How to Connect ConvertKit to Claude for Email Marketing Insights

You connect ConvertKit to Claude by adding Windsor’s native connector inside Claude and linking your ConvertKit account through Windsor.ai’s free onboarding flow. Once the two are linked, Claude can read your ConvertKit forms, broadcasts, sequences, subscribers, and tags directly, so you can ask about your email setup in plain language instead of clicking through the ConvertKit dashboard tab by tab.

The native way is worth using instead of exporting CSVs or copying data by hand, because a manual export is a static snapshot the moment you download it, and it sits in a spreadsheet disconnected from everything else you run. Connecting through Windsor.ai keeps Claude looking at your live ConvertKit setup, and lets you blend it with other tools in the same conversation instead of juggling separate exports.

2 steps to connect ConvertKit to Claude

Takes under a minute, no code or manual CSV work required.

Full walkthrough in Windsor’s documentation on integrating data into Claude.

Prerequisites

• A Windsor.ai account (free forever plan, no credit card, or paid plans from $19/month).
• A ConvertKit account with at least one form, broadcast, or sequence already set up.
• A Claude account with access to connectors.

Step 1. Connect ConvertKit to Windsor.ai

• Create your free account at onboard.windsor.ai/app/convertkit.
• Select ConvertKit as the data source.
• Authorize Windsor.ai to read your ConvertKit account.
• Repeat the authorization step if you manage more than one ConvertKit account, for example across multiple creator brands or client accounts.

Step 2. Add the Windsor.ai connector in Claude

In Claude, open Customize, then Connectors. Search for Windsor and add it, one click, no URL to paste. Sign in to Windsor when prompted, then pick your ConvertKit connector from the list of sources you’ve linked.

Approve the access request so Claude can query your connected data sources. Once added, the Windsor connector appears in your Claude connectors list and is ready to use in any conversation.

Confirm the connection is live by asking Claude to check it:

List the data sources connected to my Windsor account. Do you see ConvertKit there?

If ConvertKit shows up in that list, you’re ready to query it in natural language.

The metrics that matter for ConvertKit

Metric	What it tells you
Broadcast Subject	The subject line of each email you’ve sent, useful for auditing your send history and messaging themes at a glance.
Broadcast Created Date	When each broadcast was created, letting you build a timeline of your send cadence over any period.
Form Name	The label of each opt-in form, so you can tell which forms are live across your landing pages, pop-ups, and embeds.
Form Type	Whether a form is embedded, a pop-up, a hosted landing page, or another format, useful for auditing where and how people actually opt in.
Form Archived Status	Whether a form has been retired or is still active, helping you spot stale forms cluttering the account.
Form Sign-Up Button Text	The exact call-to-action copy on a form’s submit button, handy for auditing consistency across all your forms.
Sequence Name	The name of each automated email sequence, the backbone of your nurture and onboarding flows.
Sequence Hold Status	Whether a sequence is currently paused, so you can catch a nurture flow that stopped sending without anyone noticing.
Sequence Repeat Status	Whether a sequence re-triggers for returning subscribers, important for telling evergreen flows apart from one-time onboarding sequences.
Subscriber State	Whether a subscriber is active, cancelled, or bounced, the core health signal for the size and quality of your list.
Subscriber Created Date	When each subscriber joined your list, letting you track list growth over any time period.
Tag Name	The label applied to segment subscribers by behavior or interest, key to how you organize targeting across campaigns.

What to ask Claude: prompt ideas

Email campaign performance

List the subject lines and created dates of my last 15 ConvertKit broadcasts.

Group my ConvertKit broadcasts by month and show how many I sent each month this year.

Subscriber growth and engagement

Show me how many new ConvertKit subscribers joined each month for the last 6 months, broken down by subscriber state.

List my ConvertKit tags and tell me which ones were created most recently.

Sequence and automation performance

List all my ConvertKit sequences and flag any that are on hold so I can catch broken automations.

The ConvertKit connection through Windsor is read-only. Claude can describe and inventory your forms, broadcasts, sequences, subscribers, and tags, but it can’t create, edit, or send anything back to ConvertKit.

Bonus: analyze ConvertKit alongside your full stack

Windsor connects 350+ sources, so ConvertKit doesn’t have to live in its own silo. A few realistic blends:

• Blended cost per subscriber. Combine ConvertKit’s subscriber growth with your Facebook Ads and Google Ads spend to get a real cross-channel cost-per-subscriber instead of judging list growth against each ad platform in isolation.
• On-site behavior after the email. Pair ConvertKit broadcast and sequence activity with GA4 to see what subscribers actually do on your site after they open a campaign or move through a sequence.
• List growth from organic content. Blend ConvertKit subscriber and tag data with your Instagram content performance to see which posts are actually pulling people onto your list.

Other ways to connect ConvertKit to Claude

Manual CSV export

ConvertKit lets you export subscribers and some list data as a CSV, which you can then upload into a Claude conversation. This works for a one-off question, but it’s a static snapshot from the moment you exported it, and you have to repeat the export by hand every time your forms, broadcasts, or tags change.

Zapier or Make

You can also wire ConvertKit into Claude indirectly through a Zapier or Make automation, triggering on new subscribers, tags, or broadcasts. That’s a workflow worth maintaining if you already have one, but it still means building and keeping up a separate automation rather than asking Claude directly.

Neither option gives Claude the live, ask-anytime view that the direct Windsor.ai connection does.

Conclusion

Connecting ConvertKit to Claude through Windsor.ai takes a couple of minutes and gives Claude a live view of your forms, broadcasts, sequences, subscribers, and tags, so you can ask about your ConvertKit setup the same way you’d ask a colleague who has the dashboard open. It’s read-only today, so it’s best used for inventorying and describing your account rather than managing campaigns, but it’s the fastest native way to get ConvertKit’s structural data in front of Claude.
