Bulk Email Verification Needed
Budget: $250 – $750 USD
I’m ready to clean up my contact database and need an experienced hand to do it accurately and fast. You’ll receive a raw list of addresses; your job is to confirm which ones are truly deliverable and flag every bad, risky, or unknown entry before my next campaign goes out.
What I expect from you
• Return the list in CSV/XLSX, preserving the original order, with each email clearly tagged as valid, invalid, catch-all, disposable, or syntax error.
• Provide a short error-breakdown report that shows counts and percentages, so I can see overall health at a glance.
• If you notice consistent DNS, SPF, or other configuration problems, add a brief recommendation section—nothing formal, just actionable notes I can pass on to my tech team.
I’m flexible on tooling: whether you rely on a commercial API (ZeroBounce, NeverBounce, etc.) or your own SMTP-ping script is up to you, as long as the results are reliable and delivered on schedule. Confidentiality is essential; the list can’t be resold or reused in any form.
Let me know:
1. The verification method or service you prefer.
2. Turnaround time for the size of list you’re comfortable handling.
3. Anything you need from me beyond the raw CSV.
Once we agree on those points, I’ll forward the file and you can start immediately.
