Diobox automatically manages the phone numbers used for both SMS and WhatsApp messaging. The sender number may vary depending on the message type, recipient location, and delivery method.
SMS Sender Numbers
Diobox automatically routes SMS messages through local phone numbers to improve delivery and support carrier compliance requirements.
Guests in different countries may receive messages from different local phone numbers. Using local numbers helps improve delivery rates and increases the likelihood that messages are successfully received.
This process is fully automatic and does not require any setup or number management from organizers.
WhatsApp Sender Numbers
WhatsApp messages are sent through Meta-approved WhatsApp Business phone numbers connected to Diobox.
Unlike SMS messaging, WhatsApp requires businesses to use verified WhatsApp Business Accounts and approved message templates. Messages are delivered directly within WhatsApp and may display business profile information associated with the sender number.
Diobox manages the WhatsApp infrastructure, Meta integration, and sender number configuration required for WhatsApp delivery.
