Sending emails from a NextJS app

Hey, I'm trying to send an email to myself using a form on my website - the user fills in the information and the email should end up in my own inbox. I expected tRPC would be the correct way to do this, but I'm not able to get anything through to myself. I also tried a server actions approach, but didn't get anywhere there either, as seen in second screenshot. Does anyone have any experience with this? Am I missing something obvious here?
