Mailto Link Generator

A Raycast extension that builds a mailto: link from a simple form with every field — To, Cc, Bcc, Subject and Body — then copies it or opens a draft.

Command

Generate Mailto Link — opens a form. As you type, a live preview of the generated link (and its length) is shown at the bottom.

Shortcut	Action
↵	Copy the raw mailto: link to the clipboard
⌘ ⇧ C	Copy as an HTML anchor — <a href="mailto:…">…</a>
⌘ O	Open a pre-filled draft in your default mail app
⌘ G	Open a pre-filled compose window in Gmail (browser)
⌘ ⇧ O	Open a pre-filled compose window in Outlook (browser)
⌃ X	Reset the form

All actions are also available via ⌘ K. The form opens empty by default — pre-filling is entirely opt-in via the preferences below. Recipients in To / Cc / Bcc can be separated by a comma, semicolon or new line. Addresses are validated leniently — obvious mistakes are flagged inline (on blur), but unusual-yet-valid addresses are not rejected.

Preferences

All optional. Set them in Raycast Settings → Extensions → Mailto Link Generator (or via the Configure Defaults… action). Out of the box they're all empty/off, so the form stays empty.

Preference	Effect
Remember last-used values	Off by default. When on, the form restores whatever you last entered.
Default Cc / Bcc	Pre-filled into a fresh form when set.
Signature	Appended to the body of a fresh form after a -- delimiter. Single-line; use \n for line breaks.
Outlook Account	Whether Open in Outlook targets outlook.office.com (work/school) or outlook.live.com (personal).

How it handles the tricky bits

mailto: links look trivial but have several well-known encoding pitfalls (RFC 6068). This extension takes care of them:

• Spaces are encoded as %20, never +. A literal + is ambiguous with sub-addressing (bill+ietf@example.org) and some clients turn + back into a space. We use encodeURIComponent, which emits %20 for spaces and %2B for real plus signs.
• Body line breaks become %0D%0A (CRLF). A textarea produces bare \n, so the body is normalised to \r\n before encoding, as the RFC requires.
• Reserved characters (?, &, %, …) are percent-encoded inside subject and body so they can't be mistaken for URI delimiters.
• @ is kept readable in the address list (a@b.com, not a%40b.com).
• HTML output escapes & to & in the href, and escapes the visible label, so the anchor is valid markup.
• Length is shown live. Very long links can be truncated by the OS mail handler — if a body is huge, prefer "Copy link" over "Open" so nothing is lost.
• Empty recipient is allowed. mailto:?subject=…&body=… is valid and useful for reusable templates; the form only blocks a completely empty link.

Development

npm install
npm run dev      # hot-reload in Raycast (requires the Raycast app)
npm run build    # type-check + bundle
npm run lint     # eslint

Node version: Raycast's tooling targets Node 22+. If npm run dev complains about your Node version, install Node 22 (e.g. nvm install 22 && nvm use 22).
