Step 1: Click "Copy HTML" above to copy your signature code.
Step 2: Open Gmail → Settings (gear icon) → See all settings → General tab.
Step 3: Scroll to "Signature" → Create new → name it.
Step 4: In the signature editor, click the three dots menu and paste your HTML. Gmail supports pasting rich HTML directly. Click "Save Changes" at the bottom.

Desktop Outlook: File → Options → Mail → Signatures. Create a new signature, then paste the HTML file content. You may also open the downloaded .html file in a browser, select all (Ctrl+A), copy, and paste into the signature editor.
Outlook Web (OWA): Settings → Mail → Compose and reply → Email signature → paste the HTML directly (Outlook web supports rich formatting).

A professional email signature typically includes: full name, job title, company name, phone number, email address, website URL, and a professional headshot or company logo. Optional elements include social media links, a physical address, a call-to-action banner, disclaimers, or a scheduling link. Keep it concise — the best signatures are clean, informative, and mobile-friendly.

Mobile email clients often strip certain CSS styles and resize images. Our generated HTML uses table-based layouts with inline styles — the gold standard for email compatibility. However, for best mobile results: use images no wider than 320px, keep text concise, avoid complex layouts, and test across Gmail app, Apple Mail, and Outlook mobile to ensure consistency.

Images in email signatures must be hosted on a publicly accessible server (HTTPS recommended). When you upload an image in our builder, it's converted to a base64 data URI for the generated HTML — this embeds the image directly in the code so no external hosting is needed. However, some email clients (notably Outlook) may not render base64 images. For maximum compatibility, host your images on your company server or a CDN and use the URL option.

Absolutely! Most email clients support multiple signatures. In Gmail, you can create several signatures and assign them to different email aliases. In Outlook, the Signature settings allow you to set a default signature for each email account and even configure different signatures for new messages versus replies/forwards. Use our builder to create variations for different contexts.
