If you want to add personalized/different videos to each lead, you should follow these steps:
1. Create a new column in your file and name it "video".
2. In your Loom video link, go to "Share", then click on the "Embed" tab, and grab the Thumbnail code.
3. Paste the Thumbnail code in the video column for each lead (if you want a different video for each lead, paste the different code for each lead, and please make sure you paste the whole code).
4. Download the CSV and upload it to Instantly.
5. When mapping the columns, use "Custom variable" for the Video column.
6. In your Instantly sequence, insert the Video variable.
7. Preview and send a test email to double-check that the video works. When the thumbnail is clicked, it takes your leads to the Loom video.
If the thumbnail of your Loom video appears broken after following the above steps, please ensure the two settings below are not enabled, as they will remove any images and send emails as text-only.
The "Delivery Optimization" feature in the Options section of the campaign
The "Always send first email as text-only" feature in the Advanced Deliverability setting
