About the role

We're looking for a super hero, hands-on Senior Email Marketing Manager to own and scale our email marketing program for a fast-growing online social sweepstakes casino platform. You'll be responsible for managing a large, segmented user base, running daily broadcast campaigns, and continuously improving conversion through data-driven testing — all within Customer.io.

This is a high-ownership role for someone who has done this exact job before in the online casino/gaming industry and can hit the ground running from day one.

Key Responsibilities

• Own the end-to-end email marketing strategy and execution

• Manage promo plan with the emails and offers being sent out on a daily/weekly basis

• Secure 0 days of downtime with the email broadcasting

• Grow email database almost from the ground zero toward 10M+ contacts, and manage it at that scale — including acquisition, deliverability, list hygiene, and compliance

• Build and maintain deep audience segmentation (10–15+ segments) based on lifecycle stage, deposit status (FTD/no FTD), VIP tier (Bronze, Silver, Gold, Emerald, Diamond, etc.), and behavioral signals

• Plan and launch daily broadcast campaigns across the entire segmented database — including time-sensitive/expiring offers

• Coordinate closely with design/creative to ensure offer emails are on-brand, visually consistent, and shipped on a daily/weekly cadence

• Maintain detailed logs and reporting of every broadcast sent (open rate, click rate, conversion, revenue per segment)

• Analyze campaign performance weekly, generate hypotheses, and continuously test subject lines, offers, send times, and segment logic to improve conversion rate

• Work cross-functionally with product, CRM/lifecycle, design, and community management to align email with pushes, SMS, and other channels

• Present weekly performance reviews and improvement plans to leadership

Qualifications

• Fluent English

• Minimum 2 years of recent, hands-on experience with Customer.io

• Minimum 3 years of experience working specifically in email marketing for online casino / iGaming / social casino brands

• Experience working with an email database with 10M+ contacts, including hygiene, and deliverability management at scale

• Demonstrated experience building and managing deep user segmentation (10–15+ live segments simultaneously, e.g., by VIP tier, deposit status, lifecycle stage)

• Experience running daily email broadcasts to a fully segmented database (not just occasional campaigns)

• Strong understanding of casino/gaming lifecycle marketing: FTD (first-time deposit) conversion, VIP tiering, re-engagement, and expiring/time-sensitive offers

• Experience coordinating email with other channels (push, SMS, in-app) as part of a unified promo calendar

• Experience setting up A/B tests for subject lines, send times, and offer creatives
