Deliverability is a data problem disguised as a sending problem. OutPulse validates every address against live mail servers before it enters your ESP, sequence tool, or CRM — so marketing ops and RevOps catch bad records upstream.

RevOps workflow
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.
Syntax, DNS, MX, SMTP, catch-all, and disposable checks run in sequence. Each address gets a clear classification and confidence score.
Push verified records to HubSpot, Salesforce, your ESP, or a cleaned CSV. Risky and invalid addresses stay out of your sending pool.
Deliverability primitives
Every check pings live mail servers — not stale databases that decay 30% per year. Sub-500ms responses on single and batch requests.
Upload CSVs of any size for parallel verification, deduplication, and risk scoring. Export cleaned files formatted for your CRM or ESP.
Embed deliverability checks into any product, form, or pipeline. Webhooks fire on completion for event-driven architectures.
