BigMailer

Bigmailer Delete Contact

Permanently delete a contact from a BigMailer brand. This removes the contact and all associated data. This action cannot be undone.

Bigmailer Delete Field

Permanently delete a custom field from a BigMailer brand. This removes the field definition and all associated contact values. This action cannot be undone.

Bigmailer Delete List

Permanently delete a mailing list from a BigMailer brand. The contacts in the list are NOT deleted — only the list grouping is removed. This action cannot be undone.

Bigmailer Fetch Message Types

List all message types defined for a brand. Message types represent categories of communication (e.g. marketing, product updates, newsletters) that contacts can independently subscribe to or unsubscribe from. Returns: id, name for each message type. Use this to understand opt-out granularity and to correlate with contact unsubscribe_ids.

Bigmailer Fetch Segments

List all audience segments for a brand, or fetch a single segment by ID. Segments are dynamic audience slices defined by conditions with an operator (all/any). Pass segment_id to get one segment's full details including conditions; omit to list all. Returns: id, name, operator, conditions array, size. Use this to understand targeting rules before sending campaigns or analyzing audience overlap.

Bigmailer List Brands

List all brands in your BigMailer account, or fetch a single brand by ID. Brands are the top-level organizational unit — you need a brand_id from this tool before querying any brand-scoped resources (campaigns, contacts, lists, etc.). Pass brand_id to get one brand's full details; omit to list all. Returns: id, name, url, connection_id, from_name, from_email, bounce_danger_percent, max_soft_bounces, contact_limit, created. List mode includes cursor for pagination.

Bigmailer List Bulk Campaigns

List all bulk (mass-send) email campaigns for a brand, or fetch a single campaign by ID. Use this to review campaign status, scheduling, and delivery metrics. Pass campaign_id to get one campaign's full details; omit to list all. Returns: id, name, status (draft/pending/in progress/complete/error/paused/archived/active), subject, from_name, from_email, send schedule, and delivery statistics. List mode includes cursor for pagination.

Bigmailer List Contacts

List all contacts for a brand, or fetch a single contact by ID or email address. Pass contact_id (UUID or email) to get one contact's full details; omit to list all. Returns: id, email, field_values (custom data), list_ids (list memberships), unsubscribe_all, unsubscribe_ids (message type opt-outs), num_soft_bounces, num_hard_bounces, num_complaints, created. Use this for contact lookups, audience inspection, and bounce/complaint analysis.

Bigmailer List Fields

List all custom fields for a brand, or fetch a single field by ID. Custom fields define the data attributes available on contacts (e.g. FIRST NAME, BIRTHDAY, EMPLOYEE ID). Pass field_id to get one field's details; omit to list all. Returns: id, name, type (string/integer/date). Use this to understand what personalization and segmentation data is available before querying contacts.

Bigmailer List Lists

List all mailing lists for a brand, or fetch a single list by ID. Mailing lists are named groupings of contacts used to target campaign sends. Pass list_id to get one list's details; omit to list all. Returns: id, name, subscriber count, created. Use this to understand audience segmentation by list before sending campaigns or analyzing contacts.

Bigmailer List Suppression Lists

List all suppression lists for a brand, or fetch a single suppression list by ID. Suppression lists track contacts excluded from sends due to bounces, complaints, or manual opt-outs. Pass suppression_list_id to get one list's details; omit to list all. Returns: id, name, suppression reasons, contact count. Use this to audit deliverability compliance and manage do-not-email exclusions.

Bigmailer List Transactional Campaigns

List all transactional email campaigns for a brand, or fetch a single campaign by ID. Transactional campaigns are event-triggered emails (password resets, order confirmations, etc.) — separate from bulk campaigns. Pass campaign_id to get one campaign's full details; omit to list all. Returns: id, name, subject, triggers, performance data, API settings. List mode includes cursor for pagination.

Bigmailer List Users

List all users with access to your BigMailer account. Users are account-scoped (not brand-scoped) and have roles: admin, account_manager, brand_manager, campaign_manager, or template_manager. Returns: id, email, name, role, allowed_brands (for role-restricted users). Use this to audit team access, review permissions, or identify who manages which brands.

Bigmailer Send Transactional

Send a transactional email through a BigMailer transactional campaign. Transactional emails are event-triggered messages like password resets, order confirmations, or welcome emails. The recipient contact is created if it doesn't exist. Supports field_values (persisted to the contact) and variables (temporary, for this send only). Returns the contact_id of the recipient.

Bigmailer Upsert Contact

Create a new contact or update an existing one in a BigMailer brand. Matches on email address — if a contact with the given email exists, their fields are updated; otherwise a new contact is created. Optionally set custom field values, list memberships, and unsubscribe preferences. Returns the created/updated contact ID.

Bigmailer Upsert Field

Create a new custom field or update an existing one in a BigMailer brand. Pass field_id to update an existing field, or omit to create a new one. Creating requires name and type (text/integer/date). Returns the created/updated field ID.

Bigmailer Upsert List

Create a new mailing list or update an existing one in a BigMailer brand. Pass list_id to update an existing list's name, or omit to create a new list. Returns the created/updated list ID.
