What's New
Instead of full-page refreshes while waiting on client approval, the send card now polls a dedicated lightweight action for only the fields that change — deliveries, bounces, decisions. The polling pauses when your tab is hidden and stops the moment a client decides, cutting unnecessary network traffic and preventing re-renders across the entire page layout.
Preview email and Excel download buttons now display spinning loaders while fetching, so you see immediate feedback without layout shift.
Read-only estimates (approved, sent to client) now collapse their Source and trailing action columns to reclaim table space on the right edge.
Bug Fixes
Webhook signature verification failures now log diagnostic fingerprints (secret hash, timestamp, payload size) without exposing the secret itself — making it easier to troubleshoot Resend integration issues.
