If you’ve been using Kit (formerly ConvertKit) for a while, you already know how fast your tags, subscribers, and automations can multiply. One day everything feels manageable — and then suddenly you’re staring at a list of 20+ tags with no idea what belongs where.

That’s exactly what happened in my own Kit account. In one working session, I set up a complete organizational system using folders and segments — and this guide walks you through exactly how I did it, step by step.

What Are Folders in Kit?

Folders in Kit are purely organizational. Think of them like labeled drawers in a filing cabinet — they group your tags together so you can find and manage them without scrolling through a cluttered list. Folders don’t affect your subscribers or automations; they’re just a visual organization tool for you.

For example, if you sell products on Fourthwall, you might have 7 different Fourthwall tags. Without a folder, those tags are mixed in with your newsletter tags, buyer tags, and freebie tags. With a folder, they all live together under “Fourthwall Purchases.”

What Are Segments in Kit?

Segments are saved, filtered views of your subscriber list. The key difference from folders: segments auto-update in real time. As subscribers gain or lose tags, they automatically move in and out of the relevant segments.

This makes segments incredibly powerful for targeting. Instead of manually pulling a list of “buyers who are not on my coaching program,” Kit does it for you — automatically, every time you open that segment.

Step 1: Audit Your Tags First

Before creating any folders, spend 5–10 minutes reviewing your existing tags. Go to Subscribers → Tags in your Kit dashboard and write down every tag you have. Then group them on paper (or a doc) by theme:

• Purchase-related tags (e.g., products bought, platforms used)
• Membership or program tags (e.g., active members, cancelled)
• Content or lead magnet tags (e.g., freebie download, ebook buyer)
• General subscriber tags (e.g., newsletter, OG list)

This audit gives you a clear picture of what folders you actually need — and prevents you from creating folders you’ll never use.

Step 2: Create Your Folders

Here’s how to create a folder in Kit and assign tags to it:

1. Go to Subscribers in the left sidebar of your Kit dashboard.
2. In the left panel, find the Folders section and click the + button next to it.
3. Type a name for your folder (e.g., “Fourthwall Purchases”).
4. Click the Add tag(s) dropdown, change the type to Tags, then search for and select every tag that belongs in this folder.
5. Click Save.
6. Repeat for each folder.

The 4 Folders I Created (and Why)

Based on my tag audit, here are the four folders that made sense for my account — and the tags I placed in each one:

Fourthwall Purchases

This folder holds all tags related to Fourthwall product purchases. Every time someone buys an ebook or digital product through Fourthwall, they get a specific tag. Grouping all of these together keeps my purchase tags clean and easy to find.

Tags included: fourthwall-affiliate-marketing, fourthwall-newsletter, fourthwall-order, fourthwall-pinterest-on-purpose, fourthwall-side-hustle-six-figures, fourthwall-substack-101, fourthwall-supporter

Blueprint

This folder contains all tags related to my Blueprint coaching program — active members, cancelled members, and coaching-specific tags. Keeping these together makes it easy to manage program communications.

Tags included: Blueprint – Active, Blueprint – Cancelled, Blueprint Coaching

Ebooks

This folder holds my general ebook buyer tag. Note: if you have segments named after ebook titles (like “How To Blog” or “Keto Recipes”), those are segments in Kit, not tags — they cannot be added to folders. Only actual tags can go in folders.

Tags included: ebook-buyer

Subscribers / General

This catch-all folder holds general subscriber tags that don’t belong to a specific product or program. These are the tags that identify how someone originally joined my list.

Tags included: Newsletter, Ballen Blogger Subscriber, Freebie, Free Tier, OG list

Step 3: Create Your Segments

Now that your tags are organized into folders, it’s time to build segments so you can quickly see — and email — specific groups of subscribers. Here’s how to create a segment in Kit:

1. Go to Subscribers and find the All Segments section in the left panel. Click the + button.
2. Give your segment a descriptive name.
3. Click Add Filter.
4. Set the filter type: choose Subscribed to → Tags, then select the relevant tag(s).
5. Use the any / all / none matching logic as needed for your conditions.
6. For multi-condition segments, click Add Filter Group to add a second condition block.
7. Click Save.

The 7 Segments I Created (and What They Do)

1. Fourthwall Buyers

Logic: Has ANY of the 7 Fourthwall tags
Why it’s useful: Instantly see everyone who has ever purchased a Fourthwall product. Great for sending updates, upsells, or thank-you sequences to all buyers at once.

2. Ebook Buyers

Logic: Has the ebook-buyer tag
Why it’s useful: Identify subscribers who have purchased ebooks, regardless of platform. Useful for cross-promoting new ebooks to warm buyers.

3. Blueprint Active Members

Logic: Has the Blueprint – Active tag
Why it’s useful: Your current paying members. Use this segment to send member-only content, announcements, or check-ins.

4. Blueprint Cancelled

Logic: Has the Blueprint – Cancelled tag
Why it’s useful: Former members who cancelled. This is a warm win-back audience — people who already know your work and may re-enroll with the right offer or timing.

5. Buyers Not on Blueprint

Logic: Has ANY Fourthwall tag AND NONE of the Blueprint – Active tag
Why it’s useful: This is one of the most valuable segments you can have. These are people who have already paid for your products but haven’t joined your core program. They’re warm leads — perfect for Blueprint-specific email campaigns.

6. Freebie Not Buying

Logic: Has the Freebie tag AND NONE of the Fourthwall tags
Why it’s useful: These subscribers joined your list for a free resource but haven’t purchased anything. This is your largest nurture opportunity — a targeted email sequence to this group can meaningfully move the needle on revenue.

7. New Subscribers (Last 30 Days)

Logic: Subscription date after [rolling 30-day date]
Why it’s useful: See exactly who is new to your list. Use this for onboarding sequences, welcome offers, or just to get a sense of your list growth rate. Important note: Kit doesn’t currently support a true dynamic “last 30 days” filter — you’ll need to manually update the date once a month to keep this segment current.

Pro Tips for Staying Organized in Kit

Once you’ve set up your folders and segments, here are a few habits that will keep your Kit account clean long-term:

• Name tags consistently from day one. Use a prefix system (like “fourthwall-” for all Fourthwall tags) so related tags group together alphabetically and are easy to find later.
• Assign every new tag to a folder immediately. When you create a new tag, add it to the appropriate folder right away — don’t wait until your folder is buried under a pile of unassigned tags.
• Review your segments quarterly. As your business evolves, so should your segments. Add new ones, retire old ones, and update fixed-date filters like “New Subscribers.”
• Don’t over-tag. Every tag you create is something you’ll need to manage. Ask yourself: “Will I ever email just these people?” If yes, a tag makes sense. If no, you probably don’t need it.
• Use segments for email targeting, not tags. When you go to send a broadcast, use your saved segments to target the right audience rather than manually filtering tags each time.

Why This Setup Matters for Your Email Marketing

An organized Kit account isn’t just about aesthetics — it directly affects how effectively you can email your list. When your tags are messy and your subscriber groups are undefined, you end up doing one of two things: sending to everyone (which burns your list) or sending to no one (which wastes your potential).

With folders and segments properly set up, you can:

• Send hyper-targeted emails to the people most likely to buy
• Run re-engagement campaigns to warm subscribers who haven’t purchased
• Track your list growth and buyer ratios at a glance
• Build automations with confidence because you know exactly who is in each group

It’s the difference between having a filing cabinet and having a pile of papers on the floor. Same information — completely different ability to act on it.

Final Thoughts

Setting up folders and segments in Kit takes maybe 30–60 minutes for most accounts, and the payoff is enormous. You’ll spend less time hunting for the right audience before every email send, and more time actually connecting with your subscribers in meaningful ways.

If you’re just getting started, don’t try to build the perfect system. Start with 3–4 folders based on your main categories, create 3–5 foundational segments, and refine from there. Done is better than perfect — and any organization is better than none.
