Sorry you’re running into that. If Hunter Email Verifier is disappointing on bulk uploads, the issue is often one of these: accuracy, speed, credits, or file-handling limits.
A few practical ways to improve the experience:
- Upload smaller batches: bulk verification often performs better in chunks instead of one huge file.
- Clean the list first: remove duplicates, role-based emails, obviously invalid formats, and old contacts.
- Check the status labels carefully: “valid,” “invalid,” “catch-all,” and “unknown” are not equally reliable for bulk decisions.
- Use a second verifier for risky segments: especially if you’re seeing a lot of catch-all or unknown results.
- Verify only your highest-value contacts: if credits are limited, prioritize by recency or importance.
- Review input formatting: bad CSV headers, extra columns, or encoding issues can cause upload problems.
If you want, I can help you with either of these:
- Troubleshoot Hunter bulk upload issues, or
- Suggest better bulk email verification tools depending on what you care about most, like accuracy, speed, or cost.
