Is there anyway to create/manage a draft or an email via API? Or at least just the Email templates?

I can't find it when looking in the API and it isn't syncing my drafts from Gmail :(

If not possible, Is there someway to at least add the Pipedrive-tracking to my own emails for example via the bcc-email-address? An example could be to send the email via gmail, bcc the Pipedrive-email and then still see the openings and link-clicks :)

What I want to do is create the emails via our backend and then making sure that the only thing the sales-person should do is adding a relevant image, double check the email and click send. But I want to be able to create the email message (or template) via our API :)
