A common belief in cold email is that you should never send links in your first email—let alone embed videos—because it guarantees a trip to the spam folder. Many think that adding a video to the initial email will burn your email accounts faster than Usain Bolt. While there is some truth to this, there is also a way to send videos in the first email while maintaining strong deliverability.

In this guide, I’ll break down how I consistently send videos in my first cold emails while maintaining high deliverability and securing an 11% appointment booking rate. I’ll also show you step-by-step how to structure your emails, rotate domains, and ensure your campaigns remain effective.

The Problem With Sending Videos in Cold Emails

When you send the same link to thousands of prospects per day, spam filters quickly detect the pattern. If emails containing that link start receiving high spam complaints, all your emails will eventually get flagged. The result? Low deliverability, wasted efforts, and burned domains.

There are two major reasons why this happens:

• Spam Filters Detect Repeated Links – If a single link appears in thousands of emails per day, ESPs flag it as suspicious.
• Volume Control – Sending large amounts of emails without proper domain rotation can lead to blacklisting.

The key is controlling how and where you link in your emails. Let’s break down how you can do this effectively.

Step 1: Rotating Domains to Bypass Spam Filters

One way to avoid spam triggers is by rotating the domains you use in your links. This means that instead of repeatedly using the same URL, you distribute traffic across multiple domains.

• Link Only to Your Sending Account’s Domain – Instead of linking to external websites, link back to your own sending domain.
• Use Custom Domains for Landing Pages – With a tool like Vinna AI (my SaaS), you can create multiple custom domains that rotate with each email sent.
• Set Up Domain Rotation – In Vinna AI, you can add up to 20 custom domains. Each email will randomly select a different domain, avoiding repetitive link patterns that trigger spam filters.

To add custom domains in Vinna AI:

1. Navigate to the domain settings.
2. Add your desired domains.
3. Follow the simple DNS settings to verify them.

Once set up, integrate them into your email sequences for automatic rotation.

Step 2: Embedding Videos Without Triggering Spam Filters

Once you have your domains set up, the next step is to embed videos in a way that doesn’t flag your emails as spam.

• Use Static Thumbnails Instead of GIFs – Animated GIFs increase email size and are often blocked by ESPs. A static image reduces email load and improves deliverability.
• Use Proper Link Rotation – Rotate your video links with Spintax to ensure variety in URLs.
• Ensure Your Links Match Your Sending Domain – Instead of linking to an external domain like YouTube or Loom, link to a subdomain that matches your email sender.

How to embed the video correctly:

1. Once your video is generated in Vinna AI, click “Copy Snippet.”
2. Customize the video thumbnail.
3. Avoid using first-name personalization in the thumbnail filename.
4. Select a static image instead of an animated GIF.
5. Paste the snippet into your cold email tool (e.g., Instantly).
6. Use Spintax to rotate the domains within the email copy.

Example of a Proper Email Structure

                Hey {first_name},

                I recorded a short video for you explaining exactly how [specific value proposition].

                [Insert Video Thumbnail Here]

                Check it out here: {rotated_video_link}

                Let me know if this resonates with you.

                Best,  
                [Your Name]
                

Step 3: Implementing Spintax for URL Rotation

To further improve deliverability, implement Spintax. This dynamically rotates the domains you use in your emails, making each email slightly different from the last.

Here’s how to do it inside Instantly:

1. Copy your video link from Vinna AI.
2. Replace the static domain with Spintax.
3. Add multiple variations of your domain within Spintax.

Example:

                {random|domain1.com|domain2.com|domain3.com}/video
                

This ensures that each email has a different domain linked, reducing the likelihood of getting flagged by spam filters.

Additionally, you’ll need to edit two places in the email:

• The main hyperlink where users click.
• The image source where the video thumbnail is hosted.

Step 4: Keeping Your Sending Volume Low

Even with all the above optimizations, volume control is key.

• Send No More Than 5 New Contacts Per Day, Per Inbox – Avoid overwhelming ESPs with high email volumes.
• Use Multiple Domains and Inboxes – If you need more volume, set up multiple email accounts to distribute sending.
• Keep Domains At Least 3 Months Old – Aged domains have better reputation and are less likely to get flagged.
• Monitor Spam Complaints – Use email warming tools and ensure your domains remain in good standing.

Step 5: Scaling Safely

Once your system is in place, you can scale up gradually. Start with 5 emails per day per inbox and monitor results. As you see success, increase your volume while keeping an eye on bounce rates and spam complaints.

Final Thoughts

Using videos in the first cold email can work without landing in spam—if done correctly. The key takeaways:

• Rotate your domains to avoid spam detection.
• Embed static thumbnails instead of GIFs.
• Use Spintax to randomize your URLs.
• Keep sending volume low to maintain deliverability.
• Ensure your domains are at least three months old.

By implementing these techniques, you can increase engagement, improve deliverability, and book more meetings with cold email.
