Currently, Gmail is the final version, and Gmail, which can participate without an invitation, seems to have the same function and capacity (over 2.7 GB) as the current one.

Gmail began on April 1st in Japan time in 2004. It was 1 GB capacity, but at that time the original home Hotmail was 2 MB, the main home Yahoo! It was 4 MB. After this Gmail shock, the mailbox capacity of each mail service continues to expand, until now.
