  • Initialize (email As String, Module As Object, EventName As String) As String

'Example: Do you want check if email: [email protected] is valid
Dim verify_email As checkemail
verify_email.Initialize("[email protected]",Me,"check")
.....

'Valore = "01" --> This domain is active and is set up to receive emails normally.
'Valore = "11" --> This domain operates an anonymous, temporary or disposable email service (DEA). It is likely this inbox will only exist for a few minutes or hours.

The service on which the library was based is no longer active (https://api.mailtest.in/v1/).
You can use the following service in a simple way for example https://mailboxlayer.com/ or https://verifalia.com/email-verification-api.
