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.
For the product overview, read the deliverability autopilot guide.
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. Pro and Custom pause at stricter production thresholds; Free pauses earlier because it can send real mail without a card. 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. Free ramps more slowly and stays capped at 100/day; paid workspaces get more headroom as healthy traffic builds history. |
| Broadcast compliance | Marketing sends always carry a working unsubscribe link and one-click List-Unsubscribe headers, so 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.
