Email Spy от Evan Sangaline

Email Spy is a browser extension that lets you find email addresses for any domain with a single click. This can be very useful when doing marketing and lead-generation research for your business. Even if there's an easy to find contact email or form on a company's website, it is often much more effective to target your email to the correct person.

Features include:


- Works with both Chrome and Firefox.
- Finds email addresses with a single click.
- Supports email templates to prepopulate email drafts.
- Completely free and open source.
