Build a professional HTML email signature and copy it anywhere
Pasting into Gmail: Settings, see all settings, General tab, Signature section, create new, then paste into the editor. In Outlook: Settings, Mail, Compose and reply, then paste under Email signature. The generated HTML uses only inline styles, because email clients strip style blocks and most ignore modern CSS layout.
An email signature is the most-read thing most professionals write: it rides along on every message you send, quietly telling recipients who you are, what you do, and how to reach you. But hand-building one that survives email clients is genuinely painful, because Gmail, Outlook, and Apple Mail all strip out style blocks, ignore modern CSS, and mangle anything clever. This generator produces the one thing they all respect: simple table-based HTML where every rule is an inline style on the element it affects.
Three templates cover the common professional looks. Minimal is a single quiet block of name, title, and contact details. Classic adds a green accent rule and stacked links, closest to the traditional corporate footer. Two-column puts your identity on the left and contact details on the right, the layout consulting and sales teams favor. The preview updates as you type, and optional LinkedIn and X links appear only when filled in. No images are used, so nothing breaks when a client blocks remote content by default.
The Copy HTML button places the full markup on your clipboard, ready for signature settings in Gmail, Outlook, Apple Mail, or Thunderbird. One honest caveat applies to every signature generator: plain-text email and some corporate mail gateways discard HTML entirely, so make sure your name and phone number also appear in your message when contacting someone for the first time. For other professional text needs, the case converter and word counter are handy companions.
Email clients aggressively sanitize HTML. Gmail strips the head and style blocks entirely, Outlook uses its own rendering engine that ignores most modern CSS, and corporate mail servers often remove classes on principle. Inline style attributes on each element are the only styling approach that survives everywhere, which is exactly what this generator emits.
Copy the HTML, then in Gmail click the gear icon, See all settings, and on the General tab find the Signature section. Create a new signature, click into the editor, and paste. The formatting carries over because Gmail accepts rich paste. Save changes at the bottom, and assign the signature to new messages and replies.
In Outlook on the web, open Settings, then Mail, then Compose and reply, and paste into the Email signature box. In desktop Outlook, go to File, Options, Mail, Signatures, create a new signature, and paste. Keep the signature under the default length if your company enforces one, and remember to select it for new messages.
Images in signatures carry real costs: many clients block them by default, they bloat every reply chain, some spam filters score image-heavy mail negatively, and dark-mode clients can render logos oddly. This generator deliberately builds text-only signatures that always display. If you must have a logo, host it publicly and reference it by URL.
It is standard business practice, but consider what you send and to whom. If you mail mailing lists or strangers often, a phone number in every message becomes public over time. A common compromise is including the number in first-contact mail through your signature and removing it from the signature when posting to public lists.
