BylineSig — AI-designed animated email signatures
AI designs you a bespoke animated email signature — palette, motion, typography — and it's in your Gmail sixty seconds later.
Name, role, and exactly the details you want — every social (LinkedIn, GitHub, X, YouTube, Instagram, portfolio…), phone, company, email. All optional, all yours to toggle. Your photo and company logo animate right into it, on Pro.
One sentence. The AI picks the motion, draws the palette, sets the type — designed for you, not pulled off a template shelf.
One click installs it in Gmail, Outlook, or Apple Mail. We host the animation and keep it online — dark mode included. Change anything later by just asking.
Every animation below is a real GIF from our engine — see one you like, make your own from it in seconds.

Yes — that's the hard part we obsess over. The signature is email-safe HTML with the animation as a hosted GIF, the one format every major client renders. Tested in real inboxes: Gmail web & app, Outlook, Apple Mail, dark mode included.
One honest detail most tools won't tell you: classic Outlook on Windows draws email with Word's engine, which shows a GIF as a still image instead of animating it. So we build every signature so its first frame is the finished design — those recipients see your complete signature, just without the motion. It never shows up as an empty box.
No. Clean standard HTML, no scripts, no tracking pixels. It's the same technique corporate signature tools have used for years — ours just looks better.
Tell it in plain words — "more teal", "bigger name", "calmer motion". It edits the design you already have rather than starting over, so nothing you liked changes. Saved signatures keep the same image URL when you edit them, which means Gmail recipients see the update without you reinstalling anything.
Email clients load images from a URL. We host yours so it loads instantly and keeps working — once a signature is saved to your account we keep that file online, because it's already sitting in every email you've sent. Edit it and you get a fresh signature to install; already-sent mail keeps the version it was sent with. Pro also lets you download the GIF + HTML files any time.
