What makes a good email signature
An email signature is the block of contact details at the bottom of every email you send. People read it in a second, so the best ones are short: your name, your role, the company, one or two ways to reach you and a link to your website. Three to six lines is plenty. Everything else, from quotes to long lists of awards, pushes the useful part out of view.
This free email signature generator builds that block for you. You type your details once, choose a layout and get a signature that looks the same in Gmail, Outlook and Apple Mail. There is no account, no watermark and no server: the HTML is created in your browser and only goes where you paste it.
How to use the generator
- Fill in your details. Only the fields you fill in appear. Leave the mobile or department empty and the signature has no empty line or stray separator.
- Pick a template. Classic and Accent bar suit most business email. Modern photo and Banner CTA put a headshot or logo next to your name. Compact line fits replies and internal email. Minimal text has no images at all.
- Set the accent color and font. Fonts are limited to web-safe families such as Arial, Georgia and Verdana, because those are installed on almost every computer. A custom brand font would fall back to something random on the recipient side.
- Copy and paste. Copy signature puts formatted content on your clipboard, ready to paste into the signature settings of your email app. The tabs above walk you through Gmail, Outlook and Apple Mail step by step.
Gmail signature and Outlook signature tips
Gmail
Paste the signature in Settings, on the General tab. Gmail keeps tables, colors and links, but it does not let you upload an image file into the signature. Images have to come from a public URL, which is why the generator asks for an https link. Keep the total under the 10,000 character limit; every template here stays far below it.
Outlook
The new Outlook and Outlook on the web store signatures in the account settings. Classic Outlook for Windows uses Word to display email, which ignores modern CSS such as flexbox, grid and rounded corners. That is the reason this tool builds every signature from simple HTML tables with inline styles, width attributes and zero cell padding: it is the layout method Outlook handles reliably.
Apple Mail
Create a new signature in Mail settings, untick "Always match my default message font" and paste. If you skip the checkbox, Mail replaces your font and colors with its defaults.
Why logos and icons break in email
Most broken signatures come down to images. Email clients do not carry image files the way a website does. Each time someone opens your email, their app downloads the picture from the address in the signature. If that address points to a file on your laptop, a private drive or an http page, the recipient sees a broken box or nothing at all. Embedded base64 images are stripped by Gmail and flagged by some spam filters.
- Host your photo or logo on your own website or a public file link that starts with https://.
- Use a small file, ideally under 100 KB, and a width of 60 to 160 pixels.
- Expect some recipients to block images until they click "show images". Your name and contact details are text, so they always show.
Social icons have the same problem, plus a privacy one: icon images loaded from third-party servers can be blocked, and they tell those servers when your email was opened. This generator draws social links as small colored text badges built from table cells, so they show up even with images turned off.
Make your signature work harder
A signature is seen in every email you send, so it is a quiet but steady traffic source. Add a short call to action, such as a booking link or your latest guide, and tag the link with the free UTM builder so clicks from your signature show up as their own source in GA4. Keep the wording consistent with your social profiles; the LinkedIn bio generator helps you write a headline that matches your job title here.

FAQ
Is this email signature generator free?
Yes. There is no sign-up, no watermark and no limit on how many signatures you make. Everything runs in your browser, and your draft is saved only in your own browser so you can come back and edit it.
Why does my logo or photo not show in emails?
The image must be hosted at a public https address. Email clients download the image every time the email is opened, so a file from your computer, a private drive link or an embedded image will not show for recipients. Some people also block images until they click to show them, which is why your contact details stay as text.
How do I add an HTML signature to Gmail?
Click Copy signature, open Gmail settings with the gear icon, choose See all settings, and on the General tab click Create new under Signature. Paste into the box, set it as the default for new emails and replies, then click Save Changes at the bottom of the page.
Does the signature work in Outlook?
Yes. Every template uses HTML tables, inline styles and web-safe fonts, which classic Outlook for Windows, the new Outlook and Outlook on the web all display. The one difference is that classic Outlook ignores rounded corners, so a round photo appears square there.
Can I add social media icons to my signature?
Yes. Add LinkedIn, X, Instagram, Facebook, YouTube, TikTok or GitHub as a URL or a handle. They appear as small colored text badges instead of image icons, so they show even when images are blocked and nothing is loaded from other websites.
