Tools

74 tools agents can invoke

Adds a new subscriber to a list and returns its subscriber_uid. Fails if the email is already in the list: use create_or_update_subscriber to add-or-update, or bulk_create_subscribers for many contacts at once. Depending on the list's opt-in setting the new subscriber may start as unconfirmed.
create_subscriber
Upsert: looks up data.EMAIL in the list; if found it updates that subscriber, otherwise it creates a new one. Use it to sync contacts when you do not know whether they already exist. Existing values are overwritten, so confirm with the user before updating real contacts.
create_or_update_subscriber
Stops a scheduled campaign before it starts by moving it back to draft; nothing is deleted and it can be scheduled again later. For a campaign that is already sending use pause_unpause_campaign. Confirm with the user first.
cancel_scheduled_campaign
Checks the public DNS records that decide whether a domain's email gets delivered: SPF (single record, ending, DNS lookups under the limit of 10, includes that no longer exist), DKIM (the most common selectors, or the one you pass in selector, with key length), DMARC (policy, reports address, inherited from the parent domain) and MX (which servers and spam filters receive the mail). Returns status (checked, public_mailbox, not_found, invalid, dns_unreachable), summary, checks.spf/dkim/dmarc/mx each with result (ok, fix, missing, check) and an explanatory note, tips ordered by priority with the exact values to publish, and the raw records. Works on any domain, does not need data from the MailSenpai account and changes nothing. Use it before sending from a new domain or when emails land in spam.
check_domain_dns
Checks whether a public IPv4 address or a domain is listed on the public email blocklists (DNSBLs) that MailSenpai queries. For a domain it checks the domain, its registered domain, the IPs of its MX servers and its A record. Returns status (done, in_progress), summary, counts (checks, listed, unreachable, clean) and, for each target, every list with result (listed, clean, unreachable), the reason and the list's official removal page. manual_checks holds the lists that are not queried (for example Spamhaus), each with the link to its official check page. Works on any IP or domain, needs no data from the MailSenpai account and changes nothing. Use it when emails bounce with a blocklist error or before sending from a new IP. It usually answers in 1-5 seconds; if status is in_progress, call again with the returned job.
check_blacklist
Same as confirm_subscriber, but first finds the subscriber by email in the given list. Re-subscribing someone who opted out requires their consent, so confirm with the user first.
confirm_subscriber_by_email
Sets a subscriber's status to confirmed by subscriber_uid: confirms an unconfirmed contact or re-subscribes one who unsubscribed, so they receive campaigns again. Do this only with the contact's consent and after the user confirms. Use confirm_subscriber_by_email if you only have the address.
confirm_subscriber
Duplicates an existing campaign (list, segment, content and settings) into a new DRAFT without send date and returns the new campaign_uid; the copy's name gets a "#1"-style suffix. Use it to reuse a past campaign; use create_campaign to start from scratch. Nothing is sent.
copy_campaign
Creates a copy of a list with its settings, custom fields and segments (subscribers are NOT copied) and returns the new list_uid; the copy's name gets a "#1"-style suffix. Use create_list instead to start an empty list from scratch.
copy_list
Creates a new campaign, by default as a DRAFT that sends nothing. Needs list_uid, name, subject, from_name, from_email, reply_to, send_at and content (template_uid or template_content HTML). To duplicate a past campaign use copy_campaign; to create and schedule in one step use create_scheduled_campaign. status=pending-sending schedules real sending and requires confirm_send=true after explicit user approval.
create_campaign
Adds a new custom field to a list (e.g. a "City" text field or a "Plan" dropdown) and returns it. Valid type identifiers come from list_list_field_types. Existing subscribers start with the new field empty.
create_list_field
Creates a new, empty mailing list and returns its list_uid. To duplicate an existing list with its custom fields and segments use copy_list instead; to add contacts afterwards use create_subscriber or bulk_create_subscribers.
create_list
Creates a saved segment in a list from field conditions (and optional campaign open/click conditions) and returns its segment_uid. Get field_id values from list_list_fields and operators from list_segment_condition_operators.
create_list_segment
Saves a new reusable email template from HTML (or a ZIP archive) and returns its template_uid, which create_campaign can use. It does not create or send any campaign.
create_template
Creates a campaign and schedules it for real sending in one step (status pending-sending at campaign.send_at). To prepare a draft for review use create_campaign instead. Ask the user to approve list, content and send time, then call with confirm_send=true (plus approval_reference if the plan requires it).
create_scheduled_campaign
Bulk-create subscribers in one list. Each row must contain EMAIL. The customer plan maxBulkImportRows limit is enforced.
bulk_create_subscribers
Permanently deletes a campaign and its statistics; this cannot be undone. To stop a campaign but keep it use cancel_scheduled_campaign or pause_unpause_campaign. Ask the user for explicit confirmation, then call with confirm_delete=true.
delete_campaign
Permanently deletes a custom field from a list, together with the values stored in it for every subscriber; this cannot be undone. Ask the user for explicit confirmation, then call with confirm_delete=true.
delete_list_field
Permanently deletes a mailing list together with all its subscribers, custom fields and segments; this cannot be undone. Ask the user for explicit confirmation, then call with confirm_delete=true. Only available if the plan allows deletions.
delete_list
Permanently deletes a saved segment; the subscribers themselves are kept. Ask the user for explicit confirmation, then call with confirm_delete=true.
delete_list_segment
Same as delete_subscriber, but first finds the address in the given list. Permanent; for a simple opt-out use unsubscribe_subscriber_by_email. Ask the user for explicit confirmation, then call with confirm_delete=true.
delete_subscriber_by_email
Permanently deletes a subscriber (by subscriber_uid) and its history from a list; this cannot be undone. To stop emails while keeping the record use unsubscribe_subscriber instead. Ask the user for explicit confirmation, then call with confirm_delete=true.
delete_subscriber
Permanently deletes a saved template; campaigns that already used it keep their content. Ask the user for explicit confirmation, then call with confirm_delete=true.
delete_template
Permanently deletes a transactional email record by email_uid; this cannot be undone. Ask the user for explicit confirmation, then call with confirm_delete=true.
delete_transactional_email
Finds an email address across ALL lists of the account and returns every match with its list, subscriber_uid and status. Use it when the list is unknown (e.g. privacy or opt-out requests); use search_subscriber_by_email when you know the list. Read-only.
search_subscriber_by_email_all_lists
Checks whether an email address is in ONE given list and returns its subscriber_uid and status; an error saying the subscriber does not exist means not found. Use search_subscriber_by_email_all_lists when you do not know the list. Read-only.
search_subscriber_by_email
Returns what the connected MailSenpai account may do: customer name, roles, permission scopes, the list UIDs it is restricted to (empty means all lists) and plan limits such as canSendCampaigns, canDelete, requiresApprovalForSend and maxPerPage. Call it first when you are unsure whether a write, send or delete action is allowed. Read-only, no parameters.
get_my_mailsenpai_capabilities
Returns one campaign by campaign_uid: name, subject, sender, list and segment, status and send date. For opens, clicks and bounces use get_campaign_stats. Read-only.
get_campaign
Returns the aggregate results of one campaign: recipients processed, delivered, opens and unique opens, clicks, hard/soft bounces, unsubscribes and complaints, with rates. For the individual bounce records use list_campaign_bounces. Read-only.
get_campaign_stats
Returns one custom field of a list by field_id: label, tag, type, required flag, default value and options (for dropdowns). Use list_list_fields to find the field_id. Read-only.
get_list_field
Returns the state and result of a spam test started with start_email_spam_test. status is waiting (no email received yet: ask the user to send it, then call again), analyzing, completed or expired. When completed: score from 0 to 10, rating (excellent, good, needs_work, at_risk), summary, partial (true when authentication or the filter verdict could not be evaluated), the received email (from, subject, sending IP, size), sections with each check (authentication, blocklists, reverse DNS, headers, content), to_do with the fixes in order of impact and the spam filter rules that fired. Only the analysis is stored, never the message text; details are deleted after 24 hours. The score describes this one message, it is not a promise of inbox placement. Read-only.
get_email_spam_test_result
Returns the full settings of one mailing list by list_uid: general info, default sender (from name, from email, reply-to), notification and company details. If you only know the list name, find its list_uid with list_lists first. Read-only.
