## Overview

MailSlurp notifications let teams route account, billing, quota, and device-preview events to browser notifications and connected channels such as Slack and Microsoft Teams.

Open **Settings** > **Notifications** to review browser notification status, connected channels, device render rules, and account or billing rules.

## Connect A Channel

Use **Connected channels** to connect Slack or Teams before creating channel rules.

For Slack:

1. Open **Settings** > **Notifications**.
2. Choose Slack from connected channels.
3. Complete the Slack authorization flow.
4. Load channels and choose the channel MailSlurp should post into.
5. Return to **Settings** > **Notifications** and create rules for the destination.

For Microsoft Teams:

1. Open **Settings** > **Notifications**.
2. Choose Teams from connected channels.
3. Open the Teams connection link.
4. Send the prefilled connect message from Teams.
5. Return to MailSlurp and refresh the destination list.

## Account And Billing Rules

Account and billing rules can send operational events to connected destinations.

Account rules can be used for events such as plan-limit and quota-threshold notifications. Billing rules can be used for payment failures, subscription status updates, and cancellations.

Use a small number of high-signal rules first. Send alerts to a channel that an administrator or owning team actually reviews.

## Quota Alerts

Quota alerts work with organization governance policies. Create report-only or alert-only quota policies from **Settings** > **Organizations** > your organization > **Governance**, then route account quota events from **Settings** > **Notifications**.

For quota setup, see [organization governance and quotas](/docs/governance/).

## Device Preview Rules

Device preview rules notify a connected channel when render runs complete, fail, or need attention. Open **Settings** > **Notifications** and choose **Manage render notifications** to configure render-specific rules.

Use device preview notifications when email rendering evidence needs to be visible to QA, release, lifecycle, or operations channels without manually checking the dashboard.

## Testing Rules

After creating a rule, use **Test** to send a sample notification to the selected destination. If a test does not arrive:

- confirm the destination is active
- confirm the Slack or Teams channel still exists
- refresh connected channels
- check whether the rule is enabled
- use a simpler event set and test again

## Recommended Setup

Start with these rules:

- account quota threshold alerts to an administrator channel
- billing payment failure alerts to the account owner channel
- device preview failure alerts to the release or QA channel
- plan limit alerts to the workspace administration channel

Keep notification rules reviewable. Pause or delete noisy rules and use dedicated channels for ownership-heavy workflows.
