What the disclaimer actually does
The block of small print at the bottom of a firm’s email usually does three things. It labels the message as confidential and possibly privileged. It instructs a mistaken recipient to notify the sender and delete it. And it signals intent, which may matter later if someone argues the message was never meant to be confidential.
Those are real, if modest, benefits. A label on a message that genuinely is privileged is a reasonable habit, and many firms put it at the top or in the subject line of the messages that warrant it rather than on every email they send.
What it can’t do
- It doesn’t encrypt anything. The message and its attachments travel and sit on mail servers exactly as they would without the footer.
- It doesn’t control copies. The email stays in your Sent folder, the client’s inbox, both providers’ systems and their backups, and on every device that syncs either mailbox.
- It doesn’t stop forwarding. A client who forwards your advice to a friend, or replies from a shared family account or an employer’s system, takes it outside your control. No footer changes that.
- It doesn’t make a message privileged. Whether privilege attaches depends on what was said and between whom, under the rules of your jurisdiction.
The case firms most often miss: the client’s own inbox
A disclaimer protects nothing when the risk is on the client’s side. A client writing from a work account, a shared family computer or a phone someone else can unlock is exposing the conversation before your footer is ever read. This is common in employment, family and business disputes, which are exactly the matters where the other side may control or see the client’s accounts.
The practical fix is to move sensitive exchanges off email entirely: give the client a private place to read your messages, send documents and sign, opened from a link on their own phone.
Practical steps
- Keep a short label, used on purpose.Mark the messages that are actually privileged; don’t rely on the boilerplate under every email.
- Ask early which account and device the client uses.If it’s a work address or a shared device, switch channels before anything sensitive is sent.
- Move documents and advice into an encrypted channel.Something that keeps the content unreadable to anyone but your firm and the client, and out of both inboxes.
- Check your own jurisdiction’s guidance.Rules and ethics opinions on electronic communication vary by state and change over time.
Where Brun fits
Brun’s client portal gives each client one end-to-end encrypted page for messages, documents, signatures and progress updates. Brun stores only ciphertext. The emails Brun sends the client say only that something new is waiting, so nothing from the matter lands in their inbox. Before a matter exists, the first message from your contact form is encrypted the same way.
