How to address the envelope

  1. Copy it exactly onto the envelope

  2. Add your return address

    Top-left, your own name and address. A return address is what the post office needs to send the letter back if Cybernet has moved.

  3. Buy the certified service

    Certified, not courier: buy it at the counter, keep the postmarked slip, and the letter to Irvine is traceable from the article number until it is signed for.

  4. Keep the proof together

    Hold on to the letter copy, the receipt and the tracking page.
