To add a signature in Yahoo Mail, build it here and press Copy signature, then open Yahoo Mail’s Settings → More Settings → Writing email, switch the signature on for your account, paste into the box and the change saves on its own. Here is the full walk-through.

Step by step

  1. In the signature generator, fill in your details, pick a layout, and press Copy signature.
  2. In Yahoo Mail on the web, click the gear icon at the top right, then More Settings.
  3. Open the Writing email section and find Signature.
  4. Turn the signature on for your email address, then click into the box and paste (Ctrl+V or Cmd+V). Your formatted signature appears with working links.
  5. Yahoo saves the setting as you go, so there is no separate save button.

Send a test message to yourself to confirm it looks right.

If the image doesn’t appear

Yahoo links to your signature image rather than keeping a copy. The photo or logo needs to sit at a public web address, so host it on your site or a cloud drive with public sharing on, copy that link, and paste it into the Photo or logo URL field in the generator. Then copy and paste the signature once more.

On the Yahoo Mail app

The mobile app keeps its own signature, separate from the web, and it is usually plain text. For a formatted signature, rely on the web version, which travels with messages you send from a computer. There is more on this pattern in how to add a signature on iPhone.

Frequently asked questions

Does Yahoo Mail support a formatted signature with images and links?
Yes, on the web. Yahoo Mail's signature box accepts rich content, so a signature you copy from the generator pastes in with its formatting, links and hosted image intact. The mobile app is more limited and usually keeps plain text only.
Why does my Yahoo signature show a broken image?
Yahoo loads signature images from a web address rather than storing them. If the link points somewhere private or no longer valid, recipients see a broken icon. Host the image at a public URL, paste that link into the generator, then copy and paste the signature again.
Can I turn the signature off for replies?
Yahoo applies one signature per account and adds it to new messages and replies by default. There is a toggle to switch the signature on or off, but it is not split between new mail and replies the way some other clients allow.
