Personalization with variables
Personalization with variables is the insertion of dynamic fields into a message's text, such as the recipient's name, order number, appointment date or amount. At send time, each variable is replaced with the individual contact's real data: everyone receives the same template, but each person reads a message built on their own data. In WhatsApp templates, variables are numbered placeholders.
Effective personalization uses data that genuinely changes the content: a reminder with the appointment's date and time is information, a greeting with the name is cosmetics. The most useful variables in conversational marketing: name, product or service of interest, order data, deadlines, reference location. The quality rule is that every variable must have a reliable value for all recipients, otherwise the message goes out broken or generic.
Operationally, personalization depends on the quality of the address book: the fields used in variables must be populated and correct, because the message shows exactly what's in the database, typos included. It's worth providing fallback values for missing fields and testing the template on internal contacts before the campaign. Variables also matter in approval: Meta rejects templates with placeholders lacking sufficient context.
WhatsApp templates in SendApp support variables filled with the contact's data, from the name to address book fields, both in mass campaigns and in automated messages.
