As a website owner, you’ve probably seen suspicious or nonsensical email addresses submitted through your lead capture forms. Are they genuine users or spammers? To protect your data and keep your inbox clean, you need email validation. In this tutorial, I’ll show you how to filter out fake addresses with simple HTML and JavaScript.
⚠️ The Problem
- Spammy Addresses: Domains that look suspicious or irrelevant.
- Temporary Emails: Disposable addresses used to bypass verification.
✅ The Solution: Implement Email Validation
By adding a regex pattern to your form, you can restrict submissions to trusted domains (e.g., Gmail, Yahoo, Outlook).
Regex Pattern Example:
^[a-zA-Z0-9._%+-]+@(gmail\.com|yahoo\.com|outlook\.com)$
📌 Step 1: Modify Your HTML Form
📌 Step 2: Add JavaScript Validation
📌 Step 3: Test Your Form
- Valid: john.doe@gmail.com, jane.smith@yahoo.com, jeanpaul@outlook.com
- Invalid: spammy@fakeemail.com, temporary@emailinator.com
