Here is a complete working example of how to attach an EPPlus generated Excel file to an email message as attachment. But you have to use a MemoryStream to attach a file to a message.

//create a new memorystream for the excel file
MemoryStream ms;

//create a new ExcelPackage
using (ExcelPackage package = new ExcelPackage())
{
    //create the WorkSheet
    ExcelWorksheet worksheet = package.Workbook.Worksheets.Add("Sheet 1");

    //add some dummy data, note that row and column indexes start at 1
    Random rnd = new Random();

    for (int i = 1; i <= 3; i++)
    {
        for (int j = 1; j <= 27; j++)
        {
            worksheet.Cells[i, j].Value = rnd.Next(1, 25);
            worksheet.Cells[1, j].Value = DateTime.Now.ToString();
            worksheet.Cells[4, j].Value = "val " + rnd.Next(1, 25);
        }
    }

    //save the excel to the stream
    ms = new MemoryStream(package.GetAsByteArray());
}

//create a new mail message 
using (SmtpClient client = new SmtpClient())
using (MailMessage mail = new MailMessage())
{
    client.Host = "mail.server.com";
    client.Port = 25;
    client.Timeout = 10000;
    client.EnableSsl = false;
    client.DeliveryMethod = SmtpDeliveryMethod.Network;
    client.UseDefaultCredentials = false;
    client.Credentials = new NetworkCredential("UserName", "PassWord");

    mail.From = new MailAddress("fake@falsesender.com", "gbubemi smith");
    mail.To.Add(new MailAddress("fake@falsereciever.com"));
    mail.Subject = "Send excel email attachment c#";
    mail.IsBodyHtml = true;
    mail.Body = "<html><head></head><body>Attached is the Excel sheet.</body></html>";

    //attach the excel file to the message
    mail.Attachments.Add(new Attachment(ms, "ExcelSheet1.xlsx", "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet"));

    //send the mail
    try
    {
        client.Send(mail);
    }
    catch (Exception ex)
    {
        //handle error
    }
}

//cleanup the memorystream
ms.Dispose();
