Giggal Email Verifier

Giggal Email Verifier checks every email address submitted to your forms in real time and rejects the ones that cannot receive mail: undeliverable mailboxes, disposable services, mistyped domains, role accounts if you choose, and addresses you put on your own deny list.

What it does

• Catch-all domains get a real answer. Giggal verifies the mailbox behind a catch-all domain and reports Deliverable, Undeliverable or Unknown, so you decide on facts.
• Allow and deny lists. Trust a partner domain, block a spammer’s, and never spend a credit on either.
• Typo correction without the API. gmail.con, hotmal.com, yaho.com and friends are caught locally and the visitor sees “Did you mean name@gmail.com?”.
• Result cache. The same address submitted twice inside the cache window costs one credit, not two.
• Fail-open with evidence. If the API cannot answer, your forms keep working and the event is counted on the dashboard, so you know.
• Dashboard and logs from your own data. Checks per day by status, blocked vs allowed, credits used, most blocked domains, searchable logs with CSV export, retention and privacy switches (hash IP, mask email).
• Optional inline check. Verify as soon as the visitor leaves the email field, before they submit.
• Bulk verification. Paste a list or upload a CSV from the Tools page and download the results.

External service

This plugin sends email addresses submitted to protected forms to the Giggal API (host api.giggal.ai) to verify them, and reads your account’s credit balance from the same API. No other data is sent. A Giggal account and API key are required; each verified address costs one credit. Cached, allow-listed and mistyped addresses are free. Use of the service is subject to Giggal’s terms of service (https://giggal.ai/terms-of-service) and privacy policy (https://giggal.ai/privacy-policy).
