# Email Accounts

> Understanding email account management and warmup

## What are Email Accounts?

Email accounts in SmartLead are the sender accounts used to deliver your campaigns. SmartLead supports:

* **SMTP Accounts**: Custom email servers
* **Gmail Accounts**: OAuth-connected Gmail
* **Outlook Accounts**: OAuth-connected Microsoft 365

## Account Rotation

SmartLead automatically rotates between multiple accounts to:

* **Distribute Load**: Spread emails across accounts
* **Improve Deliverability**: Avoid ESP sending limits
* **Build Reputation**: Warm up multiple accounts simultaneously
* **Increase Volume**: Send more emails per day

## Email Warmup

### What is Warmup?

Warmup gradually increases your sending volume to build sender reputation with email providers.

### Why Warmup?

* **New Accounts**: Build credibility
* **Better Deliverability**: Land in inbox, not spam
* **Higher Limits**: Increase daily sending capacity
* **Account Health**: Maintain good reputation

### Warmup Settings

```json theme={null}
{
  "warmup_enabled": true,
  "max_email_per_day": 20,
  "daily_rampup": 2,
  "reply_rate_percentage": 30,
  "warmup_min_count": 5,
  "warmup_max_count": 20
}
```

### Warmup Schedule Example

| Day | Emails Sent | Warmup | Campaign | Reply Rate |
| - | - | - | - | - |
| 1 | 5 | 5 | 0 | 30% |
| 2 | 7 | 7 | 0 | 30% |
| 3 | 9 | 9 | 0 | 30% |
| 5 | 15 | 10 | 5 | 30% |
| 10 | 30 | 15 | 15 | 30% |
| 20 | 50 | 20 | 30 | 30% |
