Deliverability autopilot
Email Deliverability Autopilot for Small Teams
NoticeAPI watches the delivery signals small teams usually have to babysit. Bounce and complaint rates feed automatic suppressions, warm-up ramps, operator alerts, and account pause controls before a bad list or broken workflow harms your domain.
{
"error": "account_paused",
"message": "Sending paused after bounce or complaint thresholds were crossed.",
"nextStep": "Review metrics, clean the issue, and contact support to resume."
}Automatic suppressions
Hard bounces, complaints, provider blocks, unsubscribes, and manual blocks stop future sends to risky recipients.
Rolling health checks
NoticeAPI tracks bounce and complaint rates against plan thresholds and pauses production sends when traffic becomes unsafe.
Warm-up ramp
New accounts start with conservative daily sending caps that grow as healthy traffic builds history.
Visible outcomes
Metrics, logs, email timelines, and webhooks show the delivery events that triggered each safety action.
How it works
From test send to production traffic.
Verify the sender domain
Production sending starts with DNS records for ownership, SPF, DKIM, and DMARC alignment.
Send through the shared pipeline
REST, SDK, SMTP, broadcasts, and automations all feed the same health and suppression layer.
Watch bounces and complaints
Delivery events update metrics and create suppressions so bad recipients stop being retried.
Pause unsafe traffic
When thresholds are crossed, production sending pauses until the account is reviewed and resumed.
Trust
Deliverability controls, not deliverability tricks
Autopilot is a safety system for legitimate product email. It does not promise inbox placement or hide bad traffic; it gives teams real feedback and pauses sends when reputation is at risk.

FAQ
Questions developers ask before switching email.
Does autopilot guarantee inbox placement?
No. It monitors real delivery risk, suppresses bad recipients, ramps volume, and pauses unsafe traffic. Inbox placement still depends on sender quality, recipient engagement, and mailbox provider decisions.
Do sandbox sends pause my account?
No. Sandbox and simulator paths are for safe testing. Production traffic is what feeds the account health thresholds.
What happens when an account is paused?
Production sends fail with account_paused. Sandbox sends still work, and support can resume the account after the list or workflow issue is fixed.
