# Approvals from Slack and email.

Later: in the public beta you approve in the app, and this switches on after it. Then you can keep Propel moving without opening the app. A daily email lists what is waiting, with Approve and Reject buttons. Slack notices have the same buttons, plus Answer. When it asks a question by email, reply in your own words and it reads the answer.

Opening soon Propel isn't open for sign-up yet. This guide shows how it works on day one. [Join the waitlist](https://runpropel.com/waitlist) to get in first.

Approvals from Slack and email are not in the public beta. They switch on after it, and work as below.

## How do email approvals work?

- One summary a day, at the hour you choose (8 in the morning unless you change it), only when there is something to say.

- Each piece waiting has Approve and Reject buttons. Each button works once and expires after 72 hours.

- When Propel asks you a question by email, reply from your own address and it reads your answer. A reply answers a question; it does not approve a piece.

## How do Slack approvals work?

- Connect Slack to your workspace.

- Link your own Slack account with /propel link .

- Notices arrive with Approve , Reject and Answer buttons, and quotes with Go ahead and Not now . Each button is tied to you and works once.

## What if nobody answers?

A job waiting on you gets one reminder after a day. A job that started on its own and waits three days with no answer stops, so nothing happens long after you stopped looking.

## Questions about this guide

### Can I approve by replying "yes" to the email?

Not today. Replies answer questions. Approvals use the buttons in the email or in Slack.

### Can someone else press my approval button?

Slack buttons are tied to the person they were sent to, and email buttons work once and expire after 72 hours.

### Can I change when the daily email arrives?

Yes. Pick the hour; it arrives once a day at that hour in your time zone, only when there is something to say.
