What's the fastest way to gather data on company url? (personalised cold emails)

So I do cold emails and I would like to use chatgpt to write a personalized first line based on the information/description I have about the site.

Currently, chatgpt will either use whatever it has on its database or guesses based on the url, what the company does.
However, on Google Sheets, when I hover on the website url, it provides a website summary + provides meta descriptions.
What is the best way to be able to capture the latest data about the company website?
