MailCull

MailCull is an email verification service built for people who send real email and get blamed when a list bounces. We started it because every email validator we tried as customers gave back a one-word verdict, "valid" or "invalid," and refused to explain it. When an address we paid to verify still hard-bounced, we had nothing to show for it. So we built the tool we wished existed: one where every check is a line item, every line item is in plain English, and every verdict comes with a receipt. That receipt is the difference. For every address, MailCull returns one of four clear states, deliverable, risky, undeliverable, or unknown, along with the evidence behind it: the actual SMTP reply from the receiving server, the MX record, the reason codes, and a confidence score. A deliverable is one you can defend to a client. A risky tells you why it is risky, usually a catch-all or accept-all domain, instead of quietly marking it valid and letting it bounce at send time. You can verify a full list by uploading a CSV, or check a single address on the spot. Deep scan probes mailboxes at the SMTP level for a sharper verdict, and it is included on the free plan rather than locked behind an upgrade. An AI Analyst reads the evidence for any result and explains the conclusion in a sentence, so you do not need a deliverability background to act on it. We measure real-world accuracy honestly, in the 91 to 93 percent range, and we publish the methodology rather than claiming a round 99 percent. Pricing is deliberately simple: one flat price, a unified monthly credit pool, no per-pack math, no surprise overages, and no charge for unknowns. There is a developer API and a first-party MCP server, so verification fits into your own app or into AI tools like Claude and Cursor. MailCull is small, opinionated, and focused on one job: helping you send to addresses that actually exist, and showing you the proof.

Mailerio

Mailerio is built by a couple who launched their first SaaS, Ajelix, in 2022. Over the years, they struggled with email deliverability: emails landed in spam, bounce rates exceeded thresholds, customers couldn't receive confirmation emails, and it hurt their business. So, they built an email validation tool for internal use that solved the issue, achieving an average open rate of 65% and reducing their bounce rate to 0.2%. That’s when they realized that if they had this problem, others likely did too, so they launched Mailerio for public access.

MailinBox

MailinBox is the most accurate and reliable email validation service to protect your email reputation. It offers a variety of tools that can help you reach 99% verification accuracy: bulk email list verification, a powerful verifier API, cross-platform integrations, automated email campaigns, and more.

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.
