How to add item to listbox and then send email.

Good day guys, I'm a semi-intermediate here in c#. Actually, the said topic name it won't work with my codes implemented, i need some help on how to improve my timer tick procedure code as shown what I've tried below.

private void timer1_Tick(object sender, EventArgs e)
{
statmessage();
int i = listBox1.SelectedItems.Count + 1;
do
{
var exp = (EItem)listBox1.Items[i];
var timeVisible = DateTime.Now - exp.Added;
if (timeVisible.TotalSeconds > 5)
if (counter == 100)
{
SendMessage();
counter = counter - 1;
++i;
}
else if (counter <= 0)
{
statmessage();
}
} while (i < -1);
}
}
}

Your feedback is highly appreciated and will help to improve the said concern, Thank you very much.

Then avoid using timer, fire the email function on your add buttonand also set a flag of zero and one that you can know the email is sent or not
