Same verifier.
Your workflow.
Every page below is one concrete job: the situation, the steps in the app, and what you get back — a verdict with the reason, never a black box, and never an email sent to anyone on your list.
Stop sending discount codes to fake emails.
Verify newsletter and discount signups for your webshop — catch typos and throwaway addresses at capture, and clean the list before every campaign.
Block throwaway signups before they reach your product.
Screen new-user emails through the verification API at signup — reject dead addresses on the form and flag disposables before they burn onboarding emails and free-tier credits.
Upload a messy client CSV. Hand back only the safe rows.
Clean client lists before every campaign: upload the CSV, filter by verdict with a reason for every row, and export a deliverable-only list your client can trust.
Your open rate isn't falling. Your list is.
Subscriber lists decay as people change jobs and abandon inboxes. Clean your list before big sends — export only the rows that are safe to send.
Check a company's email before you quote.
An inquiry lands from a company you've never heard of. Paste the address, get a verdict with the reason in seconds — before anyone spends an hour on the offer.
Every ticket needs an inbox that exists.
Registration lists collect typos fast. Verify the list before tickets and badges go out, so confirmations reach real inboxes instead of bouncing.
