Senior Email Growth Manager, Outbound & Lifecycle

About Cosign

Cosign helps property owners approve more qualified renters by reducing application denials without increasing risk. We work with leading multifamily operators and are backed by some of the most respected investors and operators in real estate and technology.

About the Role

This is not a brand marketing, content marketing, social media, events, paid marketing, or generalist growth role. We are looking for an exceptional email operator who lives and breathes outbound email, deliverability, segmentation, campaign operations, and lifecycle email programs. Email is one of Cosign's most important go-to-market channels. C1/C2 English proficiency required. This role involves daily written and verbal communication with English-speaking management, vendors, and internal teams.

Our goal is to execute targeted sub-campaigns based on key market triggers such as occupancy changes, new supply, ownership changes, management changes, and other relevant signals. We are looking for someone who can build the systems, processes, segmentation, deliverability, and operational rigor required to make that possible.

This role requires someone who can bring order to complexity. As our email volume grows, success will depend as much on organization, campaign governance, audience management, data hygiene, and operational discipline as it does on messaging and campaign strategy. You will serve as the single owner of outbound email performance at Cosign, managing campaign execution, audience segmentation, deliverability, email infrastructure, data hygiene, personalization, and performance optimization.
