The following example verifies a set of e-mail addresses all at the once, using EmailVerify.NET batch verification engine.

        Dim verifier = New EmailBatchVerifier()

        ' Set up some addresses to check

        Dim addresses = New List(Of VerificationData)()

        addresses.Add(New VerificationData("me@example.com", VerificationLevel.Disposable))
        addresses.Add(New VerificationData("you@example.com", VerificationLevel.CatchAll))

        ' Start the batch processing asynchronously

        Dim verificationResult As IAsyncResult = verifier.BeginBatchVerify(addresses)

        ' Use the standard thread pool to wait for the batch completion in parallel

        ThreadPool.QueueUserWorkItem(Function(ByVal target As Object) Do
            verifier.EndBatchVerify(verificationResult)
            
            ' At this point the whole batch is completed
            
            For Each address In addresses
                Console.WriteLine("Address: {0} -> {1}", address.EmailAddress, address.Status)
