Email Signature Generator

Email HTML is stuck roughly two decades behind web HTML, and Outlook is the reason: on Windows it renders messages with Microsoft Word’s engine, which ignores flexbox, grid, external stylesheets and most modern CSS. Tables with inline styles are the reliable common denominator. Avoiding images matters just as much — many clients block remote images by default, so an image-based signature arrives as an empty box or a red X, and attaching the image instead makes every message carry a pointless attachment. Keep it short, too: four or five lines reads as professional, while a wall of contact details and legal text reads as noise and gets quoted back on every reply.

The signature is a single-row HTML table with an optional coloured cell as the accent bar and a content cell holding the text blocks. Every style is written inline on the element it applies to, because mail clients strip <style> blocks.

The layout is text-only: there is no logo or profile-photo upload, and no banner or disclaimer block. Only one layout is offered, adjustable by colour, font and the optional accent bar. Some corporate mail systems strip or rewrite HTML signatures entirely, and a few clients ignore certain inline styles, so send yourself a test message before rolling it out.

A name, job title, company, email, phone, website and two social links produce a compact signature of roughly 1 KB with a blue accent bar, all links coloured to match.

1. Fill in the details you want to appear — blanks are simply left out.
2. Pick an accent colour and a font.
3. Copy the rendered preview and paste it into your mail client’s signature box.
4. Send yourself a test email to check how it arrives.

• Using an image for the whole signature, which blocks and breaks.
• Relying on modern CSS that Outlook silently ignores.
• Cramming in every social profile and a long legal disclaimer.
• Pasting the HTML code instead of the rendered preview into Gmail.

The Email Signature Generator builds a professional HTML signature from your details. The markup uses tables and inline styles with no images, which is the only approach that renders reliably across Gmail, Outlook, Apple Mail and mobile clients.

Freelancers, employees and small businesses who want a tidy, consistent signature without paying for a signature service.

• Table-based with inline styles — the only layout Outlook renders reliably.

• Phone and email become proper tel: and mailto: links.
• Your details are never uploaded or stored.

• Setting up a signature in Gmail or Outlook.
• Giving a small team one consistent signature format.
• Refreshing a signature after a job title or company change.
• Replacing an image-based signature that keeps breaking.
