The Challenge
SIG Partners is a $290M+ acquisition machine that needs you to architect and scale a cold email operation from 800K to 1M sends per month. You'll own the entire deliverability stack—infrastructure, list hygiene, sequences, reporting—and report directly to the CMO.
Your Mission
Stand up domain and mailbox provisioning pipeline; achieve 95%+ deliverability across all sending domains within 60 days
Implement weekly list hygiene process (deduplication, suppression management, QA) aligned to campaign cadence
Build and deploy 4-6 initial email sequences in SmartLead with baseline A/B testing framework
Deliver weekly deliverability and performance reports tracking sends, opens, replies, bounces, and spam metrics
Sustain 1M+ cold emails per month at 95%+ deliverability with zero manual bottlenecks in domain/mailbox rotation
Establish data quality SLA with AI Engineer; flag and resolve upstream list issues; reduce bounce rate by 15%
Run minimum 12 A/B tests across subject lines, send times, copy, and sequence structure; implement winning variants
Contribute measurable pipeline value; report on reply-to-qualified-lead conversion; optimize sequence kill/pause criteria
KPIs You'll Own
Deliverability Rate
Maintain inbox placement above 95% across all sending domains; monitor bounce rates, spam traps, and blacklist status weekly.
Send Volume & Capacity
Scale to 1M+ cold emails per month without manual bottlenecks; track domain and mailbox utilization.
Reply Rate & Positive Response %
Measure email reply rates and conversion to qualified pipeline; tie sequence performance to BDR handoff.
Data Quality Score
Track list hygiene metrics—deduplication effectiveness, suppression list accuracy, and upstream issue flagging.
Pipeline Contribution
Connect cold email performance to business development pipeline; measure cost per qualified reply and downstream conversion.

Is This Role For You?
- You've scaled email infrastructure or managed high-volume cold email operations; you understand DNS, IP warming, ESP configuration, and deliverability mechanics
- You're obsessed with data quality and ops rigor; you can build repeatable processes and flag upstream issues without hand-holding
- You want ownership end-to-end—from domain provisioning through weekly reporting—reporting to a CMO who trusts you to own the channel
- You thrive in a B2B outbound environment; you see cold email as a scalable, measurable system, not a guessing game
- You're based in Dallas or willing to relocate; on-site culture matters to this team
- You need remote flexibility or can't commit to on-site in Dallas—this role is in-office only
- You lack hands-on experience with ESP tools (SmartLead, Outreach, etc.) or email infrastructure; this is not a management-only role
- You expect immediate equity or variable comp; this is a base salary role with no mention of bonus or equity upside
- You prefer working solo; this role requires tight cross-functional coordination with AI, BDR, and business development teams
Interview Process
Initial Screening

Technical Deep Dive
Whiteboard or written exercise on email infrastructure design (domains, IP warming, DNS, ESP configuration) at 1M+ scale
