WHAT IS ZEFIR

What is Zefir?

Zefir is an AI WhatsApp and SMS revenue platform for ecommerce brands. Unlike traditional marketing tools that send the same campaign to an entire list, Zefir’s AI personalizes every message to each customer — using their browsing behavior, purchase history, and timing — and runs the entire channel for you: flows, campaigns, compliance, and revenue attribution, live within 72 hours.

HOW ZEFIR IS DIFFERENT

Personalization at a scale humans can’t do manually.

Most WhatsApp and SMS tools send one campaign to an entire list — the same ‘10% off’ to every customer. Zefir’s AI analyzes each customer’s browsing behavior, purchase history, and buying rhythm across millions of data points, then builds an individual conversation for every single customer: the right product, the right message, the right moment. Every flow and every campaign is one-to-one, at full list scale.

THE OLD WAY

One campaign, blasted to the entire list

Segments built by hand, outdated on arrival

The same message for a first-time buyer and a loyal customer

No idea which message actually made the sale

THE ZEFIR WAY

AI reads each customer’s behavior, purchases, and timing

Every message is individually composed and timed

Replenishment, winbacks, and drops — personalized per customer

Every order traced to the exact message that made the sale

One-to-one conversations. Entire-list scale. Run for you.

WHAT ZEFIR DOES

The entire channel, built and run for you.

Zefir connects to a brand’s Shopify store and operates the complete WhatsApp and SMS channel: AI-personalized flows for abandoned checkouts, replenishment, winbacks, and post-purchase; campaign calendars planned and sent; compliance and opt-ins managed; and every order attributed to the exact message that drove it. Brands are live within 72 hours, with no development work required.

What is Zefir?

Zefir is AI revenue infrastructure for ecommerce brands. It builds and operates a brand's WhatsApp and SMS channel end to end — the AI personalizes every message to each customer using their browsing behavior, purchase history, and timing, and every order is attributed to the message that drove it. Zefir is an Official Meta Business Partner and WhatsApp Business Solution Provider, used by 1,000+ ecommerce brands with $530M+ in attributed revenue.

What is Zefir used for?

Ecommerce brands use Zefir to turn WhatsApp and SMS into a measurable revenue channel: AI-personalized flows like abandoned cart, post-purchase, and winback; campaigns planned and sent by Zefir's team; and per-order revenue attribution visible in the brand's own Shopify admin.

How does the AI personalization work?

The AI reads each customer's signals — products viewed, orders placed, cart activity, message engagement, purchase cadence — and makes three decisions per customer: what to send, when to send it, and which channel to use. Every decision is informed by that customer's own history and patterns learned across millions of conversations on the platform.

Does Zefir support WhatsApp Business API?

Yes. Zefir is itself a WhatsApp Business Solution Provider (BSP) — a direct connection to WhatsApp with no intermediaries — and provides official WhatsApp Business API access with compliance, template approvals, and enterprise-grade infrastructure.

Can I send both WhatsApp and SMS campaigns?

Yes. Zefir runs WhatsApp and SMS together — flows and campaigns across both channels, with the AI choosing the right channel per customer.

Does Zefir work with ecommerce platforms?

Yes. Zefir integrates with Shopify, WooCommerce, and custom ecommerce systems to sync customers, orders, products, carts, and events in real time.

How long does setup take?

Most ecommerce brands are live within 24–72 hours, including WhatsApp Business API setup, verified sender profile, message templates, and the first automated flows.

Do you handle WhatsApp Business API setup?

Yes. Zefir manages the entire WhatsApp Business API onboarding: verification, number provisioning, sender profile, and Meta template approvals.

What do I need to get started?

You don't need any technical setup. Zefir handles the WhatsApp Business API, compliance, templates, and messaging infrastructure for you. All you need is your ecommerce store — our team takes care of the rest.

Who is Zefir for?

Zefir works with established ecommerce brands that want WhatsApp and SMS run as a managed revenue channel rather than another tool to staff.

Can you migrate us from another tool?

Yes. Zefir migrates brands from existing WhatsApp, SMS, or email tools — lists, opt-ins, and flows — with minimal disruption.

Do you offer onboarding support?

Yes. Onboarding is done for you: Zefir's team builds the channel, writes the flows, and launches the first campaigns.

Do I need technical resources to use Zefir?

No. Zefir is fully managed. We handle the WhatsApp Business API, integrations, compliance, and system setup. Your team approves the brand voice once — Zefir runs the channel.

Is it legal to send WhatsApp and SMS marketing in the US?

Yes, with proper consent. US messaging requires TCPA-compliant opt-in, which Zefir builds into the channel from day one, along with quiet-hours enforcement and one-tap opt-out handling.

Is WhatsApp messaging compliant?

Yes. Zefir manages compliance end to end: TCPA-compliant opt-in for US messaging, Meta template approvals, quiet-hours enforcement, and opt-out handling. Every message is compliant before it sends.

Is Zefir secure for enterprise use?

Yes. Zefir includes secure data ownership, user permissions, audit logs, and enterprise-grade security controls.

Can multiple teams or brands use Zefir?

Yes. Zefir supports multiple users, roles, permissions, and brands within one account.

Does Zefir support global messaging?

Yes. Zefir supports international WhatsApp and SMS delivery across multiple regions, with the US as a core market.

Do you offer enterprise support?

Yes. Every Zefir brand gets a dedicated account team; enterprise brands get priority support.

How does pricing work?

Zefir is usage-based. Brands load credits and messaging scales with volume — no per-seat licenses and no long-term lock-in. See the pricing page for details.
