BillionVerify Email Validator Wordpress Plugin - Rating, Reviews, Demo & Download
Plugin Description
BillionVerify Email Validator checks email addresses in real time as your forms are submitted, stopping fake, mistyped, disposable and undeliverable emails before they reach your database. Cleaner signups mean fewer bounces, less spam and healthier email campaigns.
The plugin verifies each address against the BillionVerify API — performing syntax, MX and SMTP mailbox checks — and rejects the submission when the address matches a status you have chosen to block.
Key features
- Real-time verification during form submission (no front-end changes required).
- Detects valid, invalid, disposable, catch-all, role and risky addresses.
- Choose exactly which statuses block a submission — invalid only by default.
- Custom error message shown to visitors.
- Built-in connection test and single-email test tool in the admin.
- Result caching to save credits on repeated addresses.
- Fail-open by default: if the API is unreachable or credits run out, forms keep working.

- WordPress comment form
- WordPress lost-password form
- WooCommerce checkout and account registration
- Contact Form 7
- WPForms
