list_subscribers
Retrieves a paginated list of subscribers. Can filter by subscriber status (active, unsubscribed, unconfirmed, bounced, junk), include group memberships, or request the total subscriber count with limit 0. Use cursor-based pagination to iterate through large lists.
get_campaign_report
Retrieves campaign details and subscriber activity reports for a sent campaign. Returns engagement data including opens, clicks, unsubscribes, and bounces.
delete_campaign
Permanently deletes a campaign from the account. This action cannot be undone.
list_groups
Retrieves all subscriber groups in the account. Can filter by group name and includes statistics like active subscriber count, open rate, and click rate for each group.
manage_custom_field
Creates, updates, lists, or deletes custom subscriber fields. Custom fields store additional data on subscribers (e.g., name, company, phone). Supported field types are **text**, **number**, and **date**.
manage_group_subscribers
Assigns or removes a subscriber from a group, or lists all subscribers in a group. Use this to manage group membership for individual subscribers.
list_automations
Retrieves automations in the account, optionally filtered by enabled status, name, or group. Can also fetch a specific automation's details or subscriber activity within an automation.
list_campaigns
Retrieves a list of campaigns. Can filter by status (draft, ready, sent) and type (regular, A/B, resend). Returns campaign details including name, type, status, and send statistics.
list_forms
Retrieves signup forms filtered by type (popup, embedded, promotion). Can also fetch subscribers who signed up through a specific form.
get_subscriber
Fetches detailed information about a single subscriber by their ID or email address. Returns subscriber profile data including custom fields and group memberships.

get_subscriber_activity
Retrieves activity logs for a specific subscriber, including email opens, link clicks, group changes, bounces, and more. Useful for tracking subscriber engagement.
create_or_update_subscriber
Creates a new subscriber or updates an existing one by email address. This is a non-destructive upsert operation — omitting fields or groups will not remove them from an existing subscriber. Can assign subscribers to groups and set custom field values. **Note:** If a subscriber's status is unsubscribed, bounced, or junk, you cannot reactivate them via the API.
list_segments
Retrieves all segments in the account. Segments are rule-based subscriber groupings created in the MailerLite UI. Can optionally fetch subscribers belonging to a specific segment.

manage_webhook
Lists, gets, creates, updates, or deletes MailerLite webhooks for subscriber and campaign events. For campaign.open, campaign.click, and subscriber.deleted events, MailerLite requires batchable to be true.
