Emailvalidation

Validate individual email addresses for deliverability and quality signals, and inspect account quota usage through emailvalidation.io's complete REST API surface.

What agents can do

Actions2

  • Get account quota status

    Return the connected emailvalidation.io account ID and current monthly and grace credit totals, usage, and remaining balances.

  • Validate email address

    Validate one email address and return deliverability, format, mailbox, domain, role-address, disposable-address, and quality signals.

How it connects

You paste an API key from Emailvalidation on a page Composio hosts, so the key never passes through Definable.

Keep the connection to yourself or share it with your workspace. Any action that writes or sends can wait for your approval.
