MailValid

MailValid is a real-time email verification API and bulk list-cleaning tool that checks whether an email address is valid, invalid, catch-all, disposable, or role-based before you send. Each address is verified through syntax (RFC 5322), MX/domain lookup, and SMTP mailbox confirmation in under 500ms, with 95%+ accuracy and 99.9% uptime.. No test email is sent. Use it three ways: a no-code dashboard for CSV uploads, a REST API for real-time checks at signup or checkout, or a hosted MCP server so AI agents (Claude, Cursor) can verify emails as a tool call. Pricing starts at $0.0015/email (Starter) and drops to $0.0006/email at scale. Credits never expire on any plan, including the 100 free signup credits. Built for cold email agencies, SaaS signup verification, RevOps/CRM list hygiene, and e-commerce checkout validation.

SafeToSend

Undeliverable and harmful addresses can lead to blocking and blocklisting by ISPs, which can bring an email marketing program to a grinding halt. FreshAddress’s SafeToSend service provides comprehensive protection against costly problematic addresses. The payoff is substantial: 100% guaranteed safe, deliverable email addresses that drive higher response rates, conversions, and profits. The differences between FreshAddress’s SafeToSend® email hygiene, correction, and validation service and the email validation services offered by the other providers in our industry are like night and day. Other email hygiene providers primarily perform an email ping (or SMTP check) to try to determine if an email address is bouncing or deliverable. Email pinging is not a perfect science and the process provides highly inaccurate results for Verizon Media, formerly known as Oath (Yahoo, AOL, and Verizon), accept-all domains, and some other ISPs that have technologies in place to block email pingers. FreshAddress’s SafeToSend service, on the other hand, is comprised of three components: Hygiene, Correction, and Validation as follows: Hygiene: Flag deliverable but problematic email addresses, including spamtraps, honeypots, heavy spam complainers, role accounts (e.g. abuse@, sales@, tech@, etc.), FCC’s Wireless Domain Blocks, the DMA’s “Do Not Email” suppressions, and other email addresses, all of which will “ping” as deliverable but will likely get your email campaigns blocked or blocklisted. No other provider has the expertise, experience, technology, or knowledgebase to identify these deliverable but toxic email addresses. Correction (i.e. “spell-check for email addresses”): Identify and correct syntax, typo, formatting, misspelling, and other top level domain errors. Having analyzed billions of email address registrations, FreshAddress’s “spell-check for email” correction functionality can correct the vast majority of email address errors made, thereby allowing you to reconnect with a customer/prospect you would have otherwise lost. FreshAddress’s patented “spell-check” technology is included in our original Email Change of Address patent, which was issued in 2003. FreshAddress has analyzed over 10 billion email address registrations and can identify and correct the vast majority of inadvertent hygiene errors made upon opt-in. No other provider can correct email hygiene errors anything more than the most basic hygiene errors. Validation: Validate the deliverability of all email addresses that survive the first two screens, including validating the deliverability of our corrections. FreshAddress’s validation component first relies on its ESP Reporting Network, which contains email-specific information including delivered, bounced, open, click-through, opt-out, and spam complaints on over 10 billion deployments. In addition, it performs real-time SMTP checks (i.e. the “ping” that all other companies basically do), other proprietary technology and processes to check the validity of an email address, and archives its real-time SMTP checks to double-check its real-time data for accuracy and consistency. FreshAddress also utilizes purchase activity data to further inform the Validation component of its SafeToSend service. No other provider has access to email-specific activity and purchase activity data to inform their results, their email pinging technology cannot provide accurate results for Verizon Meida/Oath (Yahoo, AOL, and Verizon) or accept-all domains, and they lack the technology, expertise, and additional data to override real-time ping results when these are clearly inaccurate.

Boring Plugins

At Boring Plugins, we’re here to make sales development easier—and measurably more productive. As former SDRs, we know how frustrating it is to find a great prospect, only to have an email bounce or a workflow slow you down. That’s why we make it impossible for your emails to bounce and easier to get in front of more prospects: Verify automatically checks emails in your SDR flow before you use them, and helps you find a better address when one isn’t valid; Export generates new, ready-to-contact prospects with live emails; and Dial turns Outreach’s dialer into a power dialer so reps can call with speed. Because it all lives inside the tools your team already uses, there’s nothing new to learn—just more connects, more meetings, and more pipeline from the same team.

Enrow

Enrow is a B2B contact data platform that finds and verifies professional email addresses and direct mobile phone numbers in real time, so sales, marketing and recruiting teams can reach decision-makers instead of bouncing off dead inboxes and disconnected lines. Most sales intelligence and lead enrichment tools resell the same static database, which starts ageing the day it is compiled. Enrow deliberately has no searchable contact database. Every lookup runs live at the moment you ask, then passes through more than ten verification checks — catch-all domains included — before a result is returned. When no deliverable address exists, Enrow returns nothing rather than a low-confidence guess. Teams running Enrow typically keep bounce rates under 1%. Three products share one credit pool: Email Finder — a name and a company in, a verified professional email out, in about two seconds. Billed only when an address is actually found. Email Verifier — a deterministic valid or invalid verdict on any list, with catch-alls resolved rather than flagged, at a quarter of a credit per check. Direct Phone Finder — mobile numbers that ring the person whose name is on the record. No landlines, no switchboards. Use them wherever you already work: a free Chrome extension that turns a LinkedIn or Sales Navigator profile into a complete, verified CRM record in one click; native integrations with HubSpot, Salesforce, Pipedrive, Attio, Clay, Smartlead, lemlist, Instantly, Zapier, Make and n8n; CSV upload for bulk list enrichment; an official MCP server for Claude, ChatGPT and AI agents; and a REST API with single and bulk endpoints, async jobs and webhook delivery for GTM engineers building enrichment waterfalls. Pricing follows one principle: pay for results, not for seats or searches. A miss costs nothing — not a credit, not a partial credit — so the sticker price is the real cost per valid contact. Credits are shared across all three products and roll over. Unlimited team members are included from Pro upward, so a five-person team pays one price instead of five. Plans start at €15/month, with no contract, no onboarding call and no mandatory demo. Enrow is fully GDPR and CCPA compliant, with a published Data Processing Agreement, a documented sub-processor list and an opt-out request process for data subjects. Enrow is built for SDRs and account executives, founders prospecting without a sales team, growth and RevOps teams cleaning CRM data, lead generation agencies, recruiters sourcing passive candidates, and GTM engineers who need a data provider that behaves predictably at API scale. Every account starts with 50 free credits, no credit card required.
