HTML email signature

An HTML email signature that renders everywhere — not just in your browser

Hand-coding an email signature is a fast way to get broken layouts. ProSignature generates clean, inline-styled HTML that survives Gmail, Outlook and Apple Mail.

Why email HTML is different

Email clients don't render HTML like browsers do. Gmail strips <style> blocks, Outlook uses Word's rendering engine, and external CSS is ignored. A signature that looks perfect in a browser can fall apart in an inbox.

ProSignature builds every signature with inline styles and email-safe markup — the technique professional email developers use — so your signature looks the same for every recipient.

Design visually, export clean code

You don't have to write a single tag. Design your signature in the editor, then either copy the generated HTML to paste wherever you like, or let ProSignature install it directly. What you get is tidy, portable, inline-styled HTML.

Inline styles only

No external CSS or style blocks that email clients strip out.

Table-based layout

Rock-solid alignment across Outlook, Gmail and Apple Mail.

Retina-ready images

Logos and photos stay crisp on high-density screens.

Portable code

Copy it into any tool, CRM or help-desk that accepts HTML.

Install it or take the code

Use the one-click installer for Gmail and Outlook, or copy the raw HTML for a CRM, help desk or custom setup. See example designs to start from.

FAQ

Frequently asked questions

Can I get the raw HTML of my signature?

Yes. After designing, you can copy the generated HTML and paste it anywhere that accepts an HTML signature — an email client, CRM or help-desk tool.

Why does my hand-coded signature break in Outlook?

Outlook renders HTML with Word's engine and ignores much modern CSS. ProSignature uses inline styles and table-based layout, which is what renders reliably in Outlook.

Are the images hosted for me?

Yes. Logos and photos you upload are hosted so they load correctly in recipients' inboxes without you managing image links.
