WhatsApp order notifications
Keep customers informed at every step — order confirmed, shipped, out for delivery — automatically, on the channel they actually read.
The problem
Email order confirmations get buried or land in spam. Customers message you asking "where is my order?" and your team copies status updates by hand. It does not scale and it frustrates buyers.
The solution
Trigger a WhatsApp message from your backend on every order event. WhatsApp open rates beat email by a wide margin, so confirmations and shipping updates are actually seen — with zero manual work.
How it works
Connect your store number once by scanning a QR code.
On each order event (paid, shipped, delivered), call the Vesper send endpoint.
Personalize the message with the order number, total, and tracking link.
Let customers reply — incoming replies arrive on your webhook so support can follow up.
