AI for discovery similar terms

Hi guys, how are you? I hope you are well!

I’d like to go inside the AI contexto, but I’m newer about it.

Context:

1- I have a list of valid domains for emails (gmail, hotmail…)

2- I have a list of invalid domians confirmed from ESPs (not exist)

3- I’ll have every day a list of new domains to check.

If match with set 1 or 2, the domain will be removed from table (join context) - were validated

With the table result, I’d like to use the AI to watch from invalids domain to finde something “seams / Like” a invalid domaid to mark it to validadtion.

How can I use AI for that?

Example file with data attached.
