About Registered Mail

Registered Mail is used for international deliveries that require additional tracking information. Here are some key details:

  • Cost: Starts at approximately $30 per letter
  • Delivery Timeframe: Typically delivered in 7–21 days (can be longer depending on the destination and customs clearance)
  • Tracking: Available, but updates may be delayed—especially during international transit
  • Delivery Confirmation: Signatures and delivery are not guaranteed. If a signature for Registered mail is collected upon delivery, it will be mailed back to us and added to your account.

You can select Registered Mail as a mail type option on the Create a New Job page after clicking Send Letter(s).
