By creating one account Gmail, η Google σας διαθέτει δύο διευθύνσεις ηλεκτρονικού ταχυδρομείου. Η μία χρησιμοποιεί το κανονικό domain and is @gmail.com while the second address is under another domain: @googlemail.com.
This means that if your Gmail email address is firstname.lastname@example.org, all emails sent to email@example.com will be sent to firstname.lastname@example.org inbox .
Two in "price” of the one.
How can you use the second address?
You can take advantage of both domains, for less spam in your email inbox.
For example, the address @googlemail.com can only be given to your close contacts. You can use the email that uses gmail.com as a domain publicly (put it in blog you, for example).
You can then set a filter in Google's email service that will redirect all messages from @ googlemail.com to a special folder. So you will never lose important email from your close friends.
