How to Build an Email Contact List as Quickly as Possible
Google provides users with a list of search operators to make finding specific information as easy and quick as possible. Operators are essentially a way to add custom filters to your searches. Here is the full list:

Sometimes you have to use push methods to alert potential customers that you exist. If you’re launching a product, you need people to launch to. This is where operators come in.
If you need a list of 100 email addresses to contact people who may be interested, put the word “email” or “contact” in quotes and specify the site that you are looking to collect information from by typing “site:” followed by the site’s address.

“What if I don’t know which sites to target,” you might ask. If you have one example of a site that matches what you are trying to find, use the “related:” operator followed by the site’s address to find more like it.
