A: Hhm.. not sure I get it? You send a message from your own email address to yourself? Or did you use the button where we send you a test voice message?

Spam detectors use a variety of factors, including the existing reputation of your inbox, to decide if something is spam. so if the reputation is really bad, it can be that any email that is not plain text will be marked as spam.

But since you emailed yourself, that shouldn't happen, so I'm not sure. Vocal embeds an image with a link in the email, same as loom for example or many other tools. It's pretty standard so for normal inboxes with normal reputation, there is no harm. But if your inbox already has a suspicious reputation, that can be the thing that makes an email go into spam (as would happen if you sent a Loom over email for example).
