Notion doesn’t notify people. Kapsel sends the reminder on time.
It even reaches clients who don’t use Notion by email — and their reply updates Notion.
No credit card for the free plan. Upgrade only when you need to.
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
Notion is where information lives. Kapsel is what delivers it to people — your teammates, and clients who don’t use Notion.
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.
The recipient just taps a button — no app, no sign-up — and the Notion status updates automatically.
Hi Alex,
Thanks for booking with us. Just confirming your appointment tomorrow.

Their click updates the status automatically
Writing and deleting for 15 minutes so it won’t sound harsh. Then waiting on a reply, unable to focus.
Reminders and confirmations are automatic. One click updates Notion, and the chasing stops.
Clients and partners only need email — no app, no sign-up, no login. So it works no matter who’s on the other side.
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.
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.
Remind each assignee before the due date. Follow up when overdue; done syncs back to Notion.
Ask for confirmation by email even if they don’t use Notion. Great for waiting on assets or reviews.
From the first notice to reminders — automatic. Never sends to people who already paid.
“Every Friday, send unfinished items to each owner” — recurring sends keep the team moving.
“{{assignee}}, {{task}} is due {{due}}” — click a column name to drop it into the message.
3 days before, the day before, the day of — pick multiple timings with a click.
After the due date, follow up at a set interval. Stops automatically when done.
Filter by assignee, type and more so only the right people get emailed.
Skips anything done or paid. Zero double-chasing.
Who got what, and when. Your record if anything is disputed.

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.
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.
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.
Kapsel isn’t an invoicing tool. Keep issuing invoices with your current service — Kapsel automates the notices, confirmations and follow-ups afterward.
No. Notion’s free plan works fine.
On every plan, emails are sent from Kapsel’s authenticated delivery server (notify@getkapsel.com). How the sender appears depends on your plan.
