Ask HN: Should we send an e-mail for registered interest.

Hi,

I'm working on a new startup and have put up a splash page for people to leave their e-mail addresses. We have purposefully not chosen to send them an e-mail when they add their details and instead a message pops up saying thanks and we'll be in touch soon etc.

This is because there isn't a lot to say as yet, it really is very early days and we don't want to a)annoy people with email and b)give any specific details on the product.

Someone who recently registered asked 'why did I not receive an e-mail after registering?' - which got me thinking... do people expect an e-mail when they register and should we maybe send one.

What do you think?
