Getting the Most from AI Enrichment
Prospi's enrichment engine finds and verifies email addresses for your leads using our internal email finder, built-in verification, and catchall detection. This guide explains how enrichment works, what data it adds, and tips for getting the best results.
How Enrichment Works
When you upload a list and run enrichment, Prospi looks up verified email addresses for each lead. Here is how to get the best results:
Provide complete input data - The email finder needs at minimum a first name, last name, and company domain. The more complete your data, the higher the match rate.
Format domains correctly - Use
acme.com, notwww.acme.comor justacme.Allow processing time for large lists - For lists of 5,000+ leads, enrichment runs in batches and may take 30–60 minutes. This is by design to ensure accuracy.
Re-run on remaining leads - After correcting any incomplete data, re-run enrichment on leads that were not matched in the first pass.
Understanding Enrichment Results
Verified Leads
These are email addresses that have been confirmed as active and deliverable. Verified leads are your highest-confidence contacts and are ready for campaigns.
Catchall Leads
A catchall domain is an email server configured to accept all emails sent to any address at that domain. The email address Prospi returns is still based on known patterns and is likely correct. Here is how to handle them:
Catchall results are common among legitimate businesses and are often perfectly valid contacts.
To be conservative, you can filter your campaign to separate catchall leads from verified leads and send to them at lower daily volume.
Monitor bounce rates on catchall leads. If bounces stay under 3%, you can continue sending to them confidently.
Verification Statuses Explained
After enrichment finds email addresses, Prospi's verification system validates them. Here are the possible statuses:
Verified - Confirmed active and deliverable. Ready for campaigns.
Catchall - Domain accepts all addresses. Likely valid but cannot be individually confirmed.
Unknown - The verification could not be completed on this pass. Wait 1–2 hours and re-run verification on these leads.
Invalid / Disposable - These should be removed from your campaign to protect your sender reputation.
Risky - Treat similarly to catchall - send with caution and monitor bounces.
Tips for Best Results
Always include company domain - This is the single most important field for successful enrichment.
Clean your data before enrichment - Remove duplicates, correct obvious typos in names, and validate domains.
Process in batches - For lists over 10,000 leads, split into smaller batches for faster, more reliable processing.
Check results before sending - Always review the enrichment summary (verified vs. catchall vs. not found) before launching a campaign.
Re-run when needed - If some leads show as "unknown," wait an hour or two and re-run verification. Most will complete successfully on the second pass.
