A mail alias allows you to move all over the world and keep the same e-mail address, saving on confusion of changing your address with each new job or posting. Prices to other countries will be adjusted to reflect shipping costs. However, having your e-mail address locked to that provider means that if you change organizations for some reason, you lose your address. You could, of course, leave your forwarding address at that ISP's address for two or three months, but then there's always the person who picks up your ad in six months and becomes interested.

Let's say you have a small wholesale firm with several employees responsible for various aspects. First , establish the aliases you'll want to use. Let's say you decide on sales, support, billing, and your own first name. Second , decide whether you want each of those aliases to have their own private account. Some people, obviously, will need a private address, while others won't.
