List Armor

How does List Armor protect my sender reputation?

List Armor monitors affiliate email activity using seed addresses to detect when affiliates ignore suppression lists or send after unsubscribe. It also maintains centralized suppression lists you can check via API before sending, preventing spam complaints and protecting your sender reputation.

How fast is the verification API?

Our API responds in under 50ms on average. We support batch verification for checking thousands of addresses at once, making it easy to verify entire lists before sending.

How does List Armor help with affiliate compliance?

List Armor distributes seed addresses to your affiliates via suppression lists. When an affiliate sends to a seed address, List Armor captures the email and flags the violation with full forensics including headers, sending IP, and ESP. You get real-time alerts and an audit trail for enforcement actions.

Can I give affiliates access to verify lists?

Yes. Our affiliate portal lets you give partners controlled access to verify their lists against your suppression data without exposing the underlying email addresses. You control permissions and rate limits.

How does seed address monitoring work?

List Armor uses two types of seeds. Suppression seeds are embedded in your opt-out list exports — any email to them means the affiliate is sending to your opt-out list. Journey seeds go deeper: they subscribe to an affiliate's list, receive emails normally, then automatically unsubscribe. After a grace period, any further email is flagged as a violation.
