What is an email signature generator?
An email signature generator turns your contact details into the block of lines that sits under every email you send. You type your name, your job title, a phone number and a link or two. You get back a formatted signature you can paste straight into your email app's signature settings.
Here is what this one makes from a typical set of details. This is the plain-text version, line for line:
Maya ChenAccount Manager · Northwind Traders+1 (555) 010-2030 · [email protected]northwind.exampleLinkedIn: https://linkedin.com/in/mayachen
The formatted version has the same lines, plus your font and accent color. The phone number dials when someone taps it on a phone. The email address opens a new message, and the website and LinkedIn links open in a browser. The preview on the page updates on every keystroke, and you can see it before you type anything: until you add your name, it fills the empty fields with grey sample details.
There's no account, no email field before the copy button, and no "made with" link stuck to the bottom of your signature. You fill in the fields, copy, and leave.
Why a signature is harder than it looks
A signature is six lines of text. Typing it into Gmail's settings box takes two minutes. So why do so many people use an email signature generator at all?
Because the signature doesn't live in your email app. It lives in your recipients' apps, and you don't control those. One client might open your email in Gmail on a phone. Another opens it in classic Outlook for Windows, which draws email with a word-processor engine that ignores most modern web layout. Someone else forwards it twice, and every app on the way gets a chance to strip something. A signature that looks sharp in your own inbox can arrive as a stack of broken boxes.
The fix is old and boring. You build the signature as a single table, with the styling written onto every piece of text instead of in a stylesheet. Gmail strips stylesheets from signatures. Classic Outlook ignores flexbox and grid. A plain table with inline styles is the one format every major email app renders the same way. Writing that by hand means typing font-family and color into every table cell. Nobody should do that for a phone number.
That's the real job of an email signature maker. And it's where the category goes wrong. Most signature generators are a funnel wearing a form. You type your details, then hit a sign-up wall before you can copy. Or the free tier gives you one signature and stamps a link back to the vendor under every email you send. Or the team plan is billed per seat per month, for something you'll set up once and never touch again. A signature is not a subscription. This email signature maker hands you the HTML and that's the whole transaction.
It works the same for a freelancer sending their first invoice, a new hire whose manager just said "set up your signature," and a 12-person company that wants everyone's to match.
How the email signature generator builds your signature
The Email Signature Generator runs in your browser, every time you press a key. Nothing is uploaded, stored or sent. Here is what the generator does with each field before it writes the HTML.
- Names and titles are tidied. A name pasted with stray spaces or a line break comes out as a clean
Maya Chen. - Phone numbers are shown exactly as you typed them. The link behind them keeps only the digits, plus a leading
+if you typed one. A number needs at least 7 digits to become a link. - Email addresses become a
mailto:link when they have an @ and a dot after it. - Website and social links get
https://added if you left it off. Any other kind of link, such asjavascript:orfile:, is refused and shown as plain text. - Social links are labelled from the address. Up to three are kept.
- Special characters are escaped, so a company called
Tom & Jerry <Co>shows up as written instead of breaking the HTML.
Here are a few inputs and what the generator actually returns for them:

LinkedIn, X (from x.com or twitter.com), Instagram, Facebook, WhatsApp, GitHub, YouTube and TikTok all get their own name as the label. Any other site is labelled with its address, minus the www..
Copy signature puts two things on your clipboard at once: the formatted signature and the plain-text version. Your email app takes whichever it can use. The full Maya Chen signature above comes out at 1,436 characters of HTML, well under Gmail's 10,000-character signature limit.
Customizing the email signature template
Each layout below is an email signature template you can fill in and restyle. Every option changes the look, never the content. Switching layouts or fonts doesn't clear a single field.
| Option | Default | Choices | What it does |
|---|---|---|---|
| Layout | Stacked | Stacked, side by side, compact | Where the image sits and how many lines the details take |
| Font | Arial | Arial, Georgia, Verdana, Trebuchet MS | The typeface for every line |
| Accent color | #1F4E79 | Any six-digit hex color | Colors the company name, the links and the side rule |
| Social links | None | Up to 3 | Text links, labelled from the address |
| Photo or logo | None | An https:// link to an image | An 80-pixel-wide image with your name as its alt text |
| Footer note | None | Up to 500 characters | Small grey text under the signature, line breaks kept |
Stacked puts the image on top and the details underneath, with a thin accent line down their left edge. Side by side puts the image on the left, a 2-pixel accent rule in the middle and the details on the right. Compact squeezes everything into two lines. For the Maya Chen details, that reads Maya Chen · Account Manager · Northwind Traders, then +1 (555) 010-2030 · [email protected] · northwind.example · LinkedIn. Compact suits people who send lots of short replies and don't want a six-line block under each one.
The fonts are limited to four on purpose. Email apps don't load web fonts, so a fancy typeface falls back to whatever the recipient's computer has. These four are on nearly every machine, so what you see in the preview is what people get. Georgia reads as traditional and a little formal. Verdana is wide and easy to read at small sizes. Arial and Trebuchet MS are the safe middle.
For the accent, use your brand color if you have one. A darker shade usually reads better as link text than a bright one. If your brand guide gives the color in RGB, run it through the HEX to RGB converter to get the hex code. If you don't have a brand color yet, the color palette generator will suggest a few.
Common problems and how to fix them
Most signature trouble happens after the copy, inside the email app. If yours isn't behaving, here's what to try first.
The image doesn't show up
The photo or logo field takes a link to an image that's already online, not an upload. Email apps strip images pasted straight into a signature, and a hosted copy would need to stay online forever for every email you've ever sent. So paste the address of an image that's already public, like the logo on your company website. It has to start with https://. Gmail and Outlook block images on plain http:// links, so the generator refuses those and tells you why. It refuses data: images for the same reason.
The phone number won't dial from abroad
The link dials exactly what you typed, minus spaces and brackets. 020 7946 0958 dials as a UK number from inside the UK and nowhere else. Type it as +44 20 7946 0958 and the link becomes tel:+442079460958, which works from any phone in any country. The generator never adds a country code for you, because guessing wrong would dial a stranger.
A link shows as plain text
If a message appears under a link field, the generator didn't like what you pasted. Usually it's a link that doesn't start with http or https. The text still appears in the signature exactly as you typed it, but nobody can click it. Paste the normal web address instead.
Before you send a single real email, send yourself a test. Open it on your phone and, if you can, on a computer running a different email app. A signature you checked once looks right on every email after it. Skip the check and you might find a broken one six months later.
The color didn't change
The accent needs a six-digit hex color like #7A3E9D. Type red and the generator keeps the default #1F4E79 and tells you so. The color picker next to the box always gives a valid code.
Related tools for work email
A signature is usually one small piece of a bigger task. If you need a handwritten signature image to sign a document or a PDF, that's a different job. The Signature Generator lets you draw or type your name and download it as a PNG. Starting a new job and writing your first emails? The email subject line generator gives you a few subject lines to pick from. If you're on the other end of the job hunt, the cover letter generator drafts the letter. The resignation letter generator handles the polite exit from the old job, so you can update the signature on the new one.
Frequently asked questions
How long can an email signature be?
Gmail caps signatures at 10,000 characters, and the formatting counts toward that. A full signature from this generator, with name, title, company, phone, email, website and a LinkedIn link, is about 1,400 characters, so you have plenty of room. The real limit is your reader. Four to six lines is plenty. Longer than that and people skim past it, and some apps fold it out of sight in a reply thread.
Can I make matching signatures for my whole team?
Yes, one person at a time. Treat the first one as your company's email signature template: set the layout, font and accent color once, then change only the personal fields for each person and copy again. Switching fields never resets the design. There's no bulk upload and no team plan, because nothing is saved. Each signature takes about a minute, and nobody pays per seat for a block of text.
Why does the preview show someone else's details?
Those are grey sample details, so you can see the layouts before you type anything. They disappear as soon as you add your name, and the copy buttons stay off until you do. Any field you leave blank is simply left out of your signature.
What's the difference between Copy signature and Copy HTML?
Copy signature copies the formatted signature, the way it looks in the preview. That's what you want for pasting into Gmail, Outlook on the web or Apple Mail. Copy HTML copies the raw source code. Use it for apps that take an HTML file or code instead of a paste, like classic Outlook for Windows when pasting goes wrong, or Thunderbird.
How do I change my signature later?
Come back and type the details again. Nothing is saved between visits, which is also why nothing you type can leak. It takes about a minute. If you change jobs often, keep the plain-text version in a note somewhere and paste the fields back in from there.
Can I use this for a personal email signature too?
Yes. Leave out the job title and company and you get a short personal signature: your name, a phone number, maybe one link. The email signature generator only shows the fields you fill in.
