MillionVerifier

What is MillionVerifier?

MillionVerifier is a cost-effective email verification platform designed for sales teams, marketers, agencies, and lead generation operations that need to clean email lists at scale without breaking the budget. Founded with a focus on making email validation accessible to small and mid-market teams, MillionVerifier delivers 99%+ verification accuracy at prices that undercut most competitors by 40–60%.

The platform specializes in identifying invalid addresses, spam traps, disposable emails, and syntax errors before you hit send—protecting your sender reputation and improving deliverability rates. Whether you’re validating a 5,000-contact lead magnet list or scrubbing 5 million scraped records, MillionVerifier processes files quickly through both bulk upload and real-time API verification.

While premium competitors offer tighter catch-all detection and faster support, MillionVerifier excels at delivering reliable, affordable email validation for teams where cost per verification directly impacts ROI.

How MillionVerifier Works

MillionVerifier uses a multi-layered validation process that checks every email address against multiple data points:

1. Syntax & Format Validation: Identifies typos, missing @ symbols, and malformed addresses that will hard bounce.

2. Domain Verification: Confirms the domain exists, has valid MX records, and is actively receiving mail.

3. Mailbox Verification: Connects to the recipient’s mail server (without sending an email) to verify the specific mailbox exists.

4. Risk Detection: Flags disposable emails (temp-mail services), role accounts (info@, sales@), spam traps, and known complainers.

5. Result Classification: Returns one of six statuses—Ok (deliverable), Catch-All (server accepts all), Invalid (bounces), Disposable, Unknown, or Duplicate.

The entire process happens in seconds for real-time API calls or minutes to hours for bulk list processing, depending on file size.

Key Features

Real-Time Email Verification API

MillionVerifier’s REST API lets you validate email addresses instantly as users sign up on landing pages, webinar forms, or lead capture tools. Integrating the API takes minutes with libraries for JavaScript, Python, PHP, and cURL examples in the documentation. Real-time verification prevents bad emails from entering your CRM in the first place, saving cleanup costs later.

Bulk List Cleaning

Upload CSV or TXT files containing up to millions of email addresses. MillionVerifier processes the list and returns a cleaned file with validation status for each contact. The platform handles:

• Removal of duplicate entries
• Typo correction suggestions (e.g., “gmial.com” → “gmail.com”)
• Identification of spam traps and honeypots
• Separation of valid, invalid, and risky contacts

Processing speeds average 200,000–500,000 emails per hour, making it practical for large-scale list hygiene.

Native ESP & CRM Integrations

MillionVerifier is the only verification service offering one-click integrations with 17 major email marketing platforms, including:

• Mailchimp, Sendinblue, ActiveCampaign, AWeber, GetResponse
• Mailgun, Mailjet, Elastic Email, Campaign Monitor
• BombBomb, EmailOctopus, SendPulse, Drip

CRM integrations include HubSpot, Pipedrive, Zoho, Agile CRM, Insightly, and Salesflare. For platforms without native support, connect via Zapier to access 8,000+ additional apps.

EverClean Automated Monitoring

EverClean continuously monitors your email list for changes—mailboxes that go inactive, domains that expire, or addresses that become spam traps. Pricing starts at $0/month for up to 1,000 emails and scales to $649/month for 1 million monitored contacts. This keeps your list fresh without manual re-verification every quarter.

Credit-Based Pricing Model

MillionVerifier uses pay-as-you-go credits that never expire. You’re not locked into monthly subscriptions or forced to burn unused verifications. This model works especially well for:

• Seasonal campaigns where list sizes fluctuate
• Agencies managing multiple client lists
• Teams with unpredictable lead generation volume

Pricing

MillionVerifier offers one-time credit packages with volume-based discounts. The more you buy, the lower the per-verification cost:

EverClean Subscription Plans

For automated list monitoring:

• Free: Up to 1,000 emails
• $15/month: 10,000 emails
• $37/month: 50,000 emails
• $149/month: 250,000 emails
• $649/month: 1,000,000 emails

Free Trial

MillionVerifier offers a no-credit-card free trial to test verification quality before committing. Trial includes access to the full feature set with a limited credit allocation.

Ideal Use Cases

MillionVerifier is purpose-built for teams and operators who need cost-effective email validation at scale:

• Lead generation agencies cleaning scraped or purchased lists before handing them to clients
• B2B sales teams validating prospect lists from data vendors (ZoomInfo, Apollo, Lusha)
• Email marketers reducing bounce rates to protect sender reputation
• SaaS companies preventing fake signups and disposable email abuse
• Event organizers verifying webinar registrations and attendee lists
• E-commerce brands cleaning newsletter subscriber lists before Black Friday campaigns

If your primary concern is cost per verification and you’re willing to accept slightly lower catch-all accuracy, MillionVerifier delivers exceptional value. Teams requiring the absolute highest precision on edge cases (especially catch-all domains) may prefer premium alternatives like ZeroBounce or Bouncer despite higher costs.

MillionVerifier vs. Competitors

Bottom Line: MillionVerifier is the budget leader in email verification, making it ideal for high-volume operations where cost matters more than perfect catch-all handling. For mission-critical lists (e.g., investor pitches, high-ticket sales), consider spending more on ZeroBounce or Bouncer.

Pros and Cons

Pros

✅ Lowest pricing in the industry—up to 70% cheaper than ZeroBounce ✅ Fast bulk processing handles millions of emails quickly ✅ 17 native ESP integrations plus Zapier connectivity for 8,000+ apps ✅ No monthly fees or expiring credits—pay only when you need verifications ✅ Free trial with no credit card lets you test before buying ✅ 96% of users praise value for money according to reviews ✅ Real-time API prevents bad emails from entering your database

Cons

Implementation Notes

Getting Started

1. Sign up at millionverifier.com and claim your free trial credits.
2. Upload a test list (CSV or TXT) to validate verification quality against your specific list type.
3. Review results and compare accuracy against a sample you’ve manually verified.
4. Purchase credits based on your list size and cleaning frequency.
5. Integrate via API for real-time verification or connect your ESP/CRM for automated cleaning.

API Integration

MillionVerifier’s API is RESTful and returns JSON responses. A typical verification call looks like:

GET https://api.millionverifier.com/api/v3/?api=[YOUR_KEY]&email=[EMAIL_ADDRESS]

Response includes status (ok, invalid, catch_all, disposable, unknown), along with metadata like free/role account detection and typo suggestions.

Documentation at developer.millionverifier.com includes code examples for all major languages.

Best Practices for List Cleaning

• Pre-verification: Remove obvious syntax errors and duplicates locally before uploading to save credits.
• Catch-all handling: Flag catch-all addresses for manual review or secondary verification rather than auto-removing them.
• Re-verification cadence: Clean lists every 90 days if contacts are older than 6 months, or before major campaigns.
• ESP monitoring: Use EverClean for lists that change frequently (webinar signups, ongoing lead magnets).

Deliverability Considerations

Email verification alone won’t guarantee inbox placement—it prevents hard bounces, which damage sender reputation. To maximize deliverability:

• Combine MillionVerifier with email warmup tools (MailReach, Mailwarm) to build domain reputation.
• Set up SPF, DKIM, and DMARC authentication before sending cold campaigns.
• Monitor bounce rates post-campaign; if they exceed 2%, re-clean your list with stricter filtering.
• Avoid sending to catch-all domains unless you have existing engagement history.

Final Verdict

MillionVerifier earns its spot as the go-to budget email verification platform for teams that need reliable validation without enterprise pricing. While catch-all detection and Yahoo email handling lag behind premium competitors, the platform delivers excellent value for most use cases—especially high-volume list cleaning where cost per verification directly impacts margins.

For agencies juggling dozens of client lists, sales teams buying data from vendors, or marketers running seasonal campaigns, MillionVerifier’s pay-as-you-go model, native ESP integrations, and rock-bottom pricing make it a no-brainer. Just be prepared to manually review catch-all results and supplement with warmup tools for optimal deliverability.

Best for: Cost-conscious teams cleaning large email lists, agencies managing multiple clients, and marketers validating lead magnets or purchased data.

Skip if: You need perfect catch-all accuracy for high-stakes outreach, require white-glove customer support, or are validating mission-critical lists where false positives are unacceptable.
