New site collecting emails.

Hi,

I am launching a new business and website next year and am currently developing my site now. I have just recently purchased an old domain.

I am now stuck on what I should do as a place card holder meanwhile while I wait for my site to be ready.

a) Use one of those launching service slash pages that collect emails....'watch this space etc... to get limited invitations etc enter email...'
b) Fill it with content that targets my keywords.
(note that this will change as the sites content will completely change when it switches to the new content).


If I collect emails...which I am kinda incline towards this as it has a more viral effect, should I sign up with a email service like the common big names. They charge per block of users with unlimited emails. My issue with the charges is that I won't be sending out any emails until I launch but I will still have to collect opt in and sign up with them? i understand that some of them are pretty sticky and that you have to have actual proof of opt in (no idea how to get that) and the best way is to sign up with their system to record the opt ins. Sorry I am clueless about this....

Please advice on the email option (which I will plan to collect either way if I chose a or b). Also which do you think is better, A or b?

Thanks.
