For teams and client work on Notion

delivered to your team and clients automatically.

It even reaches clients who don’t use Notion by email — and their reply updates Notion.

Sound familiar?

Teammates aren’t checking Notion, so due dates slip past

Clients don’t use Notion, so you end up chasing them by email by hand

Notion reminders only reach you — so following up stays your job

All that “outside-Notion” follow-up? Kapsel handles it for you.
WHAT IS KAPSEL

The outbound notification layer for Notion

Notion is where information lives. Kapsel is what delivers it to people — your teammates, and clients who don’t use Notion.

No Notion needed — email + one-click confirm

Kapsel doesn’t just send — a recipient’s one click writes back to Notion. Unlike native reminders or Slack, it connects two-way even with people who don’t use Notion.

EXAMPLE

What they get is one email with a button

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

Their click updates the status automatically

BEFORE / AFTER

From “chasing every day” to this

Before

11 PM, staring at a follow-up draft

Writing and deleting for 15 minutes so it won’t sound harsh. Then waiting on a reply, unable to focus.

With Kapsel

You do nothing — and it still runs

Reminders and confirmations are automatic. One click updates Notion, and the chasing stops.

REASON

Why Notion teams choose Kapsel

Reason01

It reaches people who don’t use Notion

Clients and partners only need email — no app, no sign-up, no login. So it works no matter who’s on the other side.

No NotionConfirm by email
Reason02

It never sends to done or paid

Right before sending, Kapsel checks Notion again. If it’s “done” or “paid,” it doesn’t send — preventing the scariest mistake: double-chasing a client.

Reason03

Replies land back in Notion — zero manual checking

Recipients just tap a button. The status updates in your Notion database, so the whole team sees the latest state instantly.

Notion and Slack mostly notify people who use Notion. Kapsel reaches everyone — including clients — two-way.

USE CASE

For teams and client work alike. Where it fits

Internal

Team tasks & deadlines

Remind each assignee before the due date. Follow up when overdue; done syncs back to Notion.

External

Client & partner progress

Ask for confirmation by email even if they don’t use Notion. Great for waiting on assets or reviews.

External

Invoice & payment follow-ups

From the first notice to reminders — automatic. Never sends to people who already paid.

Internal

Weekly progress & check-ins

“Every Friday, send unfinished items to each owner” — recurring sends keep the team moving.

FUNCTION

Key features

Merge fields in your words

{{assignee}}, {{task}} is due {{due}}” — click a column name to drop it into the message.

Staged reminders

3 days before, the day before, the day of — pick multiple timings with a click.

Overdue follow-ups

After the due date, follow up at a set interval. Stops automatically when done.

Target filtering

Filter by assignee, type and more so only the right people get emailed.

Auto-stop

Skips anything done or paid. Zero double-chasing.

It’s your data — so it’s built to connect safely

Both the Notion connection and email sending are designed to avoid mistakes.

Official OAuth

Disconnect anytime

One click to disconnect stops every send immediately.

Deliverability & compliance

Adds an unsubscribe link and sender identity. Once someone opts out, they’re never emailed again.

FAQ

Frequently asked questions

QDoes the recipient need anything?
A

No. If they can receive a normal email, they’re set — no app and no sign-up. To confirm, they just tap a button in the email.

QHow is this different from Notion or Slack?
A

Notion reminders and Slack notifications reach people who use Notion. Kapsel emails anyone — including clients who don’t use Notion — and their one-click reply writes the status back to Notion. It works two-way, for internal and external recipients.

QCan I send for my whole team at once?
A

Yes. Using the assignee (email) property in your database, Kapsel reminds each owner individually. “Only unfinished items, to each owner,” or “every Friday” — set it up with filters and recurring sends.

QDoes it create invoices?
A

Kapsel isn’t an invoicing tool. Keep issuing invoices with your current service — Kapsel automates the notices, confirmations and follow-ups afterward.

QDo I need a paid Notion plan?
A

No. Notion’s free plan works fine.

QWhere are emails sent from?
A

On every plan, emails are sent from Kapsel’s authenticated delivery server (notify@getkapsel.com). How the sender appears depends on your plan.

  • Free & Standard: the sender name shows your name (team or business name), and replies go to your address.
  • Pro: sender branding — set a company name, signature and logo so client emails match your brand.
QHow do I cancel?
A

Anytime. Disconnect and every send stops immediately. Anyone who opted out is never emailed again.
