    About Monmouth Cards

    Monmouth Cards is a fast-growing trading card and collectibles brand focused on scaling profitably through paid media and retention marketing. We’re looking for a performance-driven marketer who can fully own our paid ads and lifecycle marketing — from strategy to execution.

    This role is for someone who loves numbers, testing, and growth, but also understands brand, customer experience, and long-term LTV.

    What You’ll Be Responsible For

    Paid Advertising (Primary Focus)

    Own 100% of paid ad spend across:

    Google Ads (Search, Shopping, Performance Max, YouTube if relevant)

    Meta Ads (Facebook & Instagram)

    Plan, launch, and optimize campaigns to hit ROAS, CAC, and growth targets

    Manage budgets, scaling winners and cutting losers quickly

    Creative testing strategy (copy, hooks, angles, offers) — working with our team or creatives as needed

    Build and optimize audiences, retargeting, and attribution logic

    Weekly reporting with clear insights, not vanity metrics

    Email & SMS Marketing (Klaviyo)

    Fully manage Klaviyo email + SMS

    Build, optimize, and maintain:

    Core flows (Welcome, Abandoned Cart, Browse Abandonment, Post-Purchase, Winback, etc.)

    Campaigns tied to promos, drops, and seasonal pushes

    Improve revenue per subscriber, open rates, CTR, and unsubscribe rates

    Segment intelligently based on behavior, purchase history, and engagement

    Ensure email & SMS align with paid traffic and overall funnel strategy

    Strategy & Optimization

    Take a full-funnel view: acquisition → conversion → retention

    Identify opportunities to improve LTV and overall marketing efficiency

    Run A/B tests across ads, landing pages, and lifecycle messaging

    Stay on top of platform changes (Meta, Google, deliverability, etc.)

    What We’re Looking For

    Proven experience managing Google Ads + Meta Ads for eCommerce brands

    Strong hands-on experience with Klaviyo (email + SMS)

    Data-driven mindset — you make decisions based on performance, not vibes

    Comfortable owning results end-to-end (not just “running ads”)

    Strong understanding of ROAS, CAC, LTV, attribution, and scaling

    Bonus: experience in collectibles, trading cards, or hobbyist eCommerce

    Nice-to-Haves (Not Required)

    Experience with Shopify

    Creative strategy experience (angles, offers, UGC direction)

    Familiarity with GA4, Triple Whale, or other attribution tools

    Copywriting chops for ads, email, or SMS

    What Success Looks Like

    Profitable, scalable paid ad performance

    Strong email & SMS revenue contribution

    Clean, well-documented campaigns and flows

    Clear communication and proactive optimization ideas

    You treat the ad spend like it’s your own money

    Why Work With Us

    Real ownership and impact — no red tape

    Room to grow with the brand

    Competitive pay based on experience

    Flexible, remote-friendly work environment
