Email & SMS Marketing Manager at DTC E-commerce Portfolio; Remote

Position: Email & SMS Marketing Manager at DTC E-commerce Portfolio (Remote, US-based)
About Our Clients

Our client manages a portfolio of four consumer brands spanning home fragrance, energy bars, men's grooming, and better-for-you snacks.

These brands operate in the direct-to-consumer (DTC) e-commerce space, with a significant portion of revenue coming from subscriptions. Email and SMS marketing play a critical role in customer onboarding, retention, and long-term customer value.

We are looking for a hands-on Email & SMS Marketing Manager to own email and SMS execution across its portfolio.

This role reports directly to the Head of Retention, who oversees overall strategy and performance targets.

The ideal candidate is someone who works directly inside Klaviyo every day, personally building flows, segments, templates, campaigns, and automation. You will also own SMS execution end to end.

This is an individual contributor role, not a team management or agency management position.

We are specifically looking for someone who builds and executes campaigns themselves rather than directing others to do the work.
