# List suppressed addresses

> Addresses this business must not write to again, after a hard bounce or a complaint.

<api-operation method="GET" path="/v1/businesses/{biz}/emails/suppressions">
<template v-slot:docs="">

Returned WHOLE rather than paginated — the list is small by nature. Exposed because an invisible block is its own failure mode: "we stopped emailing this customer and nobody can say why" is a support call correct bounce handling does not excuse.
