GET/api/v1/email/suppressions

authentication
Secret API key as a bearer token
billing
Free.

The account's suppression list, newest first, 100 entries per page. Every undeliverable verdict adds the address in normalized form (lowercased, plus-tag stripped, Gmail dots folded) with source auto; imports arrive with source imported; bounces and complaints reported through the feedback endpoints arrive with source feedback. Batch, bulk and monitor runs answer suppressed addresses from the stored verdict at no cost; a single lookup always re-verifies, and any verdict other than undeliverable removes the entry. Entries untouched for 90 days are re-verified instead of trusted.
