I need a reliable data miner to collect fresh, accurate contact details—primarily email addresses and phone numbers—for a campaign I’m preparing. The sources can range from company websites and public online directories to any other open-web resources you find effective; what matters most is that the data is up-to-date and verifiable. Please scrape, clean, and de-duplicate the records, then deliver everything in a neatly formatted Excel or CSV file with separate columns for name (when available), email, phone, source URL, and the date you captured the data. I will provide the target industries, locations, or any other filters once we begin, so a flexible approach to gathering leads is essential. Before we start, let me know: • The tools or scripts you plan to use • Your typical verification process to reduce bounces and invalid numbers • An estimated timeframe for the first batch of leads My goal is quality over sheer volume, so accuracy checks and transparent sourcing will be key to approval.

Targeted lead mining with bounce-rate validation is something I handle regularly, and the quality-first framing here aligns exactly with how I work. 1. What defines a "qualified" record for this campaign — is a lead valid if it has either an email or a phone number, or do you need both fields populated on the same row? 2. Are the target contacts individual decision-makers (with job titles) or general company-level addresses like info@ or sales@, since that changes the sourcing strategy significantly? 3. What bounce or invalid-number threshold is acceptable to you before a batch gets rejected — knowing this upfront lets me calibrate verification depth against turnaround speed? 4. Are there any industries, regions, or data-privacy jurisdictions (GDPR-covered EU contacts, for example) that would restrict how the data can be collected or stored on your end? Share those details and I can map out a precise sourcing and verification workflow before we touch a single record.

You want up to date, verifiable emails and phone numbers that actually reach people, not role inboxes or stale directory entries—got it. Most lists fail because they skip MX and carrier checks and never record where and when a contact was captured. That’s what causes bounces and bad outreach metrics. I built the scraper and cleaning pipeline for Skaly where we pulled restaurant owner contacts from sites and directories, deduped and delivered ready to use CSVs. Approach 1. Build target list from your filters 2. Scrape company sites directories and public profiles with Python scripts and Selenium where needed 3. Clean and dedupe then verify emails and phones 4. Deliver CSV with name email phone source_url date_captured and brief QA notes Tools and scripts I use Python requests BeautifulSoup Selenium plus small utility scripts. Verification I run regex and MX checks SMTP probe plus libphonenumber for normalization and carrier validation and a sampling of manual checks to catch edge cases. Typical timeframe I can deliver a first sample batch of 100 verified leads in 48 to 72 hours depending on targets. Which industry location and decision titles should I start with? I can prepare a 25 lead sample CSV for your review.
