Degraded performance — Contacts, campaign statistics, and email/SMS processing delays

We have identified the cause of the issue affecting some services. Our team is working on implementing a fix to mitigate the impact.

What you may notice:

• Errors or timeouts when accessing or updating contacts in the application and via the Contacts API
• Campaign reports showing outdated open statistics, and delayed open-event webhooks
• Delays in transactional email delivery
• Delayed SMS delivery status updates
• Automation workflows involving contacts may run with delays

Important: no data has been lost. All emails, events, and status updates are safely queued and will be delivered and processed automatically once service is restored — campaign statistics will backfill on their own; no action is needed on your side.

This issue started at 09:34 UTC on August 26, 2026.

We sincerely apologize for the disruption. Next update within 30 minutes.

We will continue to share updates as we progress toward resolution.

We have implemented a fix and restored the affected database cluster. Contact operations in the application and API are back to normal, and transactional email delivery has caught up.

Remaining queued events are now being processed: campaign open statistics and open-event webhooks are backfilling and may appear delayed for a short while longer. SMS delivery status updates are recovering as well.

No data has been lost — all queued emails, events, and updates are being processed automatically, and campaign statistics will complete backfilling on their own. No action is needed on your side.

We are monitoring the platform closely to confirm full recovery. Next update within 30 minutes.

We have identified and stopped the cause of this incident, and our team is now working on fully restoring the affected systems. We currently expect this to complete within approximately the next hour.

Until then, you may still notice:

• Errors when creating or updating contacts
• Delays in sending emails (campaigns and transactional)
• Outdated campaign statistics and delayed webhooks
• Delayed SMS delivery status updates

No data has been lost — all emails, events, and updates are safely queued and will be processed automatically once service is restored. No action is needed on your side.

We apologize for the extended disruption and thank you for your patience.

We have applied the required fix and all services have been restored. Contact operations, email sending (campaigns and transactional), campaign statistics, webhooks, and SMS status updates are back to normal, and any remaining queued events are catching up automatically.

No data was lost during this incident — no action is needed on your side.

We are now monitoring the platform closely to confirm stable operation before marking this incident as resolved. We apologize for the disruption and thank you for your patience.

The issue has been resolved, and all affected services are now functioning normally.

Thank you for your patience while we worked to address the issue.
