Webflow change history: [RESOLVED] Reports of form submission notification emails not being delivered for some customers

Webflow’s critical incident disrupted form submission notification emails for some customers, starting 2026-09-21 00:45 UTC and resolving 2026-09-22 17:05 UTC (40 h 19 min). Webflow attributed the issue to an upstream provider; notification delivery was restored, while form submissions continued to be saved and webhook delivery was unaffected.
