Hello timothy bach,
This one was a head scratcher, the closest solution I found is https://www.email2phone.net/
The only think you might not like is when you reply to these emails using the service, it will record and add the recording as an attachment, not text.
If I come across any other solutions, I will be sure to update them here.
