How to create a professional email signature (with examples)

A signature is the closing frame of every message you send. Done well, it answers "who is this and how do I reach them?" in one glance. Done badly, it is three logos, a legal disclaimer nobody reads and a quotation that makes the reader wince.

Building your signature

1. Start with your name as you want to be addressed, then your role and company.
2. Add one reliable phone number. Two numbers means the reader has to choose; most will choose neither.
3. Include your email address even though it is in the header — people copy signatures into contact records.
4. Add your website, and a single social profile only if it is genuinely professional.
5. Keep the styling minimal: one font, one accent colour, no background image.
6. Add a small logo only if it renders well — images are blocked by default in many clients, so the signature must still read as plain text.
7. Add legal details if your jurisdiction requires them (company registration, VAT number), but keep them compact.
8. Test it by sending to yourself and opening the message on a phone.

What to leave out

• Large images or a banner that dominates the reply chain
• Inspirational quotations
• "Please consider the environment before printing"
• Multiple phone numbers, addresses and social icons competing for attention
• Long confidentiality disclaimers, unless your legal team insists

Mobile readability

More than half of business email is read on a phone. That means a signature should be no more than four or five short lines, with a tappable phone number and no wide tables. Test on a narrow screen: if it wraps awkwardly, cut a line.

Replies and threads

Use a shorter version for replies — name, phone, company is enough. A full signature repeated ten times in a thread makes the conversation hard to read. Many clients let you configure separate signatures for new messages and replies; if yours does not, keep one compact signature and use it everywhere.

Setting it up

In webmail, the signature usually lives under settings and is applied automatically to new messages. In Outlook, it is under File → Options → Mail → Signatures, where you can assign different signatures per account and for replies. On iOS and Android, the mail app has a signature field per account — set it deliberately, or every message will end with "Sent from my phone".

Frequently asked questions

Should the signature include a photo? Rarely. It increases message size, is often blocked, and adds little for most roles.

HTML or plain text? HTML is fine, provided it degrades gracefully. The information must survive being stripped to plain text.

Do I need a legal disclaimer? It depends on your jurisdiction and sector. Where it is not required, it mostly adds noise.

Can each employee have a different signature? Yes, but agree on a template so that the company looks consistent. Fields change; structure should not.
