About the role
Ruby Labs is looking for a results-obsessed Email Growth Manager to join our Email Marketing department and report directly to the Marketing Director. This is a high-impact, data-driven role built for someone who lives and breathes conversion optimisation and growth experimentation.
Unlike traditional email marketing roles, your mandate here is singular: grow email marketing as a conversion channel across all Ruby Labs brands. You will not be executing campaigns or managing day-to-day flows,iInstead, you will be the engine behind our experimentation culture. Your days will be spent generating hypotheses, designing A/B tests, analysing results, rolling out winners at scale, and obsessively studying the competitive landscape to identify opportunities we haven't explored yet.
You will work closely with the Email Lead, Email Marketing Specialists, and the broader Marketing and Data teams to ensure every experiment is actionable, every insight is implemented, and every winning idea moves the needle on sign-ups and conversions.
Key Responsibilities
Conversion Growth Strategy: Develop and maintain a structured experimentation roadmap, continuously generating and prioritising hypotheses to improve email conversion rates and grow email marketing as a sign-up channel across all Ruby Labs brands.
A/B Testing & Experimentation: Ideate, design, and launch A/B and multivariate tests on subject lines, preview text, email copy, CTAs, send times, sequences, and full funnel flows, with a relentless focus on improving conversion metrics.
Results Analysis & Rollout: Analyse test results with statistical rigour, extract clear insights, document learnings, and roll out winning experiments across all brands at scale.
Competitive Intelligence: Continuously monitor competitors' email strategies. Including their flows, offers, messaging, frequency, and design, to identify trends, gaps, and opportunities for Ruby Labs to capitalize on.
Email Sequence Ideation: Conceptualise and propose new email sequences, lifecycle flows, and campaign structures focused on driving sign-ups and conversions, collaborating with the email team on implementation.
Performance Ownership: Track, report on, and own key growth KPIs including conversion rate, sign-up share from email, revenue per email, and lift from experiments.
Cross-functional Collaboration: Work closely with the Email Lead, Email Marketing Specialists, Marketing Director, and Data Analysts to align on growth priorities and ensure experiments are properly instrumented and measurable.
Tool Utilisation: Identify and leverage opportunities within our email tooling (Customer.io, Mixpanel) to unlock new testing and segmentation capabilities that support growth goals.
Qualifications
Experience: Minimum 3–5 years of experience in email marketing, growth marketing, or CRO, with a demonstrable track record of improving conversion metrics through experimentation.
Technical Skills:
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 Orientation: Growth mindset with an obsessive focus on conversion metrics. You think in funnels, lift percentages, and test-learn-iterate cycles.
Data-Driven Thinking: Highly analytical. You are comfortable pulling data, building reports, and making evidence-based decisions. You know the difference between a meaningful result and noise.
Creative Hypothesis Generation: A natural ideator who generates a high volume of creative, testable hypotheses and knows how to prioritise them by potential impact.
AI Proficiency: 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.
Communication: Excellent written and verbal communication skills in English. Ability to write clear, compelling email copy for test variants is a strong advantage.
Experience with Digital Products: Experience working with subscription-based or direct-to-consumer digital products is required.
