Email signatures

Create an email signature in Lightfield, or bring over the one you use in Gmail, Outlook or Apple Mail by pasting its HTML.

Lightfield attaches a signature to the emails you write and reply to from it. You can build one in the editor, or paste the HTML of the signature you already use and check it in Preview.

Every plan. Each person sets up their own signatures. Viewers don’t see Mail and Calendar, so they can’t add one.

  1. Go to Settings → Mail and Calendar and open the Signatures tab.
  2. Click Create new to build one, or Paste HTML to bring over an existing signature (see Find the HTML for your signature).
  3. Give it a name, then write the signature, or paste its HTML into Signature HTML. The Preview shows how it will look.
  4. Click Add signature. It shows under Your signatures.
  5. Under When to attach, choose the signature for New emails and for Replies. Choose No signature to send without one.

Your first signature is set for New emails automatically. Replies stays on No signature until you choose one, so pick a reply signature too if you want replies signed. Signatures you add later aren’t attached until you choose them under When to attach.

You can keep several signatures. Use a signature’s actions menu to Edit it or Delete signature. Deleting the one chosen for New emails or Replies sets that option back to No signature.

Use hosted images (a public web address) rather than embedded ones. Lightfield warns you when the HTML has embedded images, because some email apps don’t show them and large ones hurt deliverability.

Gmail has no “view HTML” option, so copy it from the signature editor with your browser’s Inspect tool:

  1. In Gmail, go to the gear icon → See all settings → General, and scroll to Signature.
  2. Right-click inside your signature and choose Inspect (Chrome or Edge) or Inspect Element (Firefox).
  3. In the developer tools, find the smallest element that wraps just your signature, not the whole settings page.
  4. Right-click that element and choose Copy → Copy outerHTML (Chrome or Edge) or Copy → Outer HTML (Firefox).
  5. Paste it into a plain text editor to check it before adding it to Lightfield.

Classic Outlook saves each signature as local files, including an .htm file with the full HTML:

  1. In File Explorer, turn on hidden items (View → Hidden items), since the AppData folder is hidden.
  2. Go to C:\Users\<your user name>\AppData\Roaming\Microsoft\Signatures.
  3. Find the .htm file with your signature’s name.
  4. Right-click it and choose Open with → Notepad (double-clicking opens it as a web page instead).
  5. Select all and copy.

The new Outlook for Windows stores signatures in the cloud. Use the Outlook on the web steps instead.

Outlook on the web (Outlook.com, Microsoft 365, new Outlook)

Section titled “Outlook on the web (Outlook.com, Microsoft 365, new Outlook)”
  1. Go to Settings → Mail → Compose and reply, where your signature is shown.
  2. Right-click inside the signature and choose Inspect or Inspect Element.
  3. Find the element that wraps your signature, right-click it and choose Copy → Copy outerHTML.
  4. Paste it into a text editor to check it.
  1. In Finder, press Cmd+Shift+G and go to ~/Library/Mail/V10/MailData/Signatures. The version number may differ (V9, V11 and so on). Sort by date modified to find the right folder.
  2. Find the .mailsignature file that matches when you last edited your signature.
  3. Right-click it and choose Open With → TextEdit.
  4. Copy everything from the opening <body> tag through the closing </body> tag.

Sequence emails use each sender’s own sequence signature, set in Settings → Sequences, unless that sender turns on Rich signature on connected accounts to use these Mail and Calendar signatures instead. See Sequences settings.

Check which signature is chosen for that kind of email. Go to Settings → Mail and Calendar → Signatures and, under When to attach, choose a signature for both New emails and Replies. Replies start on No signature, even after you create your first signature.

Sequence emails follow different rules; see Signatures in sequences.

The image in your HTML points to a local file or an email attachment rather than a public web address. This is common with Outlook.

  1. Find the image file (for Outlook, it’s next to the .htm file in the Signatures folder).
  2. Upload it somewhere public, such as your website, and copy the direct link to the image.
  3. In the HTML, replace the image’s src value with that link.
  4. Paste the updated HTML into Lightfield and send yourself a test email.

You see This signature is too large to save (1 MB total limit). Signatures are limited to 1 MB in total, and embedded images usually push them over. Replace embedded images with hosted image links, as in Images don’t show after pasting, then save again.

Why doesn’t my signature show on replies? Replies have their own setting. Under When to attach, choose a signature for Replies; it starts on No signature.

Which signature do sequence emails use? The sender’s sequence signature from Settings → Sequences. A sender who turns on Rich signature on connected accounts gets these New emails and Replies signatures instead.

Can I use my Gmail or Outlook signature? Yes. Copy its HTML using the steps above, click Paste HTML, and paste it into Signature HTML.

Can I have more than one signature? Yes. Keep several, and choose one for New emails and one for Replies.
