10.0: Queue, schedule, and deliver outgoing mail from automations

[jstanden]

Introduction

Automations can send or schedule "transactional" (automated, event-based) email using the mail queue.

This is accomplished by creating a queued draft. The delivery of these messages can be monitored from a drafts worklist of Setup -> Mail -> Outgoing -> Queue. Temporarily failed deliveries will be automatically retried.

Creating a sample automation for creating drafts

Log into Cerb as an administrator.

Navigate to Search -> Automations -> (+).

Set the Trigger: to automation.function.

Paste the following example automation:

start:
  record.create:
    output: new_draft
    inputs:
      record_type: draft
      # See: https://cerb.ai/docs/records/types/draft/
      fields:
        type: mail.transactional
        to: [email protected]
        name: New draft
        is_queued: 1
        queue_delivery_date@date: now
        params:
          to: [email protected]
          subject: This is a queued message from a Cerb automation
          format: parsedown
          content@text:
            This is the **formatted** content of the queued message.
            
            -- 
            Example signature
            [cerb.ai](https://cerb.ai/)

You can replace [email protected] above with your personal email address for testing.

Select the Policy tab and paste the following policy:

commands:
  record.create:
    deny/type@bool: {{inputs.record_type is not record type ('draft')}}
    allow@bool: yes

Select the Run tab and click on the play icon.

You should see output like:

__exit: exit
new_draft:
  _context: cerberusweb.contexts.mail.draft
  id: "123"
  _type: draft
  _loaded: true
  _label: New draft
  name: New draft
  to: [email protected]
  token: iDqY8YKwHv
  updated: "1619656737"
  worker_id: "0"
  subject: New draft

If you navigate to Search->Drafts, you'll see a new outgoing message in the queue.
