AI-powered email marketing design and copy tool for e-commerce brands and agencies.

freemium· from $0/mo· for mid-market

Mailsplash generates on-brand email campaigns — both copy and visual design — for ecommerce retention teams and agencies managing multiple client accounts. Operators feed brand guidelines once, then produce welcome flows, promos, and win-back sends without routing every asset through a designer. The tool exports into existing ESPs rather than replacing Klaviyo or Braze, positioning it as a production layer for lifecycle marketers who need weekly campaign volume without proportional headcount.

> pick this if

Pick this if you're a lifecycle team or retention agency producing high campaign volume on Klaviyo/Omnisend/Attentive and want to remove the designer bottleneck without swapping ESPs.

> look elsewhere if

Look elsewhere if you need deep segmentation logic, A/B orchestration, or SMS/push automation — Mailsplash is a creative production layer, not an ESP or a full lifecycle platform.

> how you'd use it

  • DTC apparel brand, $3M–$15M GMV, 2-person lifecycle team
    Weekly promo calendar plus evergreen welcome and win-back flows in Klaviyo — the team was bottlenecked waiting on a freelance designer for every send
    Cuts campaign production from 3–4 days to same-day, holds brand consistency via uploaded style guide, and lets one marketer ship 4–6 sends per week without external design spend
  • Retention agency managing 10–25 ecommerce clients, 5–15 strategists
    Per-client brand profiles feed templated copy and graphics across different ESPs (Klaviyo, Omnisend, Attentive), with strategists reviewing before export
    Raises campaigns-per-strategist throughput roughly 2x, reduces reliance on in-house designers, and makes junior hires productive on client work in weeks rather than months
  • Early-stage Shopify brand, <$1M GMV, founder-led with no marketing hire
    Founder runs promos and abandoned-cart flows personally on the freemium tier before committing to a retention hire
    Produces passable on-brand sends without a designer or copywriter, validating email as a channel before budgeting for Klaviyo agency retainers
