- postmortem Apr 24, 2026, 02:24 PM UTC
## Summary On April 24, 2026, we identified an issue affecting confirmation emails on form submissions. Forms created or republished after April 21, 2026 were affected. Forms created prior to this date were unaffected. All other form functionality including submission recording and list assignment continued to work correctly throughout. ## Root Cause A defect introduced in a recent platform release caused confirmation emails to fail silently on affected forms. The form submission itself completed successfully in all cases, only the confirmation email was impacted. ## Resolution A workaround is now in place and confirmation emails are sending correctly for affected accounts. Our engineering team is working on a full resolution. If you are still experiencing issues please reach out to our support team, and we will ensure the workaround is applied to your account promptly.
