Newsletter workflow

Newsletter is set up for teams that need repeatable, template-driven output instead of one-off manual design work.

✓Connect newsletter updates to uploaded assets, approved templates, and API-safe render jobs.
✓Keep all remote image dependencies blocked so production renders use controlled assets only.
✓Use idempotency keys when the same request can be retried by an automation tool.

Receive product updates, automation patterns, template ideas, and practical notes for visual operations.

Before using this workflow in a campaign, validate the template, expected dimensions, asset ownership, and output access path.

✓Render the same payload three times and compare output hashes for deterministic behavior.
✓Confirm local fonts are present in the approved whitelist before launch.
✓Monitor completed and failed jobs from the logs page during rollout.
