The technology involves sending emails through the interface of email services while mimicking user behavior. Its advantage lies in the fact that the emails are sent on behalf of email services with high reputation. Emails from major email services such as Outlook or GMX, for example, are typically delivered to the inbox folder on other email services such as Gmail, Yahoo, Yandex, MailRu, etc.

The email is sent from the user's own account. Essentially, it's like sending a personal message from your own email, making it appear as if you're personally sending the email to the recipient. Services like webimitation.com carry out full automation of this process on a large scale, simulating the sending of personal emails by thousands of users simultaneously.
