About
MillionVerifier checks email addresses through a web interface, bulk uploads, integrations and a REST API. Users can submit CSV, TXT or XLSX lists or import contacts from connected marketing systems. Results distinguish good, risky and bad addresses, supporting decisions about which records to retain before sending.

The API supports checks when new addresses are collected. The service also identifies temporary and role-based addresses and provides catch-all checking. Its EverClean service automates recurring checks of contacts in connected email marketing accounts, rather than requiring a fresh manual list upload each time.
Published integrations include Mailchimp, HubSpot, ActiveCampaign, Mailgun and MailerLite. Verification credits are sold on a pay-as-you-go basis and do not expire; the website offers 100 initial credits without a card. The provider publishes API documentation and a help centre. Verification results inform list management but are not a guarantee of inbox placement.
Accounts include access to EmailAcademy PRO’s deliverability training.
The former HuBuCo service now directs visitors to MillionVerifier.
