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.

Onboarding

For activation and lifecycle flows where the block needs to move users to the next step.

Workflow context

Typically used in

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

Trial ending reminder

Increase paid conversion before trial access lapses.

View workflow

Onboarding

Guide a new or returning user to the next activation step.

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.
  • Do not signal urgency using colour alone.
  • Make the timing and required action explicit in text.
  • Gmail (Web + Mobile): Primary structure, spacing, and CTA rendering hold up in Gmail web and mobile views.
