MailPattern

MailPattern is an email lookup tool that identifies professional email addresses from a dataset of 2.2 million real email patterns across 1.68 million company domains. Given a person's name and company domain, it finds the company's email pattern and shows a transparent confidence score — indicating low confidence instead of guessing when data is insufficient. Single lookups on the homepage are unlimited and free, with no registration or credit card required. A bulk lookup tool processes CSV files (free accounts get 200 rows per month), and paid plans verify each address against the real mail server via MillionVerifier, returning Valid, Invalid, Risky, or Catch-all statuses. A Chrome extension adds the same lookup to LinkedIn profiles and company websites. GDPR compliance is maintained by not storing searched emails.

SimpleVerifier

SimpleVerifier checks each email address the way a mail server would: it connects to the recipient's server, asks whether the mailbox exists, then disconnects before anything is sent. Upload a CSV or check one address, and every row comes back valid, risky or invalid with the reason and send advice. Valid means the mail server confirmed the mailbox. Catch-all domains, role addresses and providers that hide mailbox status stay risky, never guessed valid, and catch-alls are graded higher, medium or lower likelihood with the reasons. It also flags disposable domains, typos and duplicates, and checks MX, SPF, DKIM, DMARC and blocklists for your sending domains. Pricing is monthly, not credits. Starter is $9 a month for 2,500 checks. Pro is $39 a month with no cap and no per-email fees. Fair use: the first 100,000 checks a month run at full speed, then big lists run in a paced lane, never cut off. Business ($99) and Agency ($249) raise the full-speed volume to 300,000 and 750,000 a month and add 5 or 15 seats, a priority lane, and on Agency, client workspaces and branded client reports. One-time packs start at $15 for 10,000 checks and never expire. The first 100 checks are free with a Google sign-in, no card. Cancel anytime; fees are non-refundable once charged. Pro and up add an email finder and website enrichment (fair use), a REST API (10,000 calls a month on Pro, then $1.50 per 1,000) and a remote MCP server so agents in Claude, ChatGPT, Cursor and VS Code can verify addresses directly. It connects to Instantly, Smartlead, HubSpot and Mailchimp by API key and tags each contact with its result. Phone numbers get a free format and number-type check; Pro + Phone ($49.99 a month) adds 5,000 live carrier lookups a month. What it doesn't do: no sending, no warm-up, no inbox placement tests.

Valid Email Checker

Valid Email Checker is an email verification and list-cleaning platform built for marketers, agencies, e-commerce teams, and developers who rely on email. It removes invalid, risky, and low-quality addresses from your lists so your campaigns reach real inboxes — cutting bounce rates, protecting your sender reputation, and improving deliverability. Every address is checked through our own 11-stage verification flow: syntax validation, MX record lookup, SMTP handshake, mailbox-existence probe, catch-all detection, role-account detection, disposable and temporary-address detection, spam-trap detection, full-mailbox detection, and disabled-account detection. Each result returns a clear status, a 0–100 risk score, and a deliverability rating, so you know exactly which contacts are safe to send to and which to hold back. What sets Valid Email Checker apart is how it handles uncertainty. If an address can't be conclusively verified and comes back "unknown," the credit is automatically refunded — no support ticket, no fine print — and recorded in your credit history. Most verifiers quietly charge you for those inconclusive results. We don't, so you only ever pay for answers you can act on. Verify a single address in under a second, or upload an entire list for bulk verification. Lists of any size — from a few hundred addresses to very large files — are processed reliably from start to finish, and any contacts that have already unsubscribed are skipped automatically, so you're never charged to re-verify them. Valid Email Checker also connects to the tools you already use. Choose from 17 native one-click integrations with leading email marketing and CRM platforms — including Mailchimp, Klaviyo, HubSpot, Brevo, MailerLite, ActiveCampaign, and SendGrid — or automate verification through Make, n8n, and Integrately. Developers can plug directly into the REST API to validate addresses in real time at signup or anywhere inside their own applications. Getting started is simple: every new account includes 150 free credits, with no credit card required. From there, choose pay-as-you-go credits that never expire, or a monthly plan for regular senders. Card and cryptocurrency payments are both supported.
