Deliverability autopilot
Most email APIs make deliverability your problem. NoticeAPI watches it for you: every bounce and complaint is tracked against rolling thresholds, and if your traffic starts hurting your reputation, sending pauses before Gmail and Outlook start filtering you — which is far easier to recover from.
What runs automatically
| Auto-suppression | Hard bounces, complaints, and provider blocks are suppressed account-wide instantly. |
| Health monitoring | Bounce and complaint rates over a rolling 24h window. Paid plans pause at ≥5% bounces or ≥0.2% complaints; the Free tier is stricter. You're emailed when it happens, and support resumes you after the list issue is fixed. |
| Warm-up ramp | Daily limits grow day by day for new accounts (200 → 500 → 1,000 → … on paid plans), protecting your domain during its most fragile period. |
| Broadcast compliance | Marketing sends always carry a working unsubscribe link and one-click List-Unsubscribe headers — Gmail/Yahoo bulk-sender rules are satisfied by construction. |
What it means for you
Watch the Metrics page: the charts show your rates against the RISK and PAUSE lines. If a send returns 403 account_paused, your account crossed a threshold — check Metrics for the reason, clean the list (typos, stale users, purchased data), and contact support to resume. Transactional sends from healthy traffic are never affected.
Why we're strict
Sending infrastructure is shared. One customer blasting a scraped list degrades delivery for everyone on the platform — so we'd rather pause a bad list in minutes than let it burn a domain for weeks. The thresholds are tuned to never trigger on legitimate transactional traffic.
