On LinkedIn it runs in two halves: find the people showing the signal and check them against your ICP, then run personalized LinkedIn and email outreach to them from your own connected accounts after you approve the campaign.** traxy runs your entire LinkedIn GTM end to end, from finding high intent leads from social intent to enriching and researching each one, to running relevant, personalized LinkedIn and email outreach to them on autopilot. Autopilot starts only after you approve: you test the campaign on sample leads and approve the launch, then it sends from your connected accounts, or you approve every message in a review queue. This page defines the term and explains how it works. For the product, see [signal-based outbound with traxy](https://traxy.ai/signal-based-outbound) ; for the outreach half, [LinkedIn outbound with traxy](https://traxy.ai/linkedin-outbound) ; for every setup screen, the [signal-based outbound playbook](https://traxy.ai/blog/signal-based-outbound-playbook) . _traxy wrote this guide and describes its own product. traxy facts come from the traxy docs, linked where they are used and checked November 2026. No other vendor is described here._ ## What is signal-based outbound? **Signal-based outbound is outbound where a recorded action by a person, the signal, decides who you contact, when, and what the first message says. Signal-based LinkedIn outbound takes that signal from what people post, comment on, like and view on LinkedIn, and sends the outreach over LinkedIn and email.** The signal is the reason. A founder comments under a post asking how others hired their first salesperson. A head of marketing likes several posts about LinkedIn ads in one week. A VP of sales at a company that fits your customer profile views your profile. Each one is a public action, tied to a named person, that connects to a problem you solve. Signal-based outbound turns that action into a short, specific message that refers to it, instead of a generic pitch to a list. Three things make it work. If one is missing, it becomes ordinary cold outreach with a better story: - **A signal tied to a named person**, with a source you can open and check. - **A fit check**, so you only contact people who match the customers you sell to. Activity from the wrong people is noise. - **Outreach that uses the signal**: the message, the timing and the channel follow from what the person did. It is a method, not a tool category. You can run it by hand with a spreadsheet and LinkedIn search, but the work grows fast: watching activity, checking fit, finding contact details, researching each person and writing to each one. A tool such as traxy runs those steps for you and keeps the evidence on every lead. ## What counts as a signal on LinkedIn, and which signals come from research on each lead? **On LinkedIn, a signal is something a person did on the platform that connects them to your problem: writing, commenting on or liking a post, viewing your profile, following you, or engaging with a competitor's or creator's post. Hiring, funding, job changes, tool switches and custom situations are signals too, but they come from research on each lead, not from LinkedIn activity.** ### LinkedIn activity signals (social intent) - **Posts, comments and likes about the problem you solve.** traxy finds people who write, comment on or like posts about the topics, pains and triggers in your Signal Brief. - **Engagement with posts you choose.** Track people (competitors, influencers, teammates, investors), single posts by URL and company pages by domain, and traxy qualifies whoever engages. A tracked company page finds the people who engage with its posts, not every employee of that company. - **Your own posts.** Track your own profile, and the people who engage with your posts become leads when they fit. - **Profile views, new followers and new connections.** In traxy, the LinkedIn activity card under Targeting > Signals has a Profile views switch, and the [LinkedIn activity docs](https://docs.traxy.ai/discovery/linkedin-activity) also list new followers and new connections. LinkedIn doesn't show viewers who browse in private mode, so traxy doesn't either. - **Social intent search.** Describe the person and the need in plain English and search 71M+ scanned LinkedIn likes, posts and comments. Each result comes with the post or comment behind it ([social intent search](https://traxy.ai/social-intent-search) ). ### Signals from research on each lead Some of the best reasons to reach out never show up in the LinkedIn feed: a company hiring for a role you support, a funding round, a new executive, a switch away from a tool. In traxy these come from research on each lead inside a campaign. You describe the facts you want, such as open sales roles or a recent round, and the campaign researches each lead for them before any message is prepared. You can also describe a custom signal in plain English, for example companies expanding into a new market and looking for an agency, and traxy looks for it. This is research, not a live event feed. It finds what it can for each lead, and there is no promise that every company is covered or of how soon after an event it shows up. To define and test a signal of your own, read [how to set up a custom buying signal](https://traxy.ai/blog/custom-buying-signals-outbound) . ### How strong is a signal? traxy labels each lead by how strong the evidence is ([signals docs](https://docs.traxy.ai/discovery/signals) ): - **Warm:** a direct signal relevant to your offer. - **Related:** contextual evidence connected to your offer. - **Activity:** observed activity with a weaker connection to your offer. - **ICP match:** fit only, with no other recorded signal. The label is separate from the ICP match score. One tells you how good the evidence is, the other how well the person fits; read both before you write ([ICP match score vs signal strength](https://traxy.ai/blog/icp-match-score-vs-signal-strength) ). A like is weaker evidence than a comment that names your problem, and neither one proves someone will buy. ## How is signal-based outbound different from cold outbound and from plain LinkedIn automation? **Cold outbound starts from a list of people who match a profile, and plain LinkedIn automation is a way to send to whatever list you load. Signal-based outbound changes the list itself: it starts from people who did something relevant, checks their fit, and writes to them about that action.** Question Cold outbound Plain LinkedIn automation Signal-based outbound Who is on the list People who match a filter: title, industry, company size The list you bring People with a recorded signal and an ICP fit Why now No reason on their side; the timing is yours The schedule you set They acted recently What the first message refers to Their role or company, plus a pitch Whatever you put in the template The post, comment, view or researched event What decides results List quality and copy The list you load How relevant the signal is, and fit You don't have to pick one. You can keep a sending tool and change where the list comes from. The guide to [LinkedIn automation vs signal-based outbound](https://traxy.ai/blog/linkedin-automation-vs-signal-based-outbound) covers when plain automation is enough and how the two work together, and the guide to [signal-based selling](https://traxy.ai/blog/signal-based-selling-linkedin-social-selling-evolution-b2b-2026) covers the move from social selling to selling on signals. ## How does signal-based outbound work, step by step? **It runs in seven steps: catch the signal, check fit, enrich, group leads into campaigns, research each lead, prepare a sequence per signal group, then test, approve and send.** The first three steps find high intent leads; the last four are the outreach. 1. **Catch the signal.** Decide which actions count for your offer and watch for them. In traxy that is your Signal Brief (buyer pains, triggers, topics, competitors and keywords), the LinkedIn activity you choose, and the people, posts and company pages you track. Every lead keeps the post, comment, like or repost that put them on your list. 2. **Check fit at 50% or higher.** A signal from the wrong person is noise. traxy scores each person against your lead criteria (roles, seniority, location, company size, industry and more), and only people who meet your required criteria and reach a 50%+ ICP match become qualified leads ([qualification docs](https://docs.traxy.ai/discovery/qualification) ). Filtering for a higher score narrows the list; it doesn't change the threshold. 3. **Enrich.** Find a work email and a phone number for the leads you want to reach by email or call. Auto-Enrich looks up contact data for newly qualified leads; it doesn't backfill old ones. 4. **Group leads into campaigns.** Organize leads by signal, audience or offer. A campaign's audience is a shared lead view that updates as leads change, and you can run many campaigns at once on different signals. Campaigns run in priority order, so one lead never gets two campaigns at once. 5. **Research each lead.** Before any message is prepared, the campaign researches each lead for the facts you ask for: the hiring, funding or job change behind a researched signal, or context about the company. It can filter out people who don't fit and group the rest by signal. A research-only campaign records findings without sending. 6. **Prepare one message variant per signal group.** Leads are grouped by signal, and each group gets its own message variant, personalized with the evidence. Someone who commented on a competitor's post gets a different opener from someone who viewed your profile. LinkedIn and email run in one campaign: a sequence can send a connection request, wait for it to be accepted, then follow up by message or email ([sequences docs](https://docs.traxy.ai/outreach/sequences) ). 7. **Test, approve and send.** Test the campaign on sample leads and check the research and drafts with nothing sent. The launch review shows who joins, who is skipped (held by another campaign or contacted before), the sender, the steps and the delivery mode, and choosing Launch is your approval. Then approve every message in a review queue, or let the approved campaign send on its own. Replies, unsubscribes and hard bounces stop the sequence ([review and launch docs](https://docs.traxy.ai/campaigns/review-and-launch) ). That last step is what outbound on autopilot means in traxy: once you have tested the campaign and approved the launch, it runs on its own from your connected accounts, or you keep approving every message. It never means sending with no approval at all. The guide to [signal-based outbound on autopilot](https://traxy.ai/blog/signal-based-outbound-on-autopilot) covers which parts run on their own and which stay with you. ## How do you set up signal-based outbound in traxy? **Set your Signal Brief or describe a custom signal, create a campaign that names the signals and segments, test it on sample leads, then approve the launch.** Nothing sends until you approve, and you can pause or change a campaign anytime. 1. **Give traxy your website.** It drafts your lead criteria (ICP) and signals and shows a lead preview. Fix anything that's off. 2. **Set the Signal Brief.** Under Targeting > Signals, review the topics, buyer pains, triggers, competitors and keywords, and choose which LinkedIn activity becomes leads. Or describe a custom signal to trax, the traxy agent. 3. **Add sources.** Track the competitors, creators and company pages whose engagers you want, paste a single post URL to get its audience, or search social intent in plain English. 4. **Connect senders.** Under Outbound > Sender accounts, connect the LinkedIn accounts and mailboxes you will send from. Each one has limits, active hours and ramp-up, and a campaign doesn't bypass them ([senders docs](https://docs.traxy.ai/outreach/senders) ). A sequence that uses LinkedIn and email needs one sender name with both channels connected. 5. **Create the campaign.** In Outbound > Campaigns, or by asking trax, pick the shared lead view, describe the offer and the research you need, and name the signals and segments so each group gets its own message variant ([create a campaign docs](https://docs.traxy.ai/campaigns/create) ). 6. **Test on sample leads.** Ask trax to test the plan and read the research and drafts in the campaign panel. Nothing is sent. 7. **Review and launch.** Check who joins and who is skipped, the sender, the steps and the delivery mode, then confirm Launch. You can do all of this by hand in the app, from one chat with trax, or from Claude, ChatGPT, Codex, Cursor or Grok through the [traxy MCP](https://traxy.ai/linkedin-mcp) , where the AI shows what it will do and waits for your yes before anything sends or launches. The [signal-based outbound playbook](https://traxy.ai/blog/signal-based-outbound-playbook) walks each screen with an example, from the Signal Brief to the first opener. ## What should you measure in signal-based outbound? **Measure replies and accepted connection requests by signal group, not only for the campaign as a whole.** The reason to group leads by signal is to learn which signals are worth acting on, so the numbers have to stay split the same way. - **Acceptance rate per signal group** on LinkedIn: connection requests accepted out of those sent. - **Reply rate per signal group**, on LinkedIn and email. - **Meetings per group.** In traxy, connect Google Calendar and the Meetings view lists meetings attributed to traxy leads, where you record the outcome. - **Where leads come from.** Insights shows lead volume, trends and the top profiles or posts bringing in leads, so you can see which tracked sources are worth keeping. - **Lead quality.** Mark leads Good fit or Bad fit with a reason. It doesn't rewrite the score, but it records your judgment for the targeting changes you review. Compare groups that ran over the same period with similar messages. If one signal group gets fewer replies than the rest, change the message for that group first; if it still lags, drop the signal or tighten your lead criteria. Replies from both channels land in one inbox, one conversation per lead, where you can answer or pause that lead's sequence and take over. ## What doesn't signal-based outbound promise? **Signal-based outbound gives you a better reason to reach out and a better list. It doesn't promise that anyone will buy, reply or book a meeting.** - **A signal is not a decision to buy.** A like or a comment shows interest in a topic, and the ICP match score measures fit, not the chance someone buys. Read the evidence before you write, and say only what it supports. - **No signal doesn't mean no interest.** Many buyers never post or comment. Signals add warm leads; they don't cover your whole market. - **Researched signals depend on what can be found.** Hiring, funding and job changes come from research on each lead, with no promise of coverage or timing. - **Private profile viewers stay private.** LinkedIn doesn't show people who view profiles in private mode. - **LinkedIn limits still apply.** Each sender has limits, active hours and ramp-up, and no tool can promise zero risk of LinkedIn restrictions. Delivery can also wait on sender availability and schedule. - **It still needs your judgment.** You choose the signals, the offer and the delivery mode, and you approve the launch. A message that refers to a signal clumsily reads worse than a plain note, so check the drafts in the test. - **One lead, one active campaign.** A lead can be in only one active sequence at a time, so overlapping campaigns skip people another campaign already holds. ## FAQ ### Is signal-based outbound the same as intent-based outbound? Mostly. Both start from evidence that someone cares about a problem now. "Intent-based" often means company-level intent data, such as research topics or website visits, while signal-based LinkedIn outbound starts from named people and their recorded actions. traxy works from the second kind: the post, comment, like or profile view behind each lead, plus events found through research on each lead. ### Is signal-based outbound the same as signal-based selling? Signal-based selling is the wider idea of timing sales actions to signals. Signal-based outbound is the prospecting part, where signals decide who gets the first message. See [from social selling to signal-based selling](https://traxy.ai/blog/signal-based-selling-linkedin-social-selling-evolution-b2b-2026) . ### Do I need to post on LinkedIn myself? No. Your own posts are one source, but you can also find leads among people who engage with competitors', creators' and company pages' posts, from a single post URL, from posts about your topics, and through social intent search. ### Can signal-based outbound run on autopilot? Yes, after you approve it. In traxy you test the campaign on sample leads and approve the launch, then it sends on its own from your connected accounts, or you approve every message in a review queue. Replies, unsubscribes and hard bounces stop the sequence. ### Which channels does it use? In traxy, LinkedIn and email in one campaign, from your own connected sender accounts. You can also send a single LinkedIn message, connection request or email to one lead. See [LinkedIn outbound with traxy](https://traxy.ai/linkedin-outbound) . ### Can I run several signal-based campaigns at once? Yes. Run separate campaigns for separate signals, such as competitor engagers, profile viewers and companies hiring for a role you support. Campaigns run in priority order, so one lead never gets two campaigns at once. ### Can I run it from Claude or ChatGPT? Yes, through the traxy MCP. From chat you can find leads, research them, draft, test and launch campaigns, manage sequences and senders, and answer replies. The AI asks for your yes before anything sends or launches. ### Can the leads go to my other tools? Yes. Routes send leads to a webhook, Clay, Zapier, n8n or Slack, and the REST API reads leads, signals and engagements from your own code. ## Related reading - [Signal-based outbound playbook: from Signal Brief to an approved campaign](https://traxy.ai/blog/signal-based-outbound-playbook) - [LinkedIn automation vs signal-based outbound](https://traxy.ai/blog/linkedin-automation-vs-signal-based-outbound) - [Signal-based outbound on autopilot, after you approve the launch](https://traxy.ai/blog/signal-based-outbound-on-autopilot) - [From social selling to signal-based selling](https://traxy.ai/blog/signal-based-selling-linkedin-social-selling-evolution-b2b-2026) - [ICP match score vs signal strength](https://traxy.ai/blog/icp-match-score-vs-signal-strength) - [Signal-based outbound with traxy](https://traxy.ai/signal-based-outbound) - [LinkedIn outbound with traxy](https://traxy.ai/linkedin-outbound) - [Social intent search](https://traxy.ai/social-intent-search) **Next step:** see how [signal-based outbound](https://traxy.ai/signal-based-outbound) runs in traxy, from the signal to the campaign you approve.
