How to embed a video in an email

Email clients only render a limited part of HTML. They don't run scripts or iframes, which is what YouTube, TikTok and X embed codes are, and most of them don't play the HTML5 <video> element either.

Support data: Can I email's HTML5 video tests. Even if part of your list reads in Apple Mail, everyone else needs something to click. That's why email platforms' own video features produce a linked image rather than a player. Mailchimp's help center says its video merge tags “generate a thumbnail image of a video player and link it to your video online.”

A clickable video thumbnail is a normal image with a link. It looks like a video, and one click opens the video on YouTube, TikTok or X. It takes four steps.

1. Make the thumbnail image

Copy the video's link and paste it into PostCapture. It builds the image from the post's public data:

• YouTube: the thumbnail with YouTube's red play label, plus the title, views and channel.
• YouTube Shorts: the thumbnail with a “Shorts” label. Set YouTube Shorts format to Portrait, or pick a template like Poster, for the full vertical thumbnail.
• TikTok: the video cover with a TikTok label, plus the caption, creator and stats.
• X: the post text and author, with the video still and a play button.

In the editor, pick a template and a light or dark theme that suits your email. The Auto format fits the image to the card, and on a computer HD quality keeps it sharp on high-resolution screens. Click Download image to save a PNG, or use the copy button to paste it straight into a message.

2. Put the image in your email

Insert it as an inline image in the body of the email, not as an attachment. Many email templates use a content width of about 600 pixels; let the image fill that width so the play label and title stay readable on phones.

3. Link the image to the video

Select the image and add the video's normal share link as its link. The steps for Gmail, Outlook and email platforms are below.

4. Add alt text and send a test

Alt text shows when images are turned off and is read aloud by screen readers. Name the action and the video, for example “Play video: Our 2-minute product tour”. Then send a test to yourself and click the image to check the link.

1. Make the thumbnail image and download it, or copy it.
2. In Gmail, click Compose. Click the Insert photo icon, upload the PNG and choose Inline rather than As attachment. You can also paste a copied image into the message.
3. Click the image to select it, then press Ctrl+K (Cmd+K on a Mac) or click the Insert link icon.
4. Paste the video URL and click OK.
5. Send yourself a test and click the image.

Add a short text link under the image as well, such as “Watch the video”, for readers who have images turned off.

Outlook doesn't run video embed code or play video files inside a message. A linked image works:

1. Open a new email and choose Insert → Pictures to add the PNG to the body, or paste a copied image.
2. Select the image.
3. Choose Insert → Link, or press Ctrl+K (Cmd+K on a Mac).
4. Paste the video URL and confirm.

Menu names differ a little between classic Outlook for Windows, new Outlook, Outlook on the web and Outlook for Mac. If your version won't link an image, put a text link to the video directly under it.

Email marketing platforms put the image in a content block instead of the message body:

1. Add an Image block where the video should go.
2. Upload the PNG.
3. Paste the video URL into the block's link field.
4. Write the alt text.

Some platforms have their own video block too. Mailchimp's Video content block adds a play icon to the thumbnail of a long-form YouTube or Vimeo video. For everything else, including YouTube Shorts, Mailchimp's help says to upload an image instead.

That's where a PostCapture image fits: Shorts, TikTok and X videos, or any video where you want the title and channel in a frame that matches your email's design.

• Say what's behind the click. Put the topic or length next to the image, like “Watch: 2-minute product tour”.
• Put it where it matters. If the video is the point of the email, place it near the top, before long text.
• Don't attach the video file. Gmail limits attachments to 25 MB, and recipients have to download a file before they can watch it.
• Check who can watch. Public and unlisted YouTube videos play for anyone with the link; private videos don't.
• Want motion? Some senders use an animated GIF preview. PostCapture exports still PNG images, so you'd need a separate GIF tool for that.

• The image doesn't play inside the email. It's a still PNG that links to the video.
• PostCapture doesn't host images for your email. Download the PNG and upload it to Gmail, Outlook or your email platform.
• It works with public posts and videos from YouTube, TikTok, X and Bluesky.
• It uses the video's thumbnail, not a frame from a moment you choose. For YouTube you can pick the uploader's thumbnail or one of three frames YouTube captures automatically.
• Every new account starts with 3 free images, one time, with a small PostCapture watermark. Pro ($10/month, or $96/year) removes the watermark and includes 500 images a month.
• Sending video every week? Pro also includes the Screenshot API and the MCP connector, so a script or an AI assistant can make the images from a list of links.
