Question

Why when i send html email it looks like:

but initial page is:

Here is code:

MailMessage message = new MailMessage();
                message.IsBodyHtml = true;
                message.Subject = subject;
                message.Body = body;

                foreach (MailAddress recipient in recipients)
                {
                    message.To.Add(recipient);
                }
                if (message.To.Count > 0)
                {
                    SmtpClient smtp = new SmtpClient();
                    smtp.Send(message);
                    return true;
                }

Html file contains css in head.

Answer 1

I assume that the body variable only contains the HTML code, but not the CSS or the images, because both are separate files.
Basically, you need to attach the images to the mail and change the HTML code of the body to point to the correct location. See here for more info and sample code.

Problem:

Some clients rendered my email with no style whatsoever. I first attributed this to the stripping of styles, but I then discovered that the styles were clearly visible in the source code. I subsequently spent a good deal of time attempting to uncover the culprit, testing countless versions of the email. Alas, the problem was right under my nose: the styles weren’t being stripped — the dots (.) preceding their names were. Therefore, “.Feature {}” became “Feature {}”, resulting in a meaningless style definition.

Solution:

I used class selectors, which ensured that each style would begin with a letter instead of a dot. So “.Feature {}” would become “td.Feature {}” or “div.Feature {}” (depending on the application). A somewhat mundane fix, but effective and (again) compliant.
