How do I handle email bounces and suppressions? #67

from commune import CommuneClient
client = CommuneClient(api_key=os.environ["COMMUNE_API_KEY"])

def safe_send(to, subject, text, inbox_id, thread_id):
    suppressed = {s.email for s in client.delivery.suppressions()}
    if to in suppressed:
        print(f"Skipping {to} — suppressed")
        return None
    return client.messages.send(
        to=to, subject=subject, text=text,
        inbox_id=inbox_id, thread_id=thread_id,
    )

metrics = client.delivery.metrics(inbox_id=inbox_id, period="7d")
print(f"Delivery rate:  {metrics.delivery_rate:.1%}")
print(f"Bounce rate:    {metrics.bounce_rate:.1%}")
print(f"Complaint rate: {metrics.complaint_rate:.4%}")

if metrics.bounce_rate > 0.05:
    print("WARNING: Bounce rate above 5%")
if metrics.complaint_rate > 0.001:
    print("CRITICAL: Complaint rate above 0.1% — domain at risk")

if payload["event"] == "message.bounced":
    recipient = payload["data"]["recipient"]
    reason = payload["data"].get("reason", "unknown")
    mark_email_bounced(recipient, reason)  # update your CRM
