After I have approved your cold email Loom:
Download it
Run the download through Auphonic at https://auphonic.com/ to enhance the audio. This will make it sound good even if your mic and acoustics suck.
Download the optimized video
Reupload it to Loom and get the link
Title it something relevant like "How I do XYZ"
Add a thumbnail to it if possible. It should be your face smiling, but it shouldn't look/be edited or look like a YouTube thumbnail. It needs to be casual.
