Nothing serious here today

Today is the operative word: we check SalesBlink Cold Email every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.

Available tools 88

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

all

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.

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).

get_all_senders

Get All Email Senders - Retrieve all email sender accounts (flat list, not grouped by folder)

get_all_sequences

Get All Sequences - Retrieve all sequences with optional filtering. Note: boolean filters (starred/archived) and owned_by are unreliable. Supported filters: search, status, folder, sortBy, sortType, sendAll.

get_all_templates

Get All Templates - Retrieve all email templates with optional filtering. Note: boolean filters (starred/archived) are unreliable. Supported filters: folder, type, taskType, search, sortBy, sortType.

get_all_users

Get All Users - Retrieve all users in the account. Note: pagination and filtering parameters are accepted for compatibility but currently have no effect — the endpoint returns every user in the account with no pagination or filtering.

get_all_workspaces

Get All Workspaces - Retrieve all accessible workspaces (owner only)

sequence

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.

get_sequence

Get a Specific Sequence - Retrieve details of a specific sequence

get_sequence_leads

Get Sequence Leads - List leads in a sequence. Supported filters: status. not_contacted/contacted are evaluated on the lead's first-outreach task (first email not yet sent / sent); opened/clicked/replied/bounced/unsubscribed match engagement recorded on any step of the sequence.

get_sequence_stats

Get Sequence Stats - Retrieve statistics for a specific sequence

update_sequence

Update Sequence Properties and State. Archiving is handled by archive_sequence. Recipients must be the account holder's own contactable audience and suppression/blocklist is always enforced. Changing launch settings to start sending emails must only happen after explicit user confirmation.

update_sequence_status

Update Sequence Status - Start, pause, stop, or archive a sequence. Setting status to ACTIVE starts sending emails to recipients and requires explicit user confirmation from the account holder.

sender

fetch_sender_messages

Fetch Sender Messages - Retrieve sent emails and received replies for a sender (max 50 messages, use skip for pagination)

get_sender_connect_link

Get Sender Connect Link - Returns a magic login link to the email-sender connection page where the user can connect a Gmail, Outlook, or SMTP/IMAP sender.

get_sender_health

Get Sender Health - Get sender health and reputation score

get_sender_warmup_stats

Get Sender Warmup Stats - Date-wise warmup stats (sent, sent_replies, received, received_replies, spam_to_inbox) plus per-ESP breakdown (esp_info: google/outlook/others with totalCount and spam_to_inbox)

update_sender

Update Sender - Update email sender settings (warmup, inbox, signature, tracking domain, etc.)

analytics

get_analytics_daily

Get Daily Analytics - Day-wise overall stats

get_analytics_lead_stats

Get Lead-level Analytics - Lead-level stats

get_analytics_mailbox_stats

Get Mailbox Analytics - Overall mailbox stats

get_analytics_overall

Get Overall Analytics - Overall stats across all sequences

api

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.

get_api_key_page_link

Get API Key Page Link - Returns a magic login link to the API keys page where the user can create a new API key.

get_api_key_refresh_link

Get API Key Refresh Link - Returns a magic login link to the API keys page where the user can refresh an existing API key.

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).

archive

archive_contact

Archive or Unarchive a Contact - Archive leads/contacts to remove from active campaigns

archive_list

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

archive_sequence

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

Add to Blocklist - Add emails and/or domains to the blocklist

check_blocklist

Check Blocklist - Check whether an email is blocked

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.

get_blocklist

Get Blocklist - List blocked emails and domains

inbox

create_inbox_placement_test

delete_inbox_placement_test

Delete Inbox Placement Test - Remove a deliverability test. Requires explicit user confirmation, since deletion cannot be undone.

add_contacts

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.

create

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).

SalesBlink Cold Email — questions

Answers built from our own checks of this server.

What can SalesBlink Cold Email do?

It exposes 88 tools, read directly from the server on our last check. Among them: add_contacts, add_to_blocklist, add_user, archive_contact, archive_list, archive_sequence and 82 more. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

What is SalesBlink Cold Email mostly used for?

Its tools cluster around all, sequence and sender. That is what this server is built to work with — the grouping comes from the actual tool names, not from a category we assigned.

Is SalesBlink Cold Email working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 82 of 82 checks got a reply (100.0%), average response time 375 ms. The bar chart above shows every period we have measured.

How do I connect SalesBlink Cold Email?

Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does SalesBlink Cold Email need an API key?

No. SalesBlink Cold Email completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 88 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is SalesBlink Cold Email?

It answers our handshake in 375 ms on average, which is faster than 39% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.

Is SalesBlink Cold Email open source?

The code is open source: it is published under the MIT licence, written in JavaScript and 20 stars on GitHub. The licence covers the code in the repository, not the hosted service at mcp.salesblink.io, which runs on its operator's own terms.
