Ask HN: Are there any services for collecting emails pre-launch?

Service to collect emails via a form you can embed in a page, and manage said mailing list? Yes. You can find a few mentioned on this page:

FWIW, I chose MailChimp for that, but there are plenty of other choices.

If you want something that goes even further, that is, doing the page, video, and everything, plus email, then the answer is "I'm not sure." Probably there are, but I haven't really looked.

You might find value in something like LaunchRock.com, but I'm not sure they're exactly what you're looking for.

Jameson from LaunchRock here. We're literally days away from doing a full roll out, but hit me up at jameson@launchrock.com, and I'll get you an immediate invite. In order to do video, you'll need to use the widget on a page.

http://launcheffectapp.com - A Wordpress theme for viral launches. Haven't tried it, looks nice though!

Just add a wufoo form:

I think you can redesign parts of the form with some basic html/css, to theme it according to your designs.

Are you talking about something like http://launchrock.com ?
