Multi-layer validation
Connect directly to the recipient mail server and confirm inbox existence — without sending a message or notifying the recipient.
Every address returns one status: Valid, Invalid, Catch-All, Role-Based, Disposable, or Spam Trap — with configurable thresholds.
Upload large lists and get a fully classified, export-ready file — or push verified records to your CRM in one step.
How it works
Verify a single address instantly, or drop a CSV of any size. OutPulse detects email fields automatically.
Syntax, DNS, MX records, SMTP handshake, disposable detection, catch-all identification, and role-based filtering — in one pass.
Download classified results as CSV, or send verified contacts to HubSpot, Salesforce, or your stack via API.
