to sword 19 -- I use GMAIL (Google Mail) -- you can chose it as your default and copy all the information now in Mail to GMAIL (that will not erase what is in Mail.). You can also set it so any other email addresses you have, be it gmail or other, go to the same inbox, etc. So although all my emails, old and new, appear also in "Mail," I do not access them in Mail at all. You can authorize Gmail to access your Apple contacts and this way you don't need to duplicate entries, or you can enter them in Google Contacts, too. Your choice. As you become more proficient in using Gmail you will find out that it offers many more features that Mail does not. Its "search" function is far superior than Mail's.
