| Letterhead | Letterhead is the name of our platform. A newsletter creation and distribution tool that helps you build, manage, and grow email newsletters with ease. Learn more! |
| Advertiser | An external party (a business, brand, or sponsor) that pays to place an ad or promotion in your newsletter. They are not part of your organization—they're buying visibility from you. |
| Auto-inject |
Auto-Inject is a feature for promotions that automatically places a promotion in a specific section of your newsletter, such as the header, hero, mid-body, bottom-body, or footer based on the placement selected at promotion creation. Instead of manually dragging a promotion block, the system injects it for you when the promotion date is selected in Step 2 of the newsletter creation. Auto-injected promotions are locked in place to prevent accidental changes, which is especially useful when specific placement has been promised to an advertiser. |
| Audience | Your audience is the full list of contacts, regardless of their status, such as subscribed, unsubscribed, pending confirmation, pending disengaged, disengaged, cleaned, or not subscribed. |
| Block | A block is a content section you add in the composer when building a newsletter. Each block can include different types of content, such as text, images, links, articles, or promotions. |
| Company | A company is your dedicated workspace within Letterhead. Each company has its own organizations and channels. Your company is accessed via a unique URL, like yourcompanyprefix.app.tryletterhead.com. |
| Composer | Letterhead's tool for creating and scheduling newsletters. |
| Channel | A channel is where you create and manage individual newsletters. Each channel has its own settings, content, audience, and send schedule. Channels can be customized independently, but they also inherit certain settings from the organization level. |
| Curator | The person responsible for selecting and organizing the content that goes into a newsletter. |
| Curations Library | The Curations Library is where saved articles are stored for future use in your newsletters. These articles can be added through the browser extension, API, RSS feeds, or other integrations, making it easy to reuse and organize content across issues. |
| Default Promotion Type | The common promotion types that are serviced by Letterhead. |
| Email Subject | The subject line is the main title of your email, shown in your audience's inbox. It's one of the first things recipients see and plays a key role in encouraging them to open the newsletter. |
| Newsletter | A newsletter is a curated email sent to your audience on a regular schedule. It can include articles, announcements, promotions, links, and other content. |
| Organization | An organization (also called a brand) is the top-level account where you manage global settings, create promotions, and view data across all channels. Settings made at the organization level apply to all channels under it unless overridden. It gives you a centralized overview of your entire newsletter operation. |
| Prefix | The unique identifier that appears at the beginning of your company’s URL in Letterhead. You will receive this from support when joining Letterhead. For example, in yourcompanyprefix.app.tryletterhead.com |
| Preview Text | Preview text appears next to or below the subject line in the inbox. It gives recipients a short summary or teaser of what’s inside the newsletter, and can help boost open rates when written effectively. |
| Promotions | Promotions are paid, sponsored content that appear within your newsletter and are used to promote products, services, events, or other offerings to your audience. |
| Promotion Type | A unique structure for a promotion; each promotion type carries properties, for example, a banner promotion type includes a 728x90px image and a link. |
| Sending | A status that indicates the newsletter is still in the process of being delivered. If it's marked as "Sending," it means fewer than 75% of recipients have confirmed delivery so far. |
| Scheduling | "Scheduling" is an unofficial status that appears when a newsletter reaches Step 2 in the send flow but is never fully scheduled. It acts as a warning that the issue is in progress but hasn't been assigned a send date or time. |
| Spam Complaint | A spam complaint occurs when a recipient reports your email as unwanted or spam, typically by clicking the "Report Spam" or "Junk" button in their email client. |
| Templates | A newsletter template is a reusable layout that includes pre-arranged content blocks to help you quickly set up a newsletter. Use templates to save time and maintain consistency |
