Delivery metrics

What the platform measures about its own mail: delivery, bounce and complaint rates over a rolling 30-day window. Rates only, never absolute volume.

Window: Sep 21, 2026 to Oct 21, 2026, UTC. · Computed: Oct 21, 2026, 12:28 PM UTC.

97.9%Delivery rateDelivered, opened or clicked, out of every resolved email.

1.2%Bounce rateBounced, out of every resolved email.

0.0%Complaint rateMarked as spam, out of every resolved email.

Method

How these numbers are produced

  • Last 30 days, rolling: every email created in the window counts, nothing older.
  • Rates only: this page never publishes absolute volume, per-customer or per-domain numbers.
  • Accounts suspended for abuse are excluded from every count.
  • Canceled and unsent emails are excluded: they were never attempted, so they are not delivery failures.
  • Resolved emails are the denominator: delivered, opened, clicked, bounced, complained and failed.
  • Updated hourly: one database read serves the page for an hour.

HTTP availability is measured separately, on the service status page.
