Deleted lead receiving emails
Hello Marketo Community,
I noticed something very strange with one of the leads in the campaign I'm currently running.
This is a "default" program including three emails, one sent every week. Each email is sent via a different workflow and I only schedule the workflows a few days before sending.
I sent the first email to the database. I got an automatic reply from one of the recipients saying that the email address is no longer active and the person has left the company. I then deleted the lead from my Marketo database entirely.
The campaign carried on, I scheduled the next workflow and the emails were sent. This is where something unexpected happened: I'm still receiving the same automatic reply from this email address. I checked and the lead is still not in my database.
My questions are :
1. How can this be happening? How come that a deleted lead can receive my Marketo emails?
2. How do we prevent this?
Thank a lot for your help.
Claire
