Typically while configuring any WhatsApp Marketing automation or broadcast, you would replace a variable in the message template, for eg. {{1}} with a variable from the system, for eg. {CustomerFirstName}.
Let me use an example to illustrate.
Suppose the template is — Hi {{1}}, thanks for ordering from {{2}}.
Now, you can replace {{1}} with {CustomerName} and {{2}} with {BrandName}.
So the final message becomes — Hi CustomerName, thanks for ordering from BrandName.
But what if you made a mistake, or for any other circumstances you want to say — Hi CustomerName, thanks for ordering from BrandName. Have a nice day!
To achieve this, you can use the Value + Text option from the dropdown. Inside Value + Text, replace the variable {{2}} with this — {BrandName}, have a nice day.
