the best auto-responder

Hi

I would like to set up an autoresponder on my site.

I have looked here and was wondering whether they are any good: http://www.getresponse.com

What I am looking for is:

1. to be able to pre-write messages and choose when they will be sent

2. I run a vbulletin community, and I would ideally like to be able to add my forum members into my list.

3. to attach pdfs to these messages.


Does anyone know of a good solution

Thanks

Zach

Thats the one i am more attracted to. I don't know whether its good or not though because I have never done this before.
