Capabilities
Tools 88
add_contacts
Add Contacts to a List - Add multiple contacts to an existing list. Contacts must come from an evidenced import or consent source that the account holder already has (e.g. their own opt-in list, CRM export, or inbound leads) — do not assemble addresses from model knowledge or web scraping. All contact field names use snake_case (e.g. first_name, last_name, email, phone, company_name, job_title, lead_score). Custom snake_case fields are added to the list's columns. The `starred` boolean is a contact setting and is not added as a list column. Contact archiving is handled by archive_contact.
Discovered add_to_blocklist
Add to Blocklist - Add emails and/or domains to the blocklist
Discovered add_user
Add a User - Invite a new user to your account
Discovered archive_contact
Archive or Unarchive a Contact - Archive leads/contacts to remove from active campaigns

Discovered archive_sequence

Discovered check_blocklist
Check Blocklist - Check whether an email is blocked
Discovered clone_sequence
Clone a Sequence - Create a copy of an existing sequence
Discovered create_folder
Create a Folder - Create a new folder for organizing items. The type field is supported only for email-sender folders; general folders for lists, templates, and sequences do not use it.
Discovered create_inbox_placement_test
Create Inbox Placement Test - Test email deliverability across providers
Discovered create_list
Create a List - Create a new contact list. Contacts added to lists must originate from an evidenced import or consent source that the account holder already has (e.g. their own opt-in list, CRM export, or inbound leads) — not addresses assembled by the model. The response includes a `fields` array — the list's columns in snake_case (e.g. first_name, email).
Discovered create_sequence
Create a Sequence - Create a new email sequence/campaign. Recipients must be the account holder's own contactable audience (e.g. their own opt-in or otherwise consented contacts) — never addresses assembled by the model — and suppression/blocklist is always enforced. Sequences are created paused by default; launching (resuming) sends emails to recipients and must only happen after explicit user confirmation.
Discovered create_template
Create a Template - Create a new email template. Attachments are not supported on this connector — to send files, attach them via the SalesBlink web app.
Discovered create_workspace
Create Workspace - Create a new workspace (owner only)
Discovered delete_api_key
Delete API Key - Revoke an API key. Requires explicit user confirmation, since revoking a key immediately breaks any live integration using it.
Discovered delete_blocklist_entry
Delete Blocklist Entry by ID - Remove a single blocklist entry by its ID. Requires explicit user confirmation, since the removed address becomes eligible for outreach again.
Discovered delete_inbox_placement_test
Delete Inbox Placement Test - Remove a deliverability test. Requires explicit user confirmation, since deletion cannot be undone.

Get Add Card Login Link - Generate a magic login link to add a payment card
Discovered get_all_folders
Get All Folders - Retrieve all folders. The type filter supports 'all', 'general', and 'email-sender'. General folders (created without a type) hold lists, templates, and sequences; email-sender folders hold email senders only.
Discovered get_all_lists
Get All Lists - Retrieve all contact lists with optional filtering. Note: boolean filters (starred/archived) are unreliable. Supported filters: folder, search, sortBy, sortType, integration. Each list includes a `fields` array — the list's columns in snake_case (e.g. first_name, email, lead_score).
Discovered get_all_senders
Get All Email Senders - Retrieve all email sender accounts (flat list, not grouped by folder)
Discovered get_all_sequences

Discovered get_all_users

Discovered get_api_keys
Get API Keys - Retrieve all API keys for the account. For security, returned keys are masked (only the first and last 3 characters are shown, e.g. 'abc...xyz') — full key values are never exposed by this tool. To view or copy a full key, the account holder must use the API-key management page in the SalesBlink app (see get_api_key_page_link/get_api_key_refresh_link for a login link).
Discovered get_blocklist
