How do I add the signature to Gmail?

Open the preview on this page, select the signature and copy it, then paste it into Settings, See all settings, General, Signature. Pasting the rendered signature keeps its formatting; pasting the HTML code shows the tags.

Why a table and inline styles?

Outlook on Windows draws email with Word, which ignores most CSS that is not in a style attribute and lays out tables more reliably than anything else. A table with inline styles looks the same in Outlook, Gmail and Apple Mail.

Why is there no logo or photo?

An image in a signature has to be hosted somewhere and is blocked by many clients until the reader allows images, so the signature looks broken by default. A text signature always arrives intact.

Keeping a signature readable

Name, role and one or two ways to reach you; leave the rest to your website.
Text, not an image of text, so it arrives intact when images are blocked.
Links that say where they go: an email address, a phone number, a website.
