Bulk Send via CSV
Send a template to a whole list at once, with each recipient getting their own personalised values. You provide a CSV; iSMS fills the template variables row by row.
How the CSV maps to the template
From Template List, click Actions → Send and choose Bulk Send via CSV. The first column must be phone_number, and every remaining column must match a template variable by name.

Each row sends one message, with that row’s values filled into the template.
