Minor August 30, 2026 Email API & SMTP delivery disruption – API Services (Email API), Email Infrastructure (SMTP Server)
Started Aug 30, 2026, 08:46 PM UTC· resolved Aug 30, 2026, 08:46 PM UTC

Between July 14 and the morning of July 16, 2026 (UTC), outbound email processing through the Email API and SMTP relay was disrupted, with sending dropping to near zero on July 14 and 15. Service was restored on July 16 and has operated normally since. The extended red period previously shown on this page through late August was a monitoring error, not a real outage. A paused uptime check left an incident open, so the page kept showing the services as down even though email sending and delivery continued the whole time. We have fixed the monitoring and are recording the real July 14 to 16 disruption here for transparency.

We experienced a brief service disruption earlier today affecting API requests and dashboard access. Some users may have seen 429 (rate limit) errors when sending emails or accessing the dashboard. What happened: A routine infrastructure update temporarily caused increased traffic to our API gateway, which exceeded a provider rate limit. What we did: We identified and resolved the issue. All services are now fully operational. Impact: API email sending was intermittently unavailable for ~2 hours Dashboard login and page loads were affected No emails were lost — queued emails will be delivered normally Current status: All systems operational. We apologize for the inconvenience. If you're still experiencing issues, please contact us at [email protected]. — Unosend Team
