You probably know this very well. You log into your email account, check out if there is anything new and you see at least a couple of new messages. Perhaps on or two of them will be from somebody you know, while the rest are advertisement. Unless, of course, you have a paid email account, there will always be stuff like that. A majority of email users will get rid of the advertisements straight away because they simply do not need them. They are not interested in new sports equipment, cosmetics or payday lenders. You might wonder why the companies are still selling these advertisements if hardly anybody reads them. Well, the truth is that promotion campaigns can take a while to work. You might see the ad today, throw it away, see it tomorrow again, and so on. But in this process, you remember the name and the logo of the business.

Again, a majority of us will choose the service of some well-known, well-promoted banks and companies. They will seem more reliable and easily available, so there is nothing extraordinary about it.
