Frequently asked questions

Is Mailthentic worth it over a cheaper tool like MillionVerifier?

If you only need a valid or invalid verdict, budget tools work. Mailthentic adds SPF, DKIM and DMARC checks, domain health scoring and CRM integrations, which protect inbox placement and save time for teams that send real campaigns.

Does Mailthentic detect catch-all and disposable addresses?

Yes. The 9-point engine flags catch-all domains, disposable addresses and role accounts, with greylisting retry for mailboxes that defer the first attempt.

Can I import a list I verified elsewhere?

Yes. Upload any CSV to re-verify with full DNS checks, or connect your CRM to verify contacts in place.
