Acceptable Use Policy

ListSieve helps senders keep lists clean. You may not use it to:

• Verify purchased, rented, scraped or harvested lists, or addresses you have no lawful basis to email.
• Send or support spam, or evade blocklists, spam filters or unsubscribe requests.
• Enumerate or guess addresses (e.g. permutation “finder” attacks against a domain).
• Phishing, fraud, harassment or any illegal activity.
• Resell or overload the Service, or bypass rate limits and quotas.

We may rate-limit, suspend or terminate accounts that break these rules, without refund. Report abuse to abuse@listsieve.com.
