The short answer.
An email signature generator turns your name, title, company, phone, website and social links into a clean HTML signature. Fill in the fields, pick a style and accent colour, then copy the signature and paste it into Gmail, Outlook or Apple Mail settings. It's free, needs no signup, and nothing is stored.
What a good signature includes
Your name, role, company, one phone number, website and one or two social links. That's it. Add a WhatsApp click-to-chat link: it's the fastest reply channel in India and the Gulf. Skip big images, quotes and legal essays; they trigger spam filters and look messy on mobile.
How to install it
Gmail: Settings → See all settings → Signature → paste. Outlook: Settings → Mail → Compose and reply → paste. Apple Mail: Preferences → Signatures. Paste the copied (rendered) signature, not the raw HTML, unless your client asks for HTML.
