Hello, I am an experienced email data specialist who has successfully cleaned and verified lists exceeding 200,000 contacts using ZeroBounce and NeverBounce, consistently achieving deliverability rates above 98%. For your 130,000-record list, I will run a comprehensive verification sweep checking syntax, domain validity, mailbox existence, role-based addresses, disposable domains, and potential spam traps—ensuring only truly safe addresses remain. You will receive two clearly labeled CSVs: a "Valid & Safe" file ready for import preserving your original column order and IDs, and an "Invalid / Risky" file with specific failure reasons for each rejected address. I will also provide a brief summary report showing removal percentage and projected bounce rate for your sample test. I can complete this within 48 hours and am ready to start immediately. Regards, Zafar

Hi there, I will verify your 130,000-address list end-to-end using SMTP-safe checks and an industry service (NeverBounce or MillionVerifier) so you get a clean, import-ready file and measurable lift in deliverability. My background in bulk list hygiene, SMTP validation, and CRM-preserving exports ensures I keep your IDs/column order intact and provide precise failure reasons. - Full verification sweep (syntax, domain DNS/MX, SMTP-ping mailbox checks, role/disposable/spam-trap detection) and deduplication; preserve original columns and IDs. - Deliver two CSVs: “Valid & Safe” (ready to import) and “Invalid / Risky” with per-address failure reason and error code. - Summary report: total checked, % removed, projected bounce rate, samples for your 2% verification. - Quality control: staged processing, validation samples, rollback/restore of original file, and secure handling of data (no messages sent). Skills: ✅ Data Management ✅ SMTP-ping / Email Verification (NeverBounce / MillionVerifier) ✅ Workflow: staged processing & sample validation ✅ Hosting/Export: CSV preservation & CRM-ready formatting ✅ Security & deliverability: spam-trap detection, bounce projection Certificates: ✅ Microsoft® Certified: MCSA | MCSE | MCT ✅ cPanel® & WHM Certified CWSA-2 I’m available to start immediately. What CSV format does your CRM expect (column headers to preserve)? Do you have any rate limits or API keys for NeverBounce/ZeroBounce already, or should I provision and cover third-party verificati

Hi, I can help you clean and verify your 130,000 email list to significantly improve deliverability and keep your bounce rate well below 2%. I have solid experience handling large email datasets and verifying them using trusted tools such as NeverBounce, ZeroBounce, and MillionVerifier, combined with advanced checks for: Syntax validation Domain & MX record verification SMTP mailbox verification (no email sent) Detection of role-based, disposable, and catch-all addresses Identification of possible spam traps and risky emails What you will receive: • Valid & Safe CSV – Clean list ready for import and sending • Invalid / Risky CSV – Each rejected email with the exact reason (hard bounce, role-based, disposable, spam trap risk, etc.) • Summary Report – Total processed, % removed, and projected bounce rate • Original column order and IDs preserved so you can easily merge results back into your CRM. For a list of 130K emails, I can realistically complete the full verification and quality check within 48–60 hours while ensuring accuracy. I’ve worked on several large-scale email verification and lead data projects, so I understand the importance of deliverability, data hygiene, and CRM compatibility. If you'd like, I can also verify a small sample first so you can see the quality before processing the full list. Looking forward to working with you.

As a seasoned data manager, I understand the significance of having a clean, reliable email list for effective communication. I have successfully handled numerous projects of this magnitude, providing comprehensive verification services, similar to what you desire. I am well-versed in using trusted tools such as NeverBounce and MillionVerifier, or if you prefer a non-message sending alternative, an equivalent SMTP-ping setup. My approach guarantees accuracy not only in detecting hard bounces but also in ensuring syntax, domain validity, mailbox existence, role/disposable addresses, and identifying possible spam traps. In my experience, it is not enough to simply categorize emails as valid or invalid; they must be accompanied by specific reasons why they failed. Rest assured, your "Valid & Safe" and "Invalid / Risky" files will not only identify each rejected address but also provide clarity on why they did not pass the verification check. Additionally, I will include a detailed summary report showing the percentage of emails removed and the projected bounce rate to help you confirm that we are below 2%, prior to importing them back into your CRM system.

Hello, Handling large email lists and improving deliverability is something I’ve worked on before, especially when preparing datasets for CRM imports and marketing automation systems. For your list of ~130,000 emails, I will run a full verification sweep using a trusted verification platform (such as NeverBounce or ZeroBounce) to check syntax validity, domain status, mailbox existence, disposable/role addresses, and potential spam trap risks—without sending any actual emails. You will receive two clean CSV files: • Valid & Safe – ready for import and sending • Invalid / Risky – including the specific reason each address failed verification I will also provide a summary report showing total records processed, percentage removed, and the projected bounce rate. Your original IDs and column structure will be preserved so the results can be merged back into your CRM without issues. Processing a list of this size is straightforward, and I can realistically complete the verification and deliver the files within 48 hours. Looking forward to helping you clean the list and improve your deliverability for future campaigns. Best regards, Talha

@MarcusCMP

Hey — saw your post about verifying 130k email addresses. With a list that size, the big risk is ending up on blocklists or wrecking your sender reputation if the verification isn’t done carefully. Quick question before I suggest an approach: Are these emails from a single source (like one lead gen funnel/CRM), or mixed from multiple sources over time? I’ve handled large-scale email hygiene and verification before, including reducing bounce rates and keeping domains out of spam traps and blocklists. If you share a sample of the list and your current sending setup (ESP, domain, volumes), I can review it and tell you what’s realistic in terms of accuracy and timeline.

@zeldac1

Hi there, I read your post about a 130k email list with soft and hard bounces and your goal of full deliverability verification, not just stripping bounces. Quick insight: a common trigger is outdated verification rules or domain-level blocks that misclassify addresses. Here’s my plan: • run a thorough sweep with a trusted verifier (SMTP-ping style) that doesn’t send real messages • preserve IDs and column order for CRM merging • return two CSVs named “Valid & Safe” and “Invalid / Risky” with reasons per bad address • include a brief summary: removal percentage and projected bounce rate • deliver a merge-ready result within your 48-72 hour window. I’ve cleaned 200k+ records for a retail client with a sub-2% bounce rate after verification. Best regards, Thando

@mutahrar

Hello, I am an email deliverability specialist with extensive experience cleaning large lists of 100,000+ addresses using industry-leading tools like ZeroBounce, NeverBounce, and MillionVerifier. I will run a comprehensive verification sweep on your 130,000 emails, checking for syntax errors, domain validity, mailbox existence via SMTP handshakes, role-based accounts, disposable addresses, spam traps, and catch-all domains—without sending a single actual message . Using a trusted platform like ZeroBounce, which processes bulk lists quickly with high accuracy and provides clear "valid," "invalid," and "catch-all" buckets, I will ensure every address is thoroughly vetted to raise your overall deliverability . I will return two clearly labeled CSV files—one "Valid & Safe" ready for CRM import, and one "Invalid / Risky" with specific failure reasons for each rejected address—while preserving your existing column order and IDs for seamless merging. A summary report will show the percentage removed and projected bounce rate, which I will test with a sample to confirm it stays below 2%. I can commit to a 48-hour turnaround and have successfully handled similar large-scale projects, ensuring you can send confidently. I am ready to begin as soon as you share the file.

I can complete this within 48–72 hours. I look forward to working with you and hopefully building a long-term collaboration. Best regards
