Email footer: what it is and how it differs from an email signature

An email footer is text added to the bottom of a message that the sender did not type. The word covers two different things, and that is why the question gets confusing: a footer that a company’s mail system appends to every outgoing message, and the small print at the end of a person’s own signature. This page separates them, shows both on one message, and gives the admin steps for Google Workspace and Exchange Online.

Google’s own help page adds to the muddle. The Gmail page for users describes a signature as text “automatically added at the end of Gmail messages as a footer”, while Google’s page for administrators uses “footer” for a rule that users cannot change. In this article, the email footer means the company-wide one unless we say otherwise.

Email footer vs email signature, side by side

	Email signature	Admin-level email footer
Who writes it	The person, or a company design the person fills in	An administrator, once, for everyone
Where it is set	In the user’s mail settings	In the Google Admin console or the Exchange admin center
Can the sender change it	Yes	No. Google says users cannot change or remove it
Seen while writing	Yes	No. Google says users do not see it when composing
Typical content	Name, title, phone, logo, links	Confidentiality notice, registration details, a promotion
Personal details	Yes	Only if the system can fill them in (Exchange has tokens for this)
Risk	Some people forget it or change it	Applied to threads and replies in ways you must test

One message, three layers

Here is how one real-looking message is built. The company here is made up.

1. What the person types: the question, then “Kind regards, Amara”.
2. What the signature adds: her full name, title, direct number and the firm’s logo.
3. What an admin footer adds, in transit: a one-sentence confidentiality notice and the firm’s registered address, after everything else.

The person sees layers one and two while writing. Google’s page says users do not see an appended footer when composing, which is why you test layer three by sending a message to a mailbox you can open. When a firm uses the in-signature method instead, layers two and three are one block, as below.

Boxed layout with the legal line built into the signature. An admin-level email footer would add similar text after it, outside the box. The firm and person are made up.

What is a business email footer used for?

A footer of this kind is common where the same text must appear on every message. Google’s page for administrators says the text can serve legal compliance, company promotions or a standard signature. The usual contents are:

• A confidentiality or privacy notice.
• Company registration details that your country or regulator expects. We do not guess these: see the UK page for the one we have read from an official source, and ask your lawyer about your own. This is general information, not legal advice.
• A link to a privacy policy.
• A short promotion, such as an event, that changes every few months.

For wording examples, see our article on email disclaimer examples. Keep the text short. A footer that is longer than the message is read by no one.

How an admin adds an email footer in Google Workspace

These steps follow Google’s Workspace Help page for user signatures and footers, read in October 2026 (the page showed an update date of 1 October 2026).

1. In the Google Admin console, go to Menu, then Apps, Google Workspace, Gmail, Compliance. You need the Gmail Settings administrator privilege.
2. Scroll to the Append footer setting and click Configure or Add another rule.
3. Give the setting a name, then enter the text in the box under “For all outbound email messages, append the following footer”. Use the formatting tools if you want.
4. By default the footer goes only to recipients outside your organisation. To add it to internal mail too, tick the box to append it within your organisation.
5. Click Save and check that the rule appears in the Append footer table.

Google says changes can take up to 24 hours. If you add an image, it recommends 70 to 100 pixels high by 300 to 400 pixels wide, with a maximum of 100 pixels high by 1,000 pixels wide.

How an admin adds a business email footer in Exchange Online

These steps follow Microsoft Learn’s page on organization-wide disclaimers, signatures, footers or headers, read in October 2026.

1. In the Exchange admin center, go to Mail flow, then Rules.
2. Select Add a rule, then Apply disclaimers.
3. Name the rule, then choose who it applies to. To limit it to outgoing mail, choose a condition such as a recipient outside the organisation. By default, mail flow rules apply to incoming and outgoing messages.
4. Under “Do the following”, keep append a disclaimer (or choose prepend a disclaimer for the top) and select Enter text.
5. Choose a fallback action, and under Except if add an exception so the footer is not added again in a long conversation.
6. In the rule settings, leave Enforce selected, or choose Test without Policy Tips to log results first. Review the rule and select Finish.

Three details are worth knowing. The footer text can include HTML and inline CSS, and images through an IMG tag. It also supports tokens that pull values from the sender’s directory entry, such as %%DisplayName%%, %%Title%% and %%Phone%%. And the fallback matters: if the rule cannot modify a message (Microsoft’s example is an encrypted one), the default Wrap option puts the original inside a new message as an attachment, while Ignore delivers it without the footer and Reject returns it to the sender.

Which approach should you choose?

• Admin-level footer: choose it when a notice must be on every outgoing message and nobody should be able to remove it. You need admin access to Google Workspace or Exchange Online, and you should test replies and encrypted mail.
• Footer line inside the signature: choose it when you want the notice styled with the logo and colours, and you accept that each person installs their own signature. This is how emailfooter works: the company admin sets the layout and the legal line once, and employees follow the steps for their mail app. It does not push anything into mailboxes, so a person who never installs it will not have it.
• Both: a short signature for identity and an admin footer for the notice. This is a common split when a firm has strict compliance rules.

Frequently asked questions

What is an email footer?

Text added to the bottom of a message that the sender did not type. It is either an admin-level footer added by the mail system, or the small print at the end of a signature.

What is the difference between an email footer and an email signature?

A signature is personal and the sender can edit it. An admin-level footer is set by an administrator for everyone, and the sender cannot change it. See the table above.

Can employees remove the company footer?

Not in Google Workspace: Google’s page says users cannot change or remove an appended footer. In Exchange Online the footer is added by a mail flow rule that an admin owns, not by the sender’s Outlook.

Should I put a disclaimer in the footer?

Only if your business needs one. Keep it to a sentence or two, and ask a lawyer about the wording. General information, not legal advice.

Why does the footer appear twice in a thread?

Usually because the rule runs on every reply. Exchange’s page suggests adding an exception that looks for unique text in the footer, so it is added only to the original message.
