Recipient delivery is part of the workflow infrastructure, not just a decorative email feature. Invite, reminder, resend, voided, declined, and completed notifications all matter when you think about automation or support behavior.

Before you begin

A workflow that depends on recipient notifications

Awareness of the different delivery moments in the lifecycle

A need to explain delivery behavior to an operations or integration team

Know the delivery moments

Notifications cover invites, reminders, resends, voids, declines, and completion-related messages.

Those moments often define when downstream teams notice the workflow at all.

Treat delivery as tracked work

The backend tracks notification deliveries rather than pretending every email was delivered successfully.

That tracking matters when you troubleshoot or build process expectations around email.

Plan fallbacks

If a workflow is critical, decide what your team should do when the recipient needs resend or when delivery is skipped because a transport environment is unavailable.

Operational planning matters as much as the mail path itself.

Pro Tips

Do not assume every delivery issue is a platform outage.

Use reminder and resend intentionally based on the actual problem.

If email is business-critical, document who owns first-response support on your side.
