Proofy Saved Our Domain Reputation by Catching Dead Emails and Spam Traps

We’ve been running large cold email campaigns for a while, and high bounce rates were slowly killing our domain reputation. I picked up Proofy to run a quick cleanup on a legacy list of about 15,000 leads, and it flagged a ton of dead emails, catch-alls, and spam traps that our CRM totally missed.
