The campaign to stop AOL charging to guarantee delivery of emails is growing with more than 500 groups and almost 37,000 people signing up.
The opposition, organised by the Electronic Frontier Foundation, launched in early March with 1,500 individuals and 50 groups.
AOL and Yahoo! announced in early February that they would charge businesses a small fee for guaranteeing delivery of email. Free emails will still be allowed, but will have to jump through various spam filters - the paid-for mail will head straight to your inbox.
AOL insists the move will help stop spam. It will start testing the service later this month. ®
