Jul <var data-var='date'>24</var>, <var data-var='time'>09:59</var> PDT Monitoring - We identified an issue that affected the delivery of a small percentage of message webhooks for some Nylas applications in the EU region. The issue primarily occurred between 06:00 and 11:00 UTC on July 24, 2026. Webhook delivery has recovered, and new webhooks are being sent successfully. Nylas applications in the US region were not affected. Customers who would like us to replay message webhooks should contact support@nylas.com as soon as possible and include their Nylas application IDs, when available. Please note that we cannot replay only the webhooks that were not successfully delivered. A replay will resend all message webhooks from the start of the incident through the time the replay is performed and will generate duplicates. Before requesting a replay, customers should ensure that their systems can safely identify and handle duplicate webhook events. We are continuing to investigate the underlying cause and closely monitor webhook delivery.
