4. Email Addresses
If you are going to advertise online, you must have more than one email address. Otherwise your main email address will get filled up with heaps of junk you don't want. I have one free hotmail address for each purpose: Personal, Subscribing to Ezines, Submitting to FFAs/Safelists, One for each business. I then forward them all to Incredimail so I can read them all without signing in and out all the time.
Incredimail - free, great organiser, auto-mail-connect
Eprompter - free, auto-mail-connect, even works with free yahoo accounts.
EmailAddresses - lists free email addresses
Having different email handlers is good, as you can open them all at the same time. My favourites are Yahoo, Hotmail, FastMail.fm and zwallet.com.
