Can junk mail emit greenhouse gases? Yes, it's not alarmist. According to a recent report by ICF, a foreign research firm, a total of 62 trillion of spam messages were sent worldwide last year, and about 0.3 grams of carbon dioxide emitted by each spam message produced 1.7 million tonnes of carbon dioxide a year. This is equivalent to driving around the Earth 1.6 million times, or 1.5 million U.S. households a year of emissions. This shows that spam is not only a waste of resources, but also affect our living environment.
The report says almost 80% of the energy consumed in spam is from user-deleted spam and searches for legitimate e-mails. And the spam filter itself consumes 16% of the energy consumption associated with spam, and further curbing spammers is the most effective way to reduce carbon dioxide emissions from spam.
However, the high level of spam, the important reason is from the rise of the mail marketing and development process, the original mail marketing with fast, low-cost operation and information transparency by the market and business welcome. Because of breaking the traditional marketing approach, the expansion of object-oriented, so that consumers can more directly understand the usefulness of products.

If you find that mail delivery rate, reading rate is abnormally low, you should monitor the IP address in the main blacklist at any time.
2. Note Points for mail writing

Not that the words themselves have any problems, is not completely useless, but as little as possible, so as not to trigger the garbage filtering algorithm.
(2) Less use of exclamation points, reduce the use of exaggerated colors, especially bold red font. This is a typical spam message commonly used to attract eyeballs. If it is English mail, do not use a lot of words in uppercase.
(3) The message content, title, sender name do not use the obvious fictitious string. For example, some spammers will certainly not tell others real, just write a few letters in the sender's name. Maintenance of garbage filtering algorithm is not stupid, this baffling random string is usually a kind of spam characteristics.
(4) HTML mail code should be concise and reduce the use of pictures. Although HTML messages allow you to beautify your messages with pictures, they should be kept to a minimum as opposed to text. The more pictures you have, the higher the amount of trash you may be playing.

The same effect is achieved by depositing e-mail addresses in the Address book.
