# Optional Email Features

Learn more about the optional email-related features that you can enable in Marketing Cloud Engagement.

The options in this table are available in **Setup** | **Email Optional Features**.

 
| Option | Description |
| --- | --- |
| Double Opt-In | Requires subscribers to confirm their email address by clicking a link in an email they receive after subscribing. |
| HTML Paste | When enabled, this option lets you create email messages and templates using the HTML paste option. |
| Text Only Email | When enabled, this option lets you specify a plain-text email part in addition to the HTML part. |
| Send Throttling | Limits the number of emails that you send during specific hours. Sends continue until all messages are sent. |
| BCC Emails | Enable messages to include blind carbon copy (BCC) recipients. You’re billed for every email you send, so if one BCC address is added, you pay for both the message sent to the To recipient and the BCC recipient. |
| From Name Drop-Down of Users | Enables the sending of email using any account user’s address as the From address. |
| Impression Tracking | Enables performance tracking for emails that contain content built by AMPscript or dynamic content in Email Studio. When you create an email using AMPscript or dynamic content, you can give each region a unique identifier for tracking and segmenting. |
| Profile Link Check | Marketing Cloud Engagement checks your emails to make sure that they include a profile center link. You can disable this check. Before you turn off this option, ensure that your emails comply with local regulations. |
| Physical Address Check | Marketing Cloud Engagement checks your emails to make sure that they include your mailing address. You can disable this check. Before you turn off this option, ensure that your emails comply with local regulations. |
| Unsubscribe Link Check | Marketing Cloud Engagement checks your emails to make sure that they include an unsubscribe link. You can disable this check. Before you turn off this option, ensure that your emails comply with local regulations. |
