What to Include in a Business Email Signature, and What to Leave Out

A business email signature has one job: tell the reader who you are and the easiest way to reach you or take the next step. That takes five to seven lines. Here is what to include, the order that reads best, examples for different kinds of small business, and what to cut.

WHAT THIS ADDSSignature advice tends to be a gallery of designs. This post is about content: which lines earn their place, which belong elsewhere, and why one clear next step, such as a booking or review link, does more than six social icons. Each example is written for a real kind of small business.

The short list

A business email signature needs fewer lines than most have. In the order they usually appear:

Your name, as customers know you.
Your role and the business name. "Owner, Harbor & Pine Studio" tells a new contact who they are dealing with.
One phone number. The one you answer. Two or three numbers make people guess.
Your website. It is where people check you out before they reply.
An address, only if customers come to you.
Two or three social profiles you actually keep up to date.
One next step, such as booking a call or leaving a review.

Your email address is optional in the signature itself, because it is already on the email. It earns its place when emails get forwarded, so most templates keep it.

The test for every other line is simple: would a customer reading this email on a phone, in a hurry, use it? A direct phone number, yes. A fax number, a second office, a list of every certification, almost never. Anything that fails the test makes the useful lines harder to find, so it goes.

Short beats complete. Everything in the left column is text, so it survives blocked pictures.

Order and layout

People read a signature top to bottom, often on a phone, so put the identity lines first and the contact lines next. Keep each item on its own line or separated clearly, and make phone numbers and email addresses real links so they can be tapped.

A photo helps when you are the business, such as a consultant, a photographer or a tradesperson people meet in person. A logo suits a business with a team. Either way, keep it small and make sure the signature still reads well without it, because some readers block pictures. Our guide to signature images that don't show explains why.

Fonts are worth a thought too. A signature uses the fonts already on the reader's device, so a special web font rarely arrives as you intended. The free signature generator limits itself to fonts every computer has, Arial, Verdana, Tahoma, Trebuchet and Georgia, for that reason.

Examples for different kinds of business

The same short list, adapted. Each one ends with a single next step.

Some trades must show a licence number on advertising and paperwork. Whether that covers email depends on where you work, so check the rule for your trade and state. If it applies, the signature is the easiest place to meet it.

A UK limited company

The UK government's guidance on signs, stationery and promotional material says business letters, order forms and websites must show the company's registered number, registered office address, where it is registered and that it is a limited company. Many UK companies add the same details to their email signature as a small line at the bottom.

What to leave out

Extra phone numbers. Office, mobile and fax lines make people choose. Give the one you answer.
Every social profile. A profile last updated two years ago does more harm than none. Two or three active ones are plenty.
Quotes and slogans. They add length and rarely age well.
Contact details inside a picture. If the picture doesn't load, they are gone, and nobody can tap a number that is part of an image.
Several buttons or banners. One next step gets clicked. Three compete with each other and with the email itself.
Anything that makes it huge. Gmail's help page on creating a signature sets a limit of 10,000 characters, and pictures count towards it. The generator shows your signature's size as you go.

Build it in ten minutes

1. List the essentials

Fill in the planner that comes with this post, or just write the lines down.

2. Choose two or three profiles

Only the ones you have posted on recently and that your customers use.

3. Choose one next step

For a business that lives on referrals, a review link is a strong choice: every email to a happy customer becomes a gentle reminder. Our guide on how to get your Google review link shows how to find it. For a business that sells time, a booking link is better.

4. Build it in the generator

Enter everything, add the button text and link in the "Links and a button" section, and pick one of the four templates.

5. Read it on a phone

Send yourself a test and open it on a phone. Check that the phone number dials when tapped, the website opens, and the button goes where it should. Then install it with the steps for Gmail or Outlook.

If your customer emails, bookings and invoices live in different places, Fynl's Starter plan puts your Gmail inbox beside the customer list and adds each team member's signature when they write from there. The generator itself is free. More free tools are on the free tools page.

DO THISName, role and business, one phone number, your website, two or three social profiles you actually use, and one next step. Put them in that order, as text, and read the result on a phone before you save it.

Questions people also ask

What should a business email signature include?

Your name, role and business name, one phone number, your website, an address if customers visit, two or three social profiles you keep up to date, and one next step such as a booking or review link.

Should I put my email address in my signature?

It is optional because it is already on the email, but it helps when emails are forwarded, so most business signatures keep it.

How many social media links should an email signature have?

Two or three that you actually keep up to date and that your customers use. Inactive profiles do more harm than leaving them out.

Should my signature be an image?

No. Keep the details as text. Some readers block pictures, and a phone number inside an image can't be tapped or copied.
