Mailbox provider email status

Use this page to check sender-side email delivery status across major mailbox providers, including Google Mail, Gmail, Yahoo, Outlook, iCloud, GMX, Proton Mail, QQ, 163.com, Mail.ru, Yandex, and Naver. A provider can be online while senders still see deferrals, soft bounces, mailbox-full responses, policy blocks, or temporary rate limits. Tatami tracks those delivery signals so teams can spot trouble before customers report it.

This status page focuses on email deliverability, not consumer app availability. That means bounce rate, deferral rate, relative volume, and normalized failure categories matter more than whether a mailbox website loads in a browser. If Gmail, Outlook, Yahoo, or another inbox provider starts rejecting or delaying mail, the chart should show the shift in delivery health.

We refresh this report hourly and show a privacy-safe view of the last 24 hours. It is useful when you need a quick answer to questions like "is Gmail having email delivery issues", "is Outlook rejecting messages", "are Yahoo deferrals up today", or "is iCloud email delivery degraded" without digging through raw logs.

About This Data

Metrics are generated from delivery events indexed by Tatami and grouped into major mailbox-provider families. Providers with low sample volume are marked Low Data. This report intentionally excludes recipient addresses, sending domains, source identifiers, tenant identifiers, project names, and IP addresses.
