You can make a new class called 'Mail'. If you make a class, you don't have to type all of the code again if you want to send more than 1 email.

Imports System.Net.Mail
Public NotInheritable Class Mail
    Public Property subject As String
    Public Property body As String
    Public Property receiver As String

    Public Sub send()
        Try
            Dim smtpServer As New SmtpClient()
            Dim mail As New MailMessage()
            smtpServer.UseDefaultCredentials = False
            smtpServer.Credentials = New Net.NetworkCredential("[e-mail]", "password"))
            smtpServer.Port = 587
            smtpServer.EnableSsl = True
            smtpServer.Host = "smtp.gmail.com"

            mail = New MailMessage()
            mail.From = New MailAddress("[e-mail]")
            mail.To.Add(receiver)
            mail.Subject = subject
            mail.Body = body
            smtpServer.Send(mail)
        Catch ex As Exception
            MsgBox(ex.Message & vbNewLine & ex.StackTrace)
        End Try

    End Sub
End Class

And then you can make a new object in your code where and when you want to send the email:

Dim email as new Mail
email.receiver = "[e-mail]"
email.subject = "Subject"
email.body = "Message"
email.send()

Private Smtp_Server As New SmtpClient()

Private Sub email_send_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles email_send.Click
Try

Dim e_mail As New MailMessage()
Smtp_Server.Credentials = New Net.NetworkCredential("[e-mail]", "password")
Smtp_Server.Port = 25
Smtp_Server.Host = "mail.v-basic.net"
e_mail = New MailMessage()
e_mail.From = New MailAddress(from_txt.Text)
e_mail.To.Add(to_txt.Text)
e_mail.Subject = "VB.NET Email Sending"
e_mail.Body = text_txt.Text
Smtp_Server.Send(e_mail)
