About
Email List Validation checks uploaded address lists and provides real-time verification through an API. Users can upload CSV or TXT files, import from integrations and download selected result groups. Checks include syntax, domains, MX records, SMTP responses, duplicate removal and role-address identification, with retry handling for greylisting.

The service supports shared team credits and integrations with marketing tools such as HubSpot, ActiveCampaign, Mailgun and SendGrid. Automated cleaning and webhooks connect verification to ongoing workflows. Inbox placement reports and blocklist monitoring are separately priced tools, so their availability should be distinguished from ordinary verification credits.
One credit checks one address through the dashboard, upload or API. Pay-as-you-go credits do not expire, and monthly allocations are also offered. The published minimum purchase is 2,500 credits, with 100 credits provided for initial testing. Users can download results by category to prepare a cleaned list.
Duplicate addresses within an uploaded list are removed before verification, so they do not consume a second credit.
