Step 01
Upload your list
Upload a CSV or Excel file from your CRM, outbound tool, or spreadsheet. We auto-detect the email column — no reformatting needed. Up to 10,000 rows per upload.
Supports CSV and XLSX

Clean your email lists before you send
How it works
A clear workflow from upload to clean export
BounceProtect is designed for busy sales and marketing teams. Upload once, review quality signals fast, and export data you can confidently use.
Step 02
We run 10 signals per email
Every address is checked for syntax errors, MX records, disposable domains (121K+ known), role accounts, domain typos, catch-all servers, SPF/DMARC authentication, free provider detection, spam risk score, and a plain-English send recommendation.
Real-time, parallel validation
Step 03
Review with full context
Every email gets a status (valid, risky, invalid, unknown), a deliverability score from 0–100, a spam risk score, and a send recommendation (Send / Caution / Review / Don't send). Not just a label — a reason and a decision.
Deliverability score + send recommendation
Step 04
Run Deep Analysis on your domains
After validation, run Deep Analysis to check every unique domain for business legitimacy — website presence, SSL, domain age, mail provider, safe browsing status, and company intelligence from our 22M+ organisation database.
22M+ company records matched
Step 05
Export or integrate
Download an enriched CSV with all signals as new columns, ready to import into your CRM or sending tool. Use the REST API for programmatic validation, or connect to 5,000+ apps via our native Zapier integration — validate form submissions, enrich CRM contacts, and trigger actions automatically.
