Description

MillionVerifier is an email verification service for single checks, list cleaning, a bulk verifier, a real-time API and ESP imports. Official pages claim more than 99% verification accuracy, say you only pay for results marked good or bad (not risky, unknown or catch-all), and advertise a 100% money-back guarantee if, after verification, your hard-bounce rate on qualifying addresses is above 4%. Those accuracy and “only verifier” claims are the vendor’s own. The Terms, published 19 October 2026, set out detailed guarantee conditions, so do not take the marketing line “no small print” at face value.

Public prices were checked on 15 November 2026 (Europe/London) from the official homepage pricing slider, the “all credit packages” table and the site’s published price list. A free account includes 100 credits, with no credit card required. Paid credit packs start at $39 for 10,000 credits. Official copy says paid credits do not expire. The official rate card is pay-as-you-go credit packs from $39, with no public monthly subscription. Official Terms name Southern Vector Limited, a New Zealand company, as the service provider, and say it acquired the MillionVerifier business from a Hungarian company. The Terms are governed by New Zealand law, with the courts of New Zealand having exclusive jurisdiction. For a fuller look, read our MillionVerifier review 2026.

Who It’s For

• Email marketers and agencies cleaning an older list, or importing contacts from an ESP, before a campaign.
• Outbound and lead-generation teams that want a credit pack they can buy once, with official wording that paid credits do not expire, rather than a monthly seat.
• Developers and product teams adding a real-time email check to a form or app through the official API, including typo suggestions for large providers.
• Teams already in Mailchimp, HubSpot, MailerLite and similar tools who want a one-click import, or the vendor’s EverClean weekly clean-up, rather than another CSV export.
• Skip or use with care if you need an independently audited accuracy figure, you were expecting a simple monthly subscription (the public rate card is pay-as-you-go credits), or you would rely on a refund without reading the guarantee conditions in the Terms.

Core Capabilities

• Single, list, bulk and API verification. Official services cover a free real-time email checker, CSV/TXT/XLSX list verification, a bulk verifier for large files, and an API. Official accuracy-page steps include duplicate removal, syntax and domain checks, an SMTP test, greylisting re-tests, typo correction, catch-all and disposable tests, plus free-provider and role-address detection.
• Catch-all handling, as a vendor claim. Official pages describe catch-all tests and a dedicated catch-all verifier, and say risky, unknown and catch-all results are not charged. Treat the “only verifier that does not charge for catch-all” line as a claim, and compare it with other tools on your own lists.
• Credit packs that official copy says do not expire. You buy a volume of credits once. Official Terms distinguish paid credits, which “do not expire merely because time passes,” from promotional credits, which also do not expire unless an expiry date was clearly disclosed when they were granted.
• ESP import and EverClean. An official integrations page names Mailchimp, Sendinblue, Mailgun, Mailjet, Elastic Email, Campaign Monitor, ActiveCampaign, Zoho CRM, Reply, GetResponse, HubSpot, AWeber, MailerLite and Drip. The homepage also lists SendGrid, Intercom and a custom app, and claims “40+” integrations. EverClean is described as a weekly automatic verification of connected ESP lists, with the option to remove bad addresses.
• A written money-back guarantee, with conditions. Marketing pages promise a 100% refund if, after verification, you see a hard-bounce rate above 4%. Official Terms require, among other things, a file upload (not only an API or one-by-one check), sending to every qualifying “OK” address within seven days, a count of hard bounces only, a professional sender that separates hard and soft bounces, and supporting reports. The refund, if those conditions are met, is of the most recent qualifying payment for paid credits. Promotional credits have a cash value of zero.

Key Features

• 100 free credits on a new account, officially with no credit card required.
• A public pay-as-you-go ladder from 10,000 credits at $39 up to 50 million credits at $8,499, with volume pricing above that on request.
• Official promotions: Million Evergreen (1 million extra credits for every 5 million purchased, including past payments) and Auto Top-Up (10% extra credits on payments when auto top-up is enabled). Treat availability and eligibility as stated at checkout.
• Results grouped as good, risky and bad on official product shots, with a “risky email refund” item on the pricing card.
• Help centre at help.millionverifier.com and API docs at developer.millionverifier.com, linked from the official site.

FAQs

How much does MillionVerifier cost?

A free account includes 100 credits. Paid packs start at $39 for 10,000 credits and go up to $8,499 for 50 million, with volume pricing above that. There is no public monthly subscription rate card on the pages we checked.

Do unused credits expire?

Official Terms say paid credits do not expire merely because time passes. Promotional credits also do not expire just with time, unless an expiry date was clearly disclosed when they were granted.

Is the 99% accuracy figure guaranteed?

No. The 99%+ figure is a vendor claim. The money-back guarantee in the Terms is about a hard-bounce rate above 4% on qualifying “OK” addresses, and only if the listed conditions are met.

Who provides the service?

Official Terms and the privacy notice, published 19 October 2026, name Southern Vector Limited, a New Zealand company, as the service provider. They say it acquired the MillionVerifier business from GBD Software as a Service Private Limited Company, a Hungarian company, and that valid unused credits transferred with the business.
