The free email signature generator that installs itself
Design a polished, on-brand email signature in a couple of minutes — then push it straight into Gmail, Outlook or Apple Mail. No HTML, no copy-paste guesswork.
Build your signature now — free, no account
Type your details and the signature renders as you go. Copy it straight into Gmail, Outlook or Apple Mail. Nothing is gated: no email address, no signup, no watermark.
Want your company logo, brand colours and social icons pulled in automatically, one of the 13 designed templates, or the signature written straight into Gmail in one click? Open the full editor — the free plan covers all of it.
What a good email signature does for you
You send hundreds of emails a month. Each one ends with your signature — which makes it the most-seen piece of branding you own. A clean, consistent signature builds trust, drives clicks to your website or booking link, and quietly markets you on every reply.
ProSignature's generator turns that dead space into a professional, clickable footer that works across every major email client.
The templates, actually shown
Eight of the thirteen, rendered — these are real output from the editor, not mockups. Each is labelled with the situation it suits, because picking on looks alone is how people end up with a signature that fights the way they work.
Every one arrives already wearing your logo and brand colours once you enter your work email in the full editor — and all thirteen are email-safe HTML, so they render the same in Gmail, Outlook and Apple Mail. More layouts and the reasoning behind each: the examples gallery.
Everything you can add
Logo & headshot
Upload a company logo and a profile photo, crop them to fit, and ProSignature keeps them sharp on every device.
Clickable details
Name, title, phone, website and address — each rendered email-client-safe so nothing breaks in Gmail or Outlook.
Social icons
LinkedIn, X, Instagram, Facebook and YouTube in soft, solid, outline or plain styles.
Call-to-action button
A branded button — Book a call, See our work, Read reviews — with your own text, color and link.
Promo banner
Announce a launch, offer or event with a banner image that links anywhere.
Brand colors & fonts
Pull your palette automatically from your website, or set it by hand.
How the generator works
- Enter your email — ProSignature pulls your company's logo, colors and links from your website automatically.
- Pick one of 13 professionally designed templates and drop in your details.
- Tune the design — colors, fonts, social-icon style and a call-to-action button.
- Click install and ProSignature adds the signature straight into Gmail (or gives you a one-click paste for Outlook and Apple Mail).
Works with every email client
Signatures are built with inline, email-safe HTML — the same approach professional signature tools use — so they render correctly in Gmail, Outlook, Apple Mail, and mobile clients. See template examples or set one up for your whole team.
Generator vs. doing it by hand vs. IT templates
| Typed in Gmail/Outlook | Hand-coded HTML | ProSignature | |
|---|---|---|---|
| Looks professional | Rarely — plain text, uneven spacing | If you know email HTML | Yes — 13 email-safe templates |
| Logo & brand colors | Manual, usually skipped | Manual hosting + markup | Auto-extracted from your website |
| Survives Outlook | Yes (it's plain) | Only with inline-style expertise | Yes — built for client quirks |
| Install into Gmail | Typed in place | Fragile copy-paste | Chrome extension (no permission), or 1-click Google connect |
| Team consistency | None | None | Locked design, per-person details |
What a complete professional signature includes
Identity
Name, role, company — the hierarchy your recipient scans first.
One-tap contact
Phone and site as links, not text; mobile recipients tap, not type.
Brand
Logo and exact brand colors — extracted automatically from your site.
One call-to-action
Book a call, view listings, get a quote — one button outperforms three.
Social proof, selectively
LinkedIn for B2B, Instagram for visual businesses — icons, not URLs.
Legal line if regulated
License numbers or disclaimers, styled to whisper, not shout.
From blank to installed in four steps
- Enter your work email — ProSignature fetches your real logo, colors and socials from your company site.
- Pick one of 13 templates; everything is already branded when you arrive.
- Fine-tune: photo, CTA button, banner, socials — with live Gmail preview.
- Click Connect Gmail & install — the signature is written into your Gmail settings via Google's official API. Outlook and Apple Mail get a clean copy-paste.

Installing it in your email client
Gmail is one click. Everything else takes a minute, and each client has its own quirks worth knowing before you start: adding a signature in Gmail covers the settings people cannot find and the replies default that makes signatures seem to vanish; Outlook explains why the four different Outlooks store signatures in four different places; Apple Mail on macOS covers the “always match my default message font” checkbox that silently strips branding; and iPhone explains why logos rarely survive on iOS. Running several addresses? Gmail keeps a separate signature per send-as address. Need social icons to match your brand? The free email signature icon generator exports transparent PNGs in your own colours. Wondering whether to just ask an AI to write one? Using ChatGPT for email signatures covers what it can and cannot do, and our free email tools collects everything we publish that costs nothing to use. If you would rather understand the underlying format first, HTML email signatures explains why email markup is two decades behind the web.

Create my signature — freeFrequently asked questions
Is the email signature generator really free?
Yes. You can design and install a signature on the free plan with no credit card. Pro unlocks premium templates, the call-to-action button, promo banners and advanced styling.
Do I need to know HTML?
No. You design visually and ProSignature generates clean, email-safe HTML for you. If you ever want the code, you can copy it.
Will the signature look right on phones?
Yes. Signatures are built responsively with inline styles so they hold up on mobile Gmail and Outlook as well as desktop.
Can I add a booking link or button?
Yes — the signature generator includes a call-to-action button with your own text, color and link: a Calendly booking link, your website, a reviews page, anything.
What makes this different from HubSpot's free generator?
HubSpot's tool is a one-off form: no brand extraction, no saved account, copy-paste only. ProSignature saves your design, extracts your brand automatically, installs into Gmail in one click, and scales to teams.
