THE OPPORTUNITY

We’re looking for an Email Copywriter who can think beyond writing emails.
This role combines strategy, research, and copywriting. You’ll be responsible for understanding each client’s business, identifying opportunities within their email marketing, building effective email strategies, and writing copy that drives measurable results.
You’ll work closely with Customer Success Managers, Klaviyo Managers, and Designers to create high-performing campaigns and automations for multiple eCommerce brands across different industries.
We’re looking for someone who doesn’t just ask, “What should I write?” but instead asks, “What’s the best strategy to grow this brand?”

WHAT YOU’LL DO

Brand Research & Strategy
Research and understand each client’s brand, products, audience, competitors, and market positioning.
Audit email accounts to identify gaps, opportunities, and areas for improvement.
Build email marketing strategies tailored to each client’s goals.
Create lifecycle flow structures and recommend the right automations for new brands.
Plan monthly campaign calendars with a balance of promotional, educational, retention, and relationship-building emails.
Understand customer lifecycle marketing and recommend strategies for subscription-based and retention-focused brands.
Stay updated on industry trends and continuously bring new strategic ideas to the team.
Email Copywriting
Write persuasive, conversion-focused copy for email campaigns and automated flows.
Create copy for promotional campaigns, launches, newsletters, seasonal sales, abandoned cart flows, welcome series, win-back campaigns, and retention sequences.
Adapt your writing style to different brand voices and audiences.
Balance creativity with business objectives and clear calls-to-action.
Write copy based on thorough research rather than assumptions.
Collaboration & Execution
Collaborate closely with Customer Success Managers, Klaviyo Managers, and Designers to execute client strategies.
Translate campaign briefs into engaging, high-converting email copy.
Suggest strategic improvements rather than simply following instructions.
Participate in brainstorming sessions and contribute ideas for improving client performance.
Revise and optimize copy based on internal reviews, testing, and client feedback.
Optimization & Performance
Understand email marketing best practices, including segmentation, deliverability, engagement, and list health.
Analyze campaign performance and recommend improvements.
Support A/B testing initiatives by suggesting new messaging angles and creative approaches.
Ensure all emails maintain consistent brand voice, quality, and accuracy.
Continuously improve copy based on data, customer behavior, and performance insights.

WHAT WE’RE LOOKING FOR

Experience & Skills
2+ years of experience in Email Copywriting, Email Marketing, or Retention Marketing.
Strong understanding of customer psychology, persuasive writing, and brand voice.
Experience building email strategies, not just writing copy.
Understanding of customer lifecycle marketing and eCommerce email funnels.
Familiarity with Klaviyo and email marketing best practices.
Strong research and analytical skills.
Excellent written English with exceptional grammar and attention to detail.
Comfortable working across multiple brands simultaneously.

How You Work

You think strategically before writing.
You enjoy researching brands and identifying growth opportunities.
You take ownership and proactively suggest improvements.
You communicate clearly with both clients and internal teams.
You’re organized, proactive, curious, and comfortable working in a fast-paced agency environment.
You’re comfortable receiving feedback and iterating quickly.

WHY MACH33?

At Mach33, you’ll work with a high-performing remote team that values ownership, strategic thinking, and continuous learning.
You’ll gain hands-on experience building email strategies for international eCommerce brands, collaborate with experienced marketers, and directly influence client growth through both strategic planning and high-converting copy.
