Email Verifier —
Surgical accuracy.
FixaConfirm's 10-step engine catches disposable addresses, spam traps, and dead MX records before you send a single email. Pay-as-you-go. No monthly subscription. Credits never expire.
Why email verification matters
Every time you send to an invalid address, your Email Service Provider (ESP) receives a bounce signal. Once your hard bounce rate exceeds 2%, Gmail, Outlook, and Yahoo begin routing your campaigns straight to spam.
Exceed 5% and your sending domain may be suspended entirely. Email verification is not optional for growth teams — it's table stakes for deliverability.
The 10-step verification engine
Most verifiers stop at DNS. We go further. Each email passes through 10 independent checks before we return a verdict — so you only send to inboxes that actually exist.
Syntax Check
Validates RFC 5322 email format — catches typos and malformed addresses instantly.
Domain Existence
Confirms the email domain is registered and active through DNS resolution.
MX Record Lookup
Checks that the domain has valid Mail Exchange records capable of receiving email.
SMTP Handshake
Pings the recipient mail server directly to confirm the mailbox exists — without sending an email.
Disposable Detection
Flags addresses from 10,000+ known temporary email providers like Mailinator.
Spam Trap Detection
Identifies recycled spam trap addresses that would immediately damage your sender reputation.
Catch-All Resolution
Detects domains that accept all emails, preventing false 'valid' results.
Role-Based Detection
Flags shared inboxes like admin@, support@, or info@ that hurt engagement rates.
Free Provider Check
Identifies consumer free email providers for B2B lead scoring workflows.
Confidence Scoring
Returns a 0–100 deliverability confidence score so you can set your own risk threshold.
Built for every use case
Bulk list cleaning
Upload a CSV of up to 500,000 addresses and receive a cleaned, scored list within minutes. Perfect before a major campaign launch.
Real-time API integration
Integrate our REST API into signup forms, CRMs, or lead magnets. Block bad addresses at the point of entry with sub-100ms response times.
CRM hygiene
Run quarterly bulk verifications on your HubSpot, Salesforce, or Pipedrive exports to remove contacts that have gone dark.
Spam trap removal
Sending to a spam trap destroys your domain reputation permanently. We flag known recycled spam traps before any email leaves your server.
Lead generation validation
Ensure every lead from your inbound funnel, webinars, or ad campaigns is verified immediately — not after your first send.
