The challenge was it was slow and messy.
Yesterday I discovered I can create my own custom search engine
for any website, including Manta.
Super easy and fast.
Just need a Google account.
You still need to extract emails out of text.
In the screnshare video I take you through from finding the custom search engine page, creating it for manta.com, what to type into the search bar, where to paste text into the email extractor, how to get into your custom search engine at a later date. all in a couple of minutes.
Let me know if you have any questions.
