Verify 130k Email Addresses

I’m sitting on a raw list of roughly 130,000 email addresses that currently triggers both soft and hard bounces. My sole objective is to raise overall deliverability, so every single address must be checked for full deliverability issues—syntax, domain validity, mailbox existence, role/disposable addresses, possible spam traps—rather than simply stripping obvious hard bounces.

Here’s what I need from you:

• Run a comprehensive verification sweep using a trusted solution such as NeverBounce, ZeroBounce, MillionVerifier, or an equivalent SMTP-ping setup that never sends an actual message.
• Return two clearly labeled CSVs: one “Valid & Safe” file ready for import, and one “Invalid / Risky” file that lists each rejected address with the specific reason it failed.
• Include a brief summary report showing the percentage removed and the projected bounce rate; I’ll test a sample to confirm we’re below 2%.
• Preserve any existing IDs or column order so I can merge results back into my CRM without headaches.

Turnaround of 48–72 hours is ideal, but let me know what you can realistically commit to and your past experience handling lists of this size. Once delivered and spot-checked, I’ll release payment promptly and look forward to working together again on future sends.
