A mailto link generator builds a valid mailto: link from a recipient, subject, body, CC and BCC, with the correct percent-encoding added for you. Paste the finished link into any HTML page, button, PDF, or email signature, and one click opens a pre-filled email. Use it for contact links, support emails, feedback messages, newsletter reply-tos, and one-click 'email us' buttons.
Fill the fields you need, watch the live preview, then copy the mailto: link or the ready HTML.
Compose your link
Fill what you need — everything else stays optional.
Take your mailto: link into the real world. A scan opens the same pre-filled draft — great for flyers, business cards, product tags, and event posters.
Updates as you type. PNG is 512×512 — perfect for print.

Four steps, all happening in your browser as you type.
Enter the recipient, subject, body, cc and bcc. Nothing leaves your device.
Spaces, emojis and line breaks become safe percent-codes automatically.
A valid mailto: URL and ready-to-paste HTML appear instantly.
Copy and paste anywhere — one click opens a pre-filled email for your visitors.
A mailto link is a hyperlink that opens the reader's default email app with a pre-filled draft.
It starts with mailto: instead of https:, followed by the email address. You can add a subject, body, CC and BCC, so the message is ready before the reader types a word. Nothing sends on its own. The email opens as a draft, and the reader presses send.
A mailto link generator writes the encoded link for you, so a wrong %20 or a missing & never breaks it.
Type your text in plain words, and the tool escapes spaces, line breaks and symbols into safe percent-codes. You get a live preview, a raw mailto: URL, and a ready HTML snippet you can paste straight into a page. The test button opens the draft in your own email app, so you can check the link before you ship it.
A mailto link fits any place a reader should reach you in one click.
Four things that make building a mailto link fast and safe.
Copy the ready HTML snippet or the raw mailto: link with a single click. No selecting, no missed characters.

$36 returned for every $1 spent on email — Litmus State of Email Marketing, 2020.
1,800+ spam messages reached an unprotected mailto: address in a 1.5-year test — Mühlemann, Address Munging Test.
Follow a real user journey: something breaks, and a single pre-filled mailto button turns frustration into a resolved issue — no forms, no logins, no friction.
A user lands on your page and hits a bug — the dashboard won't load.
They want to report it but hunting for a contact form or email feels like too much work.
Right there on the page — a glowing "Report a Bug" button. No forms, no sign-up.
Their email app opens with To, Subject, and Body already filled. Just hit Send.
The developer gets a complete bug report. The fix ships, and every user benefits.
That is the power of a pre-filled mailto link — build yours above
Pick a starting point, load it into the generator, and swap in your own address. Each template pre-fills a subject and body so the draft is ready to send.
The everyday "email us" link for a contact page, header, or footer. It opens a friendly, mostly empty draft so a visitor can write their own note in one click.
A structured bug report. The pre-filled prompts make users send the details you need on the first try, and the subject tag keeps tickets easy to sort.
Turns a "Talk to sales" button into a qualified lead. The starter questions collect company, team size, and timeline before the first reply.
A careers-page link that opens a ready application draft. It reminds candidates to attach a CV and share a portfolio link, so applications arrive complete.
A quick feedback link for docs, an app, or a blog post. The prompts guide readers to leave specific, useful comments instead of a blank message.
For service businesses. A "Book a time" link that gathers the date, time, and contact details you need to confirm an appointment.
Every link you build here can become a QR code — the same draft the button opens, ready for a flyer, a business card, a product tag, or a poster at your event.
A mailto: link only lives on a screen. A QR carries the same link into the physical world so a scan opens the exact pre-filled draft — no typing, no bad transcription, no "wait, what was the address again?"
Restaurant table cards ("Feedback on your meal"). Product packaging ("Question about your order"). Event posters ("RSVP by scan"). Business cards ("Book a call"). Support stickers on hardware ("Something wrong? Scan this").
Every download here uses medium error-correction (~15%) so the code still scans through a fingerprint or a paper crease. The PNG is a crisp 512×512, and the SVG scales to any print size without blur.
Keep the body short
Long bodies produce dense QRs. Keep the pre-filled body to a few short prompts; readers add detail on the phone.
Print at 2 cm or bigger
For flyers and business cards, keep the printed QR at least 2 × 2 cm (0.8 × 0.8 in). Bigger for posters seen from a distance.
Add a one-line label
A code with no context is skipped. Print a short label under it — "Scan to book a table," "Scan to report a problem" — so people know why.
Test before you print
Point your phone camera at the on-screen QR first. Every modern camera app reads mailto: QRs and offers to open your email app.
Build a link in the generator above, then download its QR from the same card.
Generate my QRSeven teams, seven predefined buttons. Each pattern turns a plain "email us" into a button that collects exactly what you need — read the full story or copy the setup.
A tool goes down, a page throws an error, a form quietly stops working — and the owner is the last to know. A pre-filled 'Report a problem' button turns confused visitors into an early-warning system for your dev team.
What it saves — Cut time-to-detection from hours to minutes
Shoppers with a quick question usually leave instead of hunting for a contact form — and you can't tell which product they meant. An 'Ask about this item' button that pre-fills the product name and SKU fixes both.
What it saves — Answer buyers fast, with the product and SKU attached
The customers most likely to cancel rarely tell you why — they just leave. A pre-filled 'Send feedback' button inside the app captures bugs and requests with account context attached, before frustration becomes a cancellation.
What it saves — Turn quiet frustration into a roadmap signal
A 'Start a project' button that pre-fills budget, timeline, and scope turns vague 'can you help?' emails into briefs you can actually quote — and filters out the tyre-kickers before the first reply.
What it saves — Qualify leads before the first reply
Replies are the strongest signal an inbox has, but they scatter and get lost. A reply link that tags each response by issue lifts engagement, protects deliverability, and files every reply automatically.
What it saves — More replies, sorted by issue automatically
Not every café, salon, or clinic wants a reservation system with a monthly fee. A 'Request a booking' button that pre-fills date, time, and contact details captures structured requests with nothing but a link.
What it saves — Structured bookings, no monthly fee
A mailto link has three parts: the mailto: scheme, the recipient address, and an optional list of fields. The field list starts with a question mark ? and joins each extra field with an ampersand &.
Every mailto link begins with mailto:, then the email address. There is no // like in https://.
For one recipient, put the address straight after mailto:.
For several people in the To field, separate the addresses with a comma.
Leave the address empty to open a draft with a blank To. This suits a "share by email" button, where the reader chooses who to send to.
Three characters divide a mailto link: ? starts the fields, & joins each extra field, and = links a field name to its value.
Add a subject line with the subject field after the ?. Encode spaces and punctuation, so ? becomes %3F.
Add a message with the body field, joined to the subject with &. A line break is %0A, so two line breaks (a blank line) are %0A%0A.
Copy other people with cc and bcc. Each field can hold several comma-separated addresses. CC shows the addresses to everyone; BCC hides them.
Combine every field in one link. The order after the ? does not matter, as long as ? comes first and & joins the rest.
URLs cannot hold raw spaces or many symbols, so they are percent-encoded. A space becomes %20 and a line break becomes %0A. A wrong code is the most common reason a mailto link breaks, so the generator encodes them for you.
URL-encoding cheat sheet
| Character | Encoded | Relative frequency in typical emails |
|---|---|---|
| space | %20 | |
| line break | %0A | |
| ! | %21 | |
| " | %22 | |
| # | %23 | |
| & | %26 | |
| ? | %3F | |
| @ | %40 | |
| % | %25 |
On a web page, put the mailto URL inside an anchor tag. The text between <a> and </a> is what visitors click.
The generator writes this exact snippet for you — copy the HTML box and paste it into your page.
Use a mailto link for a fast, personal reply when the reader has an email app. Use a web form when you need to capture data reliably or reach readers who use webmail.
Best practice: offer both. Add a mailto link for people who prefer their own email app, and show a visible email address or a form as a fallback for readers whose browser has no mail handler set.
Six habits that keep a mailto link working, private, and easy to read.
Encode every space, line break, and symbol before it goes in the link. A space is %20, a line break is %0A, and & is %26. One raw character can cut the link off early, so type in plain words and let the tool encode them.
A plain address on a public page gets harvested by spam bots. In a 1.5-year test of nine obfuscation methods, an unprotected address drew over 1,800 spam mails, while the best-hidden ones got zero. Obfuscate the address on public pages.
Put big lists in BCC, not CC or To. BCC hides every address, so no recipient sees the others and you never leak a contact list. Reserve CC for people who should be visible to the whole group.
Short subjects read better and survive small screens. Many mobile inboxes show only about 30 to 40 characters, so put the key words first. A clear subject like Bug report: checkout beats a long sentence.
Email clients handle mailto links a little differently. Test the link in Gmail, Outlook, and Apple Mail, and on a phone, before you publish. The Test the link button opens the draft so you can check spacing and line breaks.
Not every browser has a default mail app set, so a mailto link can do nothing on click. Show the plain email address as text as well, or add a web form, so no reader hits a dead end.
The standard, libraries, and studies this tool is built on — each one links to its primary source.
RFC 6068 is the IETF standard that defines the mailto: URI scheme. It sets the rules this tool follows: which header fields are allowed, how to percent-encode text as UTF-8, and how a client turns a mailto link into a real message. Build a link to RFC 6068 and any standards-based email client can read it. Read RFC 6068.
email-validator is a small, widely used npm package that checks whether an address is well formed. It validates the shape of the address, not whether the mailbox exists, and passes a million weekly downloads. Pair it with this generator to catch typos in the To field before you ship a link. View on npm.
mailto-link is an npm helper that builds a mailto: URL from a recipient, subject, body, cc and bcc in JavaScript. It applies the same encoding this tool does, in code, which helps when you generate links dynamically inside an app. View on npm.
react-mailto is a React component that renders a mailto link with subject, body, cc and bcc passed as props. It fits React apps where you want one reusable "email us" component instead of hand-writing the href each time. View on npm.
This 2022 study in the Journal of Research in Interactive Marketing found that emails built on data people volunteer themselves earn higher response rates than emails based on tracked behaviour. A mailto link is volunteered contact at its simplest: the reader chooses to write to you. Email also returns about $36 for every $1 spent, per Litmus, so making that first message easy is worth it. Read the study.
The W3C published WCAG 2.1 in June 2018, keeping the 61 success criteria from WCAG 2.0 and adding 17 more, with a focus on mobile, low vision, and cognitive needs. For mailto links, that means clear link text instead of a raw address, and showing the email as visible text so screen-reader and low-vision users can reach it. Read WCAG 2.1.
Research on email obfuscation shows that hiding an address from bots cuts spam sharply. In a 1.5-year field test of nine methods, an unprotected address received over 1,800 spam mails while the best-hidden addresses received none. Obfuscate any address you expose on a public page. See the experiment.
A mailto link generator is a web tool that builds a mailto: link from the fields you fill in. You type a recipient, subject, body, cc and bcc; the tool percent-encodes the text and returns a raw mailto: URL plus a ready HTML snippet. Copy either one and paste it into your page, button, or signature.
Mailto links work in every major email client, including Gmail, Outlook, Apple Mail, Yahoo Mail, and Thunderbird. On a phone, the link opens the default mail app. The link follows RFC 6068, so any standards-based client can read it.
Type the characters normally and let the generator encode them. Spaces become %20, line breaks become %0A, and symbols like ? and & become %3F and %26. Hand-typing these is the most common cause of a broken link, so the tool does it for you.
No. Mailto links cannot attach files. RFC 6068 and every mainstream email client block file paths in a mailto: URL for security reasons. Ask the reader to attach the file in their draft, or link to the file separately on your site.
Build one link, then swap the recipient for each address. To email several people from a single link, put commas between addresses in the To, CC, or BCC field, like mailto:[email protected],[email protected]. For large lists, use BCC so addresses stay private.
CC (Carbon Copy) shows every recipient to everyone on the email. BCC (Blind Carbon Copy) hides those addresses, so no recipient can see who else received the message. Use CC for open threads and BCC to protect a large or private list.
RFC 6068 sets no limit, but some older clients and browsers cap a mailto: URL at about 2,000 characters (roughly 2 KB). Keep the body short and let the reader write the rest, so the link opens reliably everywhere.
Press the Test the link button in the generator. It opens the draft in your own email app with the recipient, subject, and body already filled in. Check that spaces and line breaks look right, then paste the link into your page.
Yes. A mailto link only opens a draft in the reader's email app. Nothing sends until the reader presses send, and the link cannot run code or attach files. The one risk is spam bots harvesting a plain address, so obfuscate addresses on public pages.
Yes. Mailto links work with Gmail. On a phone, they open the Gmail app. On a desktop, set Gmail as the browser's default mail handler: in Chrome, click the handler icon in the address bar and allow Gmail, and the link will open a Gmail compose window.
In the block editor, select the text, click the link button, and type mailto:[email protected]. To add a subject or body, paste the full mailto: link from this generator, including the ?subject= and &body= parts. It works in the classic editor and most themes too.
Open File, Options, Mail, then Signatures. Select your text, click the link (hyperlink) button, and paste the full mailto: link into the address box. Save the signature. New messages will carry a clickable email link with your subject and body pre-filled.
