Migration guide

Switch to filtrat.io From Any Email Verifier

No lock-in, no data loss, no downtime. Test alongside your current tool, compare results, switch when the numbers convince you.

You Do Not Need to Switch All at Once

The worst way to change your verification tool is to cancel your current subscription and hope the new one works. The best way is to run both side by side until the results speak for themselves.

filtrat.io gives you 200 free credits to start. That is enough to verify 400 addresses and see how results compare with your current tool. No card required.

Three Migration Paths

1

Side-by-Side Test

Best for: teams who want proof before switching.

  1. 1Take your next campaign list (500-1,000 emails)
  2. 2Verify with your current tool
  3. 3Verify the same list with filtrat.io
  4. 4Compare: how many your tool marks catch-all/risky vs how many filtrat.io resolves to confirmed
  5. 5When results convince you, switch

Time: 30 minutes. Cost: free (200 credits).

2

Catch-All Layer First

Best for: teams happy with their current standard verifier.

  1. 1Keep your current tool for standard verification
  2. 2Export catch-all / accept-all / risky results
  3. 3Upload to filtrat.io for resolution
  4. 4600-700 out of 1,000 come back confirmed
  5. 5Merge resolved results with your clean list

Your current tool handles standard. filtrat.io handles catch-all. No disruption. Time: 10 minutes per list. Cost: Growth plan $25/mo — resolve catch-all from the same credit balance.

3

Full Replacement

Best for: teams tired of paying for two tools or overpaying for one.

  1. 1Sign up for a filtrat.io plan
  2. 2Generate an API key
  3. 3Update your pipeline (n8n, Clay, Zapier, or direct API)
  4. 4Swap the endpoint — same JSON in, same status out
  5. 5Cancel your previous tool after one successful campaign

filtrat.io's API returns the same core statuses: deliverable, invalid, catch-all, uncertain. Your downstream logic does not change.

What Changes, What Does Not

What stays the same

Same result types (valid, invalid, catch-all, unknown)
Same API pattern (POST with email, JSON response with status)
Same CSV upload/download workflow
Same campaign workflow downstream

What improves

What you lose (honestly)

ESP integrations (Mailchimp, HubSpot native sync) — filtrat.io is API-first, connect via n8n, Zapier, or Make
Data enrichment — use a separate tool
SOC 2 / ISO 27001 — not yet

API Migration — Swap One Endpoint

If your pipeline uses an API, migration is one endpoint change:

Old (NeverBounce example)

POST /v4/single/check
→ {"result": "catchall"}

New (filtrat.io)

POST https://api.filtrat.io/v1/verify/email
→ {"status": "catchall",
   "catchall_resolved": true}

Same pattern. Same logic. One line changed in your config.

n8n Migration — Import a Template

If you use n8n, swap the HTTP node or import a ready-made template:

  1. 1Remove old verifier HTTP node
  2. 2Import filtrat.io template
  3. 3Paste API key
  4. 4Done

Templates available for single verification, bulk list cleaning, webhook validation, and catch-all resolution.
