Case Study: 100K Fake Emails Blocked by CleanTalk
If you run a WordPress or WooCommerce site, WordPress fake signup protection isn’t just about convenience — fake email signups waste resources, distort analytics, and can even harm your domain reputation. According to CleanTalk’s historical stats, up to 30 % of registration spam comes from non-existent email addresses.
That means thousands of “users” who will never confirm their accounts, never receive notifications, and often trigger bounce-backs that make email servers suspicious of your site.
WordPress Fake Signup Protection — Real-Time Email Validation
CleanTalk’s Email Checker verifies email existence in real time — the moment a user types or submits a form. The updated feature Non-Existent Email Notification instantly alerts users if their email is invalid, reducing failed signups and improving UX.
If the address doesn’t exist or belongs to a disposable domain, CleanTalk blocks the signup before saving it to your database — no fake profiles, no clutter.
How It Works in WordPress & WooCommerce
Once you install the CleanTalk Anti-Spam plugin , verification runs automatically during:
- User registration (WordPress + WooCommerce forms)
- Contact form submissions
- Comments and product reviews
CleanTalk routes each submitted email to its cloud service, checks validity, and returns a pass or block decision in milliseconds.
In your Dashboard, blocked signups appear with status “Fake email”, letting you track spam attempts and patterns.
Real Case: 100K Fake Emails Blocked
Over time, CleanTalk has filtered massive volumes of fake email signups across WordPress websites — around 100,000 per month for large site networks.
Common examples include:
- no*****@*********in.biz
- te**@**********il.ru
- qw*******@**il.fake
Each could have filled your database with junk or hurt your deliverability.

For WooCommerce Store Owners
Fake accounts are even more damaging in e-Commerce. They:
-
Distort conversion and sales analytics
-
Trigger failed transactions and undelivered order emails
-
Lower sender reputation and email deliverability
With CleanTalk, every checkout form is validated in real time — only real customers complete orders.
Result: fewer errors, cleaner data, better performance.
Why It Matters
Fake signups lead to:
- Lost communication (no confirmation or password reset)
- CRM clutter and wrong email lists
- High bounce rates
- IP or domain blacklisting
