# Using Your One-Click Opt-In Link with Klaviyo

The opt-in link allows you to add existing subscribers from your Klaviyo list directly into a PerkZilla campaign with a single click — no re-confirmation required.

2. Click **Opt-in Link** in the left menu

| Your link already includes first and last name placeholders by default. You can toggle these on or off using the First Name and Last Name buttons at the top right.

## Step 2: Replace the Email Placeholder with the Klaviyo Tag

Your link will contain `{Subscriber Email}` as a placeholder. Replace this with Klaviyo's personalization tag so each recipient's email is inserted automatically when the link is clicked.

Replace `{Subscriber Email}` with `{{person.email}}`

Your final link should look like this:
```
https://app.perkzilla.com/optin/v4/signup?u=YOURKEY&e={{person.email}}&fn={{person.first_name}}&ln={{person.last_name}}
```

## Step 3: Add the Link to Your Klaviyo Email

Paste the completed link into any Klaviyo email as a button or hyperlink. When an existing subscriber clicks it, they will be automatically enrolled in your PerkZilla campaign without needing to fill out any form.

| This works in both Klaviyo campaigns and flows — paste the link wherever you want to invite subscribers to join the campaign.
