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.

Transactional

For account, billing, support, and security sends where clarity matters more than decoration.

Account access

Useful when the recipient needs a direct, trusted route back into their account.

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.

View workflow

Password reset

Keep account-access copy direct, secure, and easy to verify.

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 token expiry, account-access wording, and plain fallback links.
  • State the alert reason in text so the message remains understandable without coloured callouts.
  • Make the follow-up action descriptive, especially if the CTA sends the user to a security review flow.
  • Gmail (Web + Mobile): Primary spacing, stack order, and CTA rendering hold up in Gmail web and mobile views.
