Sending

# Watch what happens after send delivered or not

See what happened to every send, and keep dead addresses out of the next one.

Delivery

Code omar@lumen.io Skipped

Delivered 129

Bounced 3

Complained 1

Failed 0

Blocked omar@lumen.io Held back

A bounce holds the address back. The next send skips it until you allow it again.

How it works

## Running in three steps.

1. 01
   
   Send as usual
   
   From the composer, your own code, a rule or the queue.
2. 02
   
   Read the outcome
   
   Delivered, bounced, complained or failed, by day, source and sending address.
3. 03
   
   Clear the list
   
   Bad addresses are held back, and you can allow one again.

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.

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.

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.

See when mail you sent was opened

Whether a message you sent has been opened, when, how many times and which of its links were followed. On unless you turn it off, and plain about the readings it cannot get.

Analytics & graphs

What your mailbox is actually doing, drawn rather than guessed at.

62 on Monday · 38 still waiting on you

Templates

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