Email Signature with HTML

SignatureFox generates pure HTML using table-based layouts, not divs or CSS classes. Every style lives inline within the HTML tags themselves, which means email clients can't strip your formatting. Your images—logos, headshots, social icons—get embedded as base64 strings directly into the HTML file. No external image URLs. No broken images from blocked downloads. You receive your finished signature as an HTML file plus step-by-step install instructions for your specific email client. The entire process takes minutes.

Outlook 2010 through 2019 render email using the Word engine, not standard browsers. CSS floats, flexbox, and modern layout tricks don't work. Table-based HTML, on the other hand, works everywhere because email clients have supported tables since the 1990s. SignatureFox uses nested tables with fixed widths and inline padding to position your name, title, contact details, and logo exactly where you want them. This approach survives every filtering system, every email client version, and every corporate security policy that strips unsupported code. Your signature stays aligned. Your colors stay accurate. Your spacing doesn't collapse. Gmail, Apple Mail, Proton Mail, and Yahoo Mail all interpret table cells the same way, so what you see in your design preview matches what recipients see. Base64 embedding eliminates the other major failure point: broken image links. When your logo lives inside the HTML file itself as encoded image data, it never depends on external servers or permission settings. Recipient firewalls can't block it. Aging email systems can't fail to load it. The signature works at scale—whether someone receives your email on desktop, mobile, or in a corporate archive system five years from now.

Email clients strip most CSS because it poses security risks and conflicts with their own rendering engines. SignatureFox embeds all styling directly into HTML tags using inline style attributes. Font size, color, padding, borders, and background colors live right where they're applied. This method survives every email security filter and every client's CSS stripping policy. Table-based layouts with fixed dimensions give mobile clients something predictable to work with. Outlook on desktop displays your 600-pixel signature at full width. Gmail on mobile scales it proportionally. Apple Mail respects your spacing because tables have inherent structure. The HTML output avoids deprecated attributes and obsolete styling tricks, so your signature renders consistently whether it lands in a 2007 version of Outlook or tomorrow's email client. SignatureFox tests every signature across major platforms before delivery, confirming that alignment holds, colors display correctly, and images load without broken icons.
