Email verification
Checking whether an email address can actually receive mail, without sending a message to it.

In practice
The steps are syntax, then the domain and its MX records, then a conversation with the receiving server about the mailbox, then flags for disposable, role and catch-all addresses. Some servers will not give a clear answer, so results include unknown.
Verification and sending
This is what ValidReach does: it returns a status and flags for each address, for single checks, files and the API.
