The concept of the newsletter is very similar to that of the FEED even if it is easier to intuition.
You agree to subscribe to a site's newsletter by entering your email and at this time any updates or important news will be sent to you by an e-mail.
Therefore, it is not necessary to install or use extra services such as feed readers.
If users of a site can be a great comfort and utility, even for the webmasters they want to earn is very useful.
In order to monetize a newsletter, you will inevitably receive promotional emails from time to time by placing banner ads (PAY PER CLICK or PAY PER IMPRESSION).
You will ask, but do you agree?
GetMyRefs responds by making a new question: "According to you, why then would there be so many sites that ask you to enter the email to view the content of the site?"
Evidently the mechanism works.
Let's give an example:
"A webmaster has a thousand emails from subscribers to send updates or information.
Each member sends 4 mails a week with a Pay Per Impression banner (on which he earns € 2.00 per thousand views).
Having 1000 receivers that open the email every time they send an update has a $ 2.00 gain.
We said he sent him four times a week, so he earns € 8.00 a week.
In a month there are 4 to 5 weeks so the webmaster (only with a newsletter and with only one banner in each mail!) Can monetize about 40.00 €. "
