How much cheaper is NoBounce compared to ZeroBounce, NeverBounce, and Kickbox?

At 100,000 email validations per month, NoBounce costs $99/month ($79/month billed annually, or $0.00079 per email), compared to ~$390 at ZeroBounce, ~$400 at NeverBounce, and ~$800 at Kickbox — a 75% to 90% cost reduction.

How fast is the NoBounce Email Validation API?

Standard validation (RFC 5322 syntax, live DNS/MX record verification, 150+ disposable provider detection, role-account detection, and domain typo suggestions) completes in ~15ms. Optional deep SMTP mailbox handshakes can be enabled per request with smtp_check=true.

Can I use NoBounce in n8n, Clay, Make, or AI Agents (MCP)?

Yes. Install the official n8n community node (n8n-nodes-nobounce), connect via our official MCP server (npx -y nobounce-mcp or https://nobounceapi.com/mcp), or call GET/POST https://nobounceapi.com/api/validate from Clay.com, Make.com, or Zapier.

Drop-In REST API Replacement

Switching from ZeroBounce, NeverBounce, or Kickbox takes less than 5 lines of code. And unlike legacy batch APIs that force you to poll async jobs, POST /api/validate-bulk validates up to 5,000 emails in a single call:

Single Email Validation (cURL / Python / Node)

curl -s "https://nobounceapi.com/api/validate?email=support@google.com" \
  -H "X-API-Key: nb-your-api-key"

Synchronous Bulk Batch Validation (Up to 5,000 Emails)

curl -s -X POST "https://nobounceapi.com/api/validate-bulk" \
  -H "X-API-Key: nb-your-api-key" \
  -H "Content-Type: application/json" \
  -d '{"emails": ["support@google.com", "user@mailinator.com"]}'
