With 300M+ verified professional profiles across 30M+ companies, 143M verified emails, 125M+ verified mobile numbers, and a 98% email accuracy rate backed by a proprietary 5-step verification process, Prospeo gives revenue teams a single trusted source of contact data at a fraction of legacy vendor pricing.\n\nFind Your Exact ICP in Seconds\n\nProspeo's People and Company Search lets teams build precise lead lists using 30+ filters — job title, seniority, department, location, company size, revenue, industry, tech stack, funding stage, headcount growth, and buyer intent signals. Results are sorted by likelihood to purchase so reps focus on accounts most likely to convert. Buyer intent data surfaces companies actively researching your category before they engage a competitor. Job Change Tracking alerts you the moment a key decision maker moves companies so you reach them at exactly the right time. Duplicate Control prevents the same contact from appearing twice across searches and exports.\n\nVerify Every Contact Before You Pay\n\nEvery email passes through syntax checking, domain validation, catch-all server detection, spam-trap and honeypot removal, and SMTP confirmation before it reaches you. Credits are only charged for verified results. If Prospeo cannot confirm a valid email or mobile number, no credit is spent. The full database refreshes every 7 days so exported contacts reflect current reality and not stale records from months prior. Average bounce rate on verified Prospeo emails is under 2%.\n\nEnrich Any List You Already Have\n\nCSV Enrichment turns incomplete data into outreach-ready contact lists in minutes. Upload any file starting with a name, company, LinkedIn URL, or work email and Prospeo fills in verified emails, direct dials, job history, company data, and 40+ additional data points automatically. The same engine powers native CRM enrichment for HubSpot and Salesforce, running on-demand or automatically in the background to keep records accurate without manual work. Duplicate detection and match-and-merge prevent data conflicts across your CRM.\n\nCapture Leads Anywhere You Work\n\nThe Prospeo Chrome Extension works on any webpage, social profile, or company website. Open it on any profile to reveal a verified email and direct dial instantly. Open it on a company website to view the entire team, filter by department or seniority, and push selected contacts straight into your CRM or outreach sequences without switching tabs. Used by 40,000+ sales professionals with a 4.8 rating.\n\nReal Results Across Every Team\n\nSales teams cut list-building time from hours to minutes and book more meetings without adding headcount. One SDR went from 60% to 140% of quota in a single quarter after switching to Prospeo. RevOps teams standardize data quality, protect sender reputation, and keep CRM records current automatically. GreyScout recovered flagged domains and scaled from 2 to 5 reps in 90 days, with bounce rates dropping to under 4% and pipeline increasing 140%. Founders test ICPs fast and scale outbound without burning runway. Meritt tripled weekly pipeline from $100K to $300K with the same team.\n\nIntegrate With Your Full Stack\n\nNative integrations with HubSpot, Salesforce, Salesloft, Lemlist, Instantly, Smartlead, and Outreach.io mean verified leads flow directly into existing workflows. API integrations with Clay, Zapier, n8n, and Make.com support custom enrichment pipelines at any scale. The REST API includes search and enrichment endpoints with sub-second response times and 99.99% uptime.\n\nTransparent Pricing, No Contracts\n\nProspeo is fully self-serve. A free plan includes 100 credits per month, forever. Paid plans start at $49 per month for 2,000 credits.","image":"https://gdm-catalog-fmapi-prod.imgix.net/ProductScreenshot/93df1f39-ea32-4e03-ad5f-a67cba43acce.webp","url":"https://www.getapp.sg/software/2084770/prospeo-email-verifier","@type":"SoftwareApplication","@id":"https://www.getapp.sg/software/2084770/prospeo-email-verifier#software","publisher":{"@id":"https://www.getapp.sg/#organization"},"applicationCategory":"BusinessApplication","aggregateRating":{"@type":"AggregateRating","bestRating":5,"ratingCount":280,"ratingValue":4.8},"offers":{"price":"0","@type":"Offer","priceCurrency":"USD"},"operatingSystem":"Cloud, Apple, Windows"},{"@type":"BreadcrumbList","@id":"https://www.getapp.sg/compare/117675/2084770/mailfloss/vs/prospeo-email-verifier#breadcrumblist","itemListElement":[{"name":"Home","position":1,"item":"/","@type":"ListItem"},{"name":"Email Validation Tools","position":2,"item":"/directory/1469/email-verification-tools/software","@type":"ListItem"},{"name":"mailfloss vs Prospeo","position":3,"item":"https://www.getapp.sg/compare/117675/2084770/mailfloss/vs/prospeo-email-verifier","@type":"ListItem"}]}]}
