I want to send multi-part MIME messages with an HTML component plus a plain text component for people whose email clients can't handle HTML. The System.Net.Mail.MailMessage class doesn't appear to support this. How do you do it?
D'oh, this is really simple... but I'll leave the answer here for anyone who, like me, came looking on SO for the answer before Googling... :)

Use AlternateViews, like so:
//create the mail message
var mail = new MailMessage();
//set the addresses
mail.From = new MailAddress("me#mycompany.com");
mail.To.Add("you#yourcompany.com");
//set the content
mail.Subject = "This is an email";
//first we create the Plain Text part
var plainView = AlternateView.CreateAlternateViewFromString("This is my plain text content, viewable by those clients that don't support html", null, "text/plain");
//then we create the Html part
var htmlView = AlternateView.CreateAlternateViewFromString("<b>this is bold text, and viewable by those mail clients that support html</b>", null, "text/html");
mail.AlternateViews.Add(plainView);
mail.AlternateViews.Add(htmlView);
//send the message
var smtp = new SmtpClient("127.0.0.1"); //specify the mail server address
smtp.Send(mail);

I've found this link on how to using Razor Engine for email templates in asp.net and it worked great. But I've tried to have a logo in the email template with an image.
Something like this:
EmailTemplate.cshtml (this by the way is a strongly-type view)
<html>
<body>
<img src="logo.jpg" />
</body>
</html>
and when I try to submit it on email, it seems that the image path was not read, it only rendered an X in the content.
I'm thinking to pass the image path as part of the Model but it seems odd that way. Is there any way to achieve this?
Any help would be much appreciated. Thanks
To see image everywhere you can use these options:
Absolute Url
You can simply use full absolute path of image for example "http://example.com/images/logo.png"
IMO It is the most simple option and recommended for your problem.
Attachment
As mentioned by Mason in comments You can attach image to mail and then put image tag and useContentId of attachment:
//(Thanks to Mason for comment and Thanks to Bartosz Kosarzyck for sample code)
string subject = "Subject";
string body = #"<img src=""$CONTENTID$""/> <br/> Some Content";
MailMessage mail = new MailMessage();
mail.From = new MailAddress("from#example.com");
mail.To.Add(new MailAddress("to#example.com"));
mail.Subject = subject;
mail.Body = body;
mail.Priority = MailPriority.Normal;
string contentID = Guid.NewGuid().ToString().Replace("-", "");
body = body.Replace("$CONTENTID$", "cid:" + contentID);
AlternateView htmlView = AlternateView.CreateAlternateViewFromString(body, null, "text/html");
//path of image or stream
LinkedResource imagelink = new LinkedResource(#"C:\Users\R.Aghaei\Desktop\outlook.png", "image/png");
imagelink.ContentId = contentID;
imagelink.TransferEncoding = System.Net.Mime.TransferEncoding.Base64;
htmlView.LinkedResources.Add(imagelink);
mail.AlternateViews.Add(htmlView);
SmtpClient client = new SmtpClient();
client.Host = "mail.example.com";
client.Credentials = new NetworkCredential("from#example.com", "password");
client.Send(mail);
Data Uri
you can use data uri (data:image/png;base64,....).
Not Recommended because of weak support in most of mail clients, I tested it with Outlook.com(web) and OutlookWebAccess(web) and Office Outlook(Windows) and Outlook(windows 8.1) and unfortunately it worked only on OutlookWebAccess(web).
Im trying to set the mail message body of an html email to a different language im using
MailMessage msg = new MailMessage();
msg.BodyEncoding = Encoder ?????
thanks
Look to this info: http://en.wikipedia.org/wiki/UTF-8
As #SriramSakthivel mention in his comment you can do it:
UTF-8 Encoding support all language what you need!
MailMessage message = new MailMessage()
{
From = new MailAddress("My#MyMail.com", "Test"),
BodyEncoding = Encoding.UTF8,
Body = body,
IsBodyHtml = true,
ReplyTo = new MailAddress("Someone#Test.com"),
SubjectEncoding = Encoding.UTF8
}
The encoding is not about language, but about character set. C# uses UTF16 internally, so if you set your encoding to UTF, you should be able to write any text you want as UTF can express any character of any set. That's what UNICODE is used for.
I'd like to send email by asp.net . I use this code and it is work fine.
mail.From = new MailAddress("mail#gmail.com", "sender", System.Text.Encoding.UTF8);
string to = Session["Umail"].ToString();
mail.To.Add(to);
mail.IsBodyHtml = true;
mail.SubjectEncoding = Encoding.UTF8;
mail.BodyEncoding = Encoding.GetEncoding("utf-8");
mail.Subject = "subject";
mail.Body = "body" ;
SmtpClient smtp = new SmtpClient("Smtp.gmail.Com", 587);
smtp.UseDefaultCredentials = false;
smtp.EnableSsl = true;
smtp.Credentials = new NetworkCredential("mail#gmail.com", "pass"); smtp.Send(mail);
But I'd like a custom and beautiful mail. Like emails that send from facebook, google team and etc. I know that can use html tag in mail.Body but is it good way? What is the best way ?
This is ready to use code snippet which I use for sending email which contains both text content and the content based on a html template:
// first we create a plain text version and set it to the AlternateView
// then we create the HTML version
MailMessage msg = new MailMessage();
msg.From = new MailAddress("from#email", "From Name");
msg.Subject = "Subject";
msg.To.Add("to#email");
msg.BodyEncoding = Encoding.UTF8;
String plainBody = "Body of plain email";
//first we create the text version
AlternateView plainView = AlternateView.CreateAlternateViewFromString(plainBody, Encoding.UTF8, "text/plain");
msg.AlternateViews.Add(plainView);
//now create the HTML version
MailDefinition message = new MailDefinition();
message.BodyFileName = "~/MailTemplates/template1.htm";
message.IsBodyHtml = true;
message.From = "from#email";
message.Subject = "Subject";
//Build replacement collection to replace fields in template1.htm file
ListDictionary replacements = new ListDictionary();
replacements.Add("<%USERNAME%>", "ToUsername");//example of dynamic content for Username
//now create mail message using the mail definition object
//the CreateMailMessage object takes a source control object as the last parameter,
//if the object you are working with is webcontrol then you can just pass "this",
//otherwise create a dummy control as below.
MailMessage msgHtml = message.CreateMailMessage("to#email", replacements, new LiteralControl());
AlternateView htmlView = AlternateView.CreateAlternateViewFromString(msgHtml.Body, Encoding.UTF8, "text/html");
//example of a linked image
LinkedResource imgRes = new LinkedResource(Server.MapPath("~/MailTemplates/images/imgA.jpg"), System.Net.Mime.MediaTypeNames.Image.Jpeg);
imgRes.ContentId = "imgA";
imgRes.ContentType.Name = "imgA.jpg";
imgRes.TransferEncoding = System.Net.Mime.TransferEncoding.Base64;
htmlView.LinkedResources.Add(imgRes);
msg.AlternateViews.Add(htmlView);
//sending prepared email
SmtpClient smtp = new SmtpClient();//It reads the SMPT params from Web.config
smtp.Send(msg);
and these are key parts of the html template:
<p>Username: <%USERNAME%></p>
<img src="cid:imgA"/>
I'd like a custom and beautiful mail.
I know that can use html tag in mail.Body but is it good way? What is
the best way ?
I don't know exactly what is that supposed to mean, but generally, there are two ways to do it. (If we talking about images or sources in email etc..)
You can use LinkedResource class of .NET Framework.
Represents an embedded external resource in an email attachment, such
as an image in an HTML attachment.
Alternatively, and more simply in my opinion, if you want to use some images in your email, put the image in a public location then just reference that location in the HTML of the email.
I am using C#.Net to send out a HTML email which contains embedded images. These emails work fine in Firefox and chrome but the images do not show up in Internet Explorer (IE). I know that the IE settings are not causing the problem since embedded images sent using Blat work just fine. Am I missing some option such as character set which is causing this problem? My code is as follows
MailMessage msg = new MailMessage();
MailAddress from = new MailAddress("Myemail#MyDomain", "My Name");
msg.To.Add("Myemail#MyDomain");
msg.From = from;
msg.Subject = "My subjecct line";
AlternateView htmlView = AlternateView.CreateAlternateViewFromString("This is a sample JPG embedded image<br><img src=\"cid:image1.jpg\">", null, "text/html");
LinkedResource EmbeddedObjects1 = new LinkedResource("PathToImage\\image1.jpg");
EmbeddedObjects1.ContentId = "image1.jpg";
htmlView.LinkedResources.Add(EmbeddedObjects1);
msg.AlternateViews.Add(htmlView);
SmtpClient smtpclient = new SmtpClient("mailhost.domain.com", PortNumber);
smtpclient.Send(msg);
Maybe it helps if you create the LinkedResource with a ContentType combined with Coding Gorilla's idea of a guid as the content-id:
Guid contentId = Guid.NewGuid().ToString();
AlternateView htmlView = AlternateView.CreateAlternateViewFromString(
"This is a sample JPG embedded image<br><img src=\"cid:" + contentId + "\">",
null, "text/html");
ContentType ct = new ContentType(MediaTypeNames.Image.Jpeg);
LinkedResource EmbeddedObjects1 = new LinkedResource("PathToImage\\image1.jpg", ct);
EmbeddedObjects1.ContentId = contentId;
htmlView.LinkedResources.Add(EmbeddedObjects1);
Try adding the following.
msg.IsBodyHtml = true;
Additionally, I usually setup my AlternateView like this.
AlternateView htmlView = AlternateView.CreateAlternateViewFromString(html, new ContentType("text/html"));
Embedded images work by creating dataUri schemes. IE < 8 doesn't support those.
I use a C# code to send some e-mails to different users with mail clients on different platforms: BlackBerry, iPhone, Pc, Mac, etc. Here is the snippet:
Attachment attachment = null;
if (attachNameFile!=null)
{
attachment = new Attachment(attachNameFile, new System.Net.Mime.ContentType(attachMimeType));
}
SmtpClient smtp = new SmtpClient
{
Host = this.smtpServer,
Port = this.smtpPort,
EnableSsl = false,
DeliveryMethod = SmtpDeliveryMethod.Network,
UseDefaultCredentials = false,
Credentials = new NetworkCredential()
};
using (MailMessage message = new MailMessage())
{
message.From = fromAddress;
if (macTo != null) message.To.AddRangeUnique(macTo);
if (macCc!=null) message.CC.AddRangeUnique(macCc);
if (macCcn != null) message.Bcc.AddRangeUnique(macCcn);
message.Subject = subject;
message.Body = sb.ToString();
if (replyTo != null)
message.ReplyTo = new MailAddress(replyTo);
else
message.ReplyTo = fromAddress;
if (attachment!=null)
{
message.Attachments.Add(attachment);
}
smtp.Send(message);
}
Some user told me that the message he or she receives doesn't have the attachment. The attachment is a text (UTF8) file.
After some analysis, I saw that the attachment is shown in the body of the mail and only some mail clients show it as an attachment. It is not a problem for me, but BlackBerry has some problem with this kind of attachments, because it shows only the body and cut off the attachment. But it works in Google, iMail, Thunderbird, etc. etc.
I analysed the source of the message and I saw the ContentTransferEncoding of the attacchment is 8 bit:
Content-Transfer-Encoding: 8bit
Content-Type: text/plain; name=Attachment.2324333.txt
I think I resolve my problem if I set the ContentTransferEncoding property of the object Attachment in C# to Base64 encoding:
Attachment attachment = null;
if (attachNameFile!=null)
{
attachment = new Attachment(attachNameFile, new System.Net.Mime.ContentType(attachMimeType));
attachment.TransferEncoding = System.Net.Mime.TransferEncoding.Base64;
}
Do you think it is a good and working approach? Do I have to set other properties?
Thanks to all
Looking at some of the attachments coming from my BlackBerry, I think you need to add a Content-Disposition header:
Content-Transfer-Encoding: base64
Content-Type: text/plain
Content-Disposition: attachment; filename="myfilename.bin"
See: Sending email with attachments from C#, attachments arrive as Part 1.2 in Thunderbird
Content Disposition was the solution for my problem.
Seems to me you're doing everything right, the other mail clients prove it. Try BASE64, there's a good chance BlackBerry will like it, but you can't be sure until you actually see it :).
