Bigfoot
Among the services that Bigfoot offers are: A free, lifetime, E-mail address; customized E-mail delivery; E-mail control and functionality and a way to "Just Say No!" to junk E-mail. Bigfoot has recently begun offering new features such as free autoresponders (E-mails that are automatically sent to your visitors in your absense) and reminder services, to remind you of birthdays, appointments, etc. 

ApexMail
Free mail accounts, includes auto-responders, forwading, POP retrieval, address book/contact managment, filter blocking and much more 

Autobots.net
We've had several requests lately for a free autoresponder service. (Autoresponders are automated E-mail services that let you send a custom message on demand to anyone who requests it). Autobots.net is the best such service on Net: it's free of ads and allows you to send up to 10 follow-up messages. Lots of options are available here and a daily activity log will be delivered to your E-mail address. 

Everyone.net
Do you have a Web site? Have you ever wanted to offer a free E-mail service of your own to your site's visitors (just like the big boys like Yahoo and Lycos)? Everyone.net offers such a service: they offer "industrial strength," branded E-mail that you can customize to match your site's appearance. What's more, you can earn revenue with this service (You get half of the ad inventory to run your own banners). 

Hotmail
Owned by Microsoft, Hotmail is the largest free Web-based E-mail provider, with over 40 million registered users. Hotmail offers mail filtering that allows you to direct mail into folders and gives you the ability to check up to four POP accounts at once. They also feature a spell checker and a signature option, as well as the ability to customize the layout. You can add up to 20 recipients per message, as well as send attachments (although this process is cumbersome). You can send attachments using Hotmail if your Web browser supports the attachment of files (such as Netscape Navigator 2.0 or later, Microsoft Internet Explorer 3.02 or later, etc.). No spamming allowed. Annoyingly, when you log out of Hotmail, you're automatically redirected to Microsoft's home page. Another drawback is that Hotmail only gives you 2 megabytes of space, which is less than most free E-mail services offer. 

Yahoo! Mail
A reasonably competent (and quite popular) free service, Yahoo! Mail allows you to access your personal E-mail from any Net-connected computer: in offices, homes, libraries, anywhere. This service offers a number of features and lets you organize mail into folders, search & filter your mail, attach files, create an address book, etc. There's also an autoresponder function that'll reply to your messages when you're away on vacation.
