Reach customers where they actually read.
In India, Brazil, the Middle East, and Southeast Asia, WhatsApp is the primary messaging channel. Open rates exceed 95%. If your customer base lives there, transactional email is leaving conversions on the table.
The problem
International stores often see strong sales in markets where email isn't the default communication channel. Reminders sent via email there go unread, customers worry about delivery, support tickets pile up.
How it works
Step by step.
No code, no developer required. Drop the ShipCast block into your theme and the feature lights up.

For production, register a transactional template in Twilio Console → get a ContentSid.

Paste the ContentSid into ShipCast.

ShipCast sends WhatsApp messages with order details substituted into your approved template.

Customers receive a WhatsApp notification 1 day before estimated delivery.

ProCut "where's my order?" tickets with SMS reminders
When a customer doesn't know if their package is coming today or next week, they email support. Multiply by every order and that's a meaningful weekly cost. A single SMS — "Your order arrives tomorrow!" — eliminates the question before it gets asked.

ProShow customers their return deadline automatically
"What's your return policy?" is one of the top three pre-purchase questions. "When does my return window close?" is one of the top three post-purchase tickets. A concrete date — "Easy returns until April 5" — on every order confirmation eliminates both.

ProDifferent cutoffs, different timezones, same store
A 2pm cutoff in New York and a 2pm cutoff in Los Angeles are three hours apart. Most apps ignore this and show one cutoff time across your whole store, which means half your customers see the wrong countdown. ShipCast routes each customer to the right warehouse and shows the right promise.
