Who this is for

  • D2C brands with SMS opt-ins sitting idle in a CDP or ESP.
  • Subscription and replenishment brands where SMS reminders move conversion.
  • Lifecycle leaders who need SMS coordinated with email and WhatsApp.
  • Brands hit by carrier filtering, low click-through, or compliance scares.

What you get

  • SMS strategy - audience map, journey design, cadence rules, and KPI targets per stage.
  • Automation builds - welcome, post-purchase, abandoned cart, replenishment, win-back, VIP, and back-in-stock journeys.
  • Compliance setup - TCPA, GDPR, and double opt-in patterns. Quiet hours, consent capture, and unsubscribe handling.
  • Personalization - behavioral and lifecycle-stage personalization. Dynamic content blocks where supported.
  • Copy and content - punchy, action-driving copy under platform character limits. Link shorteners, UTM hygiene.
  • Reporting - attributable revenue per send, opt-in growth, opt-out rate, click-through, and lifecycle stage performance.

Talk to a specialist
What does an SMS marketing agency actually deliver?
Strategy, journey builds, copy, compliance setup, segmentation, and reporting - across welcome, post-purchase, cart, replenishment, win-back, and broadcast.
Klaviyo SMS vs Postscript vs Attentive - which one should we pick?
Klaviyo SMS for brands already on Klaviyo email. Postscript for Shopify-first D2C with deep automation needs. Attentive for high-volume D2C with managed-service preferences.
How long does an SMS program take to ship?
A focused journey suite (welcome, cart, post-purchase, win-back) ships in 4-8 weeks.
How much do SMS marketing services cost?
Retainer engagements typically start in the low five figures monthly and scale with send volume and platform fees. Project builds quoted separately.
How do you handle compliance?
Every program ships with TCPA / GDPR audit, double opt-in or single opt-in per region, quiet hours, and clear unsubscribe - plus a compliance owner during ongoing operations.
Will SMS cannibalize my email revenue?
No, when orchestrated. SMS and email serve different moments. Coordinated cadence increases attributable revenue across both channels.
Can SMS run alongside WhatsApp?
Yes. We coordinate channels by audience preference and journey stage.
How is H4H different from a Postscript or Attentive partner agency?
Tool partners specialize in one platform. We pick the platform by fit and run SMS as part of the broader lifecycle program.
