I'm trying to build a list of local contacts from about 500 businesses. Using Google Places API, I was able to generate numerous phone numbers and addresses.
However, Places doesn't offer email addresses. I assume this is because of spam reasons, but there are offer contact addresses on their websites. If they're willing to put it out there, they are willing to receive emails.
Is there an API where you can pass in either a business name or address, and known contact details, including email addresses are included?
