The channel got repriced underneath you: several times the touches for materially fewer replies. Nobody on your team changed; the price of a reply did. Re-architect the outbound, do not re-staff it.
What repricing looks like
You can see it in your own dashboards: reply rates that held for years have thinned, and the volume it takes to book one meeting keeps climbing. The mailbox providers moved first. Google and Yahoo's bulk-sender rules now enforce SPF, DKIM, and DMARC; spam-rate thresholds are measured in fractions of a per cent; and a burned domain takes months to come back, if it comes back at all. Every inbox between you and the buyer now runs better filters than most sequences run copy.
The wrong fix
The instinctive fix makes it worse. More seats, more domains, more touches a month: that buys volume at falling yield. It also spends the one thing the channel now prices hardest: the buyer's willingness to open anything from you at all.
The frame we use is the attention supply chain: the path scarce senior attention travels to become revenue, be it the founder's own or the attention you pay for by the seat. A fixed sales org buys that attention at fixed cost whether it converts or not; we buy it as measured flow, priced per unit of attention that converts. Outbound sits at the top of that chain, where your attention is traded for the buyer's, and the top is exactly where the price moved. A working model, not proven law; it earns its keep in what it makes you measure.
Measure first, then rebuild
We do not know from here which stage of yours broke, and we will not guess. Deliverability failure, list decay, a message drifted from the buyer's stated pain: all three draw the same flat reply curve, and each has a different fix. So we measure where the selling breaks down first, on evidence you can check, before anything is rebuilt or sent.
When production restarts, it runs governed. Nothing goes out under your name without your approval, every opt-out is respected permanently, and volume rises only as fast as the evidence says the message lands.
If outbound used to work and quietly stopped, that is a measurable event, not a mystery. Book a GTM teardown and we will show you where the curve broke. The read is free and yours to keep, whoever does the rebuild.
