### Account & people

- **Subscriber** — a contact who is opted in to receive at least one of your subscription types.
- **List** — a static group of contacts you build for targeting (e.g., "Webinar Registrants March 2026"). You add and remove members manually or by file import.
- **Subscription Type** — a category of email a contact can opt into or out of (e.g., "Weekly Newsletter," "Special Promotions").

### Content

- **Content Pool** — the collection of articles available for your upcoming newsletter.

- **Whitelist** — keywords that articles must contain to be included.
- **Blacklist** — keywords that exclude articles from being included.
- **Custom Tags** — tags you add manually to articles. These are internal but help rasa.io's AI understand article topics.

### Scheduling

- **Frequency** — how often your newsletter sends: Weekly, Biweekly, or Monthly.
- **Cutoff Offset** — how many hours before send rasa.io stops automatically pulling content from your sources. You can still add content manually until the newsletter generates.

- **Skip** — telling rasa.io to skip a specific send without changing the overall schedule.

### Layout & design

- **Layout** — the visual structure of your email (header, content arrangement, footer). Used to be called a "template."
- **Standard template** — drag-and-drop modules with four pre-built options: Classic, Newspaper, Insights, and Big and Bold. Recommended for most customers; optimized for all email clients, low maintenance.
- **Drag-and-drop builder** — custom template builder for clients who want more flexibility and are willing to spend more time maintaining the template.
- **Custom HTML Template** — a fully custom HTML layout you build or upload, using rasa.io's special tags to insert dynamic content. For clients with very specific brand design requirements and access to HTML expertise.

### Deliverability & analytics
