Resolved after 1 day, on September 3, 2025.
We have identified an increase in error responses for Universal Email Campaign links for clients integrated Sendgrid services, this potentially includes those using Sendgrid, Braze + Sendgrid, Klayvio and other ESPs utilizing sendgrid API. End users should be resolving to the fallback URL in cases where we receive an error from Sendgrid endpoints. We have reported this issue to Sendgrid and will continue to work with them to a resolution.
