TAM Outbound Campaign
Large-scale campaigns targeting the total addressable market. A fit for firms ready to scale but limited by outbound capacity. Fully taps into your market potential.
You cover 10% of TAM
Your Total Addressable Market has just never been fully mapped, segmented, or contacted.
Invisible Market
Without a counted TAM, you cannot measure penetration. You have no idea if you've reached 5% of your market or 50%. That gap changes every decision about channels, headcount, and investors.
Wrong Accounts
Without a structured TAM, campaigns run on recognisable names and overcontacted segments. The qualified accounts stay invisible while the budget goes to the wrong companies.
Bad Segmentation
One campaign for every segment produces average reply rates across the board. The CTO gets the same message as the HR Manager and neither converts.
We map market.
You get leads
From TAM architecture to lead handoff. We build the database, write and test sequences per segment, and monitor both channels daily. You receive interesting leads with full context.
Architect your TAM
Clear benchmarks against a fully mapped market. You measure penetration, coverage, and pipeline from day one.
Market Clarity
After 3-9 campaigns you know which message lands with which role in which vertical. Every next budget decision has real data behind it.
01
Market Signal
Two channels across your full TAM generate both leads and intelligence. You know which segment responds, on which channel, and at what rate.
02
80% TAM Coverage
Min. 1,000 accounts structured, enriched, and reached across both channels. 80% of your TAM contacted means no qualified buyer stays invisible.
03
Lasting Asset
The TAM database built during your campaign becomes the backbone for every next campaign, ABM audience, and investor conversation about your market.

FAQs
Answers to the questions we hear most from B2B sales and growth leaders.
What is a TAM-Based Outbound Campaign and how does it work?
TAM-Based Outbound Campaigns is a managed outbound service that starts with mapping your total addressable market - every qualified company that fits your ICP - and then running coordinated cold email and LinkedIn campaigns across the entire database. Vanderbuild builds the TAM, enriches it in Clay, segments it by role and ICP angle, writes copy per segment, and runs daily monitoring across both channels. You receive interested leads with full context. We don't hand you a list; we work through it for you.
How long does it take to build the TAM and see first results?
TAM architecture and the offer workshop take approximately 2-3 weeks depending on market complexity and the number of geographies. First outreach goes out in week 3. Reply signals typically appear within 4-5 weeks. Full campaign metrics across all segments are visible after 60-90 days, with enough data to optimise by segment and channel.
What do I need before we start?
You need a working ICP hypothesis - a description of the company type, size, industry, and geography you're targeting. You don't need a prospect list; we build the TAM database in Clay. You'll need to approve the segmentation logic and enrichment criteria in the workshop before research begins. No tech stack is required on your end.
What's the market size I need for this to make sense?
We set a floor of min. 1,000 qualified accounts in your TAM before activating a campaign. Below that threshold, TAM-based coverage doesn't unlock the scale advantages the service is built for. If your addressable market is smaller, a targeted LinkedIn or cold email campaign may be a better fit - we'll tell you this on the call.
Which channels and tools do you use for TAM outreach?
Cold email runs via Instantly with warm-up protocols on dedicated sending infrastructure. LinkedIn outreach runs via HeyReach within platform limits, from your team's profiles. TAM research and enrichment runs entirely in Clay - firmographics, tech signals, and contact-level data per buying role. All copy is segmented by ICP angle and role, not sent as a single sequence across the full database.
