Client Delivery Project Manager, Email Marketing

Client Delivery Project Manager, Email Marketing

Remote, Full-Time. EST overlap required.

The role

Mail Waves helps eCommerce brands grow through high-performing lifecycle strategy, creative testing, and consistent execution in Klaviyo. We are hiring a senior, client-facing leader who can run a portfolio, lead a small delivery team, and confidently manage stakeholders.

This is not a junior production role. You will own client outcomes, lead meetings, direct internal specialists, and create clarity when priorities shift.

What you will own

Client leadership and retention

• Serve as the primary strategic contact for a portfolio of eCommerce retainer clients.
• Lead weekly client calls, drive clear agendas, and control next steps.
• Run quarterly strategy reviews, performance reporting, and roadmap planning.
• Manage escalations with calm, direct communication and fast resolution.
• Protect scope, manage expectations, and keep accounts healthy.

Lifecycle strategy in Klaviyo

• Set lifecycle strategy across flows, campaigns, segmentation, and testing.
• Translate performance into decisions using revenue attribution, deliverability signals, engagement trends, and offer performance.
• Partner with creative and copy to develop briefs that convert, then iterate based on results.
• Ensure clean QA across links, tracking, dynamic content, brand voice, and compliance.

Team leadership and delivery management

• Lead and coordinate a pod of specialists (Klaviyo builders, copy, design).
• Assign work, unblock execution, and enforce quality standards.
• Hold weekly internal production reviews, prioritize workload, and keep timelines tight.
• Coach team members through feedback, reviews, and performance expectations.

Systems and process ownership

• Own ClickUp workflows for your accounts, including task quality, timelines, and visibility.
• Identify bottlenecks and implement better SOPs, templates, and QA systems.
• Raise the bar on how the agency communicates, reports, and ships work.

Minimum requirements (do not apply without these)

• 4+ years in email and lifecycle marketing for eCommerce brands.
• 2+ years managing clients in an agency or retainer environment.
• 1+ years leading a team, pod, or cross-functional delivery group.
• Strong Klaviyo experience across flows, campaigns, segmentation, deliverability basics, and reporting.
• Confidence presenting performance and strategy to founders and senior marketers.
• Strong written communication. You can turn messy inputs into clear plans.

Strongly preferred

• Experience owning 10 to 20 concurrent retainers, with high-quality client communication.
• Experience improving retention, reducing churn, and expanding accounts through strategy.
• Familiarity with Shopify, eCommerce offers, and typical DTC buying cycles.
• Mailchimp familiarity is a plus.
• Comfort using AI tools to speed up analysis, QA, and planning.

Working hours

• Full-time with meaningful overlap with EST business hours.

If you’re the kind of leader who loves turning chaos into clean execution, this role will feel like home. You’ll run delivery across a talented pod, lead client conversations with confidence, and drive real growth for eCommerce brands through lifecycle marketing that performs. If you want ownership, autonomy, and a team that moves fast, apply today.
