A professional email signature is more than a sign-off -- it is a micro-landing page that appears in every email you send. According to Newoldstamp's research, the average office worker sends 40 emails per day. That is 40 impressions of your personal brand, company, and contact information. A well-designed signature builds credibility, drives traffic to your website, and makes it easy for recipients to contact you through their preferred channel.

The 4 template styles

Email signature best practices

• Keep it concise -- include only essential information. Name, title, company, phone, email, and one or two social links is enough.
• Use web-safe fonts -- stick to Arial, Helvetica, Georgia, or Times New Roman. Custom fonts will not render in most email clients.
• Use a hosted photo -- link to an image on your website or a CDN. Attached images increase email size and may be blocked by recipients.
• Match your brand colors -- use your company's accent color for consistency across all team members' signatures.
• Do not include legal disclaimers in your signature unless legally required. They add clutter and nobody reads them.
• Test across clients -- send a test email to Gmail, Outlook, and Apple Mail to verify rendering.
• Keep image sizes small -- photos should be under 100KB and no larger than 100x100 pixels for signatures.

Why table-based HTML?

Email clients render HTML very differently from web browsers. Modern CSS features like flexbox, grid, and media queries are not supported in most email clients (especially Outlook, which uses Word's rendering engine). Table-based layouts with inline styles are the only reliable way to create signatures that look consistent across all clients. Our templates use this approach exclusively.
