Tool ID: mailto-generator. Requested language: ja. Description language: en. Complete guide translation: no; untranslated sections use English.

## Overview (en)

The email mailto generator builds a mailto: link from a recipient, optional CC and BCC addresses, a subject and a message body. Each value is percent-encoded, with spaces written as %20 rather than plus signs, so email apps show the text correctly. Line breaks are allowed in the body but rejected in the recipient, CC, BCC and subject fields.

## Questions (en)

### How do I add a subject and body to a mailto link?

Enter the subject in the Subject setting and type the message in the main input. The generator adds them as subject and body parameters after the address, encoding spaces, line breaks and punctuation.

### Can a mailto link include CC and BCC recipients?

Yes. CC and BCC are optional settings that are added as cc and bcc parameters only when filled in. Like the recipient and subject, they cannot contain line breaks, which the tool reports as an error.

### Why are spaces encoded as %20 instead of a plus sign?

Standard form encoding turns spaces into plus signs, which some email programs display literally. The generator replaces them with %20, so the subject and body show normal spaces when the link opens a new message.
