I was wondering how can I store sent emails
I have a send_email() function in a pre_save() and now I want to store the emails that have been sent so that I can check when an email was sent and if it was sent at all.
Another way to look at it: send the mail to your backup email account ex: backup@yourdomain.com. So you can store the email, check if the email is sent or not.
Other than that, having an extra model for logged emails is a way to go.
