The app does the cleaning. 65+ labels, domain intelligence, and risk signals. Human experts help with strategy and analysis whenever you need them.
Every address sorted into three buckets, with labels and reasoning behind each decision.
No flags found. Domain checks out, validation passed, no risk signals. These are clear to send.
Each address comes with specific labels explaining why it landed here. Context matters. How you segment and send to these decides the outcome.
Each address comes with specific labels explaining why. Invalid, trap-likely, disposable, or other risk signals. Don't send here.
You also get the validation and DNS data that informed each decision. Not just buckets. The full picture.
Domain behavior, history, and patterns across your entire list. Context, not just existence. An address that "works" can still be dangerous.
Traps, role accounts, toxic domains, disposable patterns. The things that don't bounce but still hurt you. Built from years of deliverability experience.
Not just labels. You get the thinking behind each decision so you understand why, and can make smarter calls next time.
