LinkedIn prospect post signal outreach
Last updated 15 October 2026
When you run a LinkedIn prospect post signal outreach campaign, HeyLead helps you connect with people who just published new content.
What the prospect post signal is
A prospect post signal means a person in your campaign published a new LinkedIn post. It comes from a person's own activity on LinkedIn. The signal is attached to one person.
HeyLead is an AI agent for LinkedIn outreach: it finds the right people, writes to them in the voice of your own LinkedIn posts, follows up, and handles replies. It runs from Claude Code, Cursor, any MCP client or a web dashboard.
What to write when a prospect posts
You need a specific approach for this outreach. Open with what they did in a sentence about it. You can mention the post, the move, or the comment.
Then ask one question they can answer in writing. You must include no pitch in the first message.
How HeyLead detects the prospect post signal
HeyLead re-reads the profiles and posts of people in your campaigns. It searches LinkedIn for your keywords. HeyLead watches 40+ signal types. These are scored, matched to your ICP and expiring.
The prospect post signal has a weight of 0.35 in HeyLead's score. Scores run from -0.30 to 0.90. A negative score lowers priority. When several signals name one person, this signal has a priority rank of 30. A lower rank wins. The signal expires after 14 days.
How to use HeyLead for your campaign
You type a one-sentence brief in Claude, Cursor, ChatGPT or the HeyLead dashboard. HeyLead drafts the campaign. You review it and press Launch. Nothing is sent before.
Before an invitation, HeyLead warms up. It does a profile view, a follow, and a comment on a recent post. A strong signal starts outreach and the opener says why now. The prospect post signal raises priority but does not write the invite note.
An invitation includes a note, an opening message, up to 2 follow-ups on Free and 5 on Pro, InMail and email fallback.
Managing replies and campaign goals
Replies are read, classified and answered from the campaign's facts. Anything ambiguous is held for you. A not now reply gets a check-in in 30 days.
Opening messages, follow-ups and answers to replies wait for your approval until you switch to autopilot. Invitations, not-now check-ins and meeting nudges are not held.
You can set six campaign goals. These are sell a product or service, find a job, hire people, find partners or investors, find a vendor, and research interviews. Hire people, find partners or investors and research interviews work with a custom brief.
Setup and integrations
HeyLead reads your own LinkedIn posts to learn your voice. It never posts unless you ask for a post. It runs from the cloud with your laptop closed. The client's source is on GitHub under MIT. The hosted backend is not.
Free costs $0 for one connected account with 2 follow-ups. Pro costs $29 a month per connected account. HeyLead syncs with HubSpot. It books into Google Calendar.
It works in Claude Code, Cursor, Claude Desktop and claude.ai, any MCP client and a web dashboard. It works in ChatGPT as a custom MCP app. This was tested on ChatGPT Pro. Custom apps depend on your ChatGPT plan and settings.

It backs off when LinkedIn pushes back and resumes on its own. You can pause any campaign at any time.
