MailAddress fromEmail = new MailAddress("mailaccount@gmail.com", "Name");
MailAddress toEmail = new MailAddress("mailaccount@gmail.com", "Name");
AlternateView alternateView = AlternateView.CreateAlternateViewFromString(htmlString, null, "image/jpg");
LinkedResource linkedResource = new LinkedResource(@"routeofmyimage");
alternateView.ContentId = "logo";
alternateView.LinkedResources.Add(linkedResource);
MailMessage message = new MailMessage()

From = fromEmail,
Subject = "Subject",
IsBodyHtml = true,
