Signal-based outbound runs on two scores and a quarterly cut

Your SDR manager opens the intent dashboard at 8 a.m. with one question: which accounts does the team call first? The dashboard ranks activity, and the team needs a decision. With a signal program, you make that decision each morning, before the first dial, and write the reasoning down.

In 6sense’s 2025 Buyer Experience Report, built on nearly 4,000 survey responses, 94% of buying groups ranked their shortlist before they spoke to a seller, and buyers initiated 79% of engagements. Outbound that waits for a raised hand shows up after the list is written.

What counts as a signal

A signal is an observable event, tied to a named account or person, that changes the odds of a purchase inside a window you can name. A job post for a head of RevOps qualifies. A whitepaper download from a graduate student fails the test. Sort signals by who owns the data: the closer the source sits to you, the more accurate the signal and the fewer competitors who see it.

• First-party, from systems you own: product usage (a trial reaches the feature your best customers adopt first), website behavior (pricing and comparison pages from a known account) and inbound (demo requests, chat, replies, event sign-ups). Highest intent, lowest volume.
• Second-party, from someone else’s platform: community activity (questions in your Slack group, stars on your GitHub repo), partner overlap (Crossbeam maps which of your targets already buy from a partner) and review sites (G2 Buyer Intent flags accounts viewing your category, competitor comparisons, pricing pages and reviews).
• Third-party, observed in public or bought: hiring for roles your product supports, funding rounds, technology installs (BuiltWith tracks more than 127,700 internet technologies) and topic intent (Bombora compares an account’s last three weeks of activity on a topic against a 12-week baseline).
• Relationship signals, sitting in your CRM: a past champion starts a new job, a closed-lost account reaches its agreed revisit date, a churned customer hires a new leader, a customer gets acquired.

Get on the list before it is written

Gartner says nearly all B2B purchases take place amid organizational change. New leaders, funding rounds, reorgs and hiring plans are the visible versions, and they can surface before a buying journey starts, the window where outbound can still shape the Day One shortlist. Research signals, such as an intent surge built on three weeks of reading, fire once the journey is underway.

Run the arithmetic on 6sense’s averages: buyers evaluate 5.1 vendors and fill 3.6 of those seats on Day One, so about one and a half seats open after the journey starts. Since buyers pick from the Day One list 95% of the time, those late seats split about one win in 20. Use change signals to get on the list early, and work research signals fast and cheap, because they compete for the late seats.

Score fit and heat separately

Fit measures whether you want the account at all: industry, size, stack and what your best customers had in common when they bought. Heat measures whether this week is the moment: how strong the signals are and how fresh. Blend the two into one number and a hot account outside your ICP outranks a quiet perfect-fit account, which is how SDRs end up booking meetings that AEs disqualify on the first call.

Give heat a half-life. A demo request is worth a call today and close to nothing in a month, while a funding round can stay live for a quarter. Stack signals before you spend a human: a lone intent spike earns automation, and intent plus a new VP in your buyer’s function earns an SDR.

Route on ownership before score. A signal on an account with an open opportunity goes to the AE. A signal on a customer goes to the account owner, because a pricing-page visit from a customer can mean expansion or a renewal fight. The rest flows to SDR or agent queues by tier, each with a written, measured response time.

Plays and timing by signal

• Hand-raisers and product thresholds: the same business day. A demo request, a chat, a pricing-page visit from a known contact or a trial crossing your conversion threshold goes to a human. 6sense reads that first contact as preference: the vendor buyers contact first wins about 80% of the time. Slow follow-up gives that lead away.
• Change signals (a new executive, a funding round, a reorg, a hiring push in your buyer’s function): within two weeks of the news. Write about the plan they now own and the problem it creates, and save the product for the second touch. A new VP of Sales who posted six SDR roles last week has a ramp problem you can name in one sentence.
• Research signals (an intent surge, G2 category research, a competitor comparison, a de-anonymized website visit): within the week, to more than one person at the account. Assume a shortlist exists and give the buying group a reason to add one more vendor. Write to the problem the page solves and leave the visit out of the email.
• Relationship and partner signals (a past champion at a new company, partner overlap): your warmest outbound. Give the champion a few weeks to see what they inherited, then ask about it. On partner overlap, ask the partner’s account owner for context or an intro first.

Who works which signal

Split the work by tier. AI agents and automation take the volume: single third-party signals and first touches on lower-tier accounts. They also write the research briefs your reps read before a call. HubSpot says its Prospecting Agent monitors more than 40 buying signals and drafts outreach to the buying group it assembles, and 6sense sells AI email agents that send and reply based on its signal data.

SDRs take stacked signals at high-fit accounts and the hand-raisers that need judgment. Somebody also has to own the plumbing: wiring sources into the CRM, deduplicating accounts, maintaining the scores and switching off signals that stop converting. That job now carries a title, GTM engineer, and Clay markets its platform straight at the people who hold it. Without that owner, the signal list grows until it turns into the intent dashboard the SDR manager stopped opening.

The stack, by category

• Account identification: 6sense and Demandbase for de-anonymization and in-market scoring, RB2B for person-level website visitors (U.S. traffic only).
• Intent and people: Bombora for topic intent, G2 Buyer Intent for review-site research, UserGems for job changes and M&A, Common Room (owned by Zoom since July) for community and product activity.
• Ecosystem and technographics: Crossbeam for partner account overlap, BuiltWith for technology installs and competitor adoption.
• Orchestration and execution: Clay to enrich and route, and Salesloft, Outreach, HubSpot or the agents above to run the touches.

Deliverability guardrails

The fastest way to kill a signal program is to burn the domain it sends from. Since February 2024, Gmail has required anyone sending to personal Gmail accounts to authenticate with SPF or DKIM, publish valid forward and reverse DNS, send over TLS and keep reported spam below 0.3%, with 0.1% as Google’s stated target. Senders that reach roughly 5,000 messages a day must also set up both SPF and DKIM, publish DMARC, align the From domain, support one-click unsubscribe and honor unsubscribes within 48 hours. Yahoo enforces a near-identical standard, down to the two-day unsubscribe window.

Microsoft followed on May 5, 2025: domains sending more than 5,000 emails a day to Outlook.com accounts must pass SPF, DKIM and DMARC (at least p=none, aligned with SPF or DKIM). Failing mail goes to junk, and if the problem stays unresolved, Microsoft may reject it with error 550 5.7.515. Gmail ramped up its own enforcement in November 2025, and mail that misses its requirements now risks temporary and permanent rejections. None of the three providers’ requirement pages lists a new rule dated 2026.

Two details catch outbound teams. Gmail counts all mail to personal Gmail accounts from one primary domain toward the 5,000 threshold, subdomains included, so marketing’s newsletter on a subdomain and your SDRs on the root domain share one count. And once Gmail classifies a domain as a bulk sender, the label is permanent.

Google’s rules skip Workspace recipients. Build each sending domain to the bulk standard anyway, because a permanent label can arrive with a newsletter your team did not send.

Measure each signal like a channel

Report two numbers by signal type each month. Meetings per signal is meetings booked divided by signals worked. Signal-to-opportunity rate is qualified opportunities created within 90 days divided by signals worked. Add time to first touch, because a hand-raiser worked in an hour and one worked on day three are different assets.

Then prune. Hold out a cold control group and compare: a signal type that cannot beat cold outbound on signal-to-opportunity rate over a quarter loses its human coverage and drops to automation or off the list. You will add signals faster than you retire them, so give the cut to the leader who owns the number and have the GTM engineer switch off what goes.

Decide this quarter which signals your SDRs stop working. Coverage you cannot staff is a dashboard, and you already own one of those.
