Mach

Mach prices at $1000 monthly for Starter (50 companies researched a month) and $1000 per seat on Team, so an agency's cost scales with seats and research volume rather than with the number of client campaigns it runs. The strategic stake is review labor: Mach turns plain-language instructions into reviewable action/wait/decision playbook steps, which means the agency's margin depends on how fast a human can approve drafts, not on how many messages get generated. Agencies that build a repeatable review and per-client Brain configuration process convert Mach from a high-setup tool into a retainer line item.

Mach prices on two rungs: Starter at $1000 monthly ($833.33 annual) for a single sending domain with a 28-day warm-up, and Team at $1000 monthly per seat ($833.33 annual) for 2 to 10 seats, each seat carrying 50 companies researched a month. The ladder matters because research volume scales with seats, not with clients. An agency running outbound for four clients on one Starter seat shares 50 researched companies across all four, roughly 12 per client per month, which starves any campaign targeting more than a handful of accounts. Moving to Team at three seats buys 150 researched companies and Microsoft 365 plus meeting notes linked to companies and deals, but the monthly cost triples before a single retainer is signed. Model each client engagement against researched-company headroom first, then decide whether the seat cost sits inside a $4,500 Mach Starter Sales Setup fee or gets billed as a pass-through line on the retainer.

Reply-Signal Decay Curve is the point at which added outreach volume starts reducing pipeline value instead of growing it. Every extra sequence step, mailbox, or AI-sent message raises total sends but lowers the share of prospects who answer, and inbox providers punish the pattern at the domain level. Agencies feel this twice: the client sees falling meeting counts while the retainer stays fixed, and the shared sending infrastructure carries the reputation damage into every other account on the same domain. The curve is not linear. A two-step cadence on a warmed domain can outperform a six-step cadence on a cold one by a wide margin, because the second cadence is competing with its own prior sends for the same inbox attention. Tools such as Amplemarket and Salesloft expose deliverability and cadence analytics that make the inflection visible, while Buzz and Apollo make it easy to add volume past the point of return. The operating rule is to measure reply rate per mailbox, not sends per seat.

Every outbound domain carries a finite tolerance for volume and pattern repetition, and sales automation spends that tolerance faster than it earns it. Treat sender reputation as a budget: each new mailbox, each added sequence step, and each AI agent that fires without review draws down the balance, while replies, low complaint rates, and consistent sending patterns replenish it. Agencies that plan outreach against this budget ramp new client domains over weeks rather than days, cap daily sends per mailbox, and separate cold prospecting domains from the domains used for client delivery and invoicing. The budget model also explains why autonomous senders need guardrails: a single misconfigured sequence across a shared domain can exhaust months of accumulated reputation in an afternoon, and recovery takes longer than the original build. Budget the drawdown before the campaign, not after the bounce rate climbs.

Deploy Mach only for a client who has signed off on reviewed, cited outbound and a $1,000 monthly platform cost, and staff the review step before the first playbook goes live.

Scale outreach by adding warmed, separated sending identities and human review checkpoints before raising volume on any existing inbox.

IF your agency sells to software builders and can absorb $1,000 a month for 50 researched companies (or $833.33 annualized per seat on Team, 2 to 10 seats), THEN Mach's website-to-Brain setup plus cited buyer research and one consolidated inbox across email, LinkedIn, and WhatsApp is a workable per-client outbound engine. IF you need white-label delivery or hands-off sending, DEFER: every playbook step and message draft requires manual review before it goes out, and white-label capability is unverified.

A repeatable agency engagement that takes one client from a bare Mach workspace to a live, reviewed multi-channel outbound playbook across email, LinkedIn, and WhatsApp, with cited research and a single consolidated inbox.
