Keep every order in the conversation.

Connect your storefront events to SMS, email, and RCS for order updates, delivery notifications, and consent-based customer campaigns.

Your store knows when an order changes. Connect those events to Blocx so customers hear from you at the right moment.

Keep customers informed from order confirmation to their next visit, using the events your store already knows.

The questions every order creates

The purchase ends, but the questions begin

Customers want to know whether the order is confirmed, what changed, and where to look next. A vague notification creates another support conversation.

Delivery changes reach customers too late

Your fulfillment systems may already know about an exception while the customer is still working from an old email or an expected delivery date.

Every promotion starts to sound the same

A cart follow-up, a restock notice, and a new collection announcement are different reasons to contact someone. Relevance starts with the right event and permission.

From checkout to the next visit

Follow each stage from the event in your system to the message your customer receives and the next action in your product.

Confirm the purchase with a useful destination

Send a concise confirmation once your order system records the order. Make it easy to return to the customer's own order details.

Your event
Order confirmed
Channel
SMS

Order confirmed. Open your store account to review your items and current delivery information.

Next step: View the confirmed order in your storefront.

Make shipment progress easy to follow

Connect a shipment event to a short update rather than making the customer repeatedly check for a change.

Your event
Shipment created
Channel
SMS

Your order is on its way. Open your store account for the latest shipment information and delivery updates.

Next step: Open the order's shipment details.

Explain a delivery change before it becomes a complaint

Use verified fulfillment data to explain what changed and where the customer can see the current information.

Your event
Delivery schedule changed
Channel
SMS

There is an update to your delivery schedule. Open your store account to review the latest information or contact support.

Next step: Review current delivery information or ask for help.

Return shoppers to the cart they recognize

Follow eligible abandoned-cart events with a clear route back to the actual basket. Exclude completed purchases and recipients without the required permission.

Your event
Eligible cart remains incomplete
Channel
SMS

Your saved basket is waiting. Sign in to review your items and continue checkout. Reply STOP to opt out.

Next step: Resume the current cart, not a generic storefront page.

Act on a request, not a guess

Notify people who asked to hear about availability when your inventory system confirms an eligible item is back.

Your event
Requested item available again
Channel
SMS

An item you asked about is available again. Visit your store account to review current availability. Reply STOP to opt out.

Next step: Review the requested item's current availability.

Connect the events your store already knows

Connect order, cart, and inventory events

Use your storefront or backend as the source of truth for order state, timing, and customer permissions.

Prepare the right message and destination

Include accurate order context and links generated by your own store. Choose an eligible channel and keep private details behind the account.

Bring delivery feedback back to support

Store message identifiers with the order or customer record. Process documented status events so support can distinguish a submitted notification from a delivered message.

Relevant messages, accurate order information

Do not turn service notices into surprise marketing

Apply the right consent and opt-out rules to promotional follow-ups rather than treating a purchase as blanket marketing permission.

Let the store own eligibility

Suppress a cart reminder when checkout completes, and confirm inventory before sending a restock notice.

Match channels to the plan and content

MMS and RCS require Scale or Volume. Carrier and content restrictions still apply, including restricted-industry review where relevant.

Integration requirements

Your storefront supplies the events and customer permissions. Review consent and carrier requirements before sending campaigns.

Connecting your storefront

Is Blocx a storefront or order-management integration?

Blocx is the messaging layer. Your store or integration supplies order, fulfillment, cart, and inventory events and submits the appropriate messages. This page does not promise a prebuilt integration with a particular commerce platform.

Can I send order updates and marketing through Blocx?

Yes, using the supported channels and your plan's capabilities. Keep service notifications and promotional campaigns under their respective consent and sending rules rather than treating them as the same type of message.

Where do tracking and checkout links come from?

Your storefront and fulfillment systems generate those destinations. Blocx delivers the content you submit; it does not create shipment data or maintain the customer's cart.

Can I use richer messages?

MMS can carry supported media, and RCS supports richer messaging where available. Both require Scale or Volume, and content, carrier eligibility, sender setup, and recipient support still matter.

Will this guarantee more recovered carts or fewer support tickets?

No fixed commercial result is promised. The integration gives you a way to make existing events visible and actionable; you decide eligibility, timing, message quality, and how to measure the outcome.

Give the next order event a clear customer message.

Begin with the order question your support team hears most often, then connect that event to a message and a useful account destination.
