Stop Spam: How to Validate Email Addresses on Your Website

As a website owner, you’re likely familiar with the constant influx of email addresses from your lead capture page. 

But here’s the challenge: some of these addresses appear suspicious or downright nonsensical. 

Are they from spammers or genuine users? 

It’s time to take control and prevent unwanted submissions.

The Problem

1. Spammy Addresses: Many submissions come from email domains that raise eyebrows. These could be spammers attempting to infiltrate your system.

2. Temporary Emails: Some users employ temporary email addresses to claim offers without revealing their real identity.

The Solution: Implement Email Validation

By adding a simple code snippet, you can enforce a pattern for email addresses. Users must match this pattern before their form submissions are accepted.

Let’s break down the process step by step:

1. Choose a Pattern for Valid Email Addresses

Decide on a pattern that aligns with your desired email domains. For this example, we’ll focus on Gmail, Yahoo, and Outlook addresses. 

Here’s the modified regex pattern:

^[a-zA-Z0-9._%+-]+@(gmail\.com|yahoo\.com|outlook\.com)$

2. Modify Your HTML Form

In your HTML form, add an input field for email addresses. Set its type attribute to “email”:

<form onsubmit="return validateEmail()">

    <label for="email">Email:</label>

    <input type="email" id="email" name="email" required>

    <button type="submit">Submit</button>

</form>

3. Add Validation Code (JavaScript)

Use JavaScript to validate the email address. Here’s a sample snippet:

<script>

    function validateEmail() {

        const emailInput = document.getElementById('email');

        const emailPattern = /^[a-zA-Z0-9._%+-]+@(gmail\.com|yahoo\.com|outlook\.com)$/;



        const email = emailInput.value.trim();

        if (emailPattern.test(email)) {

            // Valid email address

            return true;

        } else {

            // Invalid email address

            alert('Please enter a valid Gmail, Yahoo, or Outlook email address.');

            return false;

        }

    }

</script>

Try submitting your form with various email addresses. Ensure that only valid ones pass. For instance:

• Valid: john.doe.test1@gmail.com, jane.smith.test1@yahoo.com, jeanpaul.test@outlook.com
• Invalid: spammy.test1@fakeemail.com, temporary.test1@emailinator.com

The code snippet provided here is intended for educational purposes and as a starting point for understanding email validation techniques. It is not a one-size-fits-all solution, and I strongly recommend that you customize and adapt it to your specific use case. Before implementing any code on your website, consider the following:

• Understand the Code: Take the time to comprehend how the code works. Don’t blindly copy and paste it without understanding its logic.
• Professional Implementation: While this snippet demonstrates a basic approach, consult a professional developer to ensure proper integration into your site. They can address any nuances related to your platform, security, and scalability.
• Risk of Breaking Your Site: Incorrect implementation can lead to issues like false rejections of valid emails or acceptance of invalid ones. Use with caution and thoroughly test in a staging environment before deploying it on your live site.

Remember that every website has unique requirements, and what works well for one may not suit another. Always prioritize security, user experience, and reliability when implementing any code.
