To send personalized videos via LinkedIn with Lemlist, upload your CSV and map each lead’s LinkedIn profile URL to the unique ID field, export the generated videos, add a video_link custom variable to your Lemlist message, then import the video CSV and launch. Send the video as a follow-up after the connection is accepted, because LinkedIn blocks previews in first messages to non-connections.

​
Key takeaways

  • Map the LinkedIn Profile URL to the unique ID field when uploading your CSV so each lead gets the right video.
  • After generating videos, click Export Generated Videos to download a CSV with a video link column, then re-import it and map video_link to your custom variable.
  • Insert the video with a custom variable in your message, e.g. Hey [First Name], I created a video for you: #{{video_link}}.
  • Only send the video as a follow-up after a connection is accepted — LinkedIn blocks previews and images in first messages to people you’re not connected with.

📹 How to Send Dynamic Videos via LinkedIn Messages Using Lemlist

Sending personalized videos through LinkedIn messages can significantly boost engagement. This guide walks you through the process of using Lemlist to send dynamic video messages effectively.

​
🔧 Prerequisites

  • A Lemlist account
  • A list of leads in CSV format
  • LinkedIn profiles for each lead

​
🧩 Step 1: Upload and Map Your CSV

  1. Go to your Lemlist campaign.
  2. Click the button to upload your CSV file.
  3. During the mapping step, make sure to:
  • Map the LinkedIn Profile URL to the unique ID field.
  • Optionally, set a custom background using the LinkedIn profile or a custom image URL.
💡 Make sure to connect your LinkedIn account within Lemlist first so it can use LinkedIn profile backgrounds.

​
🎥 Step 2: Export Generated Videos

  1. After video generation, click Export Generated Videos.
  2. A new CSV file will be downloaded, including a video link column for each contact.

​
💬 Step 3: Prepare Your LinkedIn Message

  1. Go to the campaign editor in Lemlist.
  2. Add a custom variable:
  • Click on Add Variables → Custom Variable.
  • Name it something like video_link.
  • Click Save.
  1. Compose your message using the variable:Hey [First Name], I created a video for you. Be sure to check it out: #{{video_link}}
🛑 Important:
If you’re not already connected with the recipient on LinkedIn:
  • Do not send the video in your initial connection request.
  • Instead, send it as a follow-up message after the connection is accepted.
LinkedIn blocks previews and images in first messages to users you’re not connected with.

​
📂 Step 4: Import Leads into Lemlist

  1. Go to your lead list in Lemlist.
  2. Click Import → CSV File Import.
  3. Upload the CSV you downloaded earlier (with the video link column).
  4. During mapping:
  • Toggle off any unnecessary fields.
  • Map video_link to your custom variable.
  • Map unique ID to the LinkedIn Profile URL.
  • Adjust other fields (e.g., map contact name to first name).

​
🚀 Step 5: Launch Your Campaign

  • Once the mapping is complete and your variables are properly set, launch the campaign.
  • Lemlist will automatically insert the video link and LinkedIn will generate a video preview when sent (as long as it’s a follow-up message to a connection).

​
✅ Summary

By following these steps, you can:
  • Personalize your outreach with video
  • Ensure LinkedIn displays a video preview
  • Send effective, dynamic follow-up messages
