# Personalise campaign emails in Infinity3

Use merge fields to include customer details and reusable custom values for shared business information.

#### Before you start

You’ll need a draft campaign and accurate contact data for any personalisation you plan to use.

#### Add a contact merge field

1. Open the campaign in **Marketing** → **Emails** → **Campaigns**.
2. Select the text element you want to edit.
3. Place the cursor where the customer detail should appear.
4. Open the merge-field or custom-value picker.
5. Select the relevant contact field, such as first name.
6. Save and review the content.

Choose fields from the picker rather than guessing their placeholder format.

#### Add shared business information

Use an existing **Custom Value** for reusable details such as a support email, website link or standard sign-off.

Custom values differ from contact fields: they hold shared information rather than a separate value for each customer.

#### Check missing information

Review what happens when a recipient has no first name or other selected detail. Use fallback options where supported, or wording that remains readable without the field.

#### Things to know

- Some placeholders require event information that a regular campaign doesn’t provide.
- Updating a shared custom value can affect other content using it.
- A generic test email may not resolve recipient-specific details as a live send does.
- Keep the required unsubscribe option in the email.

Check representative test contact data before sending to the wider audience.
