The email suppression list

An address only ever appears on this list after something real happens with an email BrandOps actually sent, never from a person clicking a button.

• An address is added to the suppression list automatically after a real hard bounce or spam complaint on an email BrandOps sent. There's no "add to suppression list" action anywhere in the UI.
• Two reasons show up: Bounced (a hard/permanent bounce) and Complained (the recipient marked an email as spam).
• Soft bounces (a temporarily full mailbox or an unreachable server) are logged but don't suppress anything. Only a Permanent bounce type triggers suppression; a soft-bounced address might still be perfectly deliverable later.
• The list lives at the organization level (Settings → Organization → Suppression), not per-brand, so an address suppressed here is blocked across every brand in your workspace.

Suppressions are event-driven, not something BrandOps guesses at.

• Suppressions arrive via a dedicated Resend webhook listening for email.bounced and email.complained events. It's configured separately in your Resend dashboard, with its own signing secret, isolated from BrandOps's reply-handling and engagement-tracking webhooks.
• Every webhook call is verified with a Svix signature before anything is processed; an unverified request is rejected outright.
• A repeat delivery of the exact same bounce or complaint event (Resend/Svix occasionally redelivers) doesn't count as a second occurrence. BrandOps recognizes the duplicate and only increments the Occurrences count on a genuinely new bounce.

One bounce quietly touches more than just this list.

• BrandOps looks up every organization where that email address is already known (as an Outreach Lead, a Client, a Subscription customer, or an Order customer) and suppresses the address in every one of them, not just the org that happened to send the bounced email.
• Alongside the suppression row itself, BrandOps flips the matching records so the block is visible where you'd actually look: any Outreach Lead with that email moves to unsubscribed (unless it's already converted), and marketingOptOut is set to true on any matching Client, Subscription, or Order.
• Suppression is also checked live at send time, not just applied once, so an address that bounced weeks ago and gets re-imported or manually re-added as a fresh Outreach Lead is still caught before a new email goes out to it.
• If the bounced address isn't known under any org's Leads, Clients, Subscriptions, or Orders at all (for example, a bounce on a signup or password-reset email), there's nothing to suppress and nothing is recorded.

What you actually see on the Suppression tab.

• Each row shows the email, the reason (Bounced or Complained), a Detail column combining the bounce subtype and message where available, how many times it's occurred, and when it was last seen.
• The list is currently read-only and informational only; there's no way to manually clear or remove an entry from this screen yet.
• It's paginated with a Load more button, sorted by most recently updated first.
