Kapsel / How it works

Live in about 2 minutes, on your current Notion

Kapsel watches your Notion due dates and emails reminders automatically. No special setup — three steps and reminders reach your team and clients alike.

This is the actual dashboard

For every connected Notion database, Kapsel watches the due date, status and recipient email. Manage rules, upcoming sends and history right here.

Kapsel dashboard: Notion connection, monthly sends and sync status at the top, then each watched database (Kapsel / Tasks) with Settings, Rules, Upcoming and History tabs, an Embed button, and sender branding settings
The actual dashboard (emails and workspace name are masked). Each database row has an “Embed” button so you can drop it into a Notion page.

Setup, step by step

A little more detail on each step.

1

Connect Notion

On Notion’s official authorization screen, pick the pages/DBs Kapsel may access. We never receive your password. Disconnect or reconnect anytime.

Connect Notion

Choose which pages Kapsel can access, then connect.

Log in with Notion to connect
2

Pick the database to watch

Choose a database and Kapsel auto-detects the “due date”, “assignee” and “status” columns. Adjust them by hand if needed — or create a date column on the spot.

Select a database
Due→Deadline (date)
Assignee→Owner (email)
Status→State
Columns detected automatically
3

Choose timing and recipients

Pick multiple send times — “3 days before, day before, day of, after due”. Send to yourself, your team’s assignees, or external contacts (an email column), and filter by owner or category.

ToClient (email column)
4

Write with merge fields

Click a Notion column name to insert a merge field. Each recipient gets a message tailored to them — no “Dear all” blast feel.

Email body
Hi {{Assignee}}, the due date for {{Task}} is {{Due}}. Please take a look.

Auto-send → writes back to Notion

Sends at the times you set. Recipients just tap a button (no app, no signup). The result writes back to your Notion status, done/paid items are never emailed again, and every send is logged.

Notion|Tasks
Sasaki (5/31)Done
Tanaka Store (6/10)Scheduled

Updates on their click. Done/paid items are never emailed.

Build your reminder cadence

From gentle heads-ups to after-due nudges. It stops automatically once an item is done or paid.

What arrives is one email with a button

The recipient just taps a button — no app, no signup — and the Notion status updates automatically.

2

Paste into Notion → choose “Embed”

Paste the URL into a Notion page and pick “Create embed”. Kapsel’s panel appears right inside the page.
