Proof and privacy

Proof of delivery: the recipient’s acknowledgement of receipt, when the carrier provides it.

No account is ever required. Your PDF travels over HTTPS, is stored privately and is never reachable at a public address. Every document is screened for threats, harassment and impersonation before the quote. Proofs of posting and delivery are kept for 10 years, and a paid letter that cannot be posted is refunded automatically.

How it works

  1. Upload your PDF

    Up to 20 pages, 10 MB. No account and no signup.

  2. Enter sender and recipient

    The recipient’s address in Spain, and your return address.

  3. Get the exact price

    VAT included, fixed for 24 hours. Asking for a quote mails nothing.

  4. Confirm and pay

    Pay that one letter by card on Stripe. Nothing is printed before payment.

  5. It is posted

    Printed and posted in Spain as a Carta certificada con aviso de recibo, then trackable by its reference.
