filtrat.io is B2B email verification that resolves catch-all domains to confirmed deliverable or bounce.
Every email verifier on the market detects catch-all domains and stops. The address comes back as "risky" or "unknown" and you decide: skip it or send blind. That is 20-30% of every B2B list - real people at real companies that your verifier gave up on.
filtrat.io checks whether the actual mailbox exists. From 1,000 catch-all addresses we return 600-700 confirmed results. What we can't resolve - you don't pay.
How it works: upload a list, get results split by status. Confirmed deliverable and confirmed bounce cost 0.5 credits each. Catch-all addresses are flagged for free. Resolve them individually at 3 credits per confirmed result. Uncertain, risky, and unresolved addresses cost nothing.
Additional features: email pattern lookup shows the naming format for any domain (first.last@, firstname@) before you spend credits on resolution. Domain health checks show MX provider, catch-all status, and authentication records for free. Typo detection catches misspelled domains before verification. Results are cached for 180 days - re-uploads cost nothing for previously checked addresses.
Integrations: REST API with full documentation, pre-built n8n workflow templates for single verification, bulk list cleaning, webhook validation, and catch-all resolution. MCP server coming soon.
Pricing starts at $10/mo for 24,000 verified results. Pay-as-you-go packs available with credits that never expire. 200 free credits to test without a card.
Built for lead gen agencies, sales teams, and anyone who sends cold email and needs every deliverable contact recovered from their lists.

filtrat.io's answer
Every email verifier detects catch-all domains and stops. filtrat.io resolves each address individually to confirmed deliverable or bounce.
That is 20-30% of every B2B list that other tools mark "unknown" and walk away from. We return 600-700 confirmed results per 1,000 catch-all addresses.
What we can't resolve costs nothing.
filtrat.io's answer
Lead generation agencies running cold email campaigns, B2B sales teams doing outbound outreach, and SaaS companies cleaning prospect lists before sending. Anyone who works with B2B email lists and loses 20-30% of contacts to catch-all domains.
filtrat.io's answer
I was building lead gen pipelines for clients and every pipeline had the same leak - catch-all emails that no verifier could resolve. I tried MillionVerifier, NeverBounce, ZeroBounce, Bouncer. All of them flagged catch-all as "risky" and stopped. The workaround was Scrubby which sends real emails from Gmail accounts and takes 24-72 hours. I built filtrat.io to resolve catch-all in seconds without sending anything to the prospect's inbox.
filtrat.io's answer
Three reasons. First - catch-all resolution is built in, not a separate tool or third party. MillionVerifier recommends Scrubby, NeverBounce charges but doesn't resolve, ZeroBounce charges double for an AI score. filtrat.io confirms. Second - you only pay for confirmed results. Uncertain, risky, and unresolved addresses are free. Third - pricing. A 10,000 email list costs $10 on filtrat.io with catch-all resolution included. The same list costs $39-111 on competitors without resolution.
