SimpleVerifier
SimpleVerifier
SimpleVerifier is a hosted email verification service for teams preparing contact lists for outreach, marketing, or lead generation. Users can check one address or upload a CSV for batch processing. Email checks evaluate syntax and mail routing, then probe recipient servers using SMTP without sending a message. Each row returns valid, risky, or invalid with a reason. Catch-all domains, role addresses, and providers or servers that do not confirm mailbox status remain risky rather than being guessed valid. It also checks phone number format and type. Higher-tier plans include email finding and website enrichment, and the API is available on Pro, Business, and Agency plans. Integrations include Instantly, Smartlead, HubSpot, and Mailchimp. Monthly plans cover different list volumes, and the first 100 email checks are free after Google sign-in. SimpleVerifier serves outbound emailers, lead-generation agencies, marketers, and developers who clean lists before campaigns.Starting Price: $9/month -

It can help teams identify addresses that may be invalid or risky before sending or storing email lists. The product is also offered through extensions and add-ons, a self-hosted HTTP API, an MCP server, and language libraries for incorporating the same checks into other workflows.Starting Price: Free -

charlymail
charlymail
charlymail is an email verification and lead data platform built for people who send at volume: cold outreach teams, affiliate marketers and lead-generation agencies. • VALIDATE — syntax, domain, MX records, role addresses, disposable domains, catch-all detection • SMTP — a deep check that opens a conversation with the receiving mail server and confirms the mailbox exists, without sending any message • ENRICH — name, gender, country, provider and corporate/personal classification • COLLECT — scrape addresses by niche from public sources Most services charge full price for every address in your file, including the obviously broken ones. charlymail splits the work.

Addresses verified recently come back from cache for free. -

Company lookup takes a domain and returns up to 20 verified addresses at that organization. LinkedIn lookup extracts the email behind any LinkedIn profile URL. Decision maker lookup finds the right person by role — CEO, CTO, Head of Marketing, VP Sales, and more. The API is simple. Standard REST with GET requests and Bearer token authentication. -
