Rules

Invoice 2214 for August Invoices Archive

1 Subject has invoice Stop 24 +1

2 From domain is pinefield.dev 61 +1

3 Has an attachment 9 +1

Rules run as mail arrives. Nothing already in the mailbox moves.

How it works

## Running in three steps.

1. 01
   
   Write the rule
   
   Conditions on the arriving message, then the actions to take.
2. 02
   
   Try it first
   
   Run it over the last thirty days without touching a message.
3. 03
   
   Turn it on
   
   It runs on arrival, and the log says what happened.

What it runs on

## The parts doing the work.

Nothing here is a separate product. Each one is a piece of the mailbox you already have.

Rules you write yourself

Your own conditions, and what should happen to anything that matches them.

Webhooks

Tell your endpoint when mail arrives, instead of making you poll.

/threads?query=invoice

{ "threads": 12 }

Same mailbox, whether a person or a program is holding it.

REST API

A documented HTTP API with issuable, scopable, revocable keys.

/threads?query=invoice

{ "threads": 12 }

Same mailbox, whether a person or a program is holding it.

Typed SDKs

A TypeScript client first, then the rest.

/threads?query=invoice

{ "threads": 12 }

Same mailbox, whether a person or a program is holding it.

Labels

Name a label, pick a colour, and filter the list down to it.

Templates

A body written once, versioned, and sent many times: from the composer, from your own code, or by an agent.
