VeriMails vs MillionVerifier

Verification Accuracy

MillionVerifier's accuracy for standard mailboxes is reasonable. They use the typical verification chain: syntax, DNS, MX, and SMTP checks. For straightforward valid/invalid addresses, results are comparable to other providers. The issue is twofold: catch-all domains receive only a binary flag (no scoring), and the slow processing speed means results aren't available for hours. For time-sensitive workflows, this is a serious limitation. VeriMails runs real-time SMTP verification with results in under 2 seconds per address. Combined with catch-all probability scoring, you get faster, richer results.

Catch-all Domain Handling

MillionVerifier's approach to catch-all domains is the industry default: mark them as catch-all and move on. For users verifying massive purchased lists, this means a significant portion of addresses remain in limbo. VeriMails' pattern scoring transforms this unknown pool into actionable segments. Score above 80? Safe to send. Below 30? Skip it. Between 30-80? Send with caution or hold for re-verification. This granular approach is especially valuable for B2B lists where catch-all corporate domains are common.

API and Developer Experience

MillionVerifier offers a REST API, but the service was clearly designed with bulk CSV upload as the primary workflow. API response times are significantly slower than competitors — verification can take several seconds or more per address, and bulk jobs through the API can queue for extended periods. VeriMails was built API-first. Every feature is accessible through our REST API with sub-second response times. The same endpoint that powers our dashboard is available to you. Real-time verification for signup forms, batch processing for list cleaning, and webhook callbacks for async workflows.

Pricing and Value

MillionVerifier's headline price is compelling: approximately $0.0015 per email for bulk verification, with packages starting at $59 for 50,000 verifications. At 100,000 emails, the cost is roughly $89-$118. VeriMails uses a simple credit-based model with no subscriptions or monthly fees. Buy credits as needed, starting at $19 for 10,000 verifications ($0.0019/email). Credits never expire. At 100,000 verifications, VeriMails costs $99 — significantly less than most competitors. All plans include catch-all scoring, the API, and bulk verification at no extra cost. 100 free credits on signup, no credit card required.

Cost Comparison at Scale

Who VeriMails Is Best For

Teams that need real-time verification (signup forms, API integrations). Anyone who needs catch-all probability scoring. Users who verify 10K-50K emails monthly (similar cost, vastly better features). Developers building verification into their workflows.

Who MillionVerifier Is Best For

Budget-constrained teams verifying massive lists (500K+) where per-email cost is the only priority. Batch-only workflows where speed doesn't matter. Users who don't need catch-all scoring or real-time API access.
