All-Community:  These guys work in conjunction with Yes-Mail.  They pay you for receiving e-mails.  And they send a decent amount of them too.  Not a bad one.

dollars4mail: A new get paid for receiving e-mail program and they give you $10 just for signing up.  It has 6 referral levels.  5 cents/email for yourself and the line runs down .03/.03/.01/.01/.02  How it basically works is that they figure we all get junk mail anyway so why not get paid for it.  They give you a free e-mail account and send you an e-mail everyday with 5 links in the message.  Click on them and get paid.  Couldn't be easier.

HTMail:  You get paid $.08/e-mail and $.02/ referral e-mail(1 level).  A cool part is that you get paid double if you visit the site in the e-mail.  Easy to join and very easy to receive e-mails.  Hey, it wouldn't hurt to join.

iCameo:  Get paid to fill out surveys and earn $1/minute doing it.  Plus there are 2 referral levels below you.  Very easy to sign up and very easy to fill out surveys.  Check it out.

Iwin:  These guys are great!  You can play many different games here and you earn icoins with each win.  Plus the prizes are really good and I know for a fact that they pay because I have received stuff from them.  Check it out and please use prodigy1018@yahoo.com as your referral name when you sign up.  

MySurvey:  This one pays you for completing surveys.  Plus you get a $2 bill mailed to you for signing up and for any referrals you sign up.  Cool eh!

SendmoreInfo:  This one works but is kind of sucky.  They pay you for receiving e-mails.  No need to respond to them, so it is kind of cool.  They pay 5 cents per e-mail received and 2 cents for e-mails received by your referrals.

Total E-mail:  Basically all you do is sign up and they send you some e-mails once in a while and you get paid for it.  not sure of the rates just yet but they have 4 referral levels so it's not too bad.  Plus you can earn points by filling out surveys and playing games one their site.  Sounds good.

YoYoMail:  Not to much known about pay rates, but you get paid for reading e-mail and for 1 level of referrals.  An e-mail account is set up for you and you get 2 megs of space.  So, you get another free e-mail account and get paid for some e-mail that is sent there.  Easy.
