Free HTML Email Signature Template

Checked by TNT Review — 5 October 2026. The template was checked for the specific things that make an email signature render reliably across clients: table-based layout, inline styles only, no flexbox/grid — all confirmed. See Verification.

The problem

A signature that looks perfect in your browser can arrive broken in someone else’s inbox — email clients render HTML very differently from browsers, and modern CSS layout (flexbox, grid, even a plain <style> block in some clients) is unreliably supported or stripped outright.

Expected outcome

By the end of this guide you will have a signature built the way email clients actually expect — a table layout with inline styles — so it looks the same whether it’s opened in Gmail, Outlook, or Apple Mail.

Requirements and costs

Any web browser to open and copy the template.
Cost: free.

Step-by-step implementation

Download the template from the link below.
Open signature.html in a browser.
Fill in every [bracketed] placeholder — name, title, company, email, phone, website — directly in the rendered page (or edit the HTML source, then reload).
Select the rendered signature (not the HTML source) and copy it.
Paste it into your email client’s signature settings — Gmail: Settings → General → Signature; Outlook: File → Options → Mail → Signatures.

A real example

Filled in, the signature shows your name and title on the left, separated by a vertical line from your company, email, phone and website on the right — each contact detail is also a real clickable link (mailto: for email, tel: for phone), not just styled text.

Verification and troubleshooting

What we actually checked: the template uses a <table> for layout (not flexbox or grid), every style is applied inline rather than through a <style> block (which several major email clients strip), and it includes real mailto: and tel: links — all 5 checks confirmed. This is a structural check of the HTML; we did not send a test email through every major client to visually confirm rendering.

Troubleshooting:

Pasting into Gmail loses the formatting. Make sure you copied the RENDERED signature (open the HTML file in a browser, select the visible text), not the raw HTML source — pasting raw HTML text just inserts it as plain text.
The vertical line between the two columns disappears in some clients. A small number of email clients strip border styles on table cells; this is a known limitation of HTML email generally, not specific to this template.
You want to add a logo image. Use a fully-qualified https:// image URL hosted somewhere permanent — email clients can’t load a local file path, and many block images by default until the recipient clicks “show images.”

Free vs. paid

This is free and complete for a simple two-column signature. Paid signature-management tools add centralized deployment across a whole team’s email clients and built-in analytics — useful for an organization managing dozens of signatures, not necessary for your own.

Is there a paid version?

Not yet. This is the complete method. TNT Review has sold nothing to date and has no checkout, so any price we discuss in future should be read as a hypothesis, not an offer.
