Tired of waiting for email verification codes?

Stop relying on outdated email verification methods. Email Validator for WHMCS validates email addresses instantly before registration using the third-party ZeroBounce API — with no verification emails, links, or codes required.

The Email Validator for WHMCS module improves the security and quality of client registrations by validating email addresses before account creation using the third-party ZeroBounce API. The module performs real-time email validation and blocks fake, disposable, or invalid email addresses from registering — ensuring only genuine emails enter your system.

Unlike traditional email verification methods that rely on sending confirmation emails or codes, this module works silently in the background with no user interaction required. This provides a smooth registration experience while still protecting your WHMCS installation from spam and abuse.

Admins have full control through the WHMCS admin area, including ZeroBounce API configuration, credit usage monitoring, and low-credit alert notifications. The result is a cleaner client database, reduced fraudulent signups, and improved operational efficiency.

Please Note (Important)

This module uses the third-party ZeroBounce API for email validation. ZeroBounce credits and billing are not included with this module and must be purchased directly from ZeroBounce.

Email validation accuracy, availability, and behavior depend entirely on the ZeroBounce service and available API credits. If the ZeroBounce API is unavailable or credits are exhausted, email validation will pause automatically, and user registrations will continue without validation.

There are no hidden charges in this module. All ZeroBounce-related costs are handled separately by ZeroBounce.

Frequently Asked Questions

• Q1: How is this different from email verification modules?

• Email verification requires users to confirm their email via links or codes. This module validates emails instantly using the third-party ZeroBounce service, with no user interaction.

• Q2: Are verification emails or codes sent to users?

• No. All validation is performed silently using the ZeroBounce API.

• Q3: What happens if the ZeroBounce API is unavailable or not responding?

• If the ZeroBounce API is temporarily unavailable, the module will not block user registrations. In this case, the registration will proceed normally, but email validation will be skipped until the API becomes available again.

• Q4: What happens when ZeroBounce credits reach zero?

• When ZeroBounce credits are exhausted, the module will automatically stop validating emails but will not block new registrations. Registrations will continue as normal until credits are replenished.

• Yes. Email alerts can be configured for low credit thresholds.

• Q6: Does this module affect existing users?

• No. Only new registrations are validated.
