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.

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

  1. Enter your email — ProSignature pulls your company's logo, colors and links from your website automatically.
  2. Pick one of 13 professionally designed templates and drop in your details.
  3. Tune the design — colors, fonts, social-icon style and a call-to-action button.
  4. 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.
