Add model and model_id ?

[tonypartridge]

Ideally adding the model sending the email and the model_id would then mean we can have email transactions for the model.

I built something similar whereby we store the id and model so we can then find the transactions and render them in an action on the model record so users can easily see the status of send emails, but I took it one step further and built malign integration and a web hook so we can show status, deliveries and opens/clicks.
