What does Verifi do?

Verifi is a straightforward email validation API that checks whether an email address is real and deliverable. It runs a series of checks — syntax, domain existence, MX records, and mailbox verification — to catch invalid, disposable, or risky addresses before they hit your system. The result is a simple yes/no on deliverability, along with flags for disposable and free email providers. It's a no-nonsense tool for anyone who sends email and wants to keep bounce rates low.

The API is built for speed and reliability. You send a GET request with an email address, and get a JSON response in milliseconds. The page shows a demo using curl, and the response includes fields like valid, validMxRecord, spoofFree, disposable, and deliverable. Verifi also offers a dashboard for tracking validation history and analytics. The feature set is focused: accurate validation, real-time verification, and detailed results. Nothing flashy, but it does the job well — it's a workhorse for email hygiene.

Verifi is best for developers who need to integrate email validation into signup forms, CRM systems, or marketing platforms. It's also useful for email marketers and e-commerce businesses that maintain large subscriber lists and want to protect their sender reputation. The free tier gives 100 validations per month, which is enough for testing. Paid plans scale up to 25,000 validations monthly, with extra validation bundles available at $4 per 1,000.
