At Ecenica Hosting, we understand how frustrating it can be to deal with unwanted spam emails. Protecting your privacy and ensuring your online experience is safe and secure is a top priority for us. While no solution is perfect, there are several effective methods to obfuscate your email address in HTML, making it more challenging for spambots to harvest your information.
Why Obfuscate Your Email Address?
Email addresses posted in plain text on websites can be easily collected by bots, leading to an influx of spam. Obfuscating your email address is a technique used to hide it from these bots while still making it accessible to real users.
Methods to Obfuscate Your Email Address
1. HTML Character Entities
Convert your email address into HTML character entities. For example, the email example@example.com becomes:
example@example.com
The provided HTML code will render the following HTML:
example@example.com
For a clickable link:
<script type="text/javascript">
// Decode HTML character entities
function decodeHtmlEntities(encodedStr) {
let textarea = document.createElement('textarea');
textarea.innerHTML = encodedStr;
return textarea.value;
}
// HTML character entities for email
let encodedEmail = 'example@example.com';
let email = decodeHtmlEntities(encodedEmail);
// Write clickable mailto link
document.write('<a href="mailto:' + email + '">' + email + '</a>');
</script>
The provided JavaScript code will render the following HTML:
<a href="mailto:example@example.com">example@example.com</a>
2. JavaScript Encoding
Use JavaScript to dynamically display your email address. Here’s a simple script:
<script type="text/javascript">
let user = "example";
let domain = "example.com";
document.write('<a href="mailto:' + user + '@' + domain + '">' + user + '@' + domain + '</a>');
</script>
This technique requires the bot to execute JavaScript, which many do not.
The above code will render the following HTML:
<a href="mailto:example@example.com">example@example.com</a>
3. ROT13 Encoding
ROT13 is a simple encoding method that shifts characters. You can use JavaScript to decode and display your email:
<script type="text/javascript">
function rot13(str) {
return str.replace(/[a-zA-Z]/g, function(c) {
return String.fromCharCode((c <= "Z" ? 90 : 122) >= (c = c.charCodeAt(0) + 13) ? c : c - 26);
});
}
let email = rot13("rknzcyr@rknzcyr.pbz");
document.write('<a href="mailto:' + email + '">' + email + '</a>');
</script>
The above code will render the following HTML:
<a href="mailto:example@example.com">example@example.com</a>
4. CSS
Separate the email address into different HTML elements:
<span class="user">example</span><span class="at-symbol">@</span><span class="domain">example.com</span>
<style>
.user, .at-symbol, .domain {
display: inline;
}
</style>
This method makes it difficult for bots to piece together the full email address.
The above code will render the following HTML:
example@example.com
5. Image Replacement
Replace your email address with an image displaying the address:
<img src="email.png" alt="Contact Us">
This approach prevents bots from reading the text altogether.
- Base64 Encoding
Encode your email in Base64 and use JavaScript to decode it:
<script type="text/javascript">
function decodeBase64(encoded) {
return decodeURIComponent(atob(encoded).split('').map(function(c) {
return '%' + ('00' + c.charCodeAt(0).toString(16)).slice(-2);
}).join(''));
}
let encoded = "ZXhhbXBsZUBleGFtcGxlLmNvbQ==";
let email = decodeBase64(encoded);
document.write('<a href="mailto:' + email + '">' + email + '</a>');
</script>
The above code will render the following HTML:
<a href="mailto:example@example.com">example@example.com</a>
