Available actions

## 865 actions your agents can run in MailerCheck

- Create Verification List  
Create a MailerCheck verification list by ingesting a name and email-address array. Creating a one-address list did not reduce the account credit balance during live probing. This action does not invoke the separate, credit-consuming Start List Verification operation.
- Delete Verification List  
Permanently and irreversibly delete a MailerCheck verification list by ID. Use only when the caller explicitly intends to remove the list.
- Get Credit Balance  
Return the current MailerCheck verification-credit balance. Use this before VERIFY\_EMAIL or START\_LIST\_VERIFICATION when cost matters.
- Get Current Account  
Return the connected MailerCheck user and account identity. Use this to confirm which user and account the API token represents.
- Get Verification List  
Return one verification list, including its status, item count, verification timing, and aggregate result statistics.
- List Verification Lists  
Return one page of verification lists for the connected MailerCheck account, with an opaque cursor when another provider-controlled page exists.
- List Verification Results  
Return one page of email-level results for a verification list, optionally filtered by classification. The success envelope and pagination behavior are based on MailerCheck documentation and were not live-verified because producing results requires a credit-consuming list verification.
- Start List Verification  
Irreversibly start verification of every address in a MailerCheck list. A successful call spends one verification credit per address. Before calling, use GET\_VERIFICATION\_LIST to inspect the list count and GET\_CREDIT\_BALANCE to confirm the current credit\_balance. This endpoint was not live-executed…
- Verify Email  
Consumes exactly one MailerCheck verification credit on every successful call. Synchronously verify one email address and return its classification; check GET\_CREDIT\_BALANCE first if cost matters.
