LinkedIn Outreach & Inbox Management
Send personalized messages, organize your inbox with labels and split views, snooze conversations for follow-up, schedule messages, and smart-archive stale threads. Full inbox management through your AI assistant or API.
17 Tools for Outreach & Messaging
Each tool is available as an MCP tool for AI agents or as a REST API endpoint.
Send Message
Send a message in an existing LinkedIn conversation. Only works for EXISTING conversations. If you haven't messaged this person before, use start_conversation instead. Requires the chat_id from list_conversations. Supports campaign tagging for tracking outbound activity.
send_message
Send Connection Request
Send a LinkedIn connection request to someone. Optionally include a personal message (max 300 characters) to increase acceptance rates. Automatically resolves profile URLs and slugs to provider IDs. Supports campaign tagging for tracking outbound connection activity.
send_invitation
Send InMail
Send an InMail message to someone outside your direct network. InMail lets you reach 2nd and 3rd degree connections without needing a connection first. Requires InMail credits on the sender's LinkedIn account. Supports optional subject lines and campaign tagging.
send_inmail
Start Conversation
Start a new LinkedIn message conversation with one or more people. Use this to send the FIRST message to someone. For follow-up messages in an existing conversation, use send_message with the chat_id. Accepts LinkedIn profile IDs or URLs as recipients. Supports group conversations with multiple attendees. Automatically resolves profile URLs to provider IDs.
start_conversation
Get Messages
Get messages from a specific LinkedIn conversation by chat ID. Returns the full message history with sender names, message text, and timestamps. Supports pagination for long conversations. Use list_conversations first to get the chat_id.
get_messages
List Conversations
List your LinkedIn message conversations with contact names, last message preview, and timestamps. Returns chat_id needed by send_message. If you need to message someone new, skip this and use start_conversation. Supports pagination for navigating through your full inbox.
list_conversations
Label Conversation
Add a custom label to a LinkedIn conversation for organization and split inbox views. Labels like 'Hot Lead', 'Client', or 'Candidate' help you filter and prioritize your inbox. A conversation can have multiple labels. Idempotent - adding the same label twice has no effect.
label_conversation
List Conversation Labels
List all labels in use across your conversations with counts. Returns an array sorted by count descending. Use these labels with list_conversations to filter by label for split inbox views.
list_labels
Snooze Conversation
Snooze a conversation to hide it from your inbox until the specified time. When the reminder fires, the conversation resurfaces at the top of your inbox. If the other person replies before the reminder fires, it auto-cancels so you see the reply immediately. Optionally attach a note to remind yourself why you snoozed it.
snooze_conversation
Schedule Message
Schedule a message to be sent in a conversation at a future time. Works outside of campaigns for loose follow-ups like 'message them in 2 weeks'. The message is auto-sent at the specified time. If they reply before then, the scheduled message is auto-cancelled.
schedule_message
List Reminders
List all pending snooze reminders and scheduled messages. Shows what's snoozed, what messages are queued, and when they fire. Filter by status: pending (default), fired, cancelled, sent, failed, or 'all'.
list_reminders
Smart Archive Conversation
Archive a conversation with smart auto-return. Unlike LinkedIn's native archive, the conversation automatically resurfaces in your inbox when the other person sends a new message. Great for cleaning up your inbox without losing track of conversations.
smart_archive
Bulk Archive Conversations
Archive all stale conversations older than N days (default 30, min 7). Only archives conversations where you sent the last message and got no reply. All archived conversations auto-return when the other person replies. Use dry_run=true to preview without archiving.
bulk_archive
Create Campaign
Create a new campaign for tracking outbound LinkedIn actions. Campaign IDs are user-defined slugs (e.g. 'q1-fintech-outreach'). Once created, tag any send_message, send_invitation, create_post, or other action with the campaign_id to track performance.
create_campaign
List Campaigns
List your campaigns with action counts. Returns active campaigns by default, with an option to include archived ones. Shows campaign name, creation date, and total actions tracked under each campaign.
list_campaigns
Archive Campaign
Archive a campaign. Archived campaigns stop accepting new actions but all historical data is preserved for reporting. Use this to close out completed campaigns and keep your active campaign list clean.
archive_campaign
Get Campaign Stats
Get detailed campaign performance stats: action counts by tool type, daily breakdown of activity, and per-account breakdown for multi-account setups. Supports a configurable lookback window for time-bounded reporting.
get_campaign_stats
Use Cases
Here's how teams use Crispy's outreach & messaging tools in their day-to-day workflows.
Personalized outreach at scale
Have your AI agent research each prospect and craft a unique message based on their profile, recent posts, and shared connections.
Example prompt
“Research this prospect's profile, then send them a connection request mentioning their recent post about AI”
Multi-step drip campaigns
Build automated sequences: connection request, follow-up message after acceptance, then a meeting request - all managed by your AI agent.
Example prompt
“Create a 3-step outreach campaign targeting CTOs at fintech startups in London”
Manage inbox at scale
Label conversations as 'Hot Lead' or 'Client', snooze threads for follow-up, schedule messages for later, and bulk-archive stale conversations. Split inbox views let you focus on what matters.
Example prompt
“Check my inbox, label any VP+ conversations as 'Hot Lead', snooze the rest for next week, and archive anything older than 30 days”
InMail outreach to non-connections
Reach prospects outside your network with InMail. Crispy handles the full lifecycle from send to tracking opens.
Example prompt
“Send an InMail to this Sales Navigator lead introducing our product”
Sync conversations to your CRM
Connect Crispy alongside HubSpot, Salesforce, or Pipedrive MCP servers. Your AI agent automatically logs new LinkedIn contacts and conversation summaries to your CRM - zero middleware required.
Example prompt
“Sync all my unread LinkedIn conversations to Salesforce and create contacts for anyone new”

Frequently Asked Questions
Will my LinkedIn account get restricted?
Crispy respects LinkedIn's rate limits and includes a built-in Safety Calculator to help you stay within safe thresholds. We recommend gradual ramp-up for new accounts.
Can I schedule messages to send later?
Yes. Use schedule_message to send a message at any future time. It works outside of campaigns for loose follow-ups. If the person replies before the scheduled time, the message auto-cancels.
How many messages can I send per day?
LinkedIn has its own daily limits (typically 100-150 connection requests, 50-100 messages). Crispy enforces these limits to protect your account.
Does Crispy store my message content?
Messages are sent directly through your LinkedIn session. In managed mode, contacts and activity metadata are stored for Unibox. In BYOS or stateless mode, you control what's retained.
Can I use templates with personalization variables?
Your AI agent handles personalization natively - it can pull profile data and weave it into messages dynamically. No rigid template system needed.
Can I sync LinkedIn conversations to my CRM?
Yes. Connect Crispy and your CRM's MCP server (HubSpot, Salesforce, Pipedrive) to the same AI agent. Say 'sync my LinkedIn conversations to my CRM' and the agent handles contact creation, conversation logging, and deal updates. No custom code, no Zapier - just two MCP servers working together.
