Answer 2

No, pretty much all email servers will refuse to tell you if an address is valid or not these days since otherwise it would be abused by spammers.

Answer 3

Verification links are the only way

Answer 4

Detect the bounces and remove the addresses that bounce from your list. There is no other way, and the overhead is neglectable.

Answer 5

Send an email to each of them. If you don't get a bounce back then the email is probably valid.
