World Inspire Email Validation for Fluent Forms

When running marketing funnels, lead generation campaigns, or automated email onboarding sequences (e.g. FluentCRM, MailPoet, Brevo), invalid email addresses, throwaway mailboxes, and common user typos cause catastrophic bounce rates. Hard bounces permanently damage your domain sender reputation, land marketing broadcasts into spam folders, and trigger transactional rate-limiting from email service providers. World Inspire Email Validation for Fluent Forms hooks directly into Fluent Forms' core input validation layer (fluentform/validate_input_item_input_email) to intercept invalid, disposable, unroutable, and bounce-inducing emails at form submission time, before the entry is recorded or forwarded to marketing automations. 6-Layer Real-Time Defense Engine

1. RFC 5322 Syntax Verification: Native in-memory validation (<0.1ms).
2. Custom Domain Blacklist: Intercept abusive domains, competitors, or known bad actors.
3. Typo Auto-Suggestion: Detects common domain typos (gamil.com, outlok.com, hotmial.com) and suggests corrections.
4. Disposable & Temporary Mail Filtration: Real-time hash lookup across 8,700+ active temporary mail domains bundled offline in local JSON data.
5. Live DNS MX Verification: Direct DNS query (checkdnsrr) to ensure the destination mail server exists, cached via WordPress Transients for 24 hours.
6. Role-Based Account Filter: Optional filter for generic mailboxes (admin@, support@, billing@).
