What Sponja writes to your Kit account

Sponja uses Kit's own primitives: Broadcasts, Sequences, Tags, Custom fields, and Subscribers. Everything lands in your account, in your control, nothing locked in.

  • Broadcasts for one-off follow-ups

    A single follow-up email becomes a real Kit Broadcast, created as a draft and targeted to the event's attendee tag. Every attendee sees their own subject line and body, rendered by Kit at send time.

    • Lands as a draft, you press send
    • One Broadcast, personalized per attendee
    • Sent from your existing Kit sender

  • Sequences for multi-step nurture

    A multi-step follow-up (2 to 4 emails) becomes a real Kit Sequence. Each email is a draft step with a sensible default send delay, and every attendee is enrolled automatically.

    • Default step delays you can edit in Kit
    • Each step personalized per attendee
    • All steps land as drafts in Kit's editor

  • Personalized for every attendee

    Sponja writes each attendee's subject and body into Kit custom fields, then references them with Kit's native merge tags. One Broadcast or Sequence renders a unique email for every person, no mail merge gymnastics on your end.

    • Kit's native merge tags
    • Unique subject and body per attendee
    • Renders correctly at send time

  • One clean tag per event

    Every attendee you push gets a single per-event tag, like "Sponja: Your March 12 Webinar - Attended". Reuse it for any future Kit campaign, not just the immediate follow-up.

    • One tag per event, no clutter
    • Buyer-intent tiers shape the copy, not your tag list
    • Compatible with your existing Kit automations

  • Subscriber-safe sync

    Attendees already on your list get the tag added. New attendees are added as subscribers, with no duplicates and no overwriting names. You choose whether to add new attendees or only tag people already in Kit.

  • Draft-first, send when you approve

    Everything Sponja writes lands as a draft. Subject lines, body copy, sequence steps, delays. Edit anything before you press send. Nothing leaves your Kit account unattended, and Sponja never sends on your behalf.

Data flow

What we read, what we write, what we don't touch

Reads from Kit

  • Your account details (to label the connection as "Connected as you@email")
  • Existing subscribers, matched by email so we add tags instead of duplicates
  • Your existing custom fields, so we reuse ours instead of creating duplicates on re-pushes

Writes to Kit

  • Broadcasts (as drafts)
  • Sequences (draft steps with default delays)
  • Tags (one per event)
  • Custom fields (per event, holding each attendee's personalized copy)
  • Subscribers (new attendees only, no overwrites)

Does not touch

  • Your existing automations or visual workflows
  • Broadcasts or sequences you've already sent
  • Your existing tags, fields, or subscribers (we add, never delete or rename)
  • Your forms, landing pages, or products
  • Anything outside the webinar follow-up you choose to push
Setup

Connect Kit and send your follow-ups

Connect Kit once and it covers every future webinar, on any Kit plan including the free tier. Here is the whole flow, from connecting to hitting send.

  1. Connect Kit

    From your workspace settings, connect Kit as your email tool and approve the one permission on Kit's hosted screen. You land back in Sponja showing "Connected as your-kit-email". You can also install Sponja straight from the Kit App Store, which runs the same connection.

    • Settings → Integrations → Email tools → Connect Kit
    • A single public scope, no send permission
    • Revoke anytime from your Kit account

  2. Review your drafts in Sponja

    After each webinar, Sponja scores every attendee and drafts a personalized follow-up for each one. Open the event's Followups tab to read them and tweak anything. Editing is optional, the drafts are ready to go.

    • One personalized subject and body per attendee
    • Edit in Sponja before you push

  3. Push to Kit

    Click Push to Kit and choose how to handle your attendees: subscribe new people and tag everyone, or only tag attendees already in Kit. The push runs in the background, with the status moving from queued, to pushing, to pushed, and a link straight to your draft.

    • Two audience options at push time
    • One push per event, then you edit and send in Kit

  4. Find your draft in Kit

    Click the link Sponja shows once the push finishes, or open the campaign from your Kit dashboard. Use Kit's Preview to step through individual attendees. Each preview shows that person's own subject and body, rendered from their custom fields.

    • Draft appears in Kit Broadcasts or Sequences
    • Preview steps through real per-attendee content

  5. Review and send

    When it looks right, send the broadcast, or send yourself a test first. For a multi-step sequence, review each email step and publish them from your Kit dashboard. Your attendees are already enrolled, and nothing sends until you publish.

    • Send, or send a test, from inside Kit
    • Sponja never sends on your behalf

You can disconnect Kit from Sponja settings or revoke the app from your Kit account at any time. Disconnecting stops future writes immediately. Drafts already created stay in your Kit account.

Permissions

One permission. That's the whole ask.

Kit's v4 API issues a single OAuth scope. Sponja runs entirely server-side and uses that one grant only for the operations below. There is no send permission, so Sponja can never email your list on its own.

Scope
Why we need it
public

Kit v4's single OAuth scope. It lets Sponja look up and add subscribers, create and apply the per-event tag, create the personalization custom fields, and create your Broadcast or Sequence as a draft. Every call is made from our servers with a bearer token, never from your browser.

Your Kit access token is stored server-side, encrypted at rest, and never exposed to browser code. Sponja never sends emails directly. Everything it writes lands as a draft inside your Kit account, and you can revoke access from Kit at any time.

FAQ
