Email and SMS Marketing Manager

Job Description

Email & SMS Marketing Manager

Sleepyhead | Old Town Scottsdale, AZ | Full-Time, In-Office (Mon–Fri)

About Us

Sleepyhead is one of the fastest-growing brands in the sleep industry and was recently named to the Inc. 5000 list of America's fastest-growing private companies. We're a modern e-commerce company based in Scottsdale, shaking up the college sleep market with premium mattress toppers and sleep essentials. Our high-performance products, data-driven marketing and strong brand identity have built a loyal following of students, parents and young adults who love better sleep (and better design).

Role Overview

We're looking for a hands-on  Email & SMS Marketing Manager to own and grow our Klaviyo and Postscript channels. You'll run everything from strategy to execution: building campaigns and flows, sharpening segments, testing constantly, creating landing pages, and using the data to decide what comes next.

This role is for someone who rolls up their sleeves. You're as comfortable building a campaign yourself as you are planning one. You use AI tools to work faster and smarter, you take ownership of results, and you want to grow with a company that's scaling quickly.

\n

Segment, test, optimize

\n
• Build and refine customer segments and audiences to improve targeting and performance
\n
• Run ongoing A/B tests on subject lines, creative, offers, timing and messaging
\n

\n

Create

\n
• Write copy and produce email and SMS content
\n
• Work with our design team, adapt templates, or design your own assets when needed
\n
• Build and launch landing pages that support campaigns and conversion
\n

Analyze and report

\n
• Track and report on open rates, click-through rates, conversions, revenue and attribution
\n
• Turn performance data into clear insights and next steps
\n
• Spot opportunities to grow the channel and act on them
\n

Use AI and stay sharp

\n
• Use AI tools for copywriting, ideation, segmentation, analysis and workflow efficiency
\n
• Keep up with email, SMS and AI trends and bring new ideas to the team
\n

Collaborate

\n
• Work closely with the design, e-commerce and marketing teams to keep campaigns aligned with brand and business goals
\n

What You Bring

\n
• 2–3+ years of hands-on experience in email and/or SMS marketing, ideally in e-commerce or DTC
\n
• Direct experience running Klaviyo; Postscript experience is a strong plus
\n
• Proven track record of building segments, running tests and improving performance
\n
• Experience building landing pages (Shopify, page builders or similar)
\n
• Strong analytical skills and comfort working with campaign and revenue data
\n
• Comfortable using AI tools in your day-to-day work, and curious about how to use them better
\n
• Design skills in Canva, Adobe Creative Suite, Figma or similar
\n
• Strong writing skills and attention to detail, with an eye for brand consistency
\n
• Highly organized, able to manage multiple projects and deadlines
\n
• A strong work ethic: you show up, own your work and get things done
\n
• Bachelor's degree in Marketing, Communications, Business, Design or a related field, or equivalent experience
\n
• Must be comfortable working in-office Monday through Friday in Old Town Scottsdale
\n

What We Offer

• Ownership of a high-impact revenue channel at a fast-growing e-commerce brand
\n
• Hands-on work across email, SMS, creative, landing pages and analytics
\n
