Param-spam-pam

At e-xecutive.ru there are often mixed materials. Today I read an article about spam as a marketing tool. Here are the main points:

- no one ordered spam. But, for example, radio advertisements are also played without asking listeners.
- Spam is often a hoax. But, a consumer of regular advertising can also be tricked.
- spam is smothered by spam filters. But, why then not the ability to filter ads on TV.
- spam leads in terms of price / number of contacts.

As a conclusion: spam marketing tool, with its pros and cons.

The discussion all boiled down to three aspects: illegal, unethical and damaging the image of the company. The first two points - you can not argue. But about the last.

If you think about it, spam is usually deleted without reading, therefore what the person is talking about, the image does not suffer.
If a person looks through all the letters, then he is unlikely to remember any particular company.
If a person opened the letter and read, it means he is involved - there seems to be no harm to the image either.

Rather, it is about mailing links to porn sites, and spam letters with services (from cleaning to auto repair)

your thoughts? There are examples of how to say this? .. "non-irritating" spam that works?
