Prevent Contact/Account duplicates

Hello

I would like a simple (no code) and quite intuitive way to avoid duplicates on Contacts and Accounts.

For Contacts, ideally, when the user creates a new one with the same email address and saves, a pop up is displayed afterwards.
(I don't see a way for this warning to happen during the creation of the contact).

For Accounts, I would like to have a pop up after saving if the name is the same.

If you have any best practices or good ideas, don't hesitate,

Thank you.
