Free Email Signature Generator: HTML Signatures for Gmail, Outlook & Apple Mail

Choose from 11 email signature templates

Each template is a different layout rather than a recolor. Modern puts your photo on the left with a divider, Classic uses an accent rule, Compact squeezes everything into a few lines for quick replies, Corporate leads with the company logo, Creative uses a tinted card, Minimal is two clean lines of text, Centered suits badge-style layouts, Bold header adds a colored name band, Split moves the photo to the right, Sidebar uses a solid color panel and Two column separates identity from contact details. The gallery renders every template with your own details, so you compare real results instead of stock screenshots.

Photos, logos and banners that actually show up

You can upload a headshot, logo or promo banner, or paste a link. Uploaded images are cropped or resized in your browser and embedded in the signature, which works well in Outlook and Apple Mail. Gmail, however, does not display embedded images in signatures, so for Gmail host the image at a public https link (your website, a CDN or an image host) and paste that URL instead. The health check tells you when an image is embedded or uses insecure http. If you have no photo, switch on the initials badge and the signature shows your initials in your brand color. Upload images at about twice the display size so they stay sharp on high-resolution screens.

Social links by handle, in the style you want

Add LinkedIn, X, Instagram, Facebook, YouTube, GitHub, WhatsApp, TikTok, Telegram, Behance, Dribbble, Medium, Pinterest, Threads or a custom link. Type a handle like @yourname and the correct profile URL is built for you; a WhatsApp number becomes a wa.me chat link. Show them as square, rounded or round badges, as labeled pills or as plain text links, in each network's brand color, your own brand color or a neutral dark. Because the badges use short text instead of image icons, they never get blocked or turn into broken pictures, which is the most common reason signature icons disappear in recipients' inboxes.

Add a call-to-action button and legal disclaimer

A signature appears on every email you send, which makes it useful space for one clear action: book a call, view your portfolio, download a brochure. Add a button label and link and pick a solid, outline or plain link style. The button text color is chosen automatically for readable contrast against your brand color. For legal text, start from a confidentiality, GDPR, environmental or virus-free preset and edit it, then keep it short because long disclaimers are rarely read and push the signature past Gmail's size limit.

Signature health check before you paste

The health panel scores your signature out of 100 and lists what to fix. It flags invalid email addresses and short phone numbers, text and brand colors with too little contrast on white, embedded or http images, a banner without a link, a button without a URL and too many social links. It also counts the characters of HTML against Gmail's 10,000 character signature limit, which is the usual cause of a signature that refuses to save or loses its formatting.

Team and bulk signatures from a spreadsheet

Rolling out signatures to a whole company usually means copying one template by hand for every person. Team mode removes that. Paste a spreadsheet with a header row (name, title, department, email, phone, mobile and any social columns) and every person gets a signature that inherits your template, colors, logo, banner and disclaimer. Copy each one, download them individually, download all of them in a single HTML file, or export a CSV that includes a ready-made HTML column for importing into an admin console or mail merge.

How to add your signature to Gmail, Outlook and Apple Mail

Click Copy signature, then open your mail settings. In Gmail, go to Settings, See all settings, General, then Signature, create a new signature and paste it. In Outlook for Windows, open File, Options, Mail, Signatures, then New and paste. In Outlook on the web, open Settings, Accounts, Signatures. In Apple Mail, open Settings, Signatures, add one, untick Always match my default message font and paste. The Install guides tab lists exact steps for each client, plus Thunderbird, Yahoo and mobile apps. If formatting looks wrong after pasting, paste again or use Copy HTML in apps that accept HTML source.

Email signature best practices

Keep it short: name, role, company and one or two ways to reach you. Use one font and two or three colors, and stay with web-safe fonts such as Arial, Georgia or Verdana because custom fonts fall back to defaults on most recipients' machines. Limit social links to the networks you actually use for work, keep the whole signature narrower than about 500 pixels so it fits on phones, and avoid large images. Skip inspirational quotes and long legal text unless required. Review the signature on mobile width in the preview, and re-run the health check whenever you change the logo, banner or disclaimer.

Privacy: your details stay on your device

The signature is generated entirely in your browser. Your name, phone number, email, photos and links are never sent to a server. Your work is saved in your browser's local storage so you can come back to it, and you can save several signatures, duplicate one for a colleague, and export or import them as JSON files. Clear your browser data to remove everything.
