GOOD QUESTIONS

Glad you asked.

A few things to know before your first list.

Can I really test it for free?

Yes. Create an account and get free verification credits. No card required. Test your own list before choosing a paid plan.

What does one credit get me?

One email verification. Verify a single address or run a bulk list and export the results. Choose a monthly plan or a one-time credit pack.

What happens to catch-all emails?

Catch-all domains accept mail for addresses that may not exist. We label them separately so you can review the risk before sending. They are not treated as confirmed valid mailboxes.

Does verification guarantee zero bounces?

No validator can guarantee delivery. Our stated verification accuracy is 99.7%+. Sender reputation, content, recipient policies, and mailbox changes can still affect delivery. Verify close to sending and keep catch-all results separate.

Can I use it with my software or AI agent?

Yes. Use the API to verify emails in your software, or MCP to make verification part of your AI agent’s workflow. Both use your MailboxVerifier account and credits.

How does People Finder work?

Enter a first name, last name, and company domain to find a work email. You can also search a domain for generic addresses such as sales, info, and hello.

LESS GUESSWORK. MORE GOOD EMAILS.
