The incident should be resolved; we have put in mitigations and will continue to monitor. A small percentage of users may see some lingering deliverability issues as we catch up. We apologize for the inconvenience. - 00:00 UTC · postmortem
We extend our sincerest apologies for this outage. On 17 August 2026, between 02:15 and 05:15 PT (09:15–12:15 UTC), all outbound email from Stytch failed, including email magic links, email OTPs, and password reset emails. Service was restored at 05:15 PT. **What happened**: This outage was triggered by abuse of free-tier email sending, a pattern we defend against continuously. In this case, our abuse controls did not engage in time, and a large volume of spam was sent before we intervened. That volume exhausted our sending quota with our primary email provider, which normally handles the majority of traffic. Automated failover and alerting fired, and our on-call engineer fully failed over to our secondary email provider within 20 minutes. That failover appeared to succeed: The secondary provider accepted our sends and reported them as successful 200s. However, the secondary provider was not delivering those emails due to the previous spam volume. As a result, we believed email had been restored when it had not. We received customer reports beginning at 03:15 PT and confirmed the true state of email sends at 05:01 PT. We restored service at 05:15 PT, banned the malicious accounts, and implemented new safeguards against the abuse seen. **Impact**: All email sent during the window failed permanently. Any authentication email a user requested between 02:15 and 05:15 PT never arrived, and users would need to request a new one after 05:15 PT. **Ongoing impact on deliverability**: The spam volume sent from our infrastructure has affected our sender reputation for `[email protected]`. For some time, a higher-than-normal share of legitimate emails may land in recipients' spam folders. We are working with our providers on reputation remediation and expect this to improve over the coming days. No action is required. If your users report missing authentication emails, please ask them to check their spam folder. **What we're changing**: We have already implemented new safeguards against the abuse seen. To prevent future attacks, we are also reviewing our systems and processes, including: * Rate limits and quotas * Verification of failover paths * Abuse detection at signup and message send time

We are currently aware of an upstream incident with Microsoft Outlook impacting email deliveries with several of our messaging providers over the past several days. This has been widely reported across the industry, but Microsoft has not shared any public commentary as of yet. We're looking into any ways we may be able to mitigate this until Microsoft addresses the issue.

During [Cloudflare's 2025-11-18 incident](https://blog.cloudflare.com/18-november-2025-outage/), Stytch's services continued to operate as normal. However Stytch customers that use Cloudflare in their own infrastructure may have seen their requests to Stytch, either client or server side requests, fail to make it to the Stytch API, thus causing their auth flows to fail. Though the Cloudflare incident did not cause any downtime in Stytch services, due to the popularity of Cloudflare, we've created this incident for posterity for customers investigating downtime in their own systems.
