AI — Pull the spam trap before you send — one hit can torch the domain. The catch-all is risk-scored, your call.
Stop the bad addresses at the source.
Bought, scraped and aging prospect lists are full of spam traps, role accounts and long-dead mailboxes. Hit a few and your bounce rate spikes, mailbox providers throttle you, and the whole domain you've worked to warm up gets torched.
- Here's the fix. Run every prospect list through EmailListChecker before your first send. We flag spam traps, disposables, role accounts and catch-all domains, and grade each address with a real confidence score — so you only mail inboxes that exist and actually accept. Your sender reputation stays intact and your replies go up.
Outcomes, not just a status column.
The point isn't a green checkmark — it's what changes for your team when the data is finally trustworthy.
