# Understanding Double Opt-In

Double Opt-In is a **Premium-only feature** that helps ensure recipients explicitly confirm they want to receive your emails. It adds an extra layer of consent and improves both compliance and deliverability.

In email marketing, **single opt-in** means a user signs up and immediately starts receiving messages. **Double opt-in**, by contrast, requires the user to confirm their subscription by clicking a special link sent to their inbox. This prevents accidental signups, bots, and spam traps while ensuring every contact genuinely wants your messages.

### Why Double Opt-In Matters

- **Better compliance** – Meets standards under laws such as GDPR and CAN-SPAM by confirming consent.
- **Higher engagement** – Users who confirm are more likely to read and interact with future emails.
- **Cleaner lists** – Filters out typos, fake addresses, and unverified signups before they reach your CRM.
- **Fewer spam complaints** – Reduces the risk of your domain being flagged as spam.

### How It Works in Mass Email Notifications

The Double Opt-In process connects three forms:

1. **Sign-up form** – Collects the user’s initial information.
2. **Sending form** – Used later for sending mass email batches after users have confirmed.
3. **CRM or Target form** – Stores the confirmed contact record that indicates the user opted in.

When a recipient submits the signup form, they receive an email containing a merge tag link (configured on the Double Opt-In tab). Clicking that link updates their entry on the target form to mark them as **opted in**.

You can then filter your sending batches to include only confirmed recipients, ensuring messages go exclusively to verified users.

### Gravity Flow Integration

For users of **Gravity Flow**, the Double Opt-In system can be deeply integrated into your workflows.

- **Restart Workflows on Confirmation:** Automatically (re)start a workflow for the matching entry as soon as the user confirms. This allows you to trigger complex onboarding sequences immediately upon verification.
- **Delay Workflow Steps:** Pause a workflow step from proceeding until the user has successfully confirmed their subscription via the double opt-in link.
- **Workflow Step Management:** Manage "Mass Email Notification Batch" steps directly from the plugin's **Feeds** tab.

### When to Use It

- For any signup process where consent verification is legally required.
- For newsletters, donation updates, or campaigns where trust and compliance are key.
- To improve data hygiene when your form collects high volumes of public submissions.

Double Opt-In is optional but strongly recommended for any form that communicates with external audiences. It protects both your users and your sender reputation.
