We validate email sign-ups across hundreds of lists to ensure that our customers are receiving good subscribers and preventing them from being targets of attacks. We monitor all usage from our customers to ensure that they are using our service in good faith and only for opt-in emails. We have a strict anti-spam policy and make clear distinctions on allowing email verifications for signups and disallowing bulk verifications on purchased lists, email appending, or directory harvesting.
We are not perfect and encourage that all email administrators to reach out to us before taking secondary measures.
Please report any suspected abuse to email@example.com. ISPs and blacklist administrators are welcome to submit feedback reports to firstname.lastname@example.org. Please include all relevant SMTP transaction logs and we'll take the appropriate action towards the abuser.
