        Dim email = "example@example.com"
        Dim mbv As New MailboxValidator.SingleValidation(apikey)

        Dim mytask = mbv.ValidateEmailAsync(email) ' async API Call
        Dim myobj = mytask.Result

        Console.WriteLine(JsonConvert.SerializeObject(myobj, Formatting.Indented)) ' to pretty-print the JSON

        Console.WriteLine("email_address:" & myobj("email_address").ToString)
        Console.WriteLine("base_email_address:" & myobj("base_email_address").ToString)
        Console.WriteLine("domain:" & myobj("domain").ToString)

Check if an email is from a disposable email provider#

You can validate whether an email address is disposable email address or not as below:

Imports Newtonsoft.Json

Module Program
    Sub Main(args As String())
        Dim apikey = "PASTE_YOUR_API_KEY_HERE"
        Dim email = "example@example.com"
        Dim mbv As New MailboxValidator.SingleValidation(apikey)

        Dim mytask = mbv.DisposableEmailAsync(email) ' async API Call
        Dim myobj = mytask.Result

        Console.WriteLine(JsonConvert.SerializeObject(myobj, Formatting.Indented)) ' to pretty-print the JSON

        Console.WriteLine("email_address:" & myobj("email_address").ToString)
        Console.WriteLine("is_disposable:" & myobj("is_disposable").ToString)
        Console.WriteLine("credits_available:" & myobj("credits_available").ToString)
    End Sub
End Module

Check if an email is from a free email provider#

You can validate whether an email address is free email address or not as below:

Imports Newtonsoft.Json

        Dim email = "example@example.com"
        Dim mbv As New MailboxValidator.SingleValidation(apikey)

        Dim mytask = mbv.FreeEmailAsync(email) ' async API Call
        Dim myobj = mytask.Result

        Console.WriteLine(JsonConvert.SerializeObject(myobj, Formatting.Indented)) ' to pretty-print the JSON

        Console.WriteLine("email_address:" & myobj("email_address").ToString)
        Console.WriteLine("is_free:" & myobj("is_free").ToString)
