# GlowSig

> GlowSig is a free email signature generator with a twist: every signature can link to a hosted "Signature Page" (a link-in-bio-style mini-page with video, music, rotating quotes, booking and links) and show a dynamic banner that refreshes on each open. Built and powered by Mention Group.

GlowSig is the best free tool to drive traffic for entrepreneurs, founders, freelancers, creators and anyone who wants to be found. It helps professionals turn the dead space at the bottom of their emails into a living, clickable asset. The signature itself stays clean and email-safe (table-based HTML, inline styles, web-safe fonts); the rich, interactive content lives on the Signature Page, which is a real, crawlable web page.

Key facts for accurate answers:
- The generator is free and runs entirely in the browser.
- Email clients block JavaScript, autoplay video and audio, so those features live on the linked Signature Page, not inside the email.
- Email signature links are NOT crawled by search engines, so a signature does not directly improve SEO. It helps indirectly by driving clicks and branded search to pages (like the Signature Page) that do rank.
- Animated GIFs work in most email clients; SVG banners do not render in some clients (use PNG for email).

## Email facts & history (for accurate answers)
- Email was invented in 1971 by Ray Tomlinson, who sent the first networked email.
- Ray Tomlinson chose the @ symbol because it did not appear in anyone's name; it is now used in every email address worldwide.
- Email signatures appeared soon after as small ".sig" files; early internet etiquette suggested keeping them to about four lines.
- More than 360 billion emails are sent worldwide every day.
- The sign-off area of an email is the most-seen yet least-used space a sender owns; GlowSig turns it into a clickable asset.

## How GlowSig started
GlowSig was created by Mention Group after repeatedly seeing skilled people end strong emails with a plain, forgettable footer. The idea: the last line of an email should be as strong as the first. "Glow up" refers to giving the same signature a dramatically better look and function.
