How to use the LinkedIn frequent reactions signal
Last updated 28 October 2026
When you want to use the LinkedIn frequent reactions signal for outreach, HeyLead finds the right people and drafts the campaign.
What the frequent reactions signal is
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.
The reaction pattern signal means a person reacted to posts in a week. This shows they are active on LinkedIn. The source is a person's own activity on LinkedIn. It is attached to one person.
HeyLead watches 40+ signal types, scored, matched to your ICP and expiring. The reaction pattern signal has a weight of 0.25 in HeyLead. Scores run from -0.30 to 0.90, and a negative score lowers priority. This signal expires after 7 days.
Why the frequent reactions signal matters
A strong signal starts outreach and the opener says why now. This signal raises priority for the person in your campaign. It does not write the invite note.
HeyLead re-reads the profiles and posts of people in your campaigns and searches LinkedIn for your keywords to find this signal. Before an invitation, HeyLead warms up: a profile view, a follow, a comment on a recent post.
You can use this signal to sell a product or service, find a job, hire people, find partners or investors, find a vendor, or research interviews. Hire people, find partners or investors and research interviews work with a custom brief.
What to write for this signal
When you write to a person who triggered this signal, open with what they did. Mention the post, the move, or the comment in a sentence about it.
Then ask one question they can answer in writing. You must include no pitch in the first message.
An invitation with a note, an opening message, up to 2 follow-ups on Free and 5 on Pro, InMail and email fallback are part of the sequence. 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.
The brief to type into HeyLead
You type a one-sentence brief in Claude, Cursor, ChatGPT or the HeyLead dashboard. One sentence creates a draft campaign.
HeyLead drafts the campaign. You review it and press Launch. Nothing is sent before you press Launch.
It works in Claude Code, Cursor, Claude Desktop and claude.ai, any MCP client and a web dashboard. It also works in ChatGPT as a custom MCP app. This is tested on ChatGPT Pro. Custom apps depend on your ChatGPT plan and settings. 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 reads your own LinkedIn posts to learn your voice and never posts unless you ask for a post. It runs from the cloud with your laptop closed.
HubSpot is the CRM it syncs with. Google Calendar is the calendar it books into.
