Haha, exactly this. I've built and successfully been using Unspam[0] for this reason since about a year ago. In corporate/business world, anything where SDR sales are involved this form of automated AI outbound mail has picked up a lot. Tools like Apollo automates this AI process (both finding leads to mail, and then crafting the mail).
For interest sake, users of Unspam that have a title of CEO on their Linkedin see about ~10% of all mail making it into their inbox be categorised as spam (leadgen, recruitment, or software dev services).
