To send dynamic videos in Instantly, generate your AI-personalized videos in Sendspark, click Share Campaign, and select Instantly to copy the snippet. In your Instantly email, switch to Code View and paste the snippet where you want the video, then switch back. Every lead on your list receives a video personalized for them.

​
Key takeaways

  • Copy the dynamic video snippet from Sendspark via Share Campaign → Instantly.
  • Paste it inside Instantly’s Code View where you want the video, then switch back to the regular view (resize the placeholder if needed).
  • Use Preview and change the email address to see how the video renders for each lead.
  • Videos are matched by email, so use the same lead list in Instantly that you used in Sendspark and generate videos in advance.
  • Unibox works differently. The snippet’s variables don’t resolve there, so insert the thumbnail and hyperlink it by hand using the GIF URL and video link from your campaign’s CSV export.
Sendspark makes it easy to send AI personalized videos in Instantly emails. So you just paste one “dynamic video snippet” in Instantly, and all of the leads on your list will receive personalized videos make for them.

How to send AI-personalized videos in Instantly

  1. First, you’ll want to generate the AI-personalized videos in Sendspark for each of your contacts. More on that here.
  2. Then, click “Share Campaign”
  3. Search for “Instantly,” and click on the “Instantly” button. This will copy a dynamic video snippet to your clipboard. ​Sendspark Share Campaign dialog with Instantly integration option highlighted
  4. Go to to your Sequence in Instantly, and click into the email in which you’d like to send a video.
  5. Switch to “Code View” and paste your Sendspark dynamic video snippet when you want the video to appear in your email. ​Instantly email editor in Code View with Sendspark dynamic video snippet pasted
  6. Switch back to the regular view, and you should see your placeholder snippet. It pastes a little large by default — feel free to resize it as you’d like. ​Instantly email editor in regular view showing video placeholder resized in email
  7. Click on “Preview” to see how this video will look for prospects. You can change the email address to see how this will render for each of the leads on your contact list. ​Instantly email preview window displaying personalized video for specific lead contact
If it doesn’t look right, check…
  1. Did you generate the video for the email address that you’re previewing in Sendspark? (If you haven’t made a video for them in advance, there won’t be anything to see here!)
  2. Are you using the same lead list in Instantly that you used in Sendspark?

Share a dynamic video in Instantly’s Unibox

Unibox needs a different approach. The snippet above relies on Instantly’s sequence variables, and those don’t resolve the same way in Unibox, so you place the video yourself using two columns from your campaign’s CSV export.
  1. In Sendspark, open Share Campaign for your dynamic video campaign and download the CSV file.
  2. In the CSV, find the GIF URL column and copy the value for the lead you’re writing to.
  3. In Instantly’s Unibox, click Insert image, paste the GIF URL, and click Insert. The video thumbnail appears in your message.
  4. Back in the CSV, copy the video link for that same lead.
  5. Select the thumbnail you just inserted, click the link button, and hyperlink it to that video link.
Step 5 isn’t optional. Without the hyperlink the thumbnail is only an image, so recipients have nothing to click through to.
Unibox is built for replying to one person at a time, so this is a per-message process. To personalize across a whole list from a single paste, use the sequence method above instead.

Frequently asked questions

Unibox doesn’t resolve the sequence variables the snippet depends on. Insert the video by hand instead: paste the GIF URL from your campaign’s CSV export as an image, then hyperlink that thumbnail to the video link from the same row. See the Unibox steps above.
Open the email step in your Instantly sequence, switch to Code View, and paste the dynamic video snippet where you want the video to appear. Then switch back to the regular view, where you’ll see the placeholder — it pastes a little large by default, so resize it as you like.
Click Preview in Instantly and change the email address to see how the video renders for each lead on your contact list.
Two common causes: you haven’t generated a video for that email address in Sendspark (there’s nothing to show if the video wasn’t made in advance), or you’re using a different lead list in Instantly than the one you used in Sendspark.
Yes. Generate the AI-personalized videos in Sendspark for each contact first, then copy the Instantly snippet. Videos are matched to leads by email address, so they must exist before the email sends.
