Installing your signature
Use "Copy signature" (which copies the rendered signature, not the code), then paste directly into Gmail (Settings → Signature), Outlook (Settings → Compose → Signatures) or Apple Mail. The copy-paste route preserves formatting in all three; the HTML source is available too for systems that accept raw HTML.
Keep it lean: name, role, company, one phone number, website — and skip inspirational quotes, large images and a dozen icons. Signatures over a few lines get clipped by Gmail and read as noise.
