You emailed the wrong person

Short answer: Autocomplete picked the wrong name and the message is gone. Attempt recall immediately, then focus on the document: if it was sent as a controlled link you can revoke access so it stops opening. Contact the recipient directly, ask for deletion, and record what was exposed and whether it was ever opened.

Why this happens so often

Address autocomplete resolves a few typed letters into a full address, and two contacts frequently share a first name. It is not carelessness — it is an interface that commits faster than a person can check.

What to do first

  • Attempt recall if the recipient is inside your organisation.
  • If the document went out as a FINIS link, revoke access straight away. This works even after the message was read.
  • Check the access record. Knowing it was never opened changes the severity of the incident entirely.

What to say

Be short and factual: the document was sent in error, please delete it, and confirm that you have. Most people comply immediately.

When it involves personal or regulated data

Misdirected email involving personal data may be reportable. An access record showing whether the document was ever opened is valuable evidence in that assessment.

Preventing the permanent version of this mistake

You cannot stop autocomplete from being wrong. You can stop the wrong click from producing a permanent copy. Sending confidential documents as FINIS links means the wrong recipient holds a link you control rather than a file you don't.

How FINIS handles this

FINIS is a post-send control platform for documents. You send the file as a FINIS link instead of an attachment, and the controls stay with you.

Revoke access

End access to a document after it has been sent, even after it was opened.

Track opens

See when the document was opened and how it was accessed.

Device lock

Restrict the document to approved devices.

Destroy

Erase the document itself and keep a record that it was destroyed.

Sharing control

Control whether recipients can pass access on to others.

Auto-expire

Give the document a lifetime at the moment you send it.

Questions

What should I do if I sent an email to the wrong person?

Attempt recall, revoke access to the document if it was sent as a controlled link, contact the recipient and ask them to delete it, and record the incident.

Can I stop them opening the attachment?

Not with an ordinary attachment. With a FINIS link you can revoke access or destroy the document before or after it is opened.

How do I know if they read it?

A document sent through FINIS records when it was opened and how it was accessed.

Does this count as a data breach?

It can, if personal or regulated data was exposed. Follow your organisation's incident process; an access record helps you assess the actual exposure.
