Email signature generator

Most signature generators produce something beautiful that breaks in Outlook. This one produces a table with inline styles, which is the thing that works.

A French sole trader usually puts its identifiers here.

Preview

Fill a field and the signature appears here.

<table role="presentation" cellpadding="0" cellspacing="0" border="0" style="border-collapse:collapse">

This tool runs entirely in your browser. Nothing you type is sent to Mailbind or to anyone else — there is no server behind this page, which you can verify in your browser’s network tab.

Why signatures break

An email client is not a browser. Outlook on Windows renders HTML with Word’s engine, Gmail strips anything it does not recognise and rewrites the rest, and every client handles dark mode differently. A signature built with modern CSS — flexbox, a web font, a background image, a border radius — will look right in the designer’s browser and wrong in half of your recipients’ clients.

What survives is boring: a table for layout, inline styles on every cell, system fonts, no images, and colours that read on both white and dark backgrounds. That is what this tool emits, and it is why the output looks plainer than the one your agency sent you.

  • Tables, because Word’s engine does not do modern layout.
  • Inline styles, because Gmail removes a <style> block.
  • System fonts, because a web font will not load in a mail client.
  • No images, because they are blocked by default — including your logo.
  • Grey text rather than a brand colour on a coloured background, so dark mode cannot make it unreadable.
A signature travels inside the message, through your provider's server, to a client you do not control.

What belongs in a signature

Less than you think. A name, what you do, how to reach you, and whatever the law where you trade requires. Everything else — a quote, a social icon row, a confidentiality notice nobody reads, an environmental plea about printing — adds weight to every message in a thread and is quoted back into every reply.

If you sell in France as a sole trader, the identifiers belong here or on your invoices: the legal line field is for exactly that. If you are in a regulated profession, check what your own rules require before trimming.

Using it in your mail client

  1. 1Fill in the fields; the preview updates as you type.
  2. 2Copy the HTML with the button, and paste it into your client’s signature editor in HTML mode. Outlook, Thunderbird and most webmail clients accept a pasted signature directly.
  3. 3Where a client offers only a rich-text box, paste the preview rather than the code: select the rendered signature above, copy, and paste into the box.
  4. 4Copy the plain-text version too, if your client keeps a separate one for plain-text mail.
  5. 5Send yourself a test message and read it on a phone as well as a desktop.

In Mailbind a signature is set per address, which matters if you answer from several: one for your own domain, one for a client’s, one for the old brand that still gets mail.

Privacy, concretely

This page has no server behind it. The signature is built in your browser from what you type, and nothing is sent to Mailbind or anyone else — you can watch the network tab while you type and see for yourself. There is nothing to store because there is no request.

That is not true of every tool on this site: the two DNS tools make a lookup, and the three AI tools send your text to an AI provider. Each of those pages says so in the same place at the bottom of the widget.

Common questions

Can I add my logo?

Deliberately not. Images in a signature are blocked by default in most clients, so a logo shows as a broken box or an empty space to a large share of your recipients.

Will it work in Outlook?

That is what the plain table and inline styles are for. Send yourself a test anyway: Outlook versions differ.

Is anything sent to Mailbind?

No. The tool runs entirely in your browser and this page makes no request while you use it.

Do I need an account?

No. Every tool here works without signing in, and none of them asks for your mailbox password — they work on a domain name or on text you paste.
