Free email signature generator

1. Open Gmail in a desktop browser, click the gear icon at the top right, then See all settings.
2. Stay on the General tab and scroll down to Signature.
3. Click Create new, give it a name, and click Create.
4. Click into the signature box and paste with Ctrl+V (Cmd+V on a Mac). Your logo appears straight away because it is a hosted image, so you do not need Gmail's image button.
5. Under Signature defaults, pick the new signature for both new emails and replies.
6. Scroll to the bottom and click Save Changes.
7. Open a new message to check it. If Gmail says the signature is too long, you have pasted more than the signature: Gmail caps signatures at 10,000 characters. Clear the box, click Copy signature again and paste once.

Covers the New Outlook app on Windows and Outlook on the web. Both use the same settings panel.

1. Click the gear icon at the top right to open Settings.
2. Go to Accounts, then Signatures. On older web builds it is under Mail, then Compose and reply.
3. Click New signature and give it a name.
4. Click into the editor and paste with Ctrl+V.
5. Under Select default signatures, choose it for new messages and for replies and forwards, then click Save.
6. Send yourself a test email. If the logo arrived as an attachment, the paste picked up an embedded copy of the image: delete the signature, click Copy signature on the generator again and re-paste. Our images are hosted, so a clean paste keeps them as links, not attachments.
7. If the paste dropped the fonts or logo entirely, use the drag method: download the .htm file, open it in a browser tab, press Ctrl+A, then drag the selection into the Outlook signature editor. Drag keeps the formatting that Outlook's paste handler strips.

1. In Outlook, go to File, then Options, then Mail, and click the Signatures button.
2. Click New, give the signature a name, and click OK.
3. Click into the edit box and paste with Ctrl+V.
4. Set the default signature for new messages and for replies and forwards, then click OK.
5. Prefer the file route? Create the signature as above with any placeholder text and save it, then close Outlook. That first save is what makes Outlook generate its signature files.
6. Press Win+R, type %APPDATA%\Microsoft\Signatures and press Enter.
7. Rename the downloaded .htm file to match the signature name exactly, replace the existing .htm file in that folder, and reopen Outlook.

1. In the menu bar, click Outlook, then Settings (called Preferences on older versions).
2. Click Signatures.
3. Click the + button to add a signature and give it a name.
4. Click into the editor and paste with Cmd+V.
5. Close the editor window to save it.
6. Back in the Signatures list, use Choose default signature to set it for new messages and for replies and forwards.

1. Open Mail, click Mail in the menu bar, then Settings.
2. Click the Signatures tab and select the account you want the signature on.
3. Click the + button and give the signature a name.
4. Click into the signature box and paste with Cmd+V.
5. Untick Always match my default message font, otherwise Mail overrides the signature's fonts.
6. Use Choose Signature at the bottom of the panel to make it the default for that account.
7. Open a new message to check it. Mail only loads images from HTTPS addresses, which is what the generator uses, but the small preview in Settings does not always load them. The new message is the real test.

The built-in Mail app on iPhone strips most HTML when you save a signature. Logos and layout do not survive reliably, so treat this as a plain-text signature.

1. Open Settings, then Mail, then Signature.
2. Choose Per Account if you have more than one address.
3. Paste the plain-text version of your signature, or type your name, business, phone and website on separate lines.
4. Tap back to save. There is no save button.
5. Want the full signature with your logo on your phone? Send from the Gmail app or the Outlook app instead. In the Gmail app, go to Settings, your account, then Signature settings and leave Mobile Signature switched off so it uses your web signature. In the Outlook app, Settings then Signature holds its own signature, separate from the desktop one.

The Gmail app on Android only supports a plain-text mobile signature. It does not carry your logo or layout.

1. Set up the full signature in Gmail on a desktop browser first (see the Gmail tab). That signature goes out on every email you send from a computer.
2. In the Gmail app, tap the menu icon, then Settings, then your account.
3. Tap Mobile Signature.
4. Type a short plain-text version: name, business, phone and website on separate lines, then tap OK.
5. Using the Outlook app on Android? Its signature lives under Settings, then Signature, and is plain text as well.
