This glossary covers the key terms you'll encounter in Kit, so you always know what's what.

Apps connect Kit to other tools you use — things like course platforms, e-commerce stores, membership sites, podcast hosts, and more. When something happens in one of those tools (say, someone buys your course), Kit can respond automatically: add a tag, start a sequence, update a subscriber's data.

Visit the Kit App Store to see all the apps you can install. You'll also find them under the Apps section in your account.

A Broadcast is a one-time email you send to a group of subscribers at a specific time. It's not automated: you write it, choose your audience, and send (or schedule) it.

Use Broadcasts for your newsletter, product announcements, event invites, or any send that isn't part of an automated series. You can filter your audience by tags, segments, or other subscriber data to make sure it goes to the right people.

The confirmation email is the first email Kit sends automatically after someone subscribes to your form or landing page. It typically contains the link they need to confirm their subscription, and can also deliver a lead magnet or freebie you've promised.

You can customize the subject line, content, and any attached incentive from the Incentive tab inside your form settings. If subscribers say they didn't receive your lead magnet, the confirmation email is usually the first place to check.

The Creator Network is Kit's built-in recommendation system. When someone subscribes to your newsletter, you can recommend other creators' newsletters — and they can recommend yours in return. Subscribers opt in to whichever recommendations interest them.

It's one of the fastest ways to grow your list with subscribers who are already interested in content like yours, because they're coming through a trusted recommendation.

Double opt-in is a setting that requires new subscribers to verify their email address before they're added to your list. When someone fills out your form, Kit sends them a confirmation email with a link to click. Only after they click that link do they become an active subscriber.

An Email sequence is a series of emails sent automatically on a schedule you set. When a subscriber is added to a sequence, they receive each email in order — spaced out by however many days you choose.

Email sequences are ideal for onboarding new subscribers, delivering a course or challenge, or nurturing leads over time. Once you build one, it runs on its own.

Forms are embeddable sign-up widgets you add to your website, blog, or other pages. When someone fills out a form, they're added to your Kit list as a subscriber.

You can customize what fields appear, how the form looks, and what happens after someone subscribes — like adding a tag, sending them to a sequence, or showing a custom confirmation message. Kit gives you the embed code; you paste it wherever you need it.

Import is how you bring existing subscribers into Kit from another platform or a spreadsheet. Kit accepts CSV files, and you can map columns to subscriber fields, apply tags on import, and choose whether to trigger confirmation emails for the contacts you're moving over.

If you're migrating from another email tool, import is your starting point — it keeps your list intact so you're not starting from zero.

Landing pages are standalone sign-up pages hosted by Kit. They work like forms, but they're a full page — with their own URL you can share anywhere, no website required.

Landing pages are useful when you want a dedicated place to promote a freebie, newsletter, or lead magnet. Kit handles the hosting, so all you need to do is share the link.

A newsletter site is a public-facing website Kit hosts for you, where your broadcast emails are automatically published as posts. It gives your newsletter a home on the web — readers can browse your archive, share individual issues, and discover your work even if they're not subscribers yet.

You don't need a separate blog or website to use it. Kit handles the hosting, and every broadcast you send can appear there automatically.

Products are digital items you sell directly through Kit — things like ebooks, courses, downloads, templates, or paid newsletters. Kit handles the checkout, payment processing, and delivery, so you don't need a separate e-commerce platform.

When someone buys a product, Kit can automatically tag them, add them to a sequence, or trigger an automation connecting your sales directly to your email system.

Rules are simple if/then automations: when this happens, do that. Each rule has one trigger and one action — for example, "When a subscriber purchases a product → add the tag 'customer'."

Rules are lighter than full visual automations. Use them for straightforward, single-step responses to subscriber events. For anything more complex — multiple steps, wait times, or branching logic — use an automation instead.

Segments are dynamic groups of subscribers that update automatically based on conditions you define. Unlike tags, you don't apply segments manually — Kit calculates who belongs in each one in real time.

For example, a segment might include "subscribers who joined in the last 30 days and haven't opened an email yet." The moment someone meets those conditions, they're in. The moment they don't, they're out.

Use segments to target the right people when sending a broadcast, or to understand what's happening across your list.

A subscriber is a person on your email list. When someone fills out your form or landing page and confirms their email, they become a subscriber in Kit.

Everything in Kit — tags, segments, sequences, automations — connects back to subscribers. Your list is the collection of all of them.

Tags are labels you apply to subscribers to organize them. They're manual: you decide when to add or remove them, either by hand or through an automation. A subscriber can have as many tags as you need.

Tags are great for capturing context about a subscriber: where they came from, what they've purchased, what topics they care about. Common examples: customer, webinar-attendee, podcast-listener.

Think of tags as the building blocks for everything else — segments, automations, and sequences all reference them.

Tips let your subscribers send you a one-time payment as a way to support your work, like a tip jar built into Kit. You share a tips link (or embed it in an email or newsletter site), and subscribers can contribute whatever amount they choose.

Tips are a lightweight way to earn from your audience without creating a full product, and they work well alongside your other revenue streams.

Visual Automations are visual workflows that trigger actions based on subscriber behavior or events. They're more flexible than email sequences: instead of a straight line, automations can branch based on conditions.

An automation might look like: "When someone fills out my welcome form → add the tag 'new-subscriber' → wait two days → if they opened the welcome email, add them to my nurture sequence / if not, send a follow-up." You build the logic once, and Kit handles the rest.

Email sequences often live inside automations — the automation determines who gets added and when, while the sequence delivers the emails.
