Answers to the most common questions about email signatures

An email signature is a block of text and/or images automatically appended to the end of your outgoing emails. It typically contains your name, job title, company, contact information, and often includes your company logo or profile photo.

Our signatures work with all major email clients: Microsoft Outlook (desktop, web, and mobile), Gmail, Apple Mail, Thunderbird, Yahoo Mail, Samsung Email, and more. We use table-based HTML layouts for maximum compatibility.

Our generator embeds images as Base64 data directly in the HTML, so images should always display without requiring external loading. If images still don't show, check that your email client hasn't stripped the HTML formatting.

Base64 embedding converts your images into text strings that are included directly in the HTML code. This means your profile photo and logo are part of the signature itself, not loaded from an external server. Recipients see your images immediately without having to "allow external images".

Open Outlook, go to File > Options > Mail > Signatures. Click "New" to create a new signature, paste the copied HTML code, give it a name, and click OK. Then select it as your default signature for new messages and replies.

Open Gmail, click the gear icon > See all settings > General tab. Scroll down to "Signature", click "Create new", give it a name, then paste the copied signature into the editor. Click "Save Changes" at the bottom.

Yes! Most email clients allow you to create multiple signatures and assign them to different email accounts. Create separate signatures for each account using our generator.

We recommend a square image of at least 200×200 pixels. The generator will resize it appropriately for the signature. Use a clear, professional headshot with good lighting and a neutral background.

Yes! The generator includes icons for LinkedIn, X (Twitter), Facebook, Instagram, Xing, GitHub, YouTube, and TikTok. Simply enter your profile URLs and the corresponding icons will appear in your signature.

Yes, all our templates are designed to look good on both desktop and mobile email clients. The preview mode lets you see exactly how your signature will appear on mobile devices.

Yes. The generator includes a disclaimer field where you can add confidentiality notices, legal disclaimers, or any other text that needs to appear below your signature. This is especially useful for business and legal communications.

Email clients support a limited set of web-safe fonts: Arial, Helvetica, Georgia, Times New Roman, Verdana, Tahoma, and Trebuchet MS. Our generator offers these fonts to ensure consistent display across all email clients.

Yes! Several of our templates support a banner image below your signature. This is perfect for promoting events, products, or seasonal campaigns. Recommended size: 600×100 pixels.

Simply return to the generator, make your changes, and copy the updated signature. Then replace the old signature in your email client's settings. We recommend bookmarking this page for easy access.

No. All processing happens locally in your browser. Your personal information, photos, and logos are never uploaded to any server. Your data stays on your device.

Yes! You can add a CTA button with custom text and URL – perfect for "Book a meeting", "Visit our website", or "Download our app" actions. The button is styled to match your signature's color scheme.

Outlook uses Microsoft Word's rendering engine for HTML, which has some limitations. Our templates are specifically designed to handle Outlook's quirks using table-based layouts and inline styles for maximum compatibility.

While technically possible, animated GIFs in email signatures are generally not recommended. Many email clients don't support animations, and they significantly increase the signature file size. Use a static, professional image instead.

The eco-friendly message adds a small note like "Please consider the environment before printing this email." to your signature. It shows environmental awareness and is commonly used in corporate email signatures.

Yes, the Email Signature Generator is completely free to use. There are no hidden costs, no registration required, and no limitations on the number of signatures you can create.

Create professional email signatures

The email signature generator helps you design a professional email signature with logo, contact details and social media icons – with no HTML knowledge required. A well-crafted signature acts like a digital business card beneath every message and strengthens the professional impression of individuals and entire teams alike. The tool produces clean, compatible code that you paste straight into your email client.

Common use cases

  • Consistent team branding: Give colleagues a consistent signature with the same logo, layout and color scheme.
  • Freelancers and the self-employed: Present your name, role, website and social profiles compactly beneath every email.
  • Campaigns and notices: Add a banner or call to action, for example for an event or promotion, without writing the code by hand.
  • Required legal details: Add the management, registration or VAT details that many businesses must include in their signature.

How to create your signature

  1. 1 Enter your name, position, company and contact details into the fields.
  2. 2 Upload a logo and add links to your social media profiles.
  3. 3 Choose a layout and adjust colors and fonts to match your branding.
  4. 4 Copy the finished signature into the settings of your email client.

Compatibility and best practices

The generator creates signatures that render reliably in common clients such as Outlook, Gmail, Apple Mail and Thunderbird. Keep the signature deliberately lean: a clear logo, a few lines of text and subtle icons look more professional than overloaded graphics. Since many emails are read on a phone, the tool focuses on a responsive layout that looks good on small screens too. Avoid large logo image files, since many clients block external graphics at first and only load them on request.
