Understand why HTML signatures outperform plain text, how table-based layouts work, and how to create one without writing code.
An HTML email signature uses structured markup — tables and inline styles — to create a formatted, branded signature that looks consistent across email clients. Unlike plain text signatures, HTML signatures support logos, brand colors, clickable links, and precise formatting. They're the standard for professional business email.

Key benefits of adding an HTML signature to your email signature.
HTML signatures support structured layouts, typography, and spacing that make your contact information clear and easy to read. They look polished in a way plain text can't achieve.
Use your brand colors, fonts, and logo in every email. HTML signatures ensure every team member's email reinforces your brand identity consistently.
HTML lets you include clickable links, logos, social media icons, and call-to-action buttons. Recipients can visit your website, connect on LinkedIn, or call your number with a single click.
When built correctly with table-based layouts and inline styles, HTML signatures render consistently in Gmail, Outlook, Apple Mail, Thunderbird, and mobile email apps.
Best practices to get the most out of this feature.
Never use div-based layouts or CSS flexbox/grid in email signatures. Tables are the only layout method supported across all email clients, including Outlook's Word rendering engine.
Gmail and many other email clients strip <style> tags from emails. Every CSS property must be applied as an inline style attribute directly on the HTML element.
Email clients display signatures in constrained widths. Keeping your signature under 600px wide ensures it looks good on desktop and doesn't break on mobile devices.
Outlook desktop, Gmail web, Apple Mail, and mobile clients all render HTML differently. Always test your signature in the clients your recipients use most.
Common questions about an HTML signature in email signatures.
An HTML email signature uses structured HTML markup — specifically tables with inline CSS styles — to create a formatted, branded signature. Unlike plain text, it can include logos, brand colors, clickable links, and precise layouts that look consistent across email clients.
Plain text signatures can't include logos, brand colors, clickable links with custom text, or structured layouts. HTML signatures create a professional, branded impression in every email. They're the standard for business communication.
No. Tools like BrandFooter generate all the HTML for you automatically. You just fill in your details, customize the design visually, and copy the output. No coding knowledge required.
Yes, Gmail fully supports HTML signatures. The key constraint is that Gmail strips <style> tags, so all CSS must be inline — applied directly on each HTML element. BrandFooter generates signatures this way automatically.
Outlook desktop uses Microsoft Word to render HTML email, which doesn't support modern CSS properties like flexbox, grid, or many shorthand properties. Table-based layouts with inline styles are essential for Outlook compatibility — and exactly what BrandFooter produces.
The most common issues are: div-based layouts instead of tables, CSS in <style> tags instead of inline, images using HTTP instead of HTTPS, or CSS properties not supported by Outlook's Word engine (like border-radius or background-image). BrandFooter avoids all of these pitfalls by design.
