Program was created to the emission of letters the e-mail to the large group of receipts, thanks why one can behind his help realize newsletter. The program installs itself on the external server be internal possessing the suitable software that is the interpreter program of scripts PHP together with the database MySQL. I wrote him particularly for private persons and companies. The decision I took due to several very important elements. The company can have her own server or bought up account, what at the today's requirement of the possession of websites is almost sure. Being supposed such server, will be enough to install the software and one can send letters the e-mail. This gives gigantic savings in relation to the buyout of packets on pages which deal with such type with services. At the emission newsletter the for once on week-days we will save several hundred dollars/euro. Often servers sending a message are treated as senders of the spam. Across this the letter the e-mail can reach to the recipient, but to be acknowledged as the spam and to hit to the folder whose user hardly ever does not check. A second option is the rejection of the letter the e-mail from through the server of taking due to this that the server of the sender happened upon the black list. Very important is, so that the message reach to receptions, due to contained in her the communication, the information or the request. Sending her message from servers of companies offering newsletter becoming to their footer stuck on own information that the e-mail was sent across this system. In case of companies respecting of his clients, this will be not very pleasantly seen. Following is the data privacy, that is addresses the e-mail of clients should have pure and simple which company served to them or else sells goods. Not very reasonable is entrusting of these addresses, and even personal data credited to them to other company in which all the time it will be necessary to check regulations, whether by chance did not enter any changes. In one of companies of the person from her list began to write the e-mail, why receive publicities from other producer with own with data address. It turned out that the service provider testifying the emission newsletter changed regulations, and all data defined in the system passed automatically to third companies within the framework of contracts about the cooperation.
