I need a fresh, fully-verified list of 100,000 B2B email contacts that point exclusively to the Yahoo Business (Turbify) MX record—login.turbify.com. All addresses must be active, deliverable and sourced from companies based in the United States. Scope • Industries: Construction, Mining and Oil&gas only. • Job titles to capture: CEO/Owner, Accounts Payable and Accounts Receivable. • Verification: every address must show the correct MX record and pass real-time validation; hard bounces or outdated data will void payment. Deliverables • CSV or XLSX file containing: email, full name, company, industry, job title, city/state, phone (if available). • A brief verification report outlining the tools or steps used to confirm the MX record and deliverability. Acceptance Criteria • Minimum 98 % deliverability on my test send. • 100,000 unique records meeting all filters above. • No generic catch-all addresses; each contact must match the requested titles. Milestone funds are released only after I confirm the list meets these benchmarks, so accuracy is essential.

Hi, this is fundamentally a data quality and verification problem, not just list building, and that distinction matters if you want 100,000 usable records tied specifically to Yahoo Business MX domains. The real engineering risk is false confidence in validation: MX checks, SMTP-style verification, title matching, and catch-all detection can each pass independently while the final dataset still fails a live send threshold. I’ve built production workflows where the important part is separating sourcing, normalization, verification, and acceptance auditing so the output is defensible. For a job like this, I usually structure the pipeline around domain qualification first, then contact-role resolution, then deduplication, then final deliverability scoring with an audit trail. The closest relevant work here is HubSpot CRM Implementation & Interactive Senior Living Website, where contact integrity and downstream usability mattered, along with Custom Feature Development & Integration for validation-oriented workflow design. I would recommend treating the CSV/XLSX export as the last step, not the product itself. The product is the verification ledger: why each record qualified, what MX was observed, whether catch-all behavior was excluded, and what confidence threshold was used before release. If useful, I can sketch the verification architecture and acceptance logic before any data collection starts. Thanks, Hercules

Hello, "Verified Yahoo Business Email Harvest" - need 100k verified Yahoo business contacts I will combine targeted web‑scraping with MX‑record verification (using MXToolbox API) to collect only CEO/Owner, Accounts Payable and Accounts Receivable contacts from US construction, mining and oil & gas firms. I delivered a similar 200‑lead list for Polish dental clinics with full verification: https://www.freelancer.com/projects/data-collection/Polish-Dental-Clinics-Business-Leads/reviews I will also handle rate‑limit throttling and filter out any catch‑all domains to keep deliverability above 98 %. Do you have a preferred template for the verification report? Looking forward to working with you. Artur Giżycki
