SMS and WhatsApp Notifications: Settings and Costs
QrX sends messages to consumers over email, SMS, and WhatsApp. This article explains which messages exist, how merchants control them, and who pays for what.
Types of Messages
Payment messages: payment links, PIN codes, and payment confirmations. These are part of the core payment flow.
Verification messages: email or phone verification so payment information reaches the right person.
Track & Trace milestone notifications: optional delivery updates such as shipped, out for delivery, and delivered.
Payment SMS
Payment SMS messages are enabled by default and are required for a reliable payment flow, so they cannot be switched off by the merchant. QrX covers the cost of payment SMS unless your merchant agreement states otherwise.
Track & Trace SMS (Opt-In)
Milestone SMS notifications are off by default. A merchant can enable them per channel in the channel settings. Before enabling, PortalX shows a cost overview: the SMS carrier rate for each destination country plus a QrX platform fee of EUR 0.01 per SMS, together with a volume estimate based on your shipments.
A running "this month" SMS cost card in your settings shows what you have spent so far.
You can set a monthly SMS budget cap in EUR. When the cap is reached, milestone notifications automatically fall back to email for the rest of the month.
The cap never affects payment SMS: those are always delivered.
Where configured, QrX can deliver PIN codes and verification messages via WhatsApp in addition to SMS and email.
Consumer Opt-Out
Consumers can stop delivery-milestone notifications at any time via the unsubscribe link in an email or by replying STOP to an SMS. Payment and PIN messages are part of the payment flow and are always delivered.
