Connect inbound email to Slack

Send a channel alert when a specific project inbox receives mail. The workflow starts from Boundry's New Email trigger and posts through the Slack connection you select.

Receiving must be ready in your project.

The New Email trigger depends on regional inbound receiving. Check the selected deployment before publishing MX or enabling this workflow. The templates below are configuration recipes, not preinstalled sequences.

Check receiving setup

When to use this connection

Useful for a shared support or operations inbox where a person should see a new request quickly, without forwarding the whole message to another mailbox.

Before you start

  • Inbound receiving must report ready for the selected Sydney project before you publish its MX record.
  • Connect a Slack workspace and select a channel the app can post to.
  • Choose which message fields your team is comfortable sending to Slack.

Build it in Boundry

  1. Create a sequence and choose Boundry → New Email as the trigger.
  2. Set To address to the inbox that should alert the channel. Leave other filters empty unless needed.
  3. Add Slack → Send Channel Message and select the connected workspace and channel.
  4. Map the text below, test with a received email, then enable the trigger, action, and sequence.

Workflow template

Use these field values as a starting point, then replace the examples with resources in your own project.

New inbox message → Slack alert

Show the sender and subject in the channel, then let a person open the original in Boundry.

Expected result. One Slack message per matching inbound event. Inspect the run and Slack response before treating the alert as delivered.

Where the data goes

The trigger, mapping, run state, and logs belong to the project's regional workflow plane. The selected sender and subject leave that plane when the Slack action runs; Slack then processes them under its own terms.
