Mailto links explained

A "mailto" link is a type of hyperlink in HTML that allows users to send an email to a specified email address when they click on the link. These links are typically used on websites to facilitate communication between the website's visitors and the site's owner or administrators. When a user clicks on a "mailto" link, their default email client (such as Outlook, Gmail, or Apple Mail) will open with a new email draft pre-filled with the recipient's email address, subject, and sometimes even the body of the email.

Here's a comprehensive explanation of "mailto" links and the various ways and features they can be used on a website:

1. Basic "mailto" Link: The most common use of a "mailto" link is to provide a simple way for users to send an email. Here's the basic HTML structure of a "mailto" link:

   <a href="mailto:[e-mail]">Send an Email</a>

In this example, when a user clicks on the "Send an Email" link, it will open their default email client with a new message addressed to "[e-mail]."

1. Specifying Subject and Body: You can pre-fill the subject and body of the email by adding them to the "mailto" link:

   <a href="mailto:[e-mail]?subject=Feedback&body=I have some feedback for your website">Send Feedback</a>

In this example, clicking the link will open an email with the subject "Feedback" and the body text "I have some feedback for your website."

1. Multiple Recipients: You can specify multiple email addresses as recipients by separating them with commas:

   <a href="mailto:[e-mail],[e-mail]">Email Multiple Recipients</a>

Clicking this link will open the email client with both "[e-mail]" and "[e-mail]" as recipients.

1. Adding CC and BCC Recipients: You can also include CC (Carbon Copy) and BCC (Blind Carbon Copy) recipients in the "mailto" link:

   <a href="mailto:[e-mail]?cc=[e-mail]&bcc=[e-mail]">Send Email</a>

This link will open an email with "[e-mail]" as the main recipient, "[e-mail]" as a CC recipient, and "[e-mail]" as a BCC recipient.

1. Adding Attachments: You can specify attachments using the "attach" parameter. Note that not all email clients support this feature:

   <a href="mailto:[e-mail]?attach=http://example.com/file.pdf">Send Attachment</a>

This link will open an email with an attachment, which is a PDF file located at "http://example.com/file.pdf."

1. Encoding Special Characters: To include special characters in the subject or body, you should URL-encode them. For example, use %20 for spaces and %0A for line breaks:

   <a href="mailto:[e-mail]?subject=Hello%20World&body=Line%201%0ALine%202">Special Characters</a>

This link will open an email with the subject "Hello World" and a body that contains two lines of text.

1. Customizing Link Text: You can customize the link text to make it more descriptive:

   <a href="mailto:[e-mail]" target="_blank">Click here to email us</a>

In this case, "Click here to email us" is the link text, and the "target" attribute is used to open the email client in a new browser tab or window.

1. Adding a Default Message: You can prefill a default message for the recipient to edit or send as is:

   <a href="mailto:[e-mail]?body=Hello,%20I%20hope%20you%20are%20well.%0A%0ASincerely,%20[Your%20Name]">Contact Us</a>

This link will open an email with a pre-filled message that the user can modify before sending.

1. HTML in the Body: You can include HTML tags in the body of the email to format the message:

   <a href="mailto:[e-mail]?body=<strong>Hello</strong>,%20I%20hope%20you%20are%20well.">Formatted Email</a>

In this example, the email body contains HTML tags to make "Hello" bold.

1. Hiding the Email Address:
   If you want to hide the email address from spam bots, you can use JavaScript to generate the "mailto" link dynamically. For example:
   

   <script type="text/javascript">
     document.write('<a href="mailto:' + ['e', 'x', 'a', 'm', 'p', 'l', 'e'].join('') + '@example.com">Email Us</a>');
   </script>
   

   This method obfuscates the email address, making it less susceptible to email harvesting by spammers.

Remember that not all users may have an email client set up, so it's a good practice to provide an alternative contact method (e.g., a contact form) alongside "mailto" links on your website. Additionally, be mindful of privacy concerns when using "mailto" links and respect users' preferences for communication.
