Key Advantages

Why Teams Switch from BriteVerify

Modern backend architectures require speed, strict data privacy, and up-to-the-minute domain intelligence.

Slash Verification Costs by 85%+

BriteVerify charges a flat $0.01 per verification ($100 for 10K, $1,000 for 100K checks). MailCheck delivers 10K checks for $15/mo and 100K checks for $124 ($49 Ultra plan + overage), saving engineering teams thousands in annual SaaS spend.

Sub-50ms Global Edge Performance

BriteVerify routes verification traffic through centralized US servers, adding 350ms-650ms to onboarding funnels. MailCheck executes in sub-50ms at distributed Cloudflare edge nodes globally.

40M+ Zero-Day Disposable Domain Intelligence

While legacy verification tools rely on periodic static feeds, MailCheck operates 24/7 background threat crawlers that identify and block disposable burner domains within minutes of registration.

Zero-Retention In-Memory Privacy (GDPR & SOC 2)

Never risk customer PII leaks. MailCheck processes all validation payloads purely in ephemeral RAM and discards them immediately, eliminating database exposure risks.

Code Migration

Drop-In Migration in Less Than 5 Minutes

Migrate your existing codebase effortlessly. Simply replace your endpoint URL with MailCheck on RapidAPI.

Before: BriteVerify

Legacy

const axios = require('axios');
const res = await axios.get('https://bpi.briteverify.com/emails.json', {
  params: { apikey: 'BRITEVERIFY_KEY', address: 'user@example.com' }
});

After: MailCheck API

// Modern MailCheck API call (~28ms, $0.001/chk)
const axios = require('axios');
const res = await axios.post('https://fadsync-email-validation.p.rapidapi.com/v1/check',
  { email: 'user@example.com' },
  { headers: { 'X-RapidAPI-Key': 'YOUR_KEY', 'X-RapidAPI-Host': 'fadsync-email-validation.p.rapidapi.com' } }
);

Frequently Asked Questions

Common questions about migrating from BriteVerify to MailCheck API.

BriteVerify by Validity was built for legacy CRM bulk scrubbing with slow origin response times (~450ms) and rigid $0.01/check pricing. MailCheck API is designed specifically for real-time developer auth pipelines, offering sub-50ms edge latency, 40M+ disposable domain protection, zero-retention privacy, and up to 87% lower cost.

BriteVerify charges $1,000 for 100,000 checks ($0.01 per verification). With MailCheck, 100,000 monthly checks cost $124 ($49 Ultra plan + 50k overage at $0.0015/check), saving $876 every month (an 87.6% reduction in verification costs).

MailCheck adheres to a strict Zero-Retention Protocol. Email verification payloads are processed purely in ephemeral RAM at the edge node and immediately purged. We never store or log user emails, making compliance audits effortless.

Migration typically takes under 5 minutes. Both APIs accept an email string and return validation verdicts. Simply update your API endpoint URL and headers to point to the MailCheck RapidAPI gateway.
