Scrubby specializes in catch-all email verification, making it the most directly competitive alternative to VeriMails' catch-all scoring. Scrubby uses a multi-pass approach over several days to determine catch-all deliverability, while VeriMails provides instant probability scores. Choose based on whether you prefer accuracy-over-time or speed-with-scoring.

| Bulk verification | Fast CSV processing | CSV upload |
| Speed | Sub-2 second | Slow (multi-pass) |
Scrubby takes a unique approach: they send test emails to catch-all domains over multiple days and monitor for bounces. This multi-pass method provides high confidence for the specific addresses tested, but requires patience — results can take 3-7 days. For standard (non-catch-all) verification, Scrubby's capabilities are more limited than traditional verifiers. VeriMails provides real-time catch-all probability scoring — results in seconds, not days. Our pattern analysis approach is different from Scrubby's test-send method, but provides immediate actionable scores. For standard verification, VeriMails offers full SMTP verification that Scrubby doesn't focus on.
This is the core comparison point. Scrubby's approach: send test emails, wait for bounces over multiple days, confirm deliverability by absence of bounces. This is thorough but slow, and only works for the specific addresses tested. VeriMails' approach: analyze naming patterns, domain configurations, and historical data to generate probability scores in real-time. This is instant but probability-based rather than confirmation-based. Both solve the catch-all problem — Scrubby with patience and direct testing, VeriMails with speed and pattern analysis.
Scrubby's API is geared toward their specific workflow: submit catch-all addresses, wait for results over days, retrieve final verdicts. This async-heavy model is fine for batch processing but doesn't support real-time verification. VeriMails' API supports both real-time single verification (sub-2-second responses) and batch processing. Catch-all probability scores are included in every response instantly.
Scrubby charges approximately $0.004 per email for their catch-all verification service. Pricing varies by volume. At 10,000 emails, expect roughly $40. At 100,000, approximately $400. VeriMails at $0.0029/email costs $29 for 10,000 and roughly $290 for 100,000 — plus you get full standard verification, not just catch-all handling. VeriMails is both cheaper and more comprehensive.
| Volume | VeriMails | Scrubby |
|---|---|---|
| 10,000 emails | $29 | ~$40 |
| 100,000 emails | ~$290 | ~$400 |
Teams needing instant catch-all scores (not willing to wait days). Users who need full email verification, not just catch-all handling. Developers building real-time verification into workflows. Cost-conscious teams wanting comprehensive verification.
Teams willing to wait days for the highest possible catch-all accuracy. Organizations focused exclusively on catch-all domain verification. Users who prefer confirmation-based results over probability-based scoring. Companies verifying large static lists that don't change frequently.
Scrubby's test-send approach can provide higher confidence for specific addresses because it uses actual delivery testing. However, it takes days instead of seconds. VeriMails' probability scoring is instant and covers the vast majority of cases accurately. For most workflows, the speed advantage outweighs the marginal accuracy difference.
Scrubby specializes in catch-all verification and isn't designed as a full email verification service. For standard verification (syntax, MX, SMTP, disposable detection), you'd still need a service like VeriMails alongside Scrubby.
Scrubby's multi-pass approach typically takes 3-7 days for results. VeriMails provides catch-all probability scores in under 2 seconds per address. For time-sensitive workflows, VeriMails is the practical choice.
For maximum catch-all accuracy, you could use VeriMails for immediate scoring and Scrubby for high-stakes lists where you can wait. However, for most use cases, VeriMails' probability scoring alone provides sufficient accuracy.
