Agent Mail Lists

Blocks for managing allow/block lists in AgentMail. Lists let you control which email addresses and domains your agents can send to or receive from, based on direction (send/receive) and type (allow/block).

Agent Mail Create List Entry

What it is

Add an email address or domain to an allow/block list. Block spam senders or whitelist trusted domains.

How it works

This block calls the AgentMail API to add an email address or domain to a specified list. You select a direction ("send" or "receive") and a list type ("allow" or "block"), then provide the entry to add. For block lists, you can optionally include a reason such as "spam" or "competitor."

The API creates the entry and returns both the entry string and the complete entry object with metadata. Any errors propagate directly to the global error handler.

Inputs

Input	Description	Type	Required
direction	'send' for outgoing email rules, 'receive' for incoming email rules	"send" \| "receive"	Yes
list_type	'allow' to whitelist, 'block' to blacklist	"allow" \| "block"	Yes
entry	Email address ([email protected]) or domain (example.com) to add	str	Yes
reason	Reason for blocking (only used with block lists, e.g. 'spam', 'competitor')	str	No

Outputs

Output	Description	Type
error	Error message if the operation failed	str
entry	The email address or domain that was added	str
result	Complete entry object	Dict[str, Any]

Possible use case

Spam Prevention — Block a known spam domain so your agent never processes incoming messages from it.

Trusted Partner Allowlisting — Add a partner's domain to the receive allow list so their emails always reach your agent.

Outbound Restriction — Add a competitor's domain to the send block list to prevent your agent from accidentally emailing them.

Agent Mail Delete List Entry

What it is

Remove an email address or domain from an allow/block list to stop filtering it.

How it works

This block calls the AgentMail API to remove an existing entry from an allow or block list. You specify the direction, list type, and the entry to delete.

On success the block returns success=True. If the entry does not exist or the API call fails, the error propagates to the global error handler.

Inputs

Input	Description	Type	Required
direction	'send' for outgoing rules, 'receive' for incoming rules	"send" \| "receive"	Yes
list_type	'allow' for whitelist, 'block' for blacklist	"allow" \| "block"	Yes
entry	Email address or domain to remove from the list	str	Yes

Outputs

Output	Description	Type
error	Error message if the operation failed	str
success	True if the entry was successfully removed	bool

Possible use case

Unblocking a Sender — Remove a previously blocked domain after confirming it is no longer a spam source.

Revoking Access — Delete a domain from the receive allow list when a partnership ends and messages should no longer be accepted.

Policy Correction — Remove an entry that was added by mistake so normal email flow resumes immediately.

Agent Mail Get List Entry

What it is

Check if an email address or domain is in an allow/block list. Verify filtering rules.

How it works

This block queries the AgentMail API to check whether a specific email address or domain exists in an allow or block list. You provide the direction, list type, and the entry to look up.

If the entry is found, the block returns the entry string and the complete entry object with metadata (such as the reason it was added). If the entry does not exist, the error propagates to the global error handler.

Inputs

Input	Description	Type	Required
direction	'send' for outgoing rules, 'receive' for incoming rules	"send" \| "receive"	Yes
list_type	'allow' for whitelist, 'block' for blacklist	"allow" \| "block"	Yes
entry	Email address or domain to look up	str	Yes

Outputs

Output	Description	Type
error	Error message if the operation failed	str
entry	The email address or domain that was found	str
result	Complete entry object with metadata	Dict[str, Any]

Possible use case

Pre-Send Validation — Check whether a recipient domain is on the send block list before your agent drafts an outbound email.

Audit Verification — Look up a specific address to confirm it was added to the block list and review the recorded reason.

Conditional Routing — Check the receive allow list for a sender's domain to decide whether to process the message or skip it.

Agent Mail List Entries

What it is

List all entries in an AgentMail allow/block list. Choose send/receive direction and allow/block type.

How it works

This block retrieves all entries from a specified allow or block list by calling the AgentMail API. You select a direction and list type, and optionally set a page size with limit and continue paginating with page_token.

The API returns the list of entry objects, a count of entries in the current page, and a next_page_token for fetching additional results. Any errors propagate to the global error handler.

Inputs

Input	Description	Type	Required
direction	'send' to filter outgoing emails, 'receive' to filter incoming emails	"send" \| "receive"	Yes
list_type	'allow' for whitelist (only permit these), 'block' for blacklist (reject these)	"allow" \| "block"	Yes
limit	Maximum number of entries to return per page	int	No
page_token	Token from a previous response to fetch the next page	str	No

Outputs

Output	Description	Type
error	Error message if the operation failed	str
entries	List of entries, each with an email address or domain	List[Dict[str, Any]]
count	Number of entries returned	int
next_page_token	Token for the next page. Empty if no more results.	str

Possible use case

Policy Dashboard — Fetch all entries on the receive block list to display a management view where administrators can review and remove entries.

Periodic Cleanup — Page through the full send allow list to identify stale entries that no longer correspond to active partners.

Compliance Export — Retrieve every block list entry across both directions to generate a report for an internal compliance audit.
