B2B Cold Email Service Delivery Master

We run done-for-you cold email systems for B2B clients (SaaS, IT services/MSP, marketing agencies, staffing/recruiting, financial services). We're hiring a service delivery freelancer (or small team) to fully run client accounts once a client signs on, covering everything included in our packages (5,000–30,000 leads/month; email-only up to multi-channel at our top tier). You'll be responsible for, per client account: • Signal-led lead data & enrichment (list volume scales with the client's package tier). • Persona-specific copy & personalization, tailored per ICP, not generic templates. • Domains & inboxes — warmup, rotation, ongoing monitoring. • Deliverability ops — seed tests, send throttles, fixes. • Campaign launches & daily tuning. • Reply desk — human qualification of replies and calendar booking. • Testing & optimization. • Reporting — live dashboards, CRM sync, Slack alerts. • Contributing to weekly/fortnightly/monthly strategist check-ins/insights for the client. You have: • Proven B2B cold email experience end-to-end, list building through reply handling, not just one slice of the process. • Comfortable owning client-facing communication (replies, booking) as well as the technical side. • Strong capability using Clay as we run client campaigns from this software, we care about results. • Portfolio experience in any of our core verticals is a strong plus: SaaS, IT services/MSP, marketing agencies, staffing/recruiting, or financial services (PREFERRED). • Reliable, detail-oriented, comfortable with async reporting. Structure: Ongoing monthly retainer per client account you deliver, scaling as we onboard more clients. Month-to-month.
