mail collector

Hello! I started a handmade jewelry business in december/january. It's been going great, but most of our sales are coming from Etsy and not our website. I would like to change that and get more sales on our website, get more newsletter subscribers and all-around more activity on the website...

I'm working within the oil and gas industry, and we are a product and service provider in this sector. And a small part of my job is to reach out for potential new customers. And calling the frontdesk and trying to get through to the right person for a meeting proposal is pretty time consuming...

basically i need a soft whom i can collect all members mail from any classified site or any site. can anyone help me to giving this ? btw i am newbie on BHW....
