Your code seems fine,probably the HTML viewer in the mail is not able to support the iframe tag. Use object tag instead.

My vote of 3: Never embed object tags, applets, active-x controls, JavaScript or iFrames in an email - it's far too often malicious content and if it isn't you should avoid being classed as malicious. Please see my solution.

Edit: Also, that solution is unlikely to work across email clients - it's talking about IE6 & 7! Very outdated... A lot of people now use web mail clients such as gmail, which I would hope blocks all types of embedded content such as this - it certainly blocks a lot of embedded files/images which is good - protects the user from malicious content. Furthermore, you would have to start catering for all the browsers and email clients in your one email - much better to simplify the problem and make it friendlier to users by sending description, an image and the url to go to if they trust your email.

Absolutely agree with you, Ed. My answer provides the method that youtube implements via their share feature.

Hi there,

If you are viewing the email in any decent email client then it will block the use of iFrames unless the suer specifically allows it. Sending HTML emails (especially ones with JavaScript and iFrames) is a very bad idea. 2 reasons: 1) It's unfriendly to users and a common thing for phishing scams or viruses to do. 2) Because of 1, most email clients block JavaScript and iFrames etc so your email will almost never display properly.

Assuming you are trying to publicise your video or whatever: Far better would be to send a snapshot (single frame image) of the webpage or video, a description of it and a text link (NOT an html clickable link) to the page/video. This is friendlier to users, looks less malicious and will display properly across mail clients.

Hope this helps,
Ed

Your answer is that the use of an iframe in an email message is not well supported.
See this[^] as a reference.

This is also not the correct way to embed a youtube video in email. If you go to youtube and share a video via email with yourself you can inspect the html content of that email to discover how you should embed the video properly.

A static-clickable image that will redirect the user back to youtube.

HTML

<a href="http://www.youtube.com/watch?v=Bk_6r-b3kqU&feature=em-share_video_user">
   style="text-decoration:none;display:block" 
   class="nonplayable" 
   target="_blank">
   <img src="http://i3.ytimg.com/vi/Bk_6r-b3kqU/mqdefault.jpg" height="274" width="498">
</img></a>

A playable video(requires flash player)

HTML

<embed width="640" height="385" base="https://www.youtube.com/v/" wmode="opaque" id="swfContainer0" type="application/x-shockwave-flash" src="https://www.youtube.com/v/Bk_6r-b3kqU?border=0&autoplay=1&client=ytapi-google-gmail&version=3&start=0">
</embed>
