Production role

Where this block earns its place

Treat the component as one production section inside a larger message system. It should support the send goal, survive handoff, and remain easy to review before compilation.

Lifecycle

For reusable email sections that support product, customer, and operational messages.

Workflow context

Typically used in

These relationships help buyers understand the block as part of a send, not as an isolated catalogue item.

Security notification

Drive immediate, safe action while reducing confusion during urgent incidents.

Implementation

Practical QA before handoff

Keep the checks short and action-oriented. The goal is to help teams decide whether this block is ready to enter a workflow.

Review every CTA href after the ESP rewrites or tracks links.
Confirm image assets are absolute HTTPS URLs before handoff.
Check the mobile preview before placing this block into a full workflow.
Check contrast carefully between the dark background and any transparent logo asset you drop in.
Keep the header shallow so it does not become an obstacle for keyboard and screen-reader users.
Gmail (Web + Mobile): Primary spacing, stack order, and CTA rendering stay stable in Gmail web and mobile views.
Outlook Desktop (Windows): Dark logo rows are stable, though Outlook can tighten padding around the image wrapper.
