How to delete emails with business process that are currently used in another business process

Hi all,

I have some business processes, that serve the purpose of sending pre-configured emails manually to my contacts. However, the users are allowed to choose not to send the email - this way, the business process is not completed, it stays running.

My issue is that I have a GDPR deletion business process, that should delete every email connected to an affected contact. However, if the contact had at least one email that was not sent (but was left a draft), the deletion business process will be stuck, because the email to be deleted is still used in a running business process.

I am looking for any suggestions on how I could get around this problem.
