👉 On Loom's 'Share' page, go to 'Embed'-> Click on
'Copy Thumbnail Code'
👉 On Instantly's email editor, click on 'Code View' in
lower right corner and insert the copied code where
you want it.
This is what your code should look like, especially the second last line which starts with "src". This is responsible for creating a thumbnail gif in your email body.
👉 You should now be able to both preview and send
that embedded video (see screenshot below)
