See your letter’s expected delivery date

Your letter's tracking page now shows an expected delivery date, not just its current status — useful for knowing when to expect it without guessing from the mail class alone.

For developers: the CLI now supports --json output on every command (handy for scripting) plus --help on each one, and the full REST API is available as a Postman collection you can import directly instead of copying requests by hand.

• Expected delivery date shown on the tracking page
• CLI: --json output and --help for every command
• A downloadable Postman collection covering the whole API
