I have used Email Grabber for many years but lately it seems to not work very well on job boards I try to crawl.
So I went searching for a replacement and found an online version that seems to do the trick.
It’s called Online Email Extractor. You simply enter a URL on its form, press the Extract Email button and it will email you a .csv file when its done. It takes a while depending on the number of emails you set as a limit. You get 50 emails for free then just pay a penny per email after that.
I ran it on collegegrad.com and got the following results emailed to me. You can even add multiple sites to the query to help save time. Use it to crawl your competitor job boards and compile a list of employer leads.
