Video in email marketing: how to add a video to an email (and what actually works)

Video in email marketing: what actually works?

Video in email marketing works best as a clickable preview, not as a player inside the message: most email clients, including Gmail and Outlook, will not play an embedded video, so you show a thumbnail or a short animated GIF with a play button and link it to the video hosted on a web page. The recipient clicks, the video opens in the browser, and you measure that click like any other link.

TL;DR

• Don't attach the video file and don't count on inline playback. Gmail and Outlook show nothing playable.
• Use a thumbnail with a visible play button, linked to the video on a landing page or video platform. It works in every client that displays images.
• Add motion with a short GIF (a few seconds, kept light) when the first frame alone isn't enough to make people curious.
• Write alt text, a caption and a text link so the email still makes sense with images off and for screen-reader users.
• Measure the click on the video link, then what people do on the page after watching.

Can you embed a video in an email?

Technically yes, practically almost never. HTML5 has a video element, and Apple Mail on Mac, iPhone and iPad can play it. Gmail, Outlook and most webmail services strip it out or ignore it. Because a campaign goes to a mixed audience, a true embed means most of your list sees either a fallback image or an empty space.

That is why "embed video in email" in practice means one of the four methods below.

Why don't Gmail and Outlook play embedded video?

Gmail and Outlook don't play embedded video because they deliberately limit what an email can run. Email clients filter HTML for security and privacy: scripts, embedded players and iframes (the code a video platform gives you to embed a video on a website) are removed or blocked. A YouTube or Vimeo embed code pasted into an email therefore disappears or shows as a broken block.

Three practical consequences:

• "Embed video in email Outlook": in Outlook, insert an image and link it to the video. There is no setting that turns on playback inside the message.
• "Embed video in email Gmail": same answer. Gmail may show a preview of a YouTube link under a personal email, but you can't control it, and it does not apply to designed campaigns.
• Attachments are not a workaround. Video files are heavy, many mail servers refuse large attachments, and the recipient has to download the file before watching it.

Rendering differences between clients go well beyond video. If your layouts change from one inbox to the next, read why your newsletter looks different in every inbox.

How to add a video to an email: the thumbnail and play button method

To add a video to an email that everyone can open, insert a still image of the video with a play button on it and link that image to the page where the video plays. It takes about ten minutes and works in any email editor.

1. Host the video on a page people can open without logging in (see the hosting section below). Copy that page's URL.
2. Pick a frame that tells the story: a face, the product in use, or the result. Avoid black opening frames and blurry transitions.
3. Add a play button in an image editor: a clear triangle in a circle, centered, with enough contrast to be seen on small screens.
4. Size it to your content column. Export it at the width of your email's main column (often twice that width for sharp display on high-resolution screens) and compress it so the email stays light.
5. Insert the image and link it to the video URL. Add the same link to a short text line under it, such as "Watch the video (2 min)".
6. Write the alt text, for example "Video: how to set up your account in 3 steps (2 min)".
7. Send a test to Gmail, Outlook and a phone, with images on and off, and click every link.

In Mailpro, the steps for adding a linked video preview to a message are in the help article how to embed a video in a message.

What makes a video thumbnail people click?

• A promise in the image: a short overlay such as "See it in 90 seconds" works better than a logo.
• The duration, in the image or the caption. People click more easily when they know it's short.
• One video per email. Two or three thumbnails compete with each other and with your main call to action.
• Text around it. A thumbnail is an image like any other, so keep a healthy balance of copy and visuals. Our guide to the image-to-text ratio in newsletters covers that balance.

Should you use an animated GIF instead of a video?

Use an animated GIF when movement is the selling point, for example a feature in action, a product turning, or a before-and-after, and keep the still thumbnail when one frame already says enough. A GIF doesn't replace the video: it is a teaser that loops a few seconds and links to the full version.

• Keep it short: a 3 to 5 second clip is usually enough to show the action.
• Keep it light: fewer frames, fewer colors and a smaller size load faster on mobile data. Aim for well under a megabyte.
• Make the first frame work alone: some versions of Outlook display only the first frame, so put the play button and the key visual there.
• Avoid fast flashing: it is uncomfortable for many readers and can be a risk for people with photosensitivity.

How to embed video in email with HTML5 (and when it's worth it)

An HTML5 video embed is worth it only when a large share of your list opens on Apple Mail and you have someone comfortable with email code. The principle: a video element pointing to an MP4 file (H.264 is the most widely supported format), a poster image shown before playback, and a fallback, usually the same linked thumbnail, for clients that don't support the tag.

The fallback is not optional. Without it, Gmail and Outlook users see nothing at all. And because the fallback is the thumbnail method anyway, most senders skip the embed and use the thumbnail for everyone. If you try it, test it carefully across clients before every send.

Where should you host the video for an email campaign?

Host the video on a page you control or on a video platform, never in the email itself. The right choice depends on what you want the viewer to do next.

Whatever you choose: set the video to public or "unlisted", not private, so every recipient can watch it. If you collect viewing data, say so in your privacy notice, as you already do for email tracking under GDPR.

When does video in email marketing actually help?

Video in email marketing helps when showing is faster than explaining: a process, a product in use, or a person the reader should trust. It adds little to a short announcement that a sentence can deliver.

Welcome and onboarding sequences are a natural home for a short "getting started" video: it is the moment new subscribers are most willing to watch.

Video email marketing examples you can adapt

Here are three example structures (invented copy) you can reuse. Each has one video, one clear action, and enough text to work without the image.

1. Onboarding email

• Subject line: "Your first win in under 2 minutes"
• Body: one sentence on what they'll learn, then the thumbnail "Watch: set up your first project (1:45)"
• Under the video: "Prefer reading? Follow the written guide." and a button "Open my account"

2. Product launch email

• Subject line: "New: see the feature you asked for"
• Body: a GIF preview of the feature working, linked to the launch page with the full video
• Under the video: three short bullets with the benefits, then "Try it now"

3. Tutorial or tips email

• Subject line: "3 shortcuts that save you 10 minutes a day"
• Body: a thumbnail with the duration, then the three shortcuts written out as a list
• Under the video: "Watch all three in one video" plus a link to the help page

Mentioning "video" in the subject line is fine when the email really contains one; just don't promise a video and send a sales pitch.

How do you make a video email accessible?

Make a video email accessible by making sure the message works without the image and the video works without sound. Concretely:

• Descriptive alt text on the thumbnail or GIF: say it's a video, what it shows and how long it lasts. See our definition of alt text.
• A text link next to the image, so screen-reader users and people with images turned off can still reach the video.
• Captions or subtitles on the video itself. Many people watch on mute, on mobile, in public places.
• A transcript or written summary on the video's page for people who prefer reading.
• No fast flashing in GIFs, and enough contrast on the play button and any overlay text.

For a broader checklist, read our guide to accessible and inclusive email marketing.

How do you measure the results of video in an email?

Measure video emails by the clicks on the video link first, then by what happens on the video page. Your email platform sees the click; it can't see the viewing itself, which happens on the website or platform.

1. Clicks on the video link: how many recipients clicked the thumbnail, the GIF or the text link. With Mailpro's email click analysis you see clicks per link, so you can compare the thumbnail with the text link or the button.
2. Click-through rate compared with similar emails: compare the email with video against your usual emails of the same type, not against your whole history.
3. Viewing on the page: plays and watch time, reported by your video host or website analytics.
4. The action after the video: sign-ups, purchases, demo requests or feature use. This is the number that tells you whether the video was worth making.

To learn something useful, test one thing at a time: the same email with a still thumbnail versus a GIF, or with and without the video, sent to two comparable halves of a segment.

Common mistakes with video in email

• Pasting a platform's embed code into the email and sending without testing.
• Attaching the video file to a campaign.
• A thumbnail with no play button, so nobody realizes it's a video.
• A heavy GIF that loads slowly or not at all on mobile data.
• A private video that asks recipients to log in or request access.
• The video as the only content: if the image doesn't load, the email is empty.

FAQ: video in email

Can you autoplay a video in an email?

No, not in Gmail or Outlook. Even where HTML5 video works, autoplay is unreliable and usually muted. An animated GIF is the closest thing to autoplay: it moves as soon as the email opens and links to the full video.

How do I embed a YouTube video in an email?

Take a screenshot of the video (or use its thumbnail), add a play button, insert the image in your email and link it to the YouTube URL. The YouTube embed code itself will not work inside an email.

Can I send a video as an attachment in an email campaign?

You shouldn't. Video files are heavy, many servers reject large attachments, and every recipient has to download the file. Host the video and link to it instead.

Does adding video to an email hurt deliverability?

A linked thumbnail or a light GIF doesn't cause problems in itself; it is just an image and a link. Large attachments and emails made of a single image with almost no text are what to avoid.

What is the best video length for email marketing?

As short as the job allows: one task, one message, one product. If you need more time, split the topic into several short videos and send them across a sequence.
