# Email List Validator

Validate a list of email addresses before you send to it.

## What it checks

- Syntax
- Disposable email providers
- Whether the domain has an MX record
- Role-based addresses (shared inboxes such as `info@`)
- Free email providers

Each address is returned as `valid`, `risky`, or `invalid` with a reason.

## API

```bash
curl -X POST https://www.mailmark.dev/api/tools/validate-emails \
  -H "Content-Type: application/json" \
  -d '{"emails":["alice@acme.com","bob@example.com"]}'
```
