Get
Response
Free
autoresponder service that offers unlimited autoresponders,
no maximum mail length, automatic multiple messages sent
over a period of time and much more. It's all free, but
you'll have to put up with a small advertising message at
the top of every message you send out. This can be removed
for a fee.

Free autoresponder service; offers unlimited hits,
customizable messages that can be changed online and
password-protected access to stats information. Great small

Responders.net
Free autoresponder and form for collecting information
on your site. You can set up an information request form
very easily, then specify what message you would like to
send automatically to people who fill in the form.

SendFree
Autoresponder service with an interesting twist: SendFree
also acts like an advertising exchange service. How it
works: you sign up for a SendFree account and set up your
autoresponder service. At the top of every automatic reply
your autoresponder sends out is a short text advertisement.
Half of these are for other members' sites. The other half
are reserved for SendFree's advertisers. In turn, your
advertisement will appear at the top of messages sent out by
other members.
