Grow your Kit newsletter with an AI agent
Connect Kit (formerly ConvertKit) in one click and hand off the busywork: an autonomous agent that drafts broadcasts from your recent content, keeps subscriber tags clean, reports how your sequences perform, and turns each newsletter into social drafts. You set the autonomy, it does the work.
7-day trial · Cancel anytime
Fleece AI connects to Kit (ConvertKit) through managed OAuth and lets autonomous agents draft broadcasts and sequences, manage subscribers and tags, read form and landing-page signups, and pull sequence performance. Agents combine Kit with 3,000+ other apps — Gmail, Webflow, Google Sheets, Slack — so a new subscriber, a published post, or a finished broadcast becomes a tagged contact, a draft, or a report anywhere in your stack, under the approval rules you set.

What a Fleece agent does with Kit
Kit — the creator email platform formerly called ConvertKit — is built around broadcasts, sequences, subscribers, tags, forms, and landing pages. If you run a newsletter, most of your time goes not to writing the one email that matters but to the scaffolding around it: turning your latest post into a draft, tagging new signups correctly, pruning cold subscribers before they hurt your deliverability, and checking whether last week's sequence actually converted. A Fleece agent takes that scaffolding. It reads the state of your Kit account, drafts what you ask for, and acts on rules you give it in plain language.
Under the hood, the connection runs through managed OAuth — you authorize Kit once, and Fleece handles tokens, scopes, and refresh securely; you never paste an API key. The agent can create and update subscribers, apply and remove tags, draft broadcasts and sequence emails, read forms and landing-page signups, and pull open and click performance. Real-time triggers let it react the moment a subscriber joins through a form or a broadcast finishes sending, while scheduled flows handle recurring digests and the weekly tag cleanup.
What makes this different from Kit's Visual Automations is judgment. A Visual Automation runs the branch you dragged into place ahead of time; an agent reads the actual content — the post you just published, the tone of a subscriber's reply, the shape of your cold segment — decides what matters, and coordinates other tools to finish the job. Because Fleece agents work as a hierarchy, a lead agent facing Kit can hand research to a child agent, pull the source article from Webflow, and drop the draft in Slack for review, then report back — all under one set of approval gates.
What the agent can do in Kit
Newsletter drafting
Turns your latest post or notes into a Kit broadcast draft — subject-line options and body copy in your voice — and holds it for your one-click review before it sends.
Subscriber and tag hygiene
Finds cold segments, duplicate or inconsistent tags, and stale subscribers, then normalizes tags and proposes suppressions to protect your deliverability.
Sequence performance
Reads open and click rates across your sequences and broadcasts and writes a plain-language digest of what converted and what stalled.
Cross-channel repurposing
Takes each broadcast and drafts matching social posts — a thread, a short post, a caption — so one newsletter feeds every channel, held for approval.
Real-time triggers
Reacts the instant a subscriber joins through a form or landing page, or a broadcast finishes, through event-based triggers rather than polling.
Approval gates
Anything that reaches your list — sending a broadcast, editing a live sequence, deleting subscribers — pauses for your one-click sign-off first.
Automations creators run on Kit
These are concrete setups you can describe to a Fleece agent in plain language. Each one combines Kit with other connected apps.
Newsletter: this week's post, drafted as a broadcast
When you publish a new article on your Webflow blog, the agent reads it, drafts a Kit broadcast that summarizes and links it — two subject-line options and body copy in your voice — and targets the segment you name. It assembles the broadcast in Kit and stops. Nothing sends until you review and approve it in one click, so the draft is a head start, never an autopilot mistake.
List health: prune the cold segment without guessing
On a weekly schedule the agent scans your Kit subscribers for cold segments, duplicate tags, and long-inactive addresses. It normalizes the tag taxonomy, groups candidates for suppression, and writes a before-and-after summary to Google Sheets. Deleting subscribers or editing a live tag rule is approval-gated, so hygiene tightens your deliverability without ever removing someone by accident.
Reporting: know what your sequences actually did
Every Monday the agent pulls open and click rates for your recent Kit broadcasts and active sequences, compares them to the prior week, and posts a plain-language digest to your Slack #marketing channel while appending the raw numbers to a Google Sheets tracker. You see which sequence step is leaking and which broadcast landed, without opening a single dashboard.
Repurposing: one newsletter, every channel
After a broadcast sends, the agent drafts the social versions — a thread, a short post, a caption — reusing the newsletter's best lines and matching each channel's format. It drops the drafts in Slack for your approval and can send the polished copy back to your inbox via Gmail for scheduling. One piece of writing, repurposed everywhere, without the copy-paste tax.
How to connect Kit to Fleece AI
Create your Fleece account
Sign up and start the 7-day trial. You land in a workspace where agents, flows, and integrations live together.
Connect Kit via managed OAuth
Pick Kit (ConvertKit) from the integrations catalog and authorize it in one click. Fleece manages tokens and scopes for you; you can revoke access at any time from Kit or from Fleece.
Describe the job in plain language
Create an agent and tell it what to do — "draft a broadcast from each new Webflow post, clean cold tags every Monday, and post a sequence digest to #marketing". No Visual Automation to drag together.
Set autonomy and approval gates
Choose what the agent may do on its own and what waits for your sign-off. Anything that reaches your list pauses for one-click approval.
Run it on triggers or a schedule
Let the agent react to Kit events in real time, or schedule recurring flows — the Monday cleanup, the weekly digest — that run without you.
Kit works better with the rest of your stack
Kit automations get powerful when they cross app boundaries. Pair Kit with Webflow so every published post can seed a broadcast draft, with Gmail so replies and briefs feed your writing and finished copy lands back in your inbox, with Google Sheets so subscriber health and sequence numbers live in a running tracker, and with Slack so drafts and weekly digests reach you where you already work — all through the same agent, all under the same approval rules. Fleece connects to 3,000+ apps, so the stack you already use is almost certainly covered.
