What is the point?

Even though my email service provider successfully filters most spam messages, some still manage to get through to my inbox.

However, even though it is irritating to get unsolicited mail, most are offering a product or service that I am able to use. i.e. it exists.

It isn’t often that I get an offer for a product or service that is not available. Turning Point IT Solutions offered me an attractive choice of internet fibre packages, differing in price depending on connection speeds.

Only problem? Fibre is not available where I live.

Surely, if you are going to offer a product to a potential client, you should first determine whether that product is available before offering it?

Or am I missing something?
