Email marketing built for creators who move fast

EmailMarketingAutomationEcommerceSales

Kit is the email marketing platform built for professional creators — bloggers, course sellers, podcast hosts, and consultants — who need subscribers segmented, sequences running, and broadcasts hitting inboxes without touching a CMS. Connect Kit to Actionist and your agents can add subscribers to the right form at the moment of intent, tag contacts as signals arrive from other tools, enroll them in sequences triggered by purchases or events, and unsubscribe churned contacts the instant they opt out. Every action is traceable, every transition is auditable, and your list stays clean without manual hygiene.

Eliminates manual work. Kit automation removes the human coordination required to route new contacts from checkout flows, webinars, and CRM stage changes into the right form, tag, and sequence — work that otherwise demands cross-referencing three platforms per lead.

New customer into Kit sequence in 60 seconds

When a support ticket with 'new-customer' type arrives in Gmail, your agent looks up the contact in Kit, confirms they haven't already started onboarding, then enrolls them in the 'Welcome — Customer Success' sequence and books a 30-minute kickoff call on the CSM's calendar — all before the ticket queue refreshes. The Slack #cs-team channel gets a pinned message with the customer name, plan tier, and calendar link so nothing falls through the cracks.

Connect

How to plug Kit into Actionist

Pick the connection method that suits your environment.

The fastest path — install Kit's MCP server in one click and your agent connects via a permissioned OAuth handshake, gaining access to subscribers, tags, sequences, and broadcasts. No API tokens to rotate or scope to manage.

1
Open the Apps tab

Find Kit in the Apps library and click Connect. MCP is selected by default.

2
Authorise in Kit

A Kit OAuth window opens — sign in with your Kit account and approve the requested scopes (subscribers, tags, sequences, broadcasts). You'll be redirected back to Actionist.

3
Test the connection

Actionist runs a read-only call to verify the handshake. You're ready.

FAQs

Questions about Kit + Actionist

Which Kit connection method should I use — MCP or API Token?
Use MCP unless you're running Actionist in a headless or CI environment. MCP handles OAuth automatically, scopes permissions to exactly what the agent needs, and lets you revoke access from Kit's connected apps page. API Token is better when your agent runs without a browser session or when you need to pin a specific permission set for a service account.
Can the agent write to Kit subscribers without triggering automations?
No — Kit's API applies the same automation rules as the UI. When the agent adds a tag or enrolls a subscriber in a form, any Kit automation listening to that event will fire. If you need to suppress automations, use the API Request (Beta) action to call Kit's bulk import endpoint, which has a skip_opt_in_confirmation flag that bypasses some welcome sequences. Test in a staging account before relying on this in production.
What happens if the agent adds a subscriber to a form they've already joined?
Kit treats a duplicate form subscription as a re-subscription and re-triggers the form's associated sequence from step 1. This is usually not what you want. Use the Find Subscriber action first to check the subscriber's existing tags and sequence enrollments — if they're already in the relevant track, skip the Add to Form call to avoid resetting their progress.
How should I handle Kit API rate limits in high-volume workflows?
Kit's V4 API enforces a rate limit of 120 requests per minute per API key. For bulk operations — such as importing a webinar attendee list — use the List Subscribers action to batch reads, and add a 500ms delay between write operations when processing more than 50 contacts. For imports over 500 rows, consider using the API Request (Beta) action to hit Kit's bulk CSV import endpoint, which counts as one API call regardless of row count.
Which subscriber fields can the agent read and write through Actionist?
The agent can read and write first name, last name, email address, all tags, all sequence enrollments, and any custom fields you've defined in your Kit account. Custom fields must be created in Kit's UI first — the agent cannot create new custom field definitions, only set values. The Find Subscriber action returns the full subscriber object including custom field values, which you can use in downstream conditions or writes.
How do Kit triggers work — are they real-time webhooks or polled?
Kit triggers in Actionist are real-time webhooks. When you activate a trigger (New Subscriber, New Purchase, Subscriber Added to Tag, etc.), Actionist registers a webhook endpoint with Kit's V4 API. Kit delivers the event payload within seconds of the action occurring. There is no polling interval. If you disconnect and reconnect, any events that fired while the webhook was inactive are not replayed — they are lost.
Can I use Kit triggers and actions together in the same workflow without causing a loop?
Yes, but design carefully. A workflow triggered by 'Subscriber Added to Tag' that then calls 'Add Tag to Subscriber' on the same subscriber will loop if it adds the same tag — Kit will fire the trigger again. Use a different tag for the agent's output (e.g., trigger on 'interest:product', write 'nurture-enrolled'), or add a Find Subscriber pre-check to verify the output tag doesn't already exist before writing it. This two-safeguard pattern eliminates loops without complex branching.
What Kit objects does Actionist cover, and what's not yet supported?
Actionist covers subscribers (read, write, tag, sequence, unsubscribe), forms (list, add subscriber), sequences (list, enroll, remove), tags (list, create, add, remove), purchases (create/update), and broadcasts (create). Not currently covered: editing or scheduling broadcasts, managing landing pages, custom field definitions, reporting/stats endpoints, or subscriber imports via CSV. Use the API Request (Beta) action to reach any Kit V4 endpoint not listed above.
