Is your customer database polluted with fake accounts?
Bots, fake signups, disposable emails, and free-product hunters quietly poison your customer data, deliverability, and analytics. It's time to verify every customer touchpoint.
Without CEV PRO
- Bot Signups & Fake Accounts
Spambots create accounts in seconds. Your user database fills with garbage that breaks analytics and bounces emails.
- Free Product Abusers
Fake emails sign up for free trials, free products, and promotional offers repeatedly. Real customers never see them.
- Disposable Email Flood
Mailinator, GuerrillaMail, 10minutemail — temporary email providers let abusers create unlimited fake accounts.
- Unauthorized Logins
Stolen credentials from data breaches give attackers access to real customer accounts. No second layer of security.
With CEV PRO
- OTP Email Verification
Every signup, checkout, and suspicious login requires a one-time password sent to a real email address. Bots and fakes blocked at the door.
- Disposable Email Blocking
3,000+ bundled blocklist of disposable email providers, plus custom rules. Fake-email signups stopped instantly.
- 2FA Authentication
Add Google Authenticator, Authy, or Microsoft Authenticator as a second layer for sensitive operations — globally or per role.
- Auto-Cleanup Engine
Daily cron jobs automatically remove stale unverified accounts and clean up your customer database — with built-in safeguards.
Verify Every Customer Touchpoint in 4 Steps
Trigger Verification
At signup, checkout, or suspicious login, CEV PRO sends a 6-digit OTP to the customer's email. The action pauses until they verify.
Validate the Email
Behind the scenes, CEV checks disposable email blocklists, runs DNS-based MX record validation, and verifies the address is reachable.
Customer Verifies
Customer enters the OTP code in the verification popup. If 2FA is enabled, they also confirm via Authenticator App. Verified.
Auto-Cleanup Unverified
Daily cron jobs handle the rest — re-engage lapsed signups with reminder emails, auto-delete stale accounts (with safeguards).
Everything You Need to Verify, Secure, and Clean Up
From OTP verification to 2FA, disposable email blocking to DNS validation — the complete email security toolkit for WooCommerce.
OTP-Based Email Verification
Send a one-time password to the customer's email at every critical touchpoint — signup, checkout, login from new device, or after inactivity. Real emails verified; bots and fakes blocked at the door.
- 6-digit OTP via email (no third-party services required)
- Verification at signup, checkout, and login
- Configurable expiry time
- Resend OTP option for failed deliveries
- No coding required — works out of the box
- Fully customizable email content
Two-Factor Authentication (2FA)
Add Google Authenticator, Authy, or Microsoft Authenticator as a second layer of security for customer logins. Block credential-stuffing attacks even when passwords are compromised in data breaches.
- Google Authenticator support
- Authy & Microsoft Authenticator support
- Works with any TOTP-compatible app
- QR-code setup for customers
- Optional or required per user role
- Backup codes for account recovery

- Total signups + verified vs unverified breakdown

Disposable Email Blocking
Block signups from temporary email providers (Mailinator, GuerrillaMail, 10MinuteMail, and 3,000+ more). Bundled blocklist updates regularly. Add your own custom-blocked domains and customize the rejection message.
- 3,000+ bundled disposable email domains
- Admin-defined custom block list
- Catches signups before they're created
- Eliminates a major spam vector
DNS-Based MX Record Validation
Before sending an OTP, CEV PRO validates that the email domain actually has working mail servers (MX records). Catches typos, fake domains, and non-existent providers — saves you SMS costs and reduces bounces.
- Real-time MX record DNS lookup
- Catches typos (gmail.con, yaho.com)
- Blocks fake/non-existent domains
- Improves email deliverability reputation
B2B Allowlist & Block Specific Addresses
Run a B2B store or restricted-access community? Allow only specific domains to register (e.g., partner.com, customer.org). Or block specific email addresses that have abused your store before.
- B2B Allowlist mode
- Block specific email addresses
- Per-domain or per-address rules
- Perfect for partner-only stores
Automatic Database Cleanup
Daily cron jobs automatically remove stale unverified records and auto-delete unverified WP user accounts — with safeguards. Never pay for storage or send emails to unreal customers again.
- Auto-delete unverified user accounts
- Hard 30-day minimum retention safeguard
- Skips users with orders/subscriptions
- Preview accounts before deletion
Re-engagement Reminder Emails
Don't lose lapsed signups. Automatically email unverified users at 1-hour, 24-hour, 3-day, and 7-day intervals with a one-click verification link. Fully customizable via the email customizer.
- Auto-send reminders at 1h / 24h / 3d / 7d intervals
- One-click verification link in email
- Bulk send from Unverified Users table
- Recover up to 30%+ of lapsed signups
Fully Customizable Verification Popup

- Color and layout customization
- Custom logo upload
- Multi-language support
- Live preview while editing
