Bounce Protect

Clean your email lists before you send

How it works

A clear workflow from upload to clean export

Bounce Protect is designed for busy sales and marketing teams. Upload once, review quality signals fast, and export data you can confidently use.

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

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. Or use the REST API to validate programmatically from any workflow — single email or bulk up to 100 at a time.
