# How to configure double opt-in

> Write the confirmation email, turn on double opt-in for each contact source, and make new subscribers confirm before they receive any campaign email.

Product: Kelune CRM Self-hosted (hosted by you). Page: https://kelunecrm.com/docs/wordpress/contacts/double-opt-in

Double opt-in keeps a new contact in **Pending** status until they confirm their subscription from an email. Pending contacts do not receive campaigns.

Configuration has two parts: prepare the confirmation email, then enable double opt-in for each contact source that should use it.

## Configure the confirmation email

1. Open **Kelune CRM → Settings → Double Opt-in**.
2. Enter the email **Subject**.
3. Write the **Email Body**.
4. Insert `{{confirmation_url}}` where the confirmation link should appear.
5. Optionally enter a **Redirect After Confirmation** URL.
6. Select **Save Settings**.

The email body must contain `{{confirmation_url}}`. Without that placeholder, the contact has no link to complete confirmation and Kelune CRM will not save the message.

Available placeholders include:

- `{{first_name}}`
- `{{last_name}}`
- `{{email}}`
- `{{business_name}}`
- `{{confirmation_url}}`

> **Tip:**
>
> Send confirmed contacts to a simple welcome page that explains what they subscribed to and what to expect next. Leave the redirect blank to use Kelune CRM's built-in confirmation page.

## Enable double opt-in for a source

1. Open **Kelune CRM → Settings → General**.
2. Find the contact-capture source you want to configure, such as WordPress registration or comment-form opt-in.
3. Enable that source and choose any default lists or tags.
4. Turn on **Require email confirmation (double opt-in)**.
5. Save the General settings.

Repeat these steps for each supported source that should require confirmation. Enabling double opt-in for one source does not automatically enable it for the others.

## What the contact experiences

1. The source creates the contact with **Pending** status.
2. Kelune CRM sends the configured confirmation email.
3. The contact selects the confirmation link.
4. Kelune CRM confirms the subscription and sends the contact to the configured redirect or built-in confirmation page.

> **Note:**
>
> The confirmation email settings do not enable double opt-in by themselves. The requirement must also be switched on for the relevant source under **General**.

> **Caution:**
>
> Test the complete signup and confirmation journey before promoting a form. Confirm that the message arrives, the link works, and the final page is appropriate.
