How to keep entry if link fails?

I'm scraping a national organization's directory of local satellite orgs for contact emails. First my scraper grabs the name and telephone number from the directory, then it access the link to the satellite org's site and looks for an email. Problem is, if the link fails (some of the local orgs have defunct sites) the entry is deleted altogether. Is there any way to make sure the parent element isn't deleted just because a child link fails?
