Notifications Overview

Everything Timesact sends to your customers: what triggers each message, the three channels you can send through, and where to set each one up. You choose the channel per feature, per customer experience template, so different products can be handled differently.

The events Timesact sends

• Back in stock, subscribed — a shopper submits the Notify Me form. Goes to that shopper.
• Back in stock, ready — a subscribed variant is restocked. Goes to each waiting subscriber (once per subscriber).
• Pre-order confirmed — a customer places an order containing a pre-order item. Goes to that customer.
• Pre-order shipping delay — you trigger it manually from Reports → Sales (select orders, then Send shipping delay emails). Goes to each affected customer.

The three channels

You send through one of three channels. Each has its own setup article:

• Built-in — Timesact sends transactional emails for you, using templates you edit in the app. Best when you do not have a marketing platform yet. See Notifications - Built in.
• Shopify Flow — Timesact fires a Flow trigger and you build the email (or any action) inside Shopify Flow. Best when you already automate in Flow. See Notifications - Shopify Flow.
• Klaviyo — Timesact emits events to Klaviyo and your Klaviyo flows take over. Best when you run your email program in Klaviyo. See Notifications - Klaviyo.

Which channels each feature supports:

• Pre-order: Built-in or Klaviyo.
• Back in stock: Built-in, Shopify Flow, or Klaviyo.

Shopify Flow is currently available for back-in-stock only, which is why it does not appear on the Pre-Order tab.

Choosing a channel

Inside a customer experience template, open Notifications (left menu, under Admin). There is a tab per feature (Pre-Order, Back in Stock, Coming Soon). On each tab, pick the channel:

• Built-in notifications — no extra setup, emails send automatically.
• Shopify Flow — (Back in Stock only) fires Flow triggers instead of sending built-in emails.
• Klaviyo — emits events to Klaviyo. When selected, an Available events panel lists exactly which events that feature emits (for example "Preorder Confirmed" on Pre-Order, or "Back in Stock Subscribed" and "Back in Stock Ready" on Back in Stock), which you use as triggers in your Klaviyo flows.

Routing is per feature, per template, and independent. One template can be on Klaviyo while another is on built-in.

Newsletter checkbox, by channel

The Notify Me form has an optional "Subscribe to our newsletter" checkbox you can enable per experience. When a shopper ticks it:

• Klaviyo — the profile is auto-subscribed to your account's default opt-in (respects your double opt-in setting if configured).
• Shopify Flow — the trigger carries a Subscribed to Newsletter boolean; you decide what to do with it.
• Built-in — consent is stored but no automatic list subscription happens (built-in is transactional only).

FAQ

Can I use multiple channels at once? No, one channel per feature per experience. To get both an internal action and Klaviyo, route to Klaviyo and add the action inside your Klaviyo flow.

Will switching channels double-email customers? No, already-sent notifications are not resent; switching only affects future events.

How do I test before going live? Built-in has Send Test on each template; Flow and Klaviyo have their own preview and test tools.
