Pipeline

8-step validation pipeline

Every email runs through 8 checks in parallel. Bad emails caught at the edge before they reach your database.

01
Syntax Check
RFC 5322 compliance. Max 254 chars. TLD verification against IANA registry.
02
DNS + MX Lookup
Domain exists? Can it receive mail? Dual-provider failover for reliability.
03
Disposable Detection
5,300+ temp email providers flagged. Updated regularly from active threat feeds.
04
Typo Correction
gmial.com → gmail.com. Levenshtein distance matching across 60+ major domains.
05
Role-Based Detection
Flags info@, admin@, support@ and 22 other role-based prefixes.
06
Free Provider ID
Detects Gmail, Outlook, Yahoo, ProtonMail and 40+ other free providers.
07
Catch-All Detection
Identifies wildcard domains that accept everything — unreliable for delivery.
08
SMTP Verification
Mailbox-level check. Confirms inbox actually exists. Available on Pro+ tiers.

FAQ

Common questions

How is RiskMail so much cheaper?
Edge-native architecture on Cloudflare Workers — no legacy servers, no idle compute, no bloated infrastructure. Costs scale linearly with usage and we pass the savings directly to you.
What's included in the free tier?
50 requests per month with all 8 validation steps: syntax, DNS, MX, disposable detection, typo correction, role-based checks, catch-all detection, and risk scoring. SMTP mailbox verification and bulk endpoints require a paid plan.
Does RiskMail support SMTP verification?
Yes. Pro ($14.99/mo) and above include SMTP mailbox verification — we communicate directly with the mail server to confirm the inbox exists. Essential for high-value validation workflows.
Can I validate emails in bulk?
Ultra ($34.99/mo) supports 50 emails per request. Mega ($89.99/mo) supports 100 per request with 300 req/min rate limiting — enough for cleaning large lists efficiently.
How accurate is the validation?
Our 8-step pipeline runs every check in parallel — syntax, DNS, MX records, disposable provider matching against 5,300+ providers, typo detection across 60+ domains, role-based prefix identification, catch-all domain detection, and SMTP verification. Each check contributes to a composite risk score from 0-100.
