and expensive.

If EP, in their registration process would add an option to receive spam (which could be call something like Solicited Advertisement MailS or SAMS) from a customized selection of categories and/or products (while being able to exculde certain comapnies/manufacturer/brand/etc...). They could sell an Email Marketing Service (EMS) without disclosing any single email address of their users by selling advertisements targeting users who chose to accept SAMS and which match the criterias they configured in their registration process (which they can easily change in their account settings under the "Configure my SAMS choices").

It becomes then easier for advertisers (SAMSers) to create more professionaly looking emails because they don't have to take the spam filter into account. The EPs can much more easily validate submitted SAMS by their merchant interface than through the spam filter and easily exclude any inappropriate advertisement email.

Illigit UCE (Unsollicited commercial Emails) can then much more easily filtered by the spam filter, because of the largely reduce need to take the spam filter into account. It is then much more easy to bring the illigite UCE sender to the authorities thereby creating a strong incentive to stop sending illigit UCEs.

The existing legit email marketing solution providers would be untouched by such a change since the audience of their customers is already receiving their solicited advertisements properly.

With such a solution, the end user wins, the Email Provider wins, the advertisers wins, the manufacturer wins, the ISPs wins (by having a reduced network load), the customer wins, the webmasters wins, ....
