How every integration works

  1. Export or connect Export your contacts as a CSV from your tool, or call the Mailcut API from an automation such as Zapier or n8n.
  2. Verify with credits Upload the file or send the address. Each address uses one credit, and a repeated address in the same file is counted once.
  3. Import the clean list Download the result and import the valid addresses back. Invalid and disposable ones stay out; accept-all and unknown results are flagged for you to decide.

Credits are valid for 12 months and there is no subscription, so you can clean a list once and come back when you need to. New accounts start with free credits.
