I really have 3 inter-related questions.
It's common knowledge that if you have a new offering, you should put up a landing page and start acquiring email addresses through xyz channels.
The questions I have are:
1) Is there a time frame after which it would be considered as being too long between the landing page going up and the offering being available (whether its available as a private beta first or publicly available)?
2) Are the ramifications of this time being too long simply people forgetting/losing interest or are are there other negative consequences that are not as obvious?
3) Also,while the people who have signed up are waiting to get access to the offering, are there any best practices for keeping them engaged/keeping your offering top of mind in this pre-release phase?
It seems that simply sending progress updates wouldn't cut it, given everything else people have going on in their lives & how low email open/click through rates are in general.
