I am startup of online and offline marketing company and I am lacking idea on collecting database for marketing purpose.
Yes,a database or client base is very important for a business, i faced this problem too, theres a company digiproteam who can help you out with this_ they provide client bases to other business, i have been using their service for about u months now and they are exvellent.
I've been doing a lot of research on this topic myself, lately. Every eComm podcast talks about building you mailing list.
I'm currently in the process of starting a blog to start capturing some interest. My thought is that this would be a good way to both build a list of email addresses, market my companies and hopefully sell some adds along the way.
The trouble with blogs is that each post must be well thought out in order to maintain the user base.
