# What Are Opt-In Settings and How Can You Configure Them? {% embed url="" %} Retainful ensures that a customer’s consent is appropriately obtained before they are added to your email list. This process helps you stay compliant with data privacy regulations such as **GDPR and CAN-SPAM.** The settings allow you to customize how consent is requested, typically through options like checkboxes, explicit consent statements, or subscription confirmations on popups or during automated workflows. ## Single Opt-in (Default Setting) * In a single opt-in process, a customer’s email address is added to your mailing list as soon as they complete the signup form. There is no need for the customer to confirm their subscription. **To access Single Opt-in settings, follow these steps:** * Go to the **Retainful Dashboard**. * Click on **Settings** at the bottom left corner. * Navigate to **Account settings → Emails → Opt-in settings**. * It will be in **Default Single opt-in** \

This helps prevent situations where people enter someone else’s email address without their consent. **To access Double opt-in settings, follow these steps:** * Go to the **Retainful Dashboard**. * Click on **Settings** at the bottom left corner. * Navigate to **Account settings → Emails → Opt-in settings**. * Select the **Double Opt-in** * Customize the **double Opt-in template** * Click on **Save** {% hint style="info" %} Note: 1.
