About The Position

Ruby Labs is seeking a results-obsessed Email Growth Manager to join their Email Marketing department. This role reports directly to the Marketing Director and is focused on driving conversion optimization and growth experimentation within email marketing. The primary objective is to grow email marketing as a conversion channel across all Ruby Labs brands, rather than executing day-to-day campaigns. The role involves generating hypotheses, designing A/B tests, analyzing results, implementing successful experiments, and studying the competitive landscape. The Email Growth Manager will collaborate with the Email Lead, Email Marketing Specialists, and the broader Marketing and Data teams to ensure actionable experiments and implemented insights lead to increased sign-ups and conversions.

Requirements

Minimum 3–5 years of experience in email marketing, growth marketing, or CRO, with a demonstrable track record of improving conversion metrics through experimentation.
Solid experience with Customer.io or equivalent email automation platforms (Klaviyo, Mailchimp, Brevo).
Proficiency in Mixpanel or similar analytics tools for experiment tracking and conversion analysis.
Strong understanding of A/B testing methodology, statistical significance, and experiment design.
Growth mindset with an obsessive focus on conversion metrics. You think in funnels, lift percentages, and test-learn-iterate cycles.
Highly analytical. You are comfortable pulling data, building reports, and making evidence-based decisions. You know the difference between a meaningful result and noise.
A natural ideator who generates a high volume of creative, testable hypotheses and knows how to prioritise them by potential impact.
Strong command of AI tools is a must. We expect this person to integrate AI into their daily workflow. From copy generation and experiment ideation to competitive research and data analysis. We leverage AI to maximize output and efficiency.
Excellent written and verbal communication skills in English.
Experience with subscription-based or direct-to-consumer digital products is required.
