I have a list of several emails (100s) and I'm on the prowl for a tool that will find the first name, last name, and any other relevant information related to that particular email. However, I don't want to search on each email one at a time. I'd prefer to provide a spreadsheet of all the emails and then have the tool find all the contact information related to each email. Any suggestions?
In the past, I have been very impressed with Tower Data. Because I am a software developer, I have only ever used it in the API context (write a script and pay for the limited API usage). There may be a UI for people who'd like to do it manually... not entirely sure about that.
@Trevor Ewen Thanks!
Searchbug.com has a good, very inexpensive reverse email append you might consider.
@Jeff Mason - the above tool can also be used to batch email search.
