What counts as delivered

docs://recipes/what-counts-as-delivered — the difference between delivered, opened and read

Use before you tell a lawyer that someone "received", "opened" or "read" a notification. The
words end up in court filings; say only what the evidence shows.

What each event proves:
- message.frozen — the exact message (.eml) and each attachment were hashed and timestamped
  (RFC 3161) BEFORE sending. Proves what was sent.
- transport.sent — our mail provider accepted the message for delivery. Not delivery yet.
- mail.delivery (recipient status "accepted") — the recipient's mail server accepted the message,
  with its SMTP answer and time. This is the delivery evidence: the message reached the
  recipient's mailbox server. When the notification is deemed done and when terms start is stated
  in the notification's own body (art. 8 Ley 2213); quote it, never compute it yourself.
- opened — a tracking image loaded. ALWAYS an indicio, never proof of reading: Apple Mail and
  Gmail fetch images automatically, and many clients block them. Never write "they read it".
- downloaded — someone fetched an attachment through the recipient's unique link (time, IP,
  user agent). Strong evidence of access, still not proof of who.
- acknowledged — the recipient confirmed receipt on the recipient page.
- bounced / complained / deferred — the address failed, was reported as spam, or is being retried.

How to say it:
1. Delivered: "The recipient's mail server accepted the message on <date, America/Bogota>."
2. Opened: "An opening indicio was recorded on <date>; it does not prove the message was read."
3. Nothing after sent: "No delivery answer from the recipient's server yet."

Done when your answer uses only the sentences above, with Bogotá times.

Tips
- Business days follow the Colombian holiday calendar; do not compute deadlines yourself — quote
  the dates the notification detail shows, or ask the lawyer.
- The constancia states the same facts, signed; quote it rather than paraphrase it.
- This is not legal advice; the lawyer decides what to file.
