# How Automation Works

> Learn how automations work and how to create them

## Cooldown Periods

Think of cooldown like a "waiting period" before your automation can run again for the same customer.

### Why You Need Cooldown

Without cooldown, if someone enters your segment multiple times, they'd get the same email over and over. That's spam, and customers hate spam.

### Your Cooldown Options

You can configure your automation to:

#### 1. Never Run Twice

Run only once per customer, ever.

**Example:** "Welcome New Customer" email

* Customer enters segment → Gets welcome email ✅
* Customer enters segment again later → No email (already got it) ❌

#### 2. Run Always

Run every time someone enters the segment.

**Example:** "Weekly Newsletter" automation

* Customer enters segment → Gets newsletter ✅
* Customer enters segment again next week → Gets newsletter again ✅
* Customer enters segment again → Gets newsletter again ✅

#### 3. Run After Waiting Period

Wait a specific amount of time before running again.

**Example:** "Follow-up Sequence" with 7-day cooldown

* Day 1: Customer enters segment → Gets follow-up email ✅
* Day 3: Customer enters segment again → No email (still waiting) ❌
* Day 8: Customer enters segment again → Gets follow-up email ✅
