Actions3
Check domain health
Check a bare domain's SPF, DKIM, DMARC, and BIMI configuration and return protocol scores plus provider recommendations.
Validate email
Validate one non-empty email address and return its overall validity plus syntax, MX, spoofing, and disposable-address signals.
Validate emails
Validate 1-10 email address strings in one synchronous request and return one ordered result per input, including malformed strings as invalid results.
How it connects
You paste an API key from Verifi.Email 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.
