Prime Verifier
Verify every email with confidence.
Prime Verifier is an email verification and list cleaning platform. It checks whether an email address can receive mail through layered validation: syntax, domain MX records, a live SMTP check with the receiving mail server, disposable email detection, catch-all probing, and risk scoring. It supports single lookups, bulk CSV uploads, a REST API, webhooks, and streaming bulk processing. The platform integrates directly with 13 tools (Mailchimp, HubSpot, Klaviyo, Google Sheets, Zoho CRM, ActiveCampaign, SendGrid, Brevo, MailerLite, Campaign Monitor, Mailgun, Mailjet, SparkPost) and via Zapier with 9,000+ apps. It also offers an MCP server for AI agents. Pricing is per credit: one credit verifies one email address. Unknown results (catch-all, unknown, errors) are free. Credits never expire. There is a pay-as-you-go one-time top-up and a monthly subscription with an 8% discount. A free tier provides 100 credits with no credit card required.
