# Build your outreach tool, not its email

You bring the leads, the copy and the sequence. We give you the pieces it runs on.

Mail coming in passes through Categories, Suppressions. Your outreach tool is your code: Leads, copy, sequences. Mail going out passes through Pacing, Sending hours, Scheduling.

Pacing

## Warm up a new domain slowly

Queue the whole list at once. A limit per sending address lets it out a few dozen a day, the pace inbox providers trust.

[Pacing](/features/pacing)

Example: a limit of 30 a day per sending address on \*@northwind.io. A list of 150 leads queued on Monday goes out 30 a day, Monday to Friday, while the rest wait their turn.

Sending hours

## Land at nine in their morning

One hours rule per region, matched on the lead's domain: \*.de on Berlin time, \*.com.au on Sydney's. Queue at midnight and those leads hear from you at the start of their day.

[Sending hours](/features/sending-hours)

Example: a campaign queued Monday 23:40, your time, reaches Dana Ruiz (\*@\*.de, Berlin hours) and Priya Raman (\*@\*.com.au, Sydney hours) each at Tue 09:00 in their own time zone.

Scheduling

## Book the follow‑up with the intro

Schedule the second email when you send the first. Until it goes, you can move it or cancel it with one call.

[Scheduling](https://docs.aiinbx.com/guides/scheduling)

Example: the intro, “Brushed 3mm sheet for Lind Metall”, is sent Tue 09:14, and its follow-up, “Just bumping this”, is already scheduled for Fri 09:00.

Categories

## Know which replies are people

Every email that comes back is labelled. An out-of-office is not an answer, and your sequence can tell.

[Categories](https://docs.aiinbx.com/guides/receiving#categories)

Suppressions

## Stop means stop, in every campaign

Most people don't click unsubscribe, they write back. We read that as one, and no later send reaches them.

[Suppressions](/features/suppressions)

Example: Iris Kaplan replies “Not for us — please take me off your list.” She is added to your suppressions, and the next campaign, on the new 4mm range, is not sent to her.

Put together

## Your sequence, in three calls

Step 1, emails.send: the intro.

```
const intro = await aiinbx.emails.send({
  from: "nora@northwind.io",
  to: "dana@lindmetall.de",
  subject: "Brushed 3mm sheet for Lind Metall",
  text: pitch,
  unsubscribe: true,
})
```

Step 2, threads.reply: the follow-up.

```
const followUp = await aiinbx.threads.reply(intro.thread_id, {
  text: "Just bumping this",
  scheduled_at: inDays(3),
})
```

Step 3, email.received: a person answered.

```
if (event.type === "email.received" && event.data.category === "human") {
  await aiinbx.emails.cancel(followUp.id)
}
```
