### Validate Emails in Bulk with @mailtester/core

Source: https://kazmiali.github.io/mailtester

Demonstrates how to use the `validateBulk` function to process an array of email addresses. It includes options for concurrency and progress tracking. Ensure you have imported the function from '@mailtester/core'.

```typescript
import { validateBulk } from '@mailtester/core';

const emails = [
  'user1@gmail.com',
  'user2@yahoo.com',
  'fake@mailinator.com'
];

const result = await validateBulk(emails, {
  concurrency: 10,
  onProgress: (completed, total) => {
    console.log(`Progress: ${completed}/${total}`);
  }
});

console.log(`Valid: ${result.valid}/${result.total}`);
// Output: "Valid: 2/3"
```
