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_list

Archive or Unarchive a List - Archive lists to remove them from active views

Discovered
archive_sequence

Archive or Unarchive a Sequence - Archive sequences to pause and hide them

Discovered
archive_template

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 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

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)

get_api_keys

Get API Keys - Retrieve all API keys for the account.
