SMS Introduction

Last updated 1 November 2026

The text message templates your site sends, kept in the CMS with a recipient and a short body.

The CMS keeps the text messages your site sends, such as a booking reminder or a delivery notice. Each SMS is a template with a recipient and a short body. Your code or a form sends it, filling in the details for each message.

Where to find SMS templates

In the admin, open CMS and choose SMS. The docs.insites.io instance had no SMS templates on 1 November 2026.

What an SMS template holds

Field	Meaning
To	The recipient phone number. Can use Liquid, such as a number from a form
From	The sender: a number, a short code or a name
Body	Plain text, with Liquid for details such as a name or a reference

Example template

app/smses/order_shipped.liquid

---
to: '{{ data.phone }}'
---
Your order {{ data.order_id }} has been shipped. Track it at {{ data.tracking_url }}

Keep messages short. A message over 160 characters is split into several messages, and each part is charged.

Note

The example follows the Insites Logic Engine email and SMS reference. It was not sent, because sending is a write.

Check which SMS templates exist

A developer can list the templates on an instance with a read-only query:

Query

{
  admin_sms_notifications(per_page: 3) {
    total_entries
    results { name }
  }
}

Response on the docs instance

{
  "data": {
    "admin_sms_notifications": {
      "total_entries": 0,
      "results": []
    }
  }
}

Templates you add live in app/smses/. Insites modules keep theirs inside the module and send them from module code.

Common mistakes

Writing HTML in the body. SMS is plain text.
A phone number without the country code. Store numbers in full international form.
Long messages built from Liquid. A long name or address can push the text over 160 characters.
