What to put in an email signature: the 9 essential elements

The question “what should I put in an email signature” is almost always asked backwards: people start from what they could include, and try to fit everything in. The right starting point is the opposite — what does the recipient actually need? The answer comes down to four elements, plus a few optional ones depending on context.

The four essential elements

1. The full name. First name and surname, in that order, unabbreviated. It is the visual anchor of the signature and the most useful piece of information: it lets someone find the person in a directory, on a professional network, in a CRM.

2. The job title. It tells your correspondent who they are talking to and what they can expect. “Procurement Manager” and “Sales Assistant” do not call for the same reply. A clear title beats a flattering one: “Head of Growth” informs less than “Acquisition Manager”.

3. The company name. Obvious, and yet regularly missing from signatures where the logo is supposed to do the job. When images are blocked — which is the default behaviour for an unknown sender — the name disappears with the logo. It has to exist as text.

4. One direct means of contact. A number, usually. The international format (+44 7700 900123) is the only one that stays reliably tappable from abroad.

With those four elements, your signature is already complete for most purposes.

The five elements that depend on context

5. The website. Useful for a little-known company, superfluous for an established brand whose site the recipient already knows.

6. One to three social icons. Active accounts only, and preferably the company’s. A link to an abandoned account works against you.

7. An action link. A booking link for a salesperson, a support portal for a technical team, an applications page for a recruiter. It is often the most useful element after the name — and the most rarely present.

8. The postal address. Relevant if you receive visitors or if your sector requires it. Otherwise, two lines for nothing.

9. Legal notices. They depend on your legal form, your sector and the nature of the message. There is no universal block — the subject is covered in mandatory legal notices.

What is better removed

The email address. It is already in the header. Repeating it takes a line for information the recipient already has. The only exception: sends from a shared mailbox, where the named address adds something.

Inspirational quotes. They commit the company to a personal register, age badly, and lengthen every message.

“Think of the environment before printing”. Its effect on behaviour is negligible and it adds two lines to hundreds of thousands of messages a year. If the subject matters to your organisation, a real, dated commitment carries more weight.

Ten-line confidentiality disclaimers. Their legal force is weak in most situations and their length makes them invisible. See confidentiality disclaimers.

Three phone numbers. Switchboard, direct line, mobile: the recipient will not know which to pick, and will probably call the wrong one. One, the right one.

The order that works

The eye travels down, and gives up quickly. The following order puts the essentials at the top:

First name Surname            ← largest, darkest
Job title — Company           ← one step down
+44 7700 900123               ← direct contact
[logo]  [social icons]        ← visual identity
Legal notices                 ← small, light grey

The campaign banner, if you use one, sits below that block, separated by a rule. It must never slot into the middle of the contact details — see the campaigns and banners page.

Worth knowing: test your signature by reading it aloud in order. If you hesitate about what to announce first, the visual hierarchy is not established.

The case of reply signatures

In an ongoing conversation, the full signature becomes cumbersome: it repeats at every exchange and ends up dominating the thread. Many organisations therefore define a short signature for replies: name, job title, phone. Three lines.

It is a distinction email clients handle natively, and one a centralised template can enforce without anyone having to think about it — see the editor.

And if everyone chooses what they include?

That is the default situation, and it invariably produces the same result: as many signatures as there are employees, with information missing for some, superfluous for others, and legal notices absent where they would be needed.

The list above only has value if it becomes a shared rule, embodied in a template where the administrator decides what is fixed and what stays free. The method is in how to create a professional email signature.
