# Set up Iterable templates for Jacquard

For Iterable marketers. Link the Jacquard data feed to a template once, then add Jacquard fields with fallbacks anywhere in the email.

**Placeholders:** example values (for example names in code) and values in angle brackets are account-specific. Your Jacquard contact provides them.

**Existing customers:** don’t change existing templates or unlink their feeds. Use this guide for new touchpoints only.

## Template setup

For the team that builds Iterable templates.

### 1.1 Before you start

1. **Prerequisites**
  - Technical setup complete, including the data feed for this touchpoint.
  - Touchpoint created (or imported) and content approved in Jacquard.
2. **Get the field keys**

From the touchpoint’s **Connect** tab. Keys match the response, for example `subject_line`, `preheader`.

### 1.2 Link the data feed to the template

1. **Open the template**

In the email template, go to **Settings > Data Feeds**.
2. **Select the Jacquard feed**
  - Select the Jacquard data feed for this touchpoint.
  - Leave **Merge the data feed and user contexts** unticked. Feed fields then use `[[ ]]`.
  - Turn caching off so each recipient gets their own variant.
3. **Once per template**

Link the feed once. Its fields can then be used anywhere in the email.

### 1.3 Add Jacquard fields to the email

| Part | Reference |
| --- | --- |
| Subject line | `[[content.fragments.subject_line]]` |
| Preheader | `[[content.fragments.preheader]]` |
| Other parts (headline, CTA, body) | `[[content.fragments.field_key]]`, key from the Connect tab |

1. **Subject line**

Add to the subject line:

```plaintext
[[#if content.fragments.subject_line]]
[[content.fragments.subject_line]]
[[else]]
YOUR CONTROL COPY
[[/if]]
```
2. **Preheader**

Add to the preheader:

```plaintext
[[#if content.fragments.preheader]]
[[content.fragments.preheader]]
[[else]]
YOUR CONTROL COPY
[[/if]]
```
3. **Other parts**

Use the same pattern for each part Jacquard controls, for example:

```plaintext
[[#if content.fragments.headline]]
[[content.fragments.headline]]
[[else]]
YOUR CONTROL COPY
[[/if]]
```
4. **Fallback**
  - The `[[else]]` copy is used if Jacquard returns no content for that part.
  - Use your control copy from Jacquard.
5. **Personalisation**
  - Jacquard copy can contain merge tags, for example `{{first_name}}`.
  - The matching user fields must exist in Iterable.
  - Check merge tags render in a proof.
6. **Save**

Save the template, then re-save each triggered campaign that uses it.

### 1.4 Push templates

Skip if Jacquard only optimises email.

1. **Link the feed**

Link the Jacquard feed to the push template, as for email.
2. **Add the fields**

Use the same pattern in title and message, with the push field keys from the Connect tab.
3. **Test**

Re-save triggered campaigns. Send to a test device and check nothing is truncated.

### 1.5 Test and go live

1. **Send a proof**

All Jacquard-controlled parts should show Jacquard copy, not fallback.
2. **Activate in Jacquard**

Approve the experiment plan and activate the touchpoint.
3. **Launch in Iterable**

Launch or activate the campaign.

## Reference

### Response and troubleshooting

Example data feed response. Message copy is under `content.fragments`.

```plaintext
{
  "touchpoint_id": "1cd96c96-…",
  "experience_id": "6be63acd-…",
  "is_control_group": false,
  "content": {
    "channel": "email",
    "fragments": {
      "subject_line": "{{first_name}}, take 50% off all cycling products",
      "preheader": "Bring more energy to your rides without paying full price."
    }
  },
  "tracking": { "request_id": "33fec309-…" }
}
```

#### Troubleshooting

**Fallback copy shows**

Check the field key matches the Connect tab and the path starts `content.fragments.`

**Raw** `[[ ]]` **text shows**

The feed isn’t linked to this template, or merge contexts is ticked. If ticked, use `{{ }}` instead.

**Every recipient gets the same variant**

Turn data feed caching off.

**Merge tag shows as text**

For example `{{first_name}}`. Report to your Jacquard contact with the template ID.

**Triggered campaign shows old template**

Re-save the campaign.
