Why use our Signature Creator?

Unlike signatures that are just a single image (which often end up in the spam folder), our generator creates optimized HTML code. This ensures your contacts can click directly on your phone number, website, and WhatsApp.

  • Glassmorphism & Neon Design: Modern layouts that convey innovation and professionalism.
  • Color Intelligence: The system analyzes your logo and applies the exact color palette to icons and text.
  • Total Compatibility: Tested to work perfectly in Outlook, Gmail, Thunderbird, Apple Mail, and iPhone.
  • Social & WhatsApp Icons: Facilitate direct contact with smart links for WhatsApp Web.

How to Create Your Custom Email Signature?

Follow these simple steps to professionalize your communication:

  1. Upload Your Logo: The system will automatically identify your brand’s primary and secondary colors.
  2. Fill in Your Details: Enter your name, title, phone, and email. If desired, add WhatsApp to create a “quick chat” button.
  3. Choose a Template: We offer 4 exclusive layouts, including minimalist options and complete designs with icons.
  4. Download & Install: Click “Copy Signature” or download the HTML file. Then, simply paste it into your email provider’s signature settings.

Does the signature work in Outlook?

Yes. Our generator uses table-based HTML, which is the only way to ensure the signature doesn’t break and renders perfectly in both old and new versions of Microsoft Outlook.

Why shouldn't my email signature be just an image?

Signatures that are just a large image (“flat image”) do not allow copying text or clicking links, take longer to load on mobile devices, and drastically increase the chance of your email being marked as Spam or Promotion.

How do I add the signature to Gmail?

After generating your signature here, click the “Copy” button. In Gmail, go to Settings (gear icon) > See all settings > Signature. Create a new one and press Ctrl+V (Paste) in the text box.
