Handle no letter selected for postal update
Follow this guide to use the warning path instead of submitting an empty update. The guide then takes you through the correct route, the checks to complete before making changes, the workflow in order, and the evidence to review afterwards.
Where to goAdmin Area → Letter Manager → Sent Letters History → Postal Update Selected
Before you start
- Use an authorised account and confirm the customer, external recipient, template, letter or configuration is the intended one.
- Follow the exact route shown above and verify the stored record, generated file and delivery evidence instead of relying on an alert alone.

Follow these steps
- Select at least one letter.
- If the server warning appears, return to history and select rows again.
- Retry with the intended IDs.

EvidenceVerify the history row, PDF, email metadata, open evidence, signature, public page, client view or postal fields produced by this flow.
Rules the system enforces
- The button is disabled when zero visible rows are selected.
- The controller also rejects an empty ID list and redirects with Please select at least one letter to update.
How to confirm it worked
- The requested letter, template, setting, file or tracking detail is created or updated through the supported route.
- The history row, generated PDF, email/send metadata, public verification, signature evidence, client view or postal display agrees with the action.
- Any warning, missing file or failed send is investigated rather than bypassed.
Security, privacy and operational checks
- Apply least privilege and verify recipient identity before sending or exposing public links.
- Protect PDFs, enclosures, signatures, verification URLs, email-open metadata, IP addresses and customer data under organisational policy.
- Test configuration and deployment changes with controlled records before production-wide use.
- Interpret email opens and e-signatures according to their documented technical limitations.
