About

MailPattern is a B2B email finder and verification tool. Given a contact's name and company domain, it identifies the company's email pattern from a dataset of 2.2M verified patterns across 1.68M domains, generates the address, and shows a confidence score. When there isn't enough data, it says so instead of guessing. Single lookups on the homepage are unlimited and free, with no sign-up required, and include mail-server verification (Valid, Invalid, Risky, or Catch-all). A Chrome extension adds the same lookup to LinkedIn profiles, and a bulk tool processes CSV lists — free accounts get 200 rows per month. Paid plans are one-time payments (1, 3, 6, or 12 months of 500–1,200 verified rows/month) rather than subscriptions, with no auto-renewal.

About

ReachStream Email Verifier helps businesses validate individual email addresses and email lists before outreach. Sales and marketing teams can check addresses through the web dashboard or upload a CSV list, then use the results to identify potentially invalid contacts and improve contact data quality. The service supports email list validation, prospect-list cleanup, and preparation for sales and marketing campaigns. It is designed for B2B sales teams, marketers, lead-generation specialists, and other organizations that rely on email outreach. An API supports automated verification, and an MCP connector lets users access email verification from Claude. By identifying potentially invalid addresses before a campaign, ReachStream Email Verifier can help users reduce unnecessary bounces, maintain cleaner contact lists, and support email deliverability.
