What to Include in Your Email Signature (Complete Guide)
There’s no shortage of advice on email signatures, but most of it falls into two camps: either it’s so vague it’s useless (“be professional!”) or it tells you to add everything and the kitchen sink. This guide takes a different approach. We’ll work through exactly what earns a place in your signature, why, and what to cut without guilt.

The hierarchy rule — most important info first
Before getting into specific elements, here’s the principle that should govern everything else: put the most important information first, and let everything else follow in descending order of usefulness.
Your name and title go at the top because that’s what establishes who you are. Your contact details follow because that’s what the person needs to reach you. Social links, banners, and supplementary information go last, because if the email gets truncated or the recipient stops reading, they’ve still seen the things that matter most.
This sounds obvious but most people get it backwards — they put the company logo large at the top, then name and title, then a cluster of social icons, and then, buried at the bottom, their actual phone number. The logo doesn’t need to be the hero. Your contact information does.
If you want to see how this plays out visually, the email signature design guide covers layout patterns in detail. For now, hold the hierarchy principle in mind as we go through each element.
Must-haves: the non-negotiable five
These belong in every professional email signature regardless of industry, seniority, or personal preference. If any of these is missing, your signature is incomplete.
1. Full name
Your full name, not a nickname and not just a first name. If you go by a preferred name that differs from your legal name, that’s fine — use the name you’d introduce yourself with professionally. Bold it slightly or use a larger font size (14–16px) so it reads immediately.
2. Job title
Be specific. “Marketing Manager” tells someone more than “Manager”. “Senior Software Engineer, Platform Team” is better than “Software Engineer” if the team context helps. Avoid vanity titles like “Chief Happiness Officer” unless that genuinely is your official role — these tend to undermine credibility with people outside your company culture.
3. Company name
Link it to your company website. Plain text company names are a missed opportunity — if someone is unfamiliar with your company, a clickable link lets them learn more without having to Google it. If you’re a freelancer, your company name might just be your own name, which is fine.
4. Phone number
One phone number only. If you have a direct line, use that over a main switchboard. If you have both a mobile and an office line, pick the one where you’re most reliably reachable. Format it as a clickable tel: link so mobile users can tap to call. Include your country code (+1, +44, etc.) if you communicate internationally.
5. Email address
Yes, even though they already have it. Email addresses get lost when messages are forwarded, printed, saved as PDFs, or quoted in other contexts. Your email address in your signature means your contact info stays intact regardless of how the email travels. Make it a mailto: link so it’s clickable on desktop too.
Quick check: Open your current email signature. Does it have all five? If yes, you have a functional signature. Everything from this point is about making it better, not fixing something broken. You can build or update yours in the NeatStamp editor free.
Should-haves: strong additions for most people
These elements add real value in most professional contexts. If you’re unsure whether to include them, start with your industry and role — the section below on per-industry recommendations will make it clearer.
LinkedIn profile link
This is the closest thing to a universal “should include” outside the core five. Most business recipients will visit your LinkedIn profile before or after a meeting — giving them a direct link saves them the step of searching for you. Link to your personal profile, not your company page. The professional email signature guide has more on how to present this cleanly.
Company logo
A logo reinforces brand recognition and makes your signature look polished. Keep it small — 150–200px wide, under 20KB file size. Use PNG with a transparent background so it works on both light and dark email backgrounds. If you’re a solo freelancer with a complex logo, a clean wordmark often looks better in the small format a signature allows. See the email signature with logo guide for sizing specifics.
Website URL
Your company website or personal portfolio. For most people this is already covered by linking the company name — don’t list the URL as separate text unless it’s a different URL from what you’ve linked on the company name. Freelancers and consultants should absolutely include their portfolio URL.
Headshot
Particularly valuable in sales, consulting, real estate, coaching, and any other role where building personal rapport matters. A small, professional photo (80–100px square) helps recipients put a face to a name before a first meeting. In technical, back-office, or traditionally conservative fields (corporate law, investment banking) it can look out of place. Use your judgment based on what others in your company do.
Nice-to-haves: situational extras
These can add genuine value in specific situations. The question to ask before including any of them: “Does this help the people I email most, or does it help me feel like I’ve got a thorough signature?” Be honest with the answer.
Calendly or booking link
If people regularly need to schedule time with you, a booking link eliminates back-and-forth. Works well for consultants, salespeople, recruiters, and anyone else whose work involves a lot of meetings. Not worth including if you only occasionally need to book calls — in that case, just offer times in the email body.
Promotional banner
A banner image below your signature is a low-friction way to promote a launch, event, or piece of content to everyone you email. Keep it to 600px wide, 100–150px tall, and make sure it links somewhere useful. Rotate it when the promotion changes. This is a Pro feature in NeatStamp — the email signature best practices guide covers how to use banners without them feeling spammy.
Pronouns
Adding your pronouns (she/her, he/him, they/them, etc.) is a personal choice and increasingly common in many workplaces. The main benefit is normalizing the practice so that colleagues who need to share their pronouns don’t feel like they’re the only ones doing it. Place pronouns directly after your name or in a small, lighter-weight line below your title. The guide to email signatures with pronouns shows formatting options.
Credentials and certifications
In fields where credentials carry real weight — medicine, law, finance, academia — listing your most relevant qualifications after your name or title is expected and useful. Elsewhere, credentials can read as defensive rather than informative. The rule of thumb: list credentials only if they’re relevant to the work you’re doing with this person.
Quotes
Inspirational quotes are usually a mistake. They add length, rarely resonate with every recipient, and can read as self-important. The exception: if you’re a speaker, author, or coach, a short quote (your own, not someone else’s) can reinforce what you stand for. The email signature quotes guide has examples of when quotes work and when they don’t.
What to leave out
This list is more fun to write than the previous ones, because every item on it represents a real mistake I’ve seen repeatedly.
Fax numbers
Unless you work in a field where fax is genuinely still used (some healthcare and legal contexts in certain countries), remove it. It looks dated and adds clutter.
Multiple phone numbers
Pick one. If you list a mobile, office, and direct line, recipients don't know which to use. You've added friction, not helpfulness. The number you list should be the one where you're most reliably reachable.
Inspirational quotes you didn't write
"The only way to do great work is to love what you do" was already tired when Steve Jobs said it. Quotes from other people in your signature communicate very little about you specifically.
Long legal disclaimers (if not required)
Boilerplate disclaimers like "This email and any attachments are confidential" have been tested in court many times and generally provide little actual protection. They make your signature longer and your emails less readable. If your compliance team requires one, it goes in — but don't add one voluntarily.
"Sent from my iPhone"
Turn this off. It's the single easiest signature fix available. It signals you care so little about your signature that you left the default on.
Eight social media icons
Two or three platforms maximum. Choose the ones where you're actually active and where it would be relevant for a professional contact to find you. A row of eight icons linking to accounts you haven't posted on in 14 months helps no one.
"Please think before you print this email"
Environmental guilt messages accomplish nothing except making your signature longer. Anyone who was going to print it will still print it.
Personal Instagram unless it's professionally relevant
Your personal Instagram is probably fine to leave out of work emails. If your Instagram is genuinely professional (you're a photographer, designer, or food blogger), it belongs. Otherwise, keep work and personal separate.
If you’re dealing with required legal disclaimers, the email signature disclaimer guide covers how to handle them cleanly — including how to minimize their visual impact without removing them.
How many lines (and why 4–6 is ideal)
Four to six lines is the most commonly cited best practice, and it holds up. Here’s why that range makes sense.
Below four lines: you’re probably missing something useful — either your title, a contact method, or your company. A two-line signature with just your name and email works for very casual contexts but reads as too minimal for most professional email.
At four to six lines: you can fit name, title, company, phone, email, and one optional element (LinkedIn, website) without the signature visually overwhelming the email. This is the range where it feels intentional and complete.
Above six lines: you’re starting to compete with the email content itself. A signature longer than the message looks odd. And on mobile, where emails are read in a constrained viewport, a long signature forces the reader to scroll through your contact details to get back to the thread.
Example: 5-line signature
That’s it. Five lines. Everything the recipient needs, nothing they don’t. A logo could be added as a visual element alongside the text without adding a text line. A banner could go below without adding to the line count.
Character count and length limits
Some email systems — particularly certain corporate Microsoft Exchange configurations — add a character limit to email signatures. The limit varies but is commonly around 10,000 characters of HTML. A well-designed signature should be well under this.
For plain text, keep your signature under 250 characters if you also send plain text versions of emails. Many email clients automatically generate a plain text version, and a signature that renders beautifully in HTML can look like a wall of tags in plain text. NeatStamp generates HTML signatures with clean, minimal code specifically to avoid this.
For subject lines and preview text: this doesn’t apply directly, but it’s worth knowing that some email clients show a preview of the first few lines of an email, and if your signature appears at the top (unusual but it happens on some reply threads), it will show up in that preview.
Practical tip
If you work at a large company with Exchange or Outlook and your signature keeps getting stripped or truncated, the likely culprit is an IT policy on signature size. Ask your IT team about the limit. In the meantime, simplify until you’re under it.

Frequently asked questions
What are the most important things to include in an email signature?
Your full name, job title, company name, one phone number, and your email address. Those five form the non-negotiable core. Everything else is optional and should earn its place based on whether it adds value for the person reading it.
Should I include my email address in my signature if the recipient already has it?
Yes. Your email address gets stripped out when messages are forwarded, printed, or copied into documents. Including it means your contact info stays complete no matter how the email gets shared.
How many lines should an email signature be?
Four to six lines is the sweet spot for most professional contexts. Below four and you're likely missing something useful. Above six and you're competing with the content of your email for attention.
Should I include inspirational quotes in my email signature?
Generally no. Most recipients find them distracting, and they add length without adding contact information. The exception is if you're a speaker, coach, or author and the quote is your own — in that context it can reinforce your positioning.
Do I need a legal disclaimer in my email signature?
It depends on your industry and jurisdiction. Financial services, legal, and some healthcare sectors require them. For most other businesses, a boilerplate disclaimer adds length without providing real legal protection. Check with your compliance team if you're unsure.
Is it okay to include pronouns in my email signature?
Absolutely. Adding pronouns (she/her, he/him, they/them) to your signature is increasingly common and signals that you respect others' pronouns too. It's a personal choice, but in many workplaces it's actively encouraged.
