Is there a way to have submissions automatically deleted after a specified period?

We have a newspaper where does inclusion of ads, which had been online for 14 days. After that the submissions should be deleted automatically. 

I await the response. 

thank you

You can delete submissions automatically, but it deletes immediately, not 14 days later. But, since you will also receive the submission in email, this might be what you want:
