Ask HN: Categorized List of Email Domains?

I’m wondering if there’s a list of domains by major business category.

For example, Shopify.com and Nike.com being tagged shopping or United and NorwegianAir being travel.

I understand the categories can be fuzzy and it requires a generally high volume of data, but it’d be very helpful to find something along those lines!

Has anyone encountered such a data set?
