Frequently Asked Questions

Why do I need a professional email signature? +
A professional email signature increases brand recognition by 33% and makes your emails look more legitimate and trustworthy. It provides recipients with multiple ways to contact you, drives traffic to your website and social profiles, and ensures consistent branding across all company communications. Email signatures with clear contact information and branding increase response rates by up to 42%.
How do I add my signature to Gmail? +
To add your signature to Gmail: 1) Click the gear icon and select "See all settings", 2) Scroll to the "Signature" section, 3) Click "Create new" and name your signature, 4) Copy your HTML signature from our generator, 5) Paste it into the signature editor (Ctrl+V or Cmd+V), 6) Scroll down and click "Save Changes". Your signature will now appear in all new emails you compose.
How do I add my signature to Outlook? +
For Outlook desktop: 1) Go to File > Options > Mail > Signatures, 2) Click "New" to create a signature, 3) Copy your HTML signature and paste it into the editor, 4) Choose when to insert the signature (new messages and/or replies), 5) Click OK. For Outlook web: 1) Click Settings > View all Outlook settings, 2) Go to Mail > Compose and reply, 3) Paste your signature in the editor, 4) Click Save.
Should I include my photo in my email signature? +
Including a professional headshot in your email signature can increase trust and memorability by up to 32%. Photos humanize your emails and make them feel more personal. However, keep the image small (under 100KB), use a professional headshot with good lighting, and ensure it loads reliably. Some recipients have images disabled by default, so your signature should still look good without the photo.
What should I include in my email signature? +
A professional email signature should include: your full name, job title, company name, phone number, and email address. Optionally add your website URL, LinkedIn profile, and company logo. Avoid clutter—limit to 3-4 lines of text maximum. Include only essential contact methods. Don't add inspirational quotes, multiple social icons, or large images that slow email loading.
Can I use different signatures for different purposes? +
Yes, most email clients allow multiple signatures. Create separate signatures for different contexts: a formal signature for external clients, a simpler one for internal emails, and a promotional signature for marketing campaigns. In Gmail, you can create multiple signatures and manually select which to use. In Outlook, you can set different default signatures for new emails versus replies.
Why doesn't my HTML signature display correctly? +
Email clients have varying HTML support. To ensure compatibility: 1) Use inline CSS instead of external stylesheets, 2) Use tables for layout instead of divs, 3) Avoid JavaScript and advanced CSS (flexbox, grid), 4) Keep images under 100KB and use absolute URLs, 5) Test across Gmail, Outlook, Apple Mail, and mobile clients. Our generator creates signatures optimized for maximum compatibility.
Should I include social media icons? +
Include social media icons only if they're relevant to your role and you actively use those platforms. LinkedIn is almost always appropriate for B2B professionals. Twitter, Instagram, or other platforms depend on your industry. Limit to 2-3 icons maximum to avoid clutter. Use small, monochrome icons for a professional appearance. Always link icons to your actual profiles, not generic platform homepages.
