RevOps workflow

Clean data before it reaches your sending infrastructure.

Import or connect your list

Upload a CSV, connect via API, or verify contacts as they are found. OutPulse accepts addresses from any source — purchased lists, CRM exports, or inbound forms.

Run multi-layer verification

Syntax, DNS, MX, SMTP, catch-all, and disposable checks run in sequence. Each address gets a clear classification and confidence score.

Export only deliverable contacts

Push verified records to HubSpot, Salesforce, your ESP, or a cleaned CSV. Risky and invalid addresses stay out of your sending pool.

Deliverability primitives

The verification layer your sending stack is missing.

Real-time SMTP validation

Every check pings live mail servers — not stale databases that decay 30% per year. Sub-500ms responses on single and batch requests.

Valid, Invalid, Catch-all, and Disposable classifications
98.7% accuracy across B2B domains
