Signed, Sealed, Delivered
On July 4, 1776, John Hancock signed his name on the Declaration of Independence in letters so large that King George III could read them without his spectacles. Or so the story goes. The historical accuracy is debatable, but the energy is not. Hancock wanted his identity on record, unmistakable, in a document that would be read by everyone who mattered.
Two hundred and fifty years later, we sign our names dozens of times a day. Not with quills and not on parchment. At the bottom of emails about quarterly reports, lunch orders, and that thread where someone accidentally replied-all to a company of three thousand people.
Your email signature is, quietly, the most-seen piece of personal branding you own. More than your LinkedIn profile. More than your business card (does anyone still carry those?). It shows up in every conversation you start and every conversation you continue. And for most people, it looks like this:
Thanks, John
Or worse:
Sent from my iPhone
There’s nothing wrong with simplicity. But if you’re going to sign your name sixty times a day, it might as well look like you meant it.
Signed
Stevie Wonder released “Signed, Sealed, Delivered (I’m Yours)” in 1970. He was nineteen. The song was the first single he produced himself — wrested from Motown’s assembly line, made on his own terms. It hit number one, and it announced something bigger than a single: Stevie Wonder was going to do this his way.
We built the Email Signature Generator with a similar energy, if not quite the same level of soul. (We are painfully aware of the gap.)
Here is what it does. You fill in your details — name, title, company, email, phone — and the tool builds a live signature preview as you type. Four templates: Classic (photo left, accent bar, details right), Modern (clean layout, accent-colored name), Compact (single-line, perfect for reply chains), and Bold (color banner header, makes a statement).
Everything that isn’t filled in stays hidden. No empty “Phone:” labels floating in the void. No placeholder text that you forgot to replace before you sent that email to a client. (We’ve all done it.)
Pick an accent color. Choose a web-safe font — Arial, Verdana, Georgia, the fonts that actually render in email clients instead of falling back to whatever Outlook feels like showing you that day. Toggle between light and dark preview backgrounds, because your signature needs to survive both.
The whole thing runs in your browser. We don’t see your name, your email, your phone number, or that incredibly long list of acronyms following your name. (Honestly, how many certs do you really need to share?) Nothing is uploaded. Nothing is stored. Close the tab and it’s gone.

Here’s where it gets interesting.
Email signatures are, technically, just HTML. But they’re a specific, hostile dialect of HTML that most web developers would rather not think about. Email clients — Gmail, Outlook, Apple Mail, Thunderbird, Yahoo — each render HTML differently, and Outlook in particular uses the Microsoft Word rendering engine. Yes, Word. The thing you use for memos. That’s what’s interpreting your signature’s visual layout.
This means no CSS grid. No flexbox. No <div> tags doing anything useful. Your signature needs to be built with <table> elements and inline styles, the way we built websites in 2003. Every color, every font size, every margin — inline, on the element, no stylesheet.
We did this so you don’t have to.
The generated HTML is table-based, inline-styled, and tested against the rendering quirks of the major email clients. The social icons — and there are eight of them — use nested tables with border-radius and background-color to create colored circles that render consistently without relying on external image servers. LinkedIn, GitHub, X, Facebook, Instagram, YouTube, and two platforms you won’t find on most signature generators: Nostr and Bluesky.
If you’re on those platforms, your email signature should say so. Nobody else is giving you that option yet.
For photos and logos, you have two modes. Paste a URL to a hosted image, and it works everywhere — Gmail, Outlook, all of them. Or upload an image directly, which embeds it as base64 data in the HTML. The tool tells you clearly which mode you’re using and warns you that base64 images may not display in Gmail. We’d rather be honest upfront than have you troubleshoot a broken photo after you’ve already sent thirty emails.
Three photo shapes: circle, rounded, square. Because apparently this is the kind of decision that matters at 11pm on a Monday.
Delivered
The copy-and-paste workflow is the part where most signature tools fall apart. You’ve designed something beautiful, and now you need to get it into Gmail without it turning into a pile of plain text with mysterious spacing.
Copy Signature puts the formatted HTML on your clipboard as rich content. Open Gmail, go to Settings, scroll to the signature editor, paste. It arrives looking exactly like the preview. Outlook, same thing. Apple Mail, same thing.
Copy HTML gives you the raw source code, in case you need to paste it into an HTML field or hand it to your IT department.
Download HTML saves a self-contained file that you can open in any browser or import into Thunderbird (which has a “signature from file” option that makes this trivially easy).
And because we know that “go to Settings, scroll to Signature” is more steps than it sounds like when you’ve never done it, the tool includes step-by-step installation guides for Gmail, Outlook, Apple Mail, and Thunderbird. Right there on the page, collapsible, out of the way until you need them.
The Part Where We Talk About the Other Guys
Most email signature generators want something from you before they give you anything. An email address. An account. A “free trial” that turns into $4/month if you forget to cancel. Some of them process your data on their servers. Some of them watermark the free version with their own branding. Some of them generate the signature and then hold the “copy” button hostage behind a paywall.
We looked at nine competitors while building this tool. Two of them run entirely in your browser. Two out of nine. The rest require your data to touch their servers at some point in the process.
Ours is number three. Everything happens on your device. There’s no account to create, no watermark to remove, and no subscription that starts ticking the moment you forget about it.
John Hancock didn’t need a SaaS subscription to sign his name. You don’t either.
What’s Next
Tool number thirty-eight is live, and Phase 4 is two features from the finish line. The site now has 63 pages, 38 tools, and a privacy guarantee that hasn’t wavered since day one.
We’ll keep building. And if there’s a tool you wish existed — one that respects your data and actually works — we’d love to hear about it.
In the meantime: go sign your name. Make it look like you mean it. Stevie would approve.
