Trying to send custom emails with Postal.NET

[Sl1ver]

I am trying to send multiple emails using my own email class but I get an error where it says "element contains the same key!"

So I take it the view for my email gets added everytime but it already exists.I just don't know how to check if it exists or how to readd it.

var viewsPath = Path.GetFullPath(HostingEnvironment.MapPath(@"~/Views/Emails"));
            var engines = new ViewEngineCollection();
            engines.Add(new FileSystemRazorViewEngine(viewsPath));
 
            //Smtp Cliet
            SmtpSection smtpSection = (SmtpSection)ConfigurationManager.GetSection("mailSettings/" + emailSection.ToString());
 
            var client = new SmtpClient(smtpSection.Network.Host, smtpSection.Network.Port)
            {
                Credentials = new NetworkCredential(smtpSection.Network.UserName, smtpSection.Network.Password),
                EnableSsl = false
            };
 
            var emailService = new Postal.EmailService(engines, () => client);
            email.ViewName = emailType.ToString();
 
            emailService.Send(email);

At the top where I add the viewPath is where the issue is. It always works when I run it for the first time but after that it it complains as it obviously already exists.
