See exactly what a cleaned list looks like before you buy.

Every address is sorted into one of three categories. Each one gets specific labels explaining why.
Safe to mail. The mailbox is confirmed, the domain is active, and there are no risk signals. Send with confidence.
Use with care. The address is deliverable but carries risk factors like role accounts, catch-all domains, or low engagement patterns. Best for targeted sends, not bulk campaigns.
Do not mail. These addresses will bounce, trigger spam traps, or generate complaints. Removing them protects your sender reputation.
We use 65+ labels across these three categories. The sample above shows a handful -- your report will include every label that applies to each address.
Everything is delivered to a secure folder. Here is what is inside.
Upload your list and get every address labeled with reasoning. Results typically ready in minutes.
