Introduction to Mailto Links
The mailto link is a type of hyperlink that allows users to send an email to a specified address directly from a web page. When a user clicks on a mailto link, their default email client opens with the recipient’s email address prepopulated in the "To" field.
Prepopulating Email Content
In addition to specifying the recipient’s email address, you can also use mailto links to prepopulate other fields of an email message, such as the subject and body. This is achieved by adding query parameters to the mailto URL.
Specifying the Subject
To specify the subject of an email message using a mailto link, you add a subject parameter to the URL, followed by the desired subject text. For example:
<a href="mailto:[email protected]?subject=Hello from Example">Example</a>
Specifying the Body
To specify the body of an email message using a mailto link, you add a body parameter to the URL, followed by the desired body text. For example:
<a href="mailto:[email protected]?subject=Hello from Example&body=This is a test email">Example</a>
Adding CC and BCC Recipients
You can also use mailto links to specify CC (carbon copy) and BCC (blind carbon copy) recipients. To do this, you add cc and bcc parameters to the URL, followed by the desired recipient email addresses. For example:
<a href="mailto:[email protected]?subject=Hello from Example&body=This is a test email&[email protected]&[email protected]">Example</a>
Encoding Special Characters
When specifying email content using mailto links, it’s essential to encode special characters properly. This includes spaces, punctuation marks, and other non-alphanumeric characters.
To encode special characters, you can use the encodeURIComponent() function in JavaScript or a similar encoding function in your preferred programming language. For example:
const subject = "Hello from Example";
const encodedSubject = encodeURIComponent(subject);
Best Practices for Using Mailto Links
When using mailto links to prepopulate email content, keep the following best practices in mind:
- Always encode special characters properly to ensure that your links work correctly.
- Use descriptive text for your links to make it clear what users can expect when they click on them.
- Test your links thoroughly to ensure that they work as intended.
