Keeping Lead Data Updated for Effective Outreach Strategies

Hi all For those of you who "recycle" lead lists with outreach, how do you make sure your lead data stays up-to-date after the initial list was built? Example: client has a TAM of 30k, we scrape the whole list and start hitting 10k contacts/mo. 3 months later, we go back and contact the 'non-replied' leads again. But, there's a chance that some of these leads have changes job titles, changed companies etc. in the meantime, since the initial list scraping. Anyone got a good workflow for this? We've just been re-scraping lists each time we recycle, but I'd imagine there's a more efficient way to keep the data updated. I was thinking some kind of linkedin profile scraper can be used here, then see if the new data lines up with the old? Any insight appreciated
