Most teams don't find out until open rates collapse and deliverability plummets.
On average, 25% of email addresses go bad each year. You're wasting budget on contacts who can never receive your emails.
A single bad campaign can tank your deliverability for months. ISPs blacklist senders with bounce rates above 2%.
Catch-all domains and honeypot addresses lurk in purchased or scraped lists. One hit can trigger a full blacklisting.
6 powerful verification layers. One API. Complete confidence before every send.
Sub-500ms real-time verification via REST API. Perfect for form validation, CRM triggers, and event registration flows.
Process up to 10M emails overnight. Upload CSV or XLSX, or connect via API. Parallel Go workers for maximum throughput.
A+ to F grades — not just valid/invalid. Understand deliverability confidence and segment your sends by grade.
Detect spam traps, disposable domains, role accounts, and catch-all addresses across our 10-stage pipeline.
SPF, DKIM, and DMARC checks included in every result — not a separate paid feature.
Never email a bad address twice. Upload custom suppression files or sync from your ESP automatically.
No complex setup. No engineering required. Just clean email data.
Drop a CSV, paste emails, or send via API. Supports up to 10M records per batch.
Choose Tier 1 (syntax + DNS + SMTP) or Tier 2 (full risk scoring + catch-all ML).

“DMPHub cut our bounce rate from 8.4% to 0.3% in the first batch. Our deliverability scores have never been higher. The quality grading system is a game-changer — we now segment sends by grade.”
Sarah Chen
Head of Growth · Meridian SaaS
“We process 2 million contacts per month and DMPHub handles it without breaking a sweat. The API response times are consistently under 400ms and the catch-all ML is genuinely impressive.”
Marcus Weber
VP Engineering · Euronova Group
“As a marketing agency we manage 40+ client lists. The suppression list feature alone saves us hours every campaign. Domain health checks surfacing DMARC issues caught several brand-damaging problems early.”
